Plain English Summary

2/10 complexity

This Airworthiness Directive requires owners and operators of Pilatus Britten‑Norman BN‑2 Islander aircraft to permanently retire the wings and fuselage frames before the airframe reaches 28,000 total flight hours to prevent metal‑fatigue failure. It applies to all BN‑2 models, extends a prior deadline based on related Trislander testing, and is an interim measure pending a full manufacturer fatigue review.
