AD/PA-24/31 - Landing Gear and Flap Assemblies - Inspection - CANCELLED

What this is: This document cancels a previous aircraft safety rule (called an Airworthiness Directive or AD) that required owners of Piper PA-24 Comanche aeroplanes to inspect their landing gear and flap assemblies.

Who it affects: Owners and operators of Piper PA-24 (Comanche) series aircraft, and maintenance engineers who work on them.

What it does: It formally cancels the earlier directive (AD/PA-24/31) as of 23 October 2008. The original rule required a specific inspection within 100 flying hours after December 1973, following guidelines from the manufacturer (Piper Service Letter No. 650). Because that safety requirement is no longer necessary, this document makes it void—meaning owners no longer need to comply with that specific inspection rule.

Why it matters: It removes a regulatory burden from aircraft owners. Once cancelled, the specific inspection mandated back in 1973 is no longer legally required, though owners must still follow other current safety rules.
