Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to all Airbus Model A319, A320, and A321 series airplanes. This proposal would require repetitive inspections for discrepancies of the lock bolt for the pintle pin on the main landing gear (MLG), and follow-on corrective actions, if necessary. This proposal is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by the proposed AD are intended to detect and correct a rotated, damaged, or missing lock bolt, which could result in disengagement of the pintle pin from the bearing, and consequent collapse of the MLG during landing.
