AD/PA-32/36 - Fuel Valve - Replacement - CANCELLED

This document cancels a previous aircraft maintenance requirement.

Specifically, it removes a rule that required owners and operators of Piper PA-32 (Cherokee Six) series aeroplanes to replace the fuel valve assembly.

Who is affected:

• Owners and operators of Piper PA-32 (Cherokee Six) aircraft
• Licensed aircraft maintenance engineers
• Aviation businesses operating these aircraft

What changed: The original directive mandated fuel valve replacement in accordance with Piper Service Bulletin No. 444. This cancellation eliminates that requirement entirely, meaning affected aircraft no longer need to undergo this specific modification to comply with this directive.

Why it matters: This reduces maintenance costs and downtime for operators of these aircraft, while indicating that the safety concern prompting the original valve replacement requirement is no longer considered a critical risk (or has been addressed through alternative means).
