Airworthiness Directives; Bombardier Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL- 604) Series Airplanes

Riepilogo

This amendment adopts a new airworthiness directive (AD), applicable to certain Bombardier Model CL-600-1A11 (CL-600), CL-600- 2A12 (CL-601), and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604) series airplanes, that requires, for certain airplanes, removing the hydraulic tube assemblies from the main landing gear (MLG) bay, installing new re-routed hydraulic tube assemblies, and repositioning a fuel line, as applicable. For certain other airplanes, this amendment requires a general visual inspection to determine the routing of certain hydraulic and fuel lines, and repair, if necessary. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent damage to hydraulic and fuel lines resulting from failure of an MLG, which could cause a fire in the MLG wheel well.
