Plain English Summary

2/10 complexity

Owners/operators of specified Piper PA‑24 series aeroplanes must inspect the aileron nose rib every 100 hours (starting within 100 hours after 30 Nov 1979) until Piper Kit Part No. 763 893 is fitted, which removes the recurring inspection. The measure responds to reported rib cracking, shifts costs and work onto owners (recurring inspections versus one‑time kit installation), and refers to Piper Service Letter No. 850 or FAA AD 79‑20‑10 for procedures.
