Summary
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A318, A319, A320, and A321 series airplanes. This proposed AD was prompted by reports of low halon concentration in the forward and aft cargo compartments due to air leakage through cargo door seals, and the certification of improved cargo door seals. This proposed AD would require replacing the forward, aft, and bulk cargo compartment door seals with new seals; and installing a placard on the forward, aft, and cargo compartment doors; and for certain airplanes, implementing an operational limitation for certain routes, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
