Plain English Summary

1/10 complexity

This document cancels a previous aircraft safety rule that forced owners of certain Piper planes to inspect their wing rear spars every year.

Who this affects: Owners and operators of Piper PA-23 Apache and Aztec series aircraft.

What changes:

You are no longer required to perform the annual inspection of the wing rear spar and its attachments.
This removes the maintenance obligation previously mandated under Australian Airworthiness Directive AD/PA-23/59.

Why it matters: The Civil Aviation Safety Authority (CASA) cancelled this requirement because safety data showed no service difficulties or defects with these wing spars. When a safety rule is no longer justified by actual risk, it gets removed to reduce unnecessary compliance costs for aircraft owners.
