Plain English Summary

3/10 complexity

Operators of listed Mitsubishi MU-2 models must install manual ignition switches per the manufacturer service instructions and amend the Australian Flight Manual where fitted, or they may not operate the aircraft after 30 June 1987. Owners/operators bear the cost; the Civil Aviation Safety Authority mandates the specification. The AD’s safety aim is to ensure continuous ignition selection to prevent or rapidly recover from ice-induced engine flameouts, and it cross-references a related FAA directive.
