Airworthiness Directives; Airbus Model A320-111, -211, and -231 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A320-111, -211, and -231 series airplanes, that requires repetitive inspections to detect missing or cracked bolts and fittings of the frame-to-pressure-floor connection; and corrective actions, if necessary. This amendment also provides for optional terminating action for the repetitive inspections of the affected fittings. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to detect and correct fatigue cracking in the bolts and fittings of the frame-to- pressure-floor connection, which could result in reduced structural integrity of the airplane.
