Plain English Summary

3/10 complexity

This mandatory Airworthiness Directive requires operators of Short SC7 (Skyvan) aircraft listed in Short Alert SB No. 27‑A64, Rev. 4 to inspect—and if necessary modify—the wing centre‑section support structure for the flap mechanism to address in‑service cracking. Compliance is required within 50 hours time‑in‑service after 2 October 1979. It directly affects aircraft operators (who bear costs and downtime) and delegates technical detail to the referenced Alert Service Bulletin.
