Airworthiness Directives; Airbus Model A320-111, -211, -212, and -231 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A320-111, -211, -212, and -231 series airplanes, that requires reinforcement of the tail section of the fuselage at frames 68 and 69. This amendment is prompted by reports indicating that the tail section has struck the runway during takeoffs and landings. The actions specified by this AD are intended to prevent structural damage to the tail section when it strikes the runway; that condition, if not detected, could result in depressurization of the fuselage during flight.
