Virtual RV land:
It seems an Eggenfeller had a forced landing. The blurb pasted in at
the bottom is from Vans first flight web page.
My condolences to Roger Evenson, I really am sorry about what
happened. Please don't take offense at my opinions.
It breaks my heart to hear about these incidents. Anyone seriously
considering these engines needs to think long and hard about the
accident rate associated with these engines.
I helped a builder who had serious trouble keeping his CHT's down on a
garden variety lyc 360 RV-7. He was running nearly 450 F on climb
out. He made some changes and everything is in line now. This is a
well defined installation with step by step instructions but the
builder still had issues that could have led to failure.
I'm not being critical of this builder but my point is that even with
a well defined off the shelf installation there are many pitfalls that
you have to be careful of. With a completely new design there going
to be many lessons learned that will come out only when the design
sees actual service. In short the "right" way to run and install the
Subaru still is unknown, if it was then the guy at the bottom of this
message wouldn't be building another plane right now.
There are people that are well suited to establishing new designs and
there are people who want to fly blissfully planes places.
I know it is closed minded and counter to the mentality of most of us
experimental builders but I don't see the risk reward benefit in using
the Subaru engine compared to an IO-360 with electronic ignition.

With Darwin Barrie and Glenn Brasch flying chase in Darwin's RV7, the
first flight for 394RS occurred on 5/2/07 at KRYN, Tucson, Arizona.
This "farm tractor", a 9A (90534) was powered by a supercharged,
Eggenfellner EJ-25. First flight was a fabulous experience and a very
sweet ride. Many thanks to my wife Susie, bucking buddy Glenn, tech
counselor Gil Alexander, Charles Wilhite, Dan Watters and many others.
These things can't be built without lots of support.

With 50 hours on the Hobbs, and shortly after takeoff on 6/29/07, an
overboost (40" MAP) resulted in loss of engine power, and an
off-airport landing. Though the mains touched down on solid desert,
they soon encountered a mound of soft earth and a root which threw the
plane forward. A very quick nose-over followed. I thank the Lord (and
Van's design) for getting out with only a scratch. Charles' composite
canopy also did it's job, absorbing lots of energy. Now building a 7A
and looking forward to another first flight.

I agree that people installing alternate engines or propellers need
to have a realistic understanding of the increased risks they are
undertaking. But, if they really do understand those risks, it is a
bit presumpstious of us to try to tell them to install a Lycoming
instead. After all, the accident rate during the flight test phase
on RVs is quite a bit higher than the first 40 hours that a new owner
does in his Cessna. If we are really concerned about risk, why
aren't we all flying Cessnas?

All true Bill,
I spend about as much time trying to talk builders out of alternative engines (even the one I use) as I do helping them with advice on how to install them.
It's very amusing to read the various alternative engine company websites that talk about their proven reliability, numbers sold (total fiction usually) and how you can fly your loved ones with complete confidence when using their products. IMO, if you install an alternative engine in your airplane, you are a test pilot flying what truly is an experimental aircraft in every sense of the word.
I usually don't say this to builders who call me because I don't want them to think I'm insulting them but being on an open forum makes it easier.
FWIW, If you have to ask someone if you should put an alternative engine in your plane, you shouldn't.
If it's a good idea for you, you don't have to ask and no one could possibly talk you out of it.

Do they understand the risk or is it some infatuation with an auto
conversion and cheaper auto fuel? Was the RV-10 that crashed
with one fatality using an auto engine?
I will admit that I am biased against some things and one is auto
engines in aircraft. I won't fly in one or buy one.

My 2 pennies. YMMV
The cause of this accident would have been the same if it had occurred
on a turboed Lycosaur. The engine over boosted due to a failure of
something related to the turbo. What that was, I don't know ......
wastegate malfunction??? I don't know much about the specifics of the
Subaru turbo system so someone more knowledgeable than me will have to
cover that ground.
Indicting alternate engines just because of a system failure is like not
using tires on the car because they blow out sometimes.
Crap happens ..... I've had two Lycosaurs that let me down. Not one
'alternative engine' has done that. But having said all that, my -10
will have a IO-540 up front. Not because I'm down on alternative
engines ...... I just don't want to do all the work to put something
else up there.

I monitor the Eggenfelner E-mail list. He stated this accident happened right after a non Eggenfelener ignition and injection system was installed.

Answer: Risk versus Reward,....... We all think the Reward outweighs the
Risk,...not that there isn't any! Kinda like the stock market but we're

Whatever happened to the Honda piston A/C engine? I bet that if they were
to manufacture it, that they'd have lines of people at the door. Most would
be Lyco owners. I'd be one of the first.

Shoot me, but this whole auto conversion thing is still in the snake oil stage. Everyone wants something better than the lycoming and Continental offerings, and people tend to see what they want to see and ignore or minimize the rest. It is laudable that some want to be a part of developing the dream of a more modern, consistently reliable aircraft engine; but pretending that that engine is available today in the 120HP and up range is wishful thinking at best and approaches delusional at worst. So I say good luck and thank you to those doing the R+D with these engines, because someday due to your hard work and acceptance of the risk, we will all benefit. Just don't pretend that you are not participating in the R+D of an as yet unproven technology.

So does spaceship one, but I think anyone flying spaceship one realizes that his level of experimentation is a bit more than someone flying in a stock RV. I don't believe some builders (and their passengers) of planes with auto conversions have this same level of realization.

My guess is that if you are Honda's CEO, the market for piston aircraft engines looks smaller than what they make in motorcycle accessories. He wants the liability that goes along with aircraft for that!?

I have no issue with the highly subjective concept of “risk” when it comes to using automotive engines in experimental aircraft. My experience with an automotive powered aircraft, however, was not what I expected. I owned a Sonerai, (VW powered) and admittedly it was the least expensive dollar per hour plane I ever flew. I was not the original builder so I could not get a repairman’s certificate. Issue 1; I had a difficult time trying to find an A&P who would sign it off each year only because they weren’t “familiar” with anything not Cont or Lyc. The ones that would sign seemed more like rapists. Issue 2; Some insurance people I talked to back then didn’t want to hear about airplanes without “airplane” engines. Issue 3; When I eventually went to sell it I found I had a limited customer base because of Issues 1 and 2. Issue 4; A builder can save a chunk of money by using alternative power plants however “building” can be addictive and eventually you have to face the fact that some day you may want something “newer”, “faster”, etc and will be looking at selling. Odds are that what you saved in the beginning will be lost at sale due to Issues 1, 2, and 3.
� Considering the investment I now have in my Lyc RV-4 I prefer to have something I can liquidate quickly and equitably now that I am at an age where each class III (God forbid) may be my last.

Your right, Jim. No question (in my mind) that an RV powered by a alternative engine would have less resale value. However, keep in mind that there could be a $10,000- $20,000 cost difference in the engine cost alone - so, I would not expect to get as high a resale value (even if the alternative engine installation is perfect) as I simply do not have as much engine money in it.
I think more to the point might be the difficulty of selling it due to perception of risks, difficulty of acquiring insurance (I've had none, but others have), and perhaps not being able to find an A&E to sign off on the conditional inspections if you are not the original builder.
I think most if not all alternative engine enthusiasts are aware of these factors - resale value is simply not a major factor - the challenge of the project is probably what appeals to most.
