Airworthiness Directives; Short Brothers PLC Model SD3-30, SD3- 60, and SD3-SHERPA Series Airplanes
Traduction automatique locale · Langue originale de la source
Résumé
This amendment supersedes an existing airworthiness directive (AD), applicable to certain Short Brothers PLC Model SD3-30, SD3-60, and SD3-SHERPA series airplanes, that currently requires an inspection to detect corrosion on the distance piece associated with the wing strut pick up on the stub wing, and repair of corroded parts. This amendment requires repetitive inspections to detect corrosion of repaired or reworked distance pieces and adjacent side plates; and provides a terminating action for the repetitive inspections. This amendment is prompted by reports of corrosion on the distance pieces and adjacent side plates of the wing strut pick up. The actions specified by this AD are intended to prevent failure of the distance piece and adjacent side plates, which could result in reduced strength of the wing strut attachment to the stub wing on the fuselage and, subsequently, reduced structural strength of the main wing.
