Cessna is currently using their ability to write Service Bulletins and to
request a companion Airworthiness Directive to essentially ground all the 400
series Cessna twin engine aircraft due to supposed flaws in the wing spars.
This is similar to the Bulletin and AD route that Beechcraft used to attempt to
put the T-34 Mentor out of the sky. They don't have to lobby anyone.


If this was truly Cessna and Beech's intention, wouldn't it have
been easier to just quit making parts? The amount of work to PMA
every part on the aircraft makes it unlikely anyone else would step up
to support them.

In the case of the T-34, I think the spar AD was warranted. They
were actually snapping in aerobatic flight.
