Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A318-111, -112, -121, and -122 airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes; Model A320-211, -212, -214, -216, -231, -232, and -233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. This proposed AD was prompted by reports of fatigue cracks on continuity fittings at the lower framing of the front windshield on airplanes on which a certain production modification has been embodied. Additional analysis showed that certain certification requirements for damage tolerance and fatigue are not met on airplanes in a certain post-production modification configuration. This proposed AD would require repetitive high frequency eddy current (HFEC) inspections of the central node windshield area for cracking, and applicable corrective actions if cracking is found, as specified in a European Union Aviation Safety Agency (EASA) AD,which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
