Plain English Summary

1/10 complexity

This mandatory Airworthiness Directive requires operators of Schweizer/Hughes helicopters (models 269A, 269A‑1, 269B, and 269C with serials before 1274) to inspect the collective pitch mixer bellcrank per Schweizer Service Information Notice No. N204 and replace any incorrect part before further flight. Compliance is due by the next scheduled maintenance after 31 Oct 1987 or before installing the component after that date. It addresses a safety risk from incorrect bellcranks that can impair collective control.
