Succeeding the Old Fashioned Way: Getting It Right
By Dan Johnson, July 25, 2016

Aerotrek importer boss Rob Rollison stands in front of his EAA AirVenture Oshkosh 2016 display.
Media people (like me) flock to airshows looking for the new stories, new airplanes, new avionics, new company developments... whatever is new. Journalists pursue what's new because they believe that's what their customers readers want to read (or perhaps because it interests them as a writer). Nevertheless, sometimes the story is what's not new. Aerotrek, importer of the A240 and A220 has not made major changes to the aircraft.

Why? Simple. The airplanes don't need to change.*

Aerotrek's planes are very well built, fly predictably and efficiently, handle nicely and perform near the top of the category at modest operation cost. They are simpler, not fancy carbon fiber, but rely on trusted construction methods using familiar materials. As important as any quality, Aerotreks are modestly priced, affordable to many budgets.

Not breaking new ground means getting familiar ways down pat, honing the building skills and techniques to a fine degree. Aeropro in Europe can execute the aircraft in a repeatably professional manner. All this may not be as sexy as a flashy new design but once aloft, being able to depend on your flying machine is worth a lot.

One more thing. Always updating a product can add to the cost of production which has to raise the selling price.

In this panorama shot, you see the entire Aerotrek display. To the left is a handsome trailer that can house an Aerotrek under which the owner drives his late-model Corvette. Nice!

Company owner Rob Rollison is a calm businessman who moves steadily toward his goals. Deep-voiced and intimately aware of his product Rob presents authoritatively with a broad smile. He has earned the trust of many airplane owners and has built a loyal following, people who have come to really like the Aerotrek aircraft and doing business with the importer.

A few of the Aerotrek owners assisting at Aerotrek's AirVentrure 2016 pose in front of a group of airplanes representing many of of the popular model variations offered.
Rob got into LSA early. He was the Flight Design CT dealer before the LSA rule was released. He has represented several brands and types over his years in business. These learning experiences brought him to Aeropro more than 13 years ago and he remains very happy with the supplier. Through the upheaval of the recession in 2008 and subsequent roller coaster ride, Aerotrek maintained a largely steady business while other company got in trouble.

At AirVenture Oshkosh 2016, Aerotrek exhibited nine airplanes on the field, challenging any other brand for most aircraft in their exhibit. You could see A220 taildraggers, A240 tricycle gear models in a number of bright colors and fitted with different landing gear from hard surface and wheel-panted tires to large tundra tires. As Aerotrek is distributor-direct-to-customer operation, the importer was aided in their Oshkosh display by owners of the aircraft available for visitors to review.

Aerotrek models come well equipped while offering a few options to allow you to personalize. All have folding wings, a task that can be done in 10 minutes ("easily") by a single person. A folded wing still supports itself through the clever design by Dean Wilson, the original creator of a good number of airplanes that look very similar. No wonder. Dean was a brilliant, efficient designer and this planform works very well. Why change what works?

* Aeropro has made numerous refinements over the years while sticking with a basic design that works well as is.


Remos GXiS — A Mercedes of LSA
By Dan Johnson, July 24, 2016

See the new Remos GXiS, a Mercedes of Light-Sport Aircraft at AirVenture 2016; spaces 331-332 near the Theater in the Woods.
Oshkosh is on! OK, not today. The big show starts tomorrow, but you wouldn't know it as airplanes are already arriving in droves and the grounds are rapidly filling. Time for EAA's summer celebration of flight to begin!

Although I'm a longtime regular, today I did something I've never done. I flew out of KOSH and then returned. If you've never flown into Oshkosh during AirVenture, you may not know what an experience such an arrival can be. This is the world's busiest airport for one week. Airplanes arrive every few minutes and all of them do so in a unique, follow-the-plane-in-front-of-you method where no pilot uses the radio. Departing was fairly simple. Arriving is always an eye-opening experience.

I did my departure and reentry with Remos PR & Marketing guy Patrick Holland-Moritz, a former German aviation magazine writer. We flew in the brand new Remos GXiS. Flying into Oshkosh was a repeat treat for me, but I think Patrick was blown away by the flowing river of airplanes of all types. This became even more interesting when the airport had to close one runway due to an incident. As on any freeway, this backed up and snarled traffic. Airplanes were circling back to get in line and our heads were swiveling on our shoulders trying to follow the traffic gaggle around us. Whew!

