Airworthiness Directives; Airbus Model A321-111, -112, and -131 Series Airplanes

This amendment supersedes an existing airworthiness directive (AD); applicable to certain Airbus Model A321-111, -112, and -131 series airplanes; that currently requires repetitive inspections to detect fatigue cracking in the area surrounding certain attachment holes of the forward pintle fittings of the main landing gear (MLG) and the actuating cylinder anchorage fittings on the inner rear spar; and repair, if necessary. The existing AD also provides for optional terminating action for the repetitive inspections. This amendment revises the inspection threshold and repetitive intervals for the currently required repetitive inspections. The actions specified in this AD are intended to detect and correct fatigue cracking on the inner rear spar of the wings, which could result in reduced structural integrity of the airplane. This action is intended to address the identified unsafe condition.
