Plain English Summary

2/10 complexity

What this is: A mandatory safety order (called an Airworthiness Directive or AD) issued by the Civil Aviation Safety Authority (CASA) under the Civil Aviation Regulations.

What it requires: Owners or operators of Maule M-4 aeroplanes (specifically those with serial numbers 4 through 91) must have the engine mount (the structure that holds the engine to the aircraft body) inspected and modified according to instructions in Maule Service Letter No. 20.

Why it matters: This prevents potential structural failure of the engine mount, which could cause the engine to detach from the aircraft during flight.

Who must comply: Anyone operating the specified Maule M-4 models (S/Nos. 4–91).

Deadline: The work must be completed within 100 hours of flight time after 31 October 1978.
