FAA AD 2023–07–03

Requires cleaning and repetitively inspecting certain part-numbered left-hand fin spar caps, and repetitively inspecting the exterior of the fin skin and, depending on the results, accomplishing corrective action. This AD also prohibits certain corrective actions as a terminating action for the repetitive inspections unless the corrective actions have been approved as a terminating action, as specified in an EASA AD. This AD was prompted by a report of a fatigue crack in a left-hand fin spar cap.
