Cessna C337 SID

[K337A]

C337 SID ?

Is there a public database of documented failure/failed inspections of C337 spars? I have the 5000 hr. AD. on my desk and have wondered about the failure rate of this inspection and the incidents which required it. What has caused this at this time? I have checked the NTSB database the best I could and the incidents of Spar problems causing a accident beside repeated aerobatic flight is non existent. It would be good science to be able to compare failure rates with other aircraft in a logical process. God help the GA owner if the FAA Legal Department has chosen this avenue to demonstrate their authority to the lowly taxpayer/owner.
