Plain English Summary

2/10 complexity

This directive mandates a safety modification for specific Piper aircraft to prevent engine failure from water contamination.

What it requires: Owners of Piper PA-23-250 aircraft fitted with Met-Co-Aire wing tip tanks must install an additional water drain valve in each wing tip fuel tank.

Why it matters: Water can collect in aircraft fuel tanks and cause engine failure. The extra drain valve provides a way to remove this water during pre-flight checks.

How to comply: Install the valve following a plan approved by the Secretary (the aviation safety regulator). Using Engineering Order No. JBA/1 from Jack Brabham Aviation Pty. Ltd. is explicitly approved as meeting this requirement.

Who is affected: Operators of the specific aircraft model and configuration mentioned.

Compliance timeframe: Within 100 hours of flight time after 30 June 1972.
