Summary
The FAA withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD) for certain Bombardier Model CL-600-2B16 (CL-604) series airplanes. The proposed AD would have required replacing the side-brace fitting shafts of the main landing gear (MLG) with new, improved side-brace fitting shafts; inspecting for corrosion of the MLG side-brace fitting shafts; and replacing the nut, washer, and cotter pin of the MLG side-brace fitting shafts with new parts; as applicable. Since the proposed AD was issued, we have received new data that the actions that would have been required by the proposed AD have already been accomplished on all of the affected airplanes. Accordingly, the proposed AD is withdrawn.
