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