Plain English Summary

2/10 complexity

What this is: A mandatory safety inspection rule (called an Airworthiness Directive) for certain helicopters.

What it requires: Owners and operators of Hughes 369 series helicopters (including models made by McDonnell Douglas and Kawasaki) must inspect the bolts and nuts that connect the main rotor pitch links. This inspection must be done within 100 hours of flight time after 31 March 1977.

Who it affects: Anyone who owns, operates, or maintains Hughes 369 helicopters in Australia.

Why it matters: These bolts are critical for controlling the helicopter's main rotor. If they fail, the pilot could lose control of the aircraft. This rule ensures potential defects are found before they cause accidents.

Applies to: All models of the Hughes 369 series
Compliance deadline: Within 100 hours of flying time after 31 March 1977
