White Industries lists engines with flange runout. What does flange
runout tell about the engine?

It seems some prop strike engines have a larger flange runout reading
than others, and the larger the flange runout, the lower the price.
Why?

Thanks.

The run out will tell you how badly the flange is bent. Thats it. In
order to tell how much damaged there was you need to know several
things: What was the power setting when the engine had it's strike?,
What kind of prop?, What did it hit? Was it a sudden stop or a slow down?
Then you need to tear it down. Throw away the crank. have the case
throughly inspected, have all of the other moving parts throughly inspected.

Personally I would only buy one as a core exchange if the manufacturer
will take it.

It's only a service bulletin, not an AD.
Both Continental and Lycoming consider a teardown
mandatory after a prop strike.

no there is an AD note 2004 -10-14 i think that requires it

A few years back lycoming redefined what is a prop strike.....
A manufactururer SB does not make anything mandatory for a part 91
operator. An AD note does.......

Read the Lycoming AD/SB carefully. Just because you hit something does
not mean you have to do a tear down.

Michelle: I agree with your assessment. Nose gear failure with "power
off" with consequence of minor prop bend may not require a tear down.
Contact surface (scrape)on the prop will help determine what stresses
were on the crank per my mechanic.

Even if it were only and SB which is not "officially" mandatory, let's
say you have a prop strike. Every thing looks good, you replace or
straighten the prop and the thing runs well. Even the run out looks
good. About 50 or 100 hours later the crank lets go and you shred the
thing in an off field landing although no one gets hurt. What does
your insurance company say if they find out you have not complied with
that particular SB?

Will they pay and say nothing? Will they pay and complain? Will they
raise your rates? Will they let your renew at renewal time?

Who knows?

They will pay. Happened to a Cherokee around here and no questions were
asked.
