Plain English Summary

1/10 complexity

What this does: This document officially cancels a previous aviation safety rule (Airworthiness Directive AD/PA-22/15) that required owners of specific Piper aircraft to replace brake master cylinder diaphragms every 200 flight hours.

Who it affects: Owners and operators of Piper PA-22 (Tri-Pacer and Colt) series aeroplanes.

What changed:

Before: You legally had to replace these brake diaphragms every 200 hours of flying time.
Now: That requirement is scrapped (cancelled effective 25 September 2008).

Why it matters: CASA (the aviation safety regulator) decided this particular maintenance task wasn't actually necessary to keep these planes safe. This saves owners the hassle and expense of doing this specific brake work every 200 hours. The original rule wasn't even based on the manufacturer's instructions—it was unique to Australia—so they've ditched it.

In short: One less paperwork headache and maintenance bill for Tri-Pacer and Colt owners.
