Plain English Summary

2/10 complexity

What this does: Requires recurring safety inspections and modifications for the wing flaps on specific Piper aircraft.

Who it affects: Owners and operators of Piper PA-23-250 Apache and Aztec aeroplanes with serial numbers 27-1 to 27-451 inclusive, and 27-453 to 27-504.

What you must do: Inspect and modify the wing flaps in accordance with Piper Service Letter No. 363. You must perform this every 100 hours of flight time (called "time in service," meaning the time from when the engine starts for flight until it shuts down) starting from 25 May 1962. You must keep doing these checks until the modification is permanently installed.

Why it matters: This prevents mechanical failures in the wing flap system, which is essential for controlling the aircraft during takeoff and landing.
