Plain English Summary

2/10 complexity

This airworthiness directive mandates a physical modification to pilot and co‑pilot seats on certain Beechcraft King Air Model C90, E90, and F90 aircraft (specific serial ranges) to stop the shoulder harness from jamming against the seatback pan. Owners/operators must install the change per Beechcraft Service Instruction No. 1176 within 100 hours time‑in‑service after 31 July 1981. It prevents slacked harnesses that could cause serious head or upper‑body injuries.
