Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A330 and A340-200 and -300 series airplanes. This proposed AD would require 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 proposed AD is prompted by 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 proposing 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.
