Does the recent engine mount / crankshaft failure AD cover Lycoming TIO-540's
in Lancairs?  If so, what is the response?  Are the Lycoming TIO-540 Lancair
IV's grounded?

On a second note, how does this compare with the Continental crank AD of two
years ago?

For the uninformed, ALL (repeat ALL) 300+ HP turbo Lycomings have been
grounded for crank and/or mount failures after two fatal accidents.  After
all the vitriol leveled by the Lyc crowd at the Con supporters over the last
two years, it should be interesting to see how the shoe fits the other foot.

A final question.  What would the market acceptance be for Jet A powerplants
that achieve demonstrated reliability (all the way to TBO at rated power plus
meeting FAA cert requirements), lower fuel burn, and lower cost than the
current Lyc-Con offerings?  This is asked from the perspective that only
AFTER such things are proven would the question be valid.  Selling this
before it is proven is not in the cards.
