Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A318 series 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 a report of cracking found on the frame of the right- hand side sliding window in the flight deck. This proposed AD would require repetitive inspections for cracking of the vertical stiffeners of the left- and right-hand sides of the window frames and corrective actions if necessary, 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.
