AD/PA-25/19 - Engine Mount - Inspection - CANCELLED

What this does: This document officially cancels a previous aviation safety rule (Airworthiness Directive AD/PA-25/19) that forced owners of Piper PA-25 Pawnee aircraft to perform regular dye-penetrant inspections on engine mounts.

Who it affects: Owners and operators of Piper PA-25 (Pawnee) series aeroplanes — typically agricultural spray planes and glider tugs.

What it means:

• The previous requirement for engine mount inspections every 250 flight hours is no longer legally mandatory.
• The Civil Aviation Safety Authority decided this specific inspection no longer warranted a compulsory Directive (though operators can still do it voluntarily as part of normal maintenance).
• This removes a regulatory burden unique to Australian operators of these aircraft.
