AD/PA-42/4 Amdt 1 - Main Landing Gear Pivot Shaft Assembly Bolts - CANCELLED

This instrument cancels a previous aviation safety rule affecting specific aircraft.

What it does This document officially cancels Airworthiness Directive (AD) AD/PA-42/4. That directive previously required owners and operators of Piper PA-42 Cheyenne III aircraft to inspect or replace the main landing gear pivot shaft assembly bolts within a specified timeframe.

Who it affects Owners and operators of Piper PA-42 Cheyenne III series aeroplanes.

Why it matters The cancellation removes the mandatory inspection requirement for these specific landing gear bolts. This typically occurs when the safety risk has been addressed through other means—such as manufacturer service bulletins, fleet modifications, or the issue being covered by a different safety directive—meaning the original rule is no longer necessary.
