Plain English Summary

1/10 complexity

This instrument formally cancels a decades‑old Airworthiness Directive that required a one‑time structural reinforcement of the flap and stabiliser spars on 52 specific Piper PA‑23 (Apache/Aztec) aircraft.

Regulators consider the once‑only modification complete on affected aircraft, so the directive is now redundant; it affects owners/operators of those specific planes rather than the broader PA‑23 fleet.
