Summary
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A318-111 and -112 airplanes, Model A319, A320, and A321 series airplanes. This proposed AD was prompted by reports of cracks on the forward corner fittings of engine pylon aft secondary structures. This proposed AD would require repetitive inspections of certain forward corner fittings of the pylon aft secondary structures, and corrective actions if necessary. This proposed AD also provides optional terminating action for the repetitive inspections. We are proposing this AD to detect and correct detachment of the lower fairing attachment and/or loss of the aft fixed fairing with the movable fairing from the airplane in flight, which could result in damage to the airplane.
