## Summary

This document revises an earlier proposed airworthiness directive (AD), applicable to certain Dornier Model 328-100 series airplanes, that would have required repetitive inspections to detect cracking of the support beam of the main landing gear (MLG) fairing; and permanent repair of any cracking found, which would terminate the repetitive inspections. This new action revises the proposed rule by adding a requirement for installation of reinforcement parts for the longitudinal beam of the MLG fairing, which also would terminate the repetitive inspections. This new action also limits the applicability of the proposed rule. This proposal is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this new proposed AD are intended to prevent cracking of the support beam of the MLG fairing, which could result in reduced structural integrity of the lower part of the MLG fairing, and consequent separation of part of the fairing from the airplane and possible damage to the airplane or injury to persons on the ground.
