Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional Jet Series 100 and 200) Airplanes

摘要

This amendment adopts a new airworthiness directive (AD) that is applicable to certain Bombardier Model CL-600-2B19 (Regional Jet Series 100 and 200) airplanes. This action requires repetitive inspections to detect discrepancies of the shock strut end caps and attachment pins of the main landing gear (MLG), and replacement of discrepant parts with new parts. It also requires a check for and replacement of certain pins that currently may be installed on some airplanes. This amendment is prompted by reports of corrosion, wear, and loss of chrome plating on the upper and lower attachment pins of the shock strut of the MLG, and reports of cracks in the lower attachment pins and the end cap of upper attachment pins. The actions specified in this AD are intended to prevent failure of attachment pin and the attachment pin's end cap, which could result in failure of the MLG.
