Plain English Summary

1/10 complexity

What this does: This document officially cancels (revokes) a previous aviation safety requirement for certain Piper aircraft.

Who it affects: Owners and operators of Piper PA-24 (Comanche) series aeroplanes who were previously required to modify their automatic pilot systems.

The backstory: The original rule (AD/PA-24/34) required installation of a shear pin in the automatic pilot's roll servo — a safety device to prevent damage — following specific manufacturer instructions (Piper SL No. 695 or Edo-Aire Mitchell SL ML38). Owners had to complete this within 200 hours of flight time after September 1974.

What changes now: As of 23 October 2008, this modification is no longer mandatory. The safety requirement has been removed because it is no longer considered necessary.