GXiS features the Rotax 912 iS fuel-injected engine in what may be the best-yet implementation of the fuel efficient powerplant.
Remos remains one of the major brands in the U.S. LSA fleet but the company endured a major setback in 2014 when it was declared insolvent, roughly the equivalent of U.S. bankruptcy. In the last couple years, the German company has found new investors, reorganized, and clawed its way back into the business. Spending by their American representatives in the heydays of LSA helped trigger the problem. The revitalized company has a far more realistic plan of recovery.

One thing that didn't change much was the basic Remos GX series. They have a new model now and perhaps the period they used to reorganize came with a benefit. Remos did not immediately embrace the new Rotax 912 iS fuel-injected 912. The earliest installations by other manufacturers had some challenges (as with any new product). Remos was able to design their new install after some of the earlier bumps has been smoothed. The GXiS result was good... no, make that excellent.

I have more than 120 hours experience flying with the 912 iS. It's great like all Rotax engines but it introduced complications and I experienced them. However, now that is well sorted and Remos had time to thoroughly engineer their solutions. The German engineering team said everything from the firewall forward is new, not only the cowling and spinner that you see. All electronics along with heating and cooling and other details are fresh.

In my evaluation as a pilot, this is best implementation of the 912 iS I have seen.

I'm going to write about the flying qualities but first I want to tell you about the relatively mundane matter of starting a 912 iS. Boring, huh? You might not think so after you first confront Lane A, Lane B lights and some of the other new features of the 912 iS. In their efforts to ease the transition to a computer controlled engine, Rotax made the starting and run-up process similar to what pilots are used with magneto and carb heat checks. The odd thing is that the computer is essentially already doing all this for you so the pilot's workload can be reduced. Remos engineers understood this and worked hard to make it easier.

When you rent a car anywhere in the world, you expect the car to operate simply and largely as you expect, right? Airplanes aren't so simple. While we pilots might like to show off our great knowledge, why jump through unneeded hoops?

In the Remos GXiS you turn the key switch to "Avionics" which lights up the panel but does not turn on all other electrical systems. When you switch to "Engine," all electrics are engaged and then you merely push the Engine Start button. As with many modern cars, that's it. The Rotax starts instantly as always and you can carry on with flight preparations. Remos calls the system "SMARTstart"...and it is.

While the Remos team and I discussed all these changes we understood "simplification" is too basic a term and not very sexy. True to his marketing role, Patrick created the term "smartification." Bravo! A new word is needed for this renewed LSA.

Instead of delving deeply into every change made to GXiS, let me hit some highlights. The throttle is now quadrant style instead of a knob on the panel. Throttle and brake use one lever: forward to go, aft to slow. Flaps are now preset. You move the flap-shaped lever to the position you want and go to your next task. Even cabin heating is new with a system that uses the engine's warm fluid rather than drawing from air surrounding the exhaust system. Changes go deeper so interested buyers will want to contact Remos for all the details.

Meet Team Remos from Germany at EAA AirVenture Oshkosh 2016: (L-R) Christian, Daniel, Patrick, Jürgen (kneeling), and Paul.
Finally, the flying part. Ah, this is the best (not to diminish the other excellent upgrades to the GX series).

Briefly, GXiS flies beautifully. It's been a while since I flew Remos and this is one deluxe flying machine. As my title indicates this is a Mercedes of Light-Sport Aircraft. Overall the machine is civilized and luxurious. Handling is superlative, light but not twitchy; responsive yet stable; very nice and a form of warm tribute to original designer, Lorenz Kreitmayr.

Despite approaching amid a large flock of airplanes all anxious to land after the delays on the all-in-a-line approach path, my effort with GXiS went well although I can't claim the smoothest touchdown I've ever made. Landing on one of five large dots on a runway with someone landing ahead of you and behind has a way of distracting one's concentration. Yet in control authority, I lacked for nothing and again, that smooth, easy handling pays a benefit.

Besides the SMARTstart controls everyone will love (I predict), Remos is laid out as comfortably as the interior treatment is deluxe and handsome. GXiS is not the widest cabin in the LSA fleet but was certainly comfortable. In-flight visibility is large especially while banked thanks to the large skylight.

To give some balance to my overwhelmingly positive reaction to GXiS, I note the seats adjust in three positions but only while on the ground. Baggage is accessed by removing the seats, though that's easy enough, and you have places for gear you need in flight.

The only remaining downside to the new Remos GXiS is a price tag close to $200,000. So, this won't be for everyone, but if you would consider a fine German automobile, you should by all means check out GXiS. This SLSA should satisfy even the most discerning buyers.


