Plain English Summary

2/10 complexity

This airworthiness directive mandates a safety fix for Bushby Mustang II aircraft to prevent the cockpit canopy from detaching in flight.

What must be done:

Reinforce the canopy framework at the rear (aft) corners
Manufacture and install a new retaining pin and bracket at the rear of the canopy

Why it matters: Following a fatal accident where a canopy detached mid-flight, these modifications are required to ensure the canopy stays securely latched and structurally sound.

How to comply: Owners must carry out the work according to the technical specifications in the Mustang II Canopy Frame Revision Instruction dated 11 January 1984 (available from Department of Aviation Regional Offices). The modification had to be completed before 31 August 1985.

This applies to all models of the Bushby Mustang II series.
