Plain English Summary

2/10 complexity

This AD requires operators of Schweizer (Hughes) 269A/A‑1/B/C helicopters delivered before 1 August 1970 to inspect specific main rotor lead–lag and flapping hinge bolts (P/N HS1446‑10‑68, Vendo ID BM). Compliance must follow the referenced Hughes SIN N‑78 or FAA AD 70‑17‑3. It shifts inspection and corrective‑action responsibility—and related costs and downtime—to aircraft owners/operators to address potential safety risks.