Flying America’s First Homegrown Modern Gyroplane
By Dan Johnson, July 22, 2016

Once upon a time... gyrocopters were an American invention. Igor Benson was such an important pioneer that many fixed wing pilots refer to all such flying machines as "Bensen gyros." Starting in the 1950s, he hit on a good combination of ideas that made the new sector flourish... for a time.

Gyros are small rotary winged aircraft that resemble helicopters in some ways — all have a spinning wing above the occupants. However, gyros work by the air moving across the blades of the rotor disk; their rotors are not powered. Most readers likely don't need a technical discussion. Suffice it to say gyros and helos are far from the same animal no matter how much they might look like one another.

Yet in the last couple decades things began to change, dramatically. Perhaps to accentuate their differences, modern producers prefer "gyroplanes" while the older Bensen types are often referred to as "gyrocopters." The old and new are different in important ways.

What's not to enjoy? The view from a gyroplane like AR1 is enormous. photo by Amy Saunders of Evolution Trikes
Europeans began to modernize older gyrocopter designs. They added solidly mounted tailplanes with greater volume, which greatly stabilized these machines. Igor Bensen's early gyros had components in the right proportion and the weight in right enough places to make his aircraft work. However, later developers made changes that lacked adequate safety enhancements and the accident rate soared. This fact alone is why many, including some in FAA, think all gyros may be unsafe; that is simply not accurate.

The Euro-style gyroplanes employ tails with larger vertical and horizontal surface area firmly attached to the rest of the carriage. Other factors are also important but the tailplane alone is a major part of why these machines are much more predictable to fly.

The Europeans also continued the development far past adding some stabilizing features. Companies across the Atlantic first partially enclosed the cockpit with half fuselages. They added better seating, instrumentation, controls, and generally improved fit-and-finish. More recently, designers have made fully enclosed models with increasing sophistication in both tandem and side-by-side seating. These improvements uncovered a ripe market.

Rotax Aircraft Engines said that in recent years, they have sold more 912 and 914 engines to the gyroplane sector than any other sector, by far. Germany's AuroGyro alone has sold more than 2,000 aircraft. Italy's Magni adds another 900 units while Spain's ELA has sold 700 units. Other producers account for another 500 making more than 4,000 sales in roughly the same time Americans have bought 3,000 SLSA of all brands.

So what is like to fly a gyro? The simplest comment is that with only a couple exceptions, you fly a gyroplane like a fixed wing. You use the stick and rudders similarly (though not identically). In my third outing — first in a Magni gyro, then an AutoGyro, and now the AR1 — I came away thinking two things. First, my fixed wing skills are highly transferrable to gyroplanes, even better than in a weight shift trike (which I also enjoy). In pursuing a full gyroplane checkout, I would not have to learn many new tricks. Secondly, gyroplanes have some clear advantages.

Something almost everyone notices at airshows is that gyroplanes can fly in winds not advised for many other aircraft. The reason, according to Greg Spicola, my instructor, is that the blades are spinning through the air at something like 400 mph. Therefore, a 25-mph crosswind is relatively insignificant. Combined with a higher wing loading, these aircraft are simply not as vulnerable to winds as most fixed wing aircraft.

Abid Farooqui's SilverLight Aviation focuses these good qualities with its American Ranger 1 by using an expanded, more effective tail arranged closer to the center of gravity thrust line. Abid explained this provides flight dynamics that reduces coupling between power and yaw and power and pitching. These changes along with a "high inertia rotor system" and a faired fuselage allow AR1 to boast a better glide ratio and energy retention, making landings easier and forgiving even for beginner pilots.

The main cautions I've heard for gyroplanes is not jamming the stick full forward (this is ill advised in a fixed wing aircraft, too). Another concern is forgetting that even after you land rather slowly, the rotor may still have quite a bit of spin remaining. If so, it is still making lift and failing to consider that could cause an upset. Likewise, a taildragger landed in a stiff crosswind also demands you handle the controls correctly. Fortunately, control actions that work in an airplane will also work for the gyro. Once the rotor is well spun down, this problem disappears.

I like gyroplane flying and I find plenty of good things to say about them. However, one of the strongest arguments involves price. SilverLight's AR1 costs only $65,000 with the 100-horsepower Rotax 912 engine. This is a kit, yes, but the build effort is modest and for a modern, comfortable, well-flying aircraft, the price is within reach of most budgets.

