Lycoming crankshafts

Yes. Not to mention continuing to sell cylinders made of tempered cottage
cheese and denying there's a problem.

It sure gives me a lot of faith in certified aircraft engines. Not.

If another company were to step up with a new technology engine, with
replacement STC's for most all of the popular spam cans, they would clean
house.

We can only hope. The obstacles are enormous.

I don't know about anyone else, but Lycoming's latest dirty trick with the
crankshafts sure would leave a bad taste in my mouth, if I owned one. I
would not want to consider any purchase with a Lycoming in it.

What good is part tracing, ore to finished part? I thought that was meant
to protect from these kind of problems occurring?

I would think a class action law suite would sure be in order, for all of
the people it must involve.

Drive yet another nail in the coffin of GA. :-((

Indeed.

Speaking of that, did you see DeltaHawk is saying 18 months for release
to
the public? How long have they been saying that? Years? Decades?

As long as they say 18 months to release they are covered forever. :-)

Let's see if we can't squeeze three threads out of today's AvWeb. :-)

Delta Hawk diesel engines

The American Diesel, Still Struggling For Air

"DeltaHawk, a small company based in Racine, Wis., has been working for
about a decade to develop a diesel engine for GA aircraft -- the only such
engines being built in the U.S., the company says. The engine first flew
back in May 2003 in a Velocity RG, and since then has been making the rounds
of trade shows as R&D continues. A few of the 200-hp engines have been built
for experimental aircraft, but the company says it is still at least 18
months away from having an FAA-certified engine, and money problems are
slowing down the process. With a little luck, the company hopes to sell more
than 3,600 of the engines in 2010. The company will be exhibiting its
technology at Sun 'n Fun, coming up in Lakeland, Fla., April 4-10."

Kurt Manufacturing will be machining the components for DeltaHawk. KM is
down the road from me, maybe five miles.

I'm not sure that this should effect your faith in certified engines. I
don't believe Lycoming ever had a crankshaft failure. This seems like a
bunch of CYA to me.

Unfortunately, people make parts and people are not perfect.
All the companies buy parts from suppliers. Rarely a
suppliers of parts knowingly uses weak materials or skips
some step to manufacture. Some times a part is not designed
properly and sometimes there is a error such as not using
the proper radius on a machine flanged.
Lycoming and Continental build engines and buy parts.
Everything gets inspected, all the paperwork is checked, but
stuff happens.
Any manufacturer who designs and certifies a new engine will
have the same sort of problems, plus the technology will be
new and untried, so there may be problems that are
unexpected.

Some companies have a better handle on ALL facets of the manufacturing
process than other companies. Corporate culture?

Some industries adapt to new quality standards better than other industries.

Survival is often a brutal thing to watch.

I watched my corner of the brewing industry go from the 1970's to the
1990's, inside of 5 years. It wasn't fun but we did it. We survived ...for a
few extra years, anyway. Ten.

Rather like GAMI stating on their web site, regarding their PRISM
electronic ignition, "FAA STC certification expected soon". That page hasn't
really changed in four years.

Ya got to be kidding me... There are a couple of dozen flyers dead
already resulting from their " CERTIFIED", overpriced, traceable, FAA
approved cranks.
