Airbus Model A319, A320, and A321 Series Airplanes
Model A319, A320, and A321 series airplanes; all serial numbers having received Airbus Modification 20234 (Airbus Service Bulletin A320-25-1055) (installation of telescopic girt bar for slide raft), but NOT having received Airbus Modification 28212 (Airbus Service Bulletin A320-52-1102, Revision 01, dated November 25, 1999); certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A319, A320, and A321 series airplanes, that requires replacement of the trigger spring of the slide bar on each of the passenger doors with a new, stronger trigger spring. This action is necessary to prevent corrosion of the trigger spring on the slide bar of the passenger doors, which could result in incorrect locking of the slide bar and, during deployment of the escape slide, lead to a delay in evacuating passengers in an emergency. This action is intended to address the identified unsafe condition.
