Dennis...

I must say that I'm beginnging to enjoy our little give and take here.
Herein lies more "on sale" wisdom. NO MILITARY or EX-MILITARY aircraft
parts are certified for use on civilian aircraft. The reason being that
military aircraft fly beyond the allowable civilian flight dynamics
envelope. That means that they operate in mission profiles that exceed
flight manual and certification limits published in FAA Approved flight
manuals and Type Certificate Data sheets for similar CIVILIAN aircraft.
Some of these do make for interesting conversation pieces as wall hangings
or things like lamps in a civilian market. Once upon a time here in New York
there was a radio raffic reporter named Jane Dornacker. She and her pilot
crashed into the Hudson River during a broadcast traffic report. I just
happened to be listening to WNBC at that precise time. Jane Dornacker was
killed.. Subsequent investigation revealed that the Enstrom helicopter they
were flying in had an ex-military clutch installed which happened to fail
causing loss of power to the rotor. Do a GOOGLE search on her name and you
will eventually find the story. I hope that others in this forum may also
benefit by some of the things that I tell you, because whatever I tell you,
YOU CAN TAKE IT TO THE BANK.
