Summary
This document revises an earlier proposed airworthiness directive (AD), applicable to certain EMBRAER Model EMB-135 and EMB-145 series airplanes, that would have required inspection of the housings of the main landing gear (MLG) leg strut bushings; repair of the housings if necessary; and replacement of the MLG leg strut bushings with new bushings. This new action revises the proposed rule by requiring inspection of additional MLG leg strut bushings; removing the requirement to replace the MLG leg strut bushings; and clarifying that related investigative and corrective actions must be accomplished. The actions specified by this new proposed AD are intended to prevent corrosion of the housings of the MLG leg strut bushings and consequent failure of the MLG. This action is intended to address the identified unsafe condition.
