Plain English Summary

2/10 complexity

This Airworthiness Directive (AD) is a mandatory safety order issued by the Civil Aviation Safety Authority for helicopter operators.

What it covers: All Schweizer (Hughes) model 269 helicopters.

The safety issue: Throttle and governor control cables manufactured by Cablecraft may have manufacturing defects, wear, or handling damage. If these cables malfunction, pilots could lose control of engine power settings, creating a serious flight safety risk.

What operators must do:

Part 1 (One-time action): Within 100 hours of flying time after 30 June 1986, inspect and remedy the cables according to Schweizer Service Information No. N196. Any spare cables must be checked before installation.
Part 2 (Recurring action): After the initial inspection, repeat the check every 100 hours of flying time.

Why this matters: This prevents potential engine control failures that could cause power loss or uncommanded power changes during flight, reducing the risk of accidents.
