Airworthiness Directives; Bombardier Model CL-600-2B19 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain Bombardier Model CL-600-2B19 series airplanes, that requires a one-time inspection of the fuel-level sensing wires in the center fuel tank for damage and for clearance from the adjacent structure; and corrective action, if necessary. The actions specified by this AD are intended to detect and correct inadequate clearance between the fuel-level sensing wires in the center fuel tank and adjacent structures, which could lead to chafing of the wires, resulting in electrical arcing between the fuel-level sensing wires and the center fuel tank and a consequent fire or explosion in the center fuel tank. This action is intended to address the identified unsafe condition.
