AD/PA-46/7 - Oxygen System Electrical Wiring Rerouting - CANCELLED

What this does: This document officially scraps an old aircraft safety rule (called an Airworthiness Directive) that required owners of specific Piper aeroplanes to modify their oxygen system wiring.

Who it affects: Owners and operators of Piper PA-46 (Malibu) series aeroplanes registered in Australia.

The backstory: Back in 1984, the aviation safety regulator mandated that these planes needed their oxygen system electrical wiring re-routed to prevent potential hazards. Owners had to complete this within 100 flying hours after December 1984, following the manufacturer's guidelines (Piper Service Bulletin 791).

Why it matters: As of 9 April 2009, this specific maintenance requirement is officially dead. If you own one of these aircraft, you no longer need to perform this particular wiring modification to stay compliant with this rule (though all other safety regulations still apply). It’s essentially housekeeping—removing an outdated technical requirement that is no longer considered necessary for safety.
