Airworthiness Directives; Airbus Model A320 Series Airplanes

This amendment supersedes an existing airworthiness directive (AD), applicable to certain Airbus Model A320-111, -211, -212, and -231 series airplanes, that currently requires reinforcement of the tail section of the fuselage at frames 68 and 69. This amendment adds a requirement for reinforcement of the tail section of the fuselage at frames 65 to 67. This action also revises the applicability of the existing AD. 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, which could result in depressurization of the fuselage during flight.
