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 to detect corrosion, cracking, or rupture of the support arms of the aileron balance weights; and repair, if necessary. Accomplishment of the repair terminates the repetitive inspection requirement of this AD. 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 corrosion, cracking, or rupture of the support arms of the aileron balance weights, which may cause reduced flutter damping or jamming of the aileron, and consequent reduced controllability of the airplane.