Since FAA has never chosen to allow Special (fully built) LSA gyroplanes, kit building is your only option. Unlike several other countries, gyroplanes like AR1 can only be sold in America as an Experimental Amateur Built kit. SilverLight said, "We have decided to offer AR1 as a package where builder assistance is offered to include airworthiness inspection fees plus the first two to three hours of test flight and tuning." An AR1 buyer travels to Zephyr Hills airport (not far from Tampa, Florida) to SilverLight's builder assist center for a nominal amount of time. The company added, "Our kit is easy and fast to put together, generally only taking two weeks to be ready for ground testing." While you put bolt A in hole B, your family can take advantage of Florida's numerous tourist attractions; it's not a bad trade and the Z-Hills airport is a fascinating place with all manner of aircraft and a very active skydiving center. C'mon down to Florida and check out the AR1 gyroplane. The view is superlative!

Pilots and Manufacturers... Help Rescuers Help You
By Dan Johnson, July 16, 2016

HYPOTHETICAL SCENARIO — You crash landed your airplane at an airport. You are unconscious inside. Emergency crews race to assist but they are worried about your airplane having a powerful rocket motor that might injure them as they try to extricate you. What do you do? More advisably, what should you have already done?

Plenty of smart aviators and nearly every salesperson will tell you safety doesn't sell. Pilots buy performance, range, sleek lines, comfort, and the latest instrumentation. Most take for granted that the aircraft is well-built and designed with stable characteristics and reliable systems. No matter their ultimate value, safety systems simply aren't sexy.

Tell that to Cirrus Design, the Minnesota startup (back in the late '90s) that did a terrific job of selling "that airplane with the parachute." Of course, their SR20 and SR22 also steadily acquired all the dazzling features they could incorporate but any Cirrus rep' is likely to agree the whole airframe parachute system, now called CAPS, was a leading reason why they did so well. The parachute set the SR20 apart from all other competitors as the new millennia began.

Truth in blogging notice: I was deeply involved with BRS parachutes when Alan and Dale Klapmeier's company had only 18 employees. Because Alan had survived a midair collision the brothers were adamant about their new baby airplane having a ballistic parachute. This history gives me a particular bias but the sales success of Cirrus is plain for anyone to see. Many thousands are flying and nearly every airport has one or many based on the field.

Recently a longtime friend and aviation business associate, Tom Peghiny alerted me to a request from Keith Leonhardt, the manager of operations and maintenance at Massachusetts' Hanscom Field airport. He wrote, "As an airport operator, we often provide our ARFF (Aircraft Rescue & Fire Fighting) crews with 'crash crew' charts for the type aircraft that are based at our airport." He asked Tom, the North American importer of CTs, "Would you happen to have any documentation that shows fuel capacity, battery location and BRS location for your fleet, particularly the CTLSi? We would like to use those documents to train on the Flight Design aircraft based at our airport." Keith was asking about documents like those accompanying this article.

You see, Flight Design wisely took a lesson from the success of Cirrus and at the insistence of Peghiny and Flight Design USA, the German manufacturer made airframe parachutes standard equipment on Light-Sport Aircraft delivered in the USA and Germany. It may be related, as it was for Cirrus, to the fact that Flight Design has sold more LSA than any other brand in America.

To show what he was seeking Keith sent Tom crash crew charts for two companies as examples. One was the set you see nearby for the now-defunct but still flying Cessna Skycatcher. The other was for Cirrus, whose models now appear on airfields all around the world.

Look. Here's why this otherwise rather mundane topic might be vitally important. A few years ago, I was one of the people described at the top of this article except the scenario was not hypothetical. See these two reports if interested: my accident and some reasons. BTW, that happened about 10 years ago. I'm doing fine and flying as often as possible. Kudos to the doctors and others in the health care industry.

I don't bring up this personal story for any reason except than to say, "IT CAN HAPPEN TO YOU." You may not think it will ever happen to you, and, believe me!, I certainly hope it does not. However, why jeopardize your chances of rescue? Ideally, emergency workers who may have to help you will have such aircraft-specific information.

Here's the valuable message:

MANUFACTURERS — These days nearly all producers use CAD software in their design. Making crash crew charts are thereby not a major burden. If you upload these charts to your company website, you can make airport managers aware of where to find them. Fellows like Keith Leonhardt may seek such material. Others will not be so vigilant but at least you'll have them available if a first responder organization contacts your company. The Imperative — Not only are you potentially helping a customer get rescued with greater success but you will have one more line of defense if a lawsuit occurs. I hope neither happens, but if you sell enough airplanes, it becomes increasingly likely.

