Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A319, A320, and A321 airplanes. This proposed AD would require installing spacer assemblies at the attachment points of the YZ-latches of the cargo loading system in the forward and aft cargo compartments, as applicable. This proposed AD results from tests that have shown that the attachment points of the YZ-latches of the cargo loading system fail under maximum loads. We are proposing this AD to prevent failure of the attachment points of the YZ-latches, which could result in unrestrained cargo causing damage to the fire protection system, hydraulic system, electrical wiring, or other equipment located in the forward and aft cargo compartments. This damage could adversely affect the continued safe flight of the airplane.
