I have a 1964 336 and the AD is due at 5,000 TT.
My plane has not been flown in mountainous terrain.
I was looking for someone in the NJ, PA area who could
do the AD and appreciate your info that it should only
be a few hours of shop time assuming the spar caps
do not need replacement. You are right about 10,000 TT
for pressurized models of the 337's and 3,000 TT hrs for
planes flown in mountainous areas. Also I believe it
will be required every 500 Hrs also. If anyone knows
someone in my area who they could recomend to do
the AD please post it for me. Thanks Guys---its nice
to have someone out there to talk with and gather
info on my 336.
