Airworthiness Directives; Airbus Model A340 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A340 series airplanes. This action requires a one-time inspection of all gland nuts supplied with certain shock struts of the center landing gear (CLG) to verify that the gland nuts have the correct thread profile, and replacement of any defective gland nut with a new gland nut. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified in this AD are intended to prevent the failure of the CLG, and subsequent damage to the airplane structure or injury to airplane occupants.