PILOTS / OWNERS — Encourage your manufacturer to make such crash crew charts available. It could be very important to your life. Well informed first responders can do their job faster and more effectively... and that could be the difference between life and not. The Imperative — If you find yourself in a situation as I once did, you may be very grateful that rescuers have the guidance they need to extricate you swiftly. Consider this as insurance (that is not very costly). You hope you never need it but may be so glad you arranged it ahead of time if the need arises.


Mainstream Media Awakens to Flying Cars
By Dan Johnson, July 11, 2016
Appearing in the Wall Street Journal's "Journal Report" section on July 11, 2016 is the Terrafugia TF-X. Find out more about this futuristic design at the company website.
Perhaps like many of you, I read the newspaper most mornings. Today I was reading the Wall Street Journal. In one of their special sections was an article about flying cars. As regular readers know, I try to keep up with this niche within our niche of aviation.

Major publication reporters are finally catching up with what we have been observing for several years. People talk about the "mainstream media" disdainfully for a reason. Even though they provide the "news," their realization of all things new is not necessarily that timely. So much is happening in so many fields that mainstream media reporters cannot be expected to keep up with all developments. A website like this one is laser-focused on Light-Sport Aircraft, light kit aircraft, and ultralights. Even a billion-dollar news organization can't stay up on the latest like we can.

In fact, today's "Journal Report" — a subsection of the daily newspaper — was all about aviation. The newspaper presented stories about flying cars, autonomous aircraft (that is, flown without human input), drones, and safety efforts by FAA. This was fun for an aviation nut like me; I am not accustomed to seeing aviation stories in a daily newspaper (well, unless an aircraft crashes... they're always all over that, of course).

When non-aviation writers write about aviation, I can easily see their errors, omissions, or plain old misunderstanding. They are writing about my area of expertise while for them it is one story in a day and they can only report what they've been told. Most have little or no direct knowledge.

One part of the flying cars story mentioned Google founder Larry Page's $100 million investment in Zee.aero, the very secretive company working on what I've speculated is an electric airtaxi.

Can you imagine how far $100 mill would go in the LSA, light kit, and ultralight industry? With a few exceptions (Icon comes to mind), that amount of dough is a substantial portion of — if not more than — what has been invested into the entire industry! Paige has also investing in another company called Kitty Hawk, reported WSJ writer Robert Wall.

Toyota May Be Thinking Differently about Aerocars
By Dan Johnson, July 5, 2016

Maybe you haven't heard enough about electric-powered aircraft, flying cars, and automobiles on autopilot (presuming you're aware of Tesla's fatal accident in May). How about a shape-shifting aerocar? Huh?! I know it sounds rather crazy but Toyota, being the world's largest car manufacturer, is not a name to be dismissed when they may choose to delve into the flying car business... twice, in a few months!

Nope, I'm not kidding. The Japanese car company was awarded a patent for a "Shape Morphing Fuselage for an Aerocar." The illustrations — typical patent artwork — might fool you. This is not some 1930s silliness. The U.S. Patent office published this very recently, on June 23rd, 2016.

Perhaps it's no more than a publicity generator, much like Amazon's drone delivery aircraft — about which, by the way, Amazon claims to be sincere. Or, maybe Toyota is afraid Terrafugia might beat them to an interesting market, something like Tesla did to the big boys of auto manufacturing. Maybe they're just trying to lock up some intellectual property. I wouldn't know the answer to those questions. I simply found a shape-shifting flying car to be intriguing.

Toyota's concept allows the wings to be stored within the interior while the car is on land unlike Terrafugia's Transition.
It is probable Toyota Aerocar inventors and Michigan residents, Umesh Gandhi and Taewoo Nam, know all about Terrafugia and their work on Transition. Toyota could not be seriously worried about a small start up when the multinational company has billions to spend. Nonetheless, they appear to be taking this well beyond Terrafugia's wing-folding Transition (though not beyond Terrafugia's much different approach with their Osprey-like, electric-powered TF-X).

Here's the general description appearing on their patent: "A shape morphing fuselage and method of transitioning an aerocar from a land mode to a flight mode. The fuselage includes... flexible frame member and tensile skin... as well as an actuation system configured to bend the frame members between a contracted configuration associated with flight mode and an expanded configuration association with land mode." All this is to allow collapsing the folding wings inside the vehicle for road travel. That makes sense but the Aerocar has to store this in space that cannot otherwise be used, rather like a hardtop convertible.

