## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes, that requires a one-time inspection of the shafts of the main landing gear (MLG) side-brace fittings to detect corrosion, and the forward and aft bushings in the left-hand and right-hand MLG side-brace fittings to detect discrepancies. This AD also requires corrective and related actions if necessary. This action is necessary to prevent fractures of the MLG side-brace fitting shafts, and possible collapse of the MLG. This action is intended to address the identified unsafe condition.
