'John,
First, I check for compliance with the recurring wing
and center section AD's. Basically I look at general
condition, looking for any deterioration, especially
in the low areas of the wings. A wing will pick up
moisture at the access panel to the aileron bellcrank.
Look for any deterioration, delamination or
discoloration of the plywood spar face. I also tap
the spar with a very light ball peen hammer to check
for any separation of the plywood skin that is glued
to the spar. I also look at the contition of the
aileron and flap wells. That's about it. The best
way to keep a PT wing in shape is to keep the airplane
clean and don't leave them outside for a long period
of time. I once looked at a PT-26 that had sat on a
ramp for a year and a half. I buried half of my Swiss
Army knife blade into the underside of the right rear
wing spar! All the wood in the aircraft was bad from
exposure.