Terrafugia has demonstrated — and publicly flown, at Oshkosh and other locations — their Transition that folds its wings alongside the car body. This method can leave the wings exposed to road rash. Their TF-X design goes far beyond this and does not leave major flight components exposed but that's another story.

Another online outlet, England's Daily Mail, wrote, "Toyota believes flying has always been a dream central to the history of humanity and the car manufacturer may be getting closer to making it a reality." From my read of the patent, I cannot imagine this is particularly serious, but it might be a way to claim patent exclusivity on changeable car body shapes. For an outfit used to making millions of automobiles through several brands, an Aerocar could hardly seem particularly profitable.

When the operator is ready to fly, the wings can be extended generally from the sides of the shape morphing fuselage through a hatch.
Toyota's "tensile skin" could be constructed with an elastic or stretchy membrane material, like silicone, or a shape-memory material capable of expanding and contracting to smoothly wrap around the car's frame, according to language contained in the patent application.

So when the operator is ready to fly, the wings can be unfolded and extended — this part is much like Terrafugia's Transition — from the sides of the fuselage (Mssrs. Gandhi and Nam regularly referred to the Aerocar body as a "fuselage"). However, I see one big difference.

Transition's wings remain alongside the car where road debris could strike the wings. That always looked vulnerable to many observers. Toyota's shape-shifting Aerocar brings the wings inside. They can fit because the car body or fuselage can change shapes using actuators inside to twist and tug a tensile, or stretchy, skin. On the road with wings hidden, Aerocar looks something like a minivan. Aloft it becomes more streamlined.

The vehicle "would be driven using a power system that includes a battery pack, internal combustion engine, turbine, fuel cell, or other energy conversion device" driving a propeller or ducted fan. Motive power does not seem to be Toyota's main concern, partly as illustrated by the kludgy prop at the rear that would also have to be pulled inside... and the patent has no language about that.

The fuselage could employ a tensile body that stretches between flexible frame members that optimizes shape for flight versus ground operation.
Toyota engineers Gandhi and Nam dryly note that a vehicle designed with this futuristic morphing technology "can require physical trade-offs in design in order to facilitate operations in both the land mode and the flight mode," according to the patent published by the U.S. Patent and Trademark Office. Aerocar isn't designed with the passenger's comfort in mind, but is shaped to optimize aerodynamic lift, limit drag, and support flight stability.

So, is Toyota likely to enter the flying car business? Do they have a couple (or more) engineers working on things like Google's "Moonshot" group does, where the pay-off, if any, is years in the future? Maybe they are merely exploring ideas and filing patents as a way to show they're actually working on stuff and not wasting their days updating their Facebook pages. Again, I don't know. Yet when a multinational company with billions of dollars at their ready disposal cracks open the checkbook, it could lead to something interesting.

Toyota's shape-shifting design isn't the company's first flying car proposal. In September 2015, Toyota was awarded another patent for a vehicle that placed the wings under a compartment in the roof that would deploy at the touch of a button.

Maybe this is just an ongoing fascination with a George Jetson flying car that has tantalized humans for years. Then, again, who knows? Could a shape shifting Aerocar be in your future?

Jabiru Gets an “OK” from Australian CASA
By Dan Johnson, June 30, 2016

It doesn't often happen this way. When media reporters get hold of a story that casts a company or person in a bad light, this generates headlines. The results can be disastrous for that company or person. However, if the initial article turns out to be overstated, a followup report does not always earn publication. News organizations don't gain subscribers or advertisers by saying, "All is OK now."

Perhaps this was the situation with Jabiru... the engine side of the house, not the airframe side. As you can read in our earlier report, Jabiru was taken to task for some problems down under. You should judge for yourself.

"I hope people who read [CASA's] report get the main message that well-maintained Jabiru engines were not a problem but sloppy maintenance did them in," wrote Jabiru North America boss, Pete Krotje. "CASA does not mention the group of eight flight schools where most of the problems arose and that the same maintenance company did their maintenance." He ventured further saying, "I can't imagine that the FAA would take steps similar to CASA's limitations without knowing the source of the problem."

Pete wrote, "Limitations have been lifted on engines that have been maintained according to the Jabiru manual and have complied to the 'significant' Jabiru service bulletins & service letters." He expressed that, "It is a real round about way of saying that poor maintenance practices are the real cause of Jabiru engine malfunctions." Like it or not, aircraft — like houses, autos, RVs, boats, well... pretty much everything — require regular and proper maintenance. Fail in this mission and you invite problems.

