I have been following another forum discussing the 1979 PA-32 wing spar and why it is not part of the proposed AD for Piper wing spars. From the information on the other forum, the 1979 PA-32 wing spar is different than earlier models and is the same as the Lance which has a higher GW (3,600 lbs). Everything that has been found so far points to the the same wing design except for the retractable landing gear. Is any one aware of the design difference and/or why the 1979 PA-32 did not get the increase in the GW? It would be interesting to understand why and if it is possible to get the GW increased.
