## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Bombardier Model CL-600-2B19 series airplanes. This proposal would require a one-time inspection of the fuel-level sensing wires in the center fuel tank for damage and for clearance from the adjacent structure. This proposal would also require corrective action, if necessary. This action is necessary 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.