Especially Pete liked this CASA statement: "The failures experienced can generally be attributed to the maintenance practices, not necessarily poor quality of maintenance but as discussed [in the report], any deviation from the current Jabiru recommendations does appear to introduce conditions that can rapidly deteriorate the engine health to the point of failure."

Jabiru Australia, the designer and manufacturer of their line of engines, wrote to owners of their equipment saying, "We have been notified that CASA will be replacing the [document] that expires on the 30th of June with a [document] that places no limitations on Jabiru powered aircraft compliant with maintenance procedures." They added, "It is heartening to see recognition by CASA of the issues faced which are beyond our control and the steps taken by Jabiru to deal with the issues within our control."

Jabiru in Australia was also pleased to see "the dramatic increase" in compliance to Service Bulletins, Service Letters, and maintenance procedures — which likely represents the good that came from CASA's investigation. Combined with their Jabiru engine training workshops, following these procedures has resulted in fewer incidents. Jabiru then insisted, "This puts us well ahead of Rotax for reliability, the standard by which CASA based their aggressive initial actions." Around the world, Rotax sets a high bar for reliability, and the Austrian company helps achieve this by rigorously encouraging mechanics to get initial and recurrent training.

All is not perfect, however. Jabiru Australia wrote, "It is disappointing, however, that CASA still retained an Acceptance of Risk Statement within the limitations for non-compliant aircraft as the signing of this provides no enhancement to the reliability of these engines and is still damaging to our business." The negative effect of a damning report can linger on long after the problem may have been solved.

Nonetheless, Jabiru Australia remained upbeat, concluding, "We will continue to work for and with our owners and operators to strengthen and grow the Jabiru Fleet.  We have weathered the storm; it is now onwards and upwards.

CASA produced an 11-page report on their conclusions which can be obtained by asking Jabiru North America.

In the report, CASA stated, "The Jabiru engine has been designed to be lightweight for Light-Sport applications and also to be easy and efficient to maintain. From the data provided, however, it appears that the engine is very reliant on a fastidious maintenance regime and is intolerant of variation to the schedule provided by the manufacturer." In other words, mechanics must follow the instructions of Jabiru.

CASA is aware that engines may not remain in the configuration as originally manufactured. Their report said, "It is understood that 'aftermarket' parts are available for experimental aircraft, and certain Jabiru engines may have been modified in ways that involve the installation of non-Jabiru manufactured parts. All of these modifications have the potential to contribute to the reliability of the engine, in a both a positive and negative manner." They concluded, "[We] recognize that a true and complete picture of reliability can only be achieved on the basis of a consider of known configurations."

The governmental agency finished with a series of specific recommendation that interested persons and Jabiru owners can find in the report, called "Jabiru Engine Reliability Analysis."


Summertime Float Flying; Now You Can Afford It
By Dan Johnson, June 28, 2016

Merlin PSA recently took its first flight on Aeromarine 800 amphibious floats. all photos courtesy Aeromarine LSA
It's summer. It's hot. The water beckons. Yet, you're a pilot. How do you enjoy both? Get a seaplane, preferably a Light-Sport or light kit seaplane. You have several choices. The trouble is that any seaplane is priced well above landplanes of similar configuration. Some LSA seaplanes smash through the $200,000 barrier. That may represent a fair value for what you get but it exceeds the budget of many recreational pilots. How about $55,000 to $65,000? That sounds better, doesn't it?

Runway testing and cross country trials of the float-equipped Merlin PSA is complete. Aeromarine LSA owner Chip Erwin reports performing stalls, turns, climb, and cruise tests, each of which passed his criteria, although he continues in trials. The floatplane Merlin has not yet entered the water but that will happen in days after Chip finishes his initial wringing out of the float version. These floats are amphibious so land trials made sense at first.

Chip reports, "I have been using the 1730 millimeter (68 inch) DUC Hélices Flash prop because theoretically it is better for acceleration and climb which is nice to have on a seaplane." He reported good results with about a 900 foot per minute climb rate and cruise at 85-92 mph.

Yet cruise was definably better with the smaller (1660 mm / 65 inch) prop so Chip noted, "From a business perspective I really only need to offer that prop." He added that it works fine on floats or wheels and that makes inventory stocking easier. "Using the 1660 mm prop set for cruise pitch I saw 100 mph TAS at only 2,000 feet, with floats!" Given Merlin PSA's roomy solo cockpit that includes baggage space, hitting 100 mph on floats qualifies as good performance. Even backed off to 5500 rpm for better economy, speed was 96 mph TAS and 91 mph indicated, Chip reported. That's a fair pace given he plans to fly from central Florida to Oshkosh for AirVenture 2016.

