Piper Aircraft Proposes New Airworthiness Directive for PA31 Models

Summary

The New Piper Aircraft, Inc. is proposing a new airworthiness directive to supersede AD 80-22-04, which requires inspecting the upper section of the FS 317.75 bulkhead for cracks and incorporating a reinforcement kit if any crack is found. The proposed action aims to prevent structural failure of the vertical fin forward spar caused by cracks in the FS 317.75 bulkhead.
