I did one wing removal and inspection back in the period of applicability of the AD. It was a laborious task. I suspect that we may see a reissue of this service letter.
The bigger problem for Piper owners, should this service letter be made applicable again, will be what happens to your legacy Piper should a defect be found. With some experience with the issue, I'd be concerned about the availability of replacement parts (let alone the cost to install a new spar into an older Cherokee wing).
That AD makes for very interesting reading. Essentially suggesting this kind of fatigue would normally only be found on aircraft with more than 5000 hrs on the airframe, significant damage history and operating in 'severe' environments.
