FAA Issues Superseding AD on Bombardier CL-600 Landing Gear Parts

The FAA has issued a superseding Airworthiness Directive (AD) for the Bombardier Challenger CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), and CL-600-2B16 (CL-601-3A, CL-601-3R and CL-604). It requires operators to assign serial numbers or part numbers to certain landing-gear parts; establish the number of landings on the parts, if necessary; and revise the Airworthiness Limitations Section of the Instructions for Continued Airworthiness (ICA). It is intended to prevent use of life-limited landing gear parts beyond their safe-life limits, which could lead to collapse of the landing gear. This AD becomes effective September 25.