Longtime light aviation entrepreneur, Chip Erwin (the original developer of the popular SportCruiser) knows a thing or two about floats. Besides developing several airplanes — one of which was a pioneering LSA seaplane called Mermaid — his then-Czech-based company also developed aluminum floats.

Chip identifies three ingredients that make for a good floatplane: (1) plenty of wing area, perhaps explaining why the Brazilian Super Petrel flies well as a biplane seaplane; (2) plenty of horsepower, clarifying why many LSA seaplane designers flocked to Rotax's new 915 that will provide 135 horsepower when ready; and, (3) big floats, which might explain why a set of Aerocet floats for a CubCrafters cost more than $50,000... only for the floats and related gear.

Merlin PSA on floats is a single seater. I'll come back to that but it makes clear why Merlin's wings qualify as big. You might not think a 65-horsepower Rotax 582 represents a lot of power but for a light single seater, it most certainly is. The wheeled version is a very lively performer. Finally, Merlin's floats support 800 pounds, each!, illustrating why a pair of them sit so high in the water. Get all Merlin specs.

What may be more surprising is that the choice of a single seater makes Merlin hit all Chip's points: its wing is large; power is high for its weight; and the floats have minimum draft... all of which make this new light kit a solid performer.

Nonetheless, I can hear your lament, "But it's only a single seater." Let me observe two things: First, most airplanes with two or even four seats are most commonly flown solo. Years of surveying told AOPA that the average occupancy of a typical (four seat) GA plane was 1.6, suggesting that overwhelmingly these aircraft are flown with only the pilot on board. Secondly, most seaplanes are flown solo. Chip likes to joke," You can spend $100,000 more than Merlin but that's a lot of money for your cellphone holder... the empty seat next to you. Seriously, think about it. How many times do you truthfully fill both or all your seats?

If you have to take someone or the whole family aloft, go rent a Cessna 172 somewhere. They are common and if you have a medical, problem solved. For all the times when you fly solo, Merlin will offer a dashing example, and one that saves you a bundle. Sold in kit form, you can start with a wheeled Merlin and basic equipment, getting aloft for $28,000 powered by the Rotax 582.

"Alright," you say, "but what if I just don't like two stroke engines?" Even if you don't accept that Rotax has sold tens of thousands of these engines that have been proven reliable in millions of hours of flying, Aeromarine LSA has a four stroke Merlin in late stages of development. By fall 2016, you should also be able to choose the HKS for about $3,000 additional. It may offer slightly less climb than the Rotax 582, but it should cruise at a similar speed and will burn half the fuel. In reality, though, many readers of this website know the Rotax 582 is as bulletproof as a two stroke gets, and the price is right. So is the nationwide, indeed worldwide, support.

As he knows floats and fitting them to various airplanes better than many aviation business owners, I asked for more float tips. Chip identified three guidelines.

The first was the pattern of a more wing area, plenty of power, and large enough floats. The second point is that floats tend to cost about 20% of climb and cruise performance and, of course, this factors in to how long it runs on water before launching; less time is always better because floatplanes can take a pounding on some water surfaces. That's why you always hear seaplane people discussing the number of seconds before they leave the surface. The third point is that, in general, you don't lose payload by adding floats. That sounds counterintuitive given the weight of floats and amphib gear, but Chip maintains that, "The floats lift themselves, using shape and angle of attack." Because seaplanes fly a bit slower, they can also tolerate turbulence reasonably well.

You can catch the video below to see — via text lines added in editing — facts about how long Merlin remains on the ground, on hard surface or turf, plus other parameters.

However, I come back to that old saw about what is the essential ingredient to make flight possible: money! Merlin PSA on floats — even equipped with BRS parachute, TruTrak ECO autopilot, ADS-B out transponder, amphibious gear, and all the features you'd expect on most recreational aircraft — will list at just $65,000. Given that is less than we expected a dozen years ago for most Light-Sport Aircraft, on wheels!, that is a definite bargain. Yes, you have to build it; it's a kit. However, the $65K price tag is for the quick-build model including builder assistance in central Florida (not far from Disney so the family can amuse themselves while you pull rivets). In a couple, three weeks you'll be close to done and that isn't bad for an airplane bound to put a smile on your face.


* Another modestly priced seaplane kit, the Aventura series, is available from Aero Adventure.
