AD/PA-23/32 Amdt 2 - Cabin Door Latch - Modification - CANCELLED

This document cancels an outdated aviation safety rule about door locks on specific Piper aircraft.

What this is: An Airworthiness Directive (AD) — a mandatory safety instruction issued by the Civil Aviation Safety Authority (CASA) that has the force of law for aircraft owners and operators.

What it does: It formally cancels a previous directive from 1967 that required owners to modify the internal auxiliary door lock on Piper PA-23 Apache and Aztec aeroplanes.

Why it matters: The original safety modification was required over 40 years ago. By 2008, all affected aircraft would have already been modified, making the old rule unnecessary. This cancellation removes redundant paperwork and compliance obligations for aircraft owners, maintenance organisations, and pilots.
