Summary
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A318, A319, A320, and A321 series airplanes. This proposed AD was prompted by a report that, during the assembly process, several gaps between the two parts of the girt bar fittings for the aft passenger doors were found to exceed tolerances. This proposed AD would require an inspection of the gap between the two parts of the girt bar fittings on left-hand (LH) and right-hand (RH) aft passenger doors, and corrective actions if necessary. We are proposing this AD to detect and correct incorrect gaps between the girt bar fittings. Detachment of a girt bar could lead to the separation of the slide or slide-raft from the fuselage, making the emergency exit inoperative, which could impede an emergency evacuation.
