Plain English Summary

1/10 complexity

This Airworthiness Directive (AD) mandates a safety inspection of bolts on the engine cooling impeller for specific Schweizer (Hughes) 269 series helicopters.

Who it affects: Owners and operators of:

Model 269A (serial numbers 0011–0314)
Model 269A-1 (serial numbers 0001–0041)
Model 269B (serial numbers 0001 onwards)
Model 269C (serial numbers 0004–0389)

What must be done: Operators must inspect the bolts on the engine cooling impeller according to Hughes Service Information Notice (SIN) No. N-122.

When: Within 100 hours of flight time after 31 March 1975.

Why it matters: This directive prevents potential engine failure due to loose or faulty cooling impeller bolts, ensuring the helicopter remains safe to fly. Operating without completing this inspection renders the aircraft not legally airworthy.
