Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A319-111, 112, -113, -114, -115, -131, - 132, and -133 airplanes; A320-211, -212, -214, -216, -231, -232, and - 233 airplanes; and A321-111, -112, -131, -211, -212, -213, -231, and - 232 airplanes. This proposed AD was prompted by a full-scale fatigue test that found cracks on the main landing gear (MLG) bay rear skin panel at the stringer run-out at Frame 46 and Stringer 32 on the left- hand and right-hand sides. This proposed AD would require repetitive special detailed inspections (SDIs) of the affected area for cracking and applicable corrective actions, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
