AD/PA-36/4 - Flap Control - Modification - CANCELLED

This document cancels a previous aircraft safety rule (Airworthiness Directive) that required owners of Piper PA-36 Pawnee Brave aeroplanes to modify their flap control systems.

What it did previously:

• Required a one-time modification to the flap controls
• Had to be completed within 100 hours of flying time after January 1975
• Required following the manufacturer's Service Bulletin No. 439

What this document does:

• Cancels that requirement effective 12 March 2009
• Means owners no longer need to comply with the previous modification rule

This affects agricultural aircraft operators and owners of these specific Piper crop-duster planes.
