Airworthiness Directives; Airbus Model A330-200 and -300 Series Airplanes; and Model A340-200 and -300 Series Airplanes

The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A330-200 and A330-300 series airplanes; and Model A340-200 and -300 series airplanes. This AD requires repetitive detailed inspections for discrepancies of the inboard and outboard actuator fittings of the aileron servo controls, corrective actions if necessary, and eventual replacement of all the attachment bolts of the aileron servo controls. This AD results from several cases of bushing migration on the inboard and outboard actuator fittings of the aileron servo controls; in one case the bushing had migrated completely out of the actuator fitting and the fitting was cracked. We are issuing this AD to prevent rupture of the inboard and outboard actuator fittings of the aileron servo controls, which could result in airframe vibration and consequent reduced structural integrity of the airplane.
