Airworthiness Directives; Aerospatiale Model SN-601 (Corvette) Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to all Aerospatiale Model SN-601 (Corvette) series airplanes, that requires repetitive inspections, and repair if necessary, of the locking indication system of the drag strut jack on the main landing gear (MLG) to detect corrosion and damage resulting from its operation. This proposal also requires replacement of seals and backup rings with new parts. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent failure of the locking indication system of the drag strut jack on the MLG due to corrosion. Such corrosion could prevent the MLG from locking and result in the subsequent collapse of the MLG.
