Plain English Summary

1/10 complexity

This is an Airworthiness Directive (AD) — a mandatory safety rule issued by the Civil Aviation Safety Authority (CASA) under aviation law.

What it does: Requires owners and operators of Piper PA-25 Pawnee aircraft (all models) to inspect the exhaust system regularly to ensure it is safe.

Key requirements:

Who is affected: Anyone operating a Piper PA-25 series aeroplane.
What must be done: Inspect the exhaust system following the procedures in Piper Service Letter No. 324C (the manufacturer's technical instructions).
When: Every 100 hours of "time in service" (flight time) starting from 28 February 1974.

Why it matters: Airworthiness Directives are legally binding. An aircraft cannot fly legally unless it complies with all applicable ADs. This rule ensures exhaust system failures — which could cause carbon monoxide leaks or fires — are caught before they become dangerous.
