AD/PA-31/77 Amdt 1 - Fuel Crossfeed Valve - Inspection - CANCELLED

What this does: This document cancels a previous aviation safety rule that required owners of Piper PA-31 aircraft to inspect their fuel crossfeed valves.

Who it affects: Owners and operators of Piper PA-31 series aeroplanes (twin-engine aircraft).

Why it matters: The original directive mandated a one-time inspection of the fuel crossfeed valve (a component that lets fuel flow between tanks) according to manufacturer guidelines. This cancellation removes that requirement entirely because all affected aircraft have already been inspected. Operators no longer need to perform this check or maintain records proving compliance with the old rule.
