Summary
We propose to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A318 and A319 series 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 that cracks were detected on frame (FR) 16 and FR 20 web holes and passenger door intercostal fitting holes at the door stop fitting locations. This proposed AD would require repetitive rototest inspections of the holes at the door stop fittings for any cracking, and corrective actions if necessary, as specified in an European Aviation Safety Agency (EASA) AD, which will be incorporated by reference. We are proposing this AD to address the unsafe condition on these products.
