Electrical Power - Electrical Wires Chafing With Auxiliary Aft Cabin Fuel Tank Bracket
Summary
Canadian Airworthiness Directive CF-2019-22 addresses an electrical wiring issue on Bombardier Inc. CL-600-2B19 aircraft. The directive targets specific serial numbers of this model where generator power cables may chafe against the auxiliary aft cabin fuel tank bracket. This condition could lead to electrical short circuits and generator malfunctions.

Why It Matters
This directive is critical for operators and maintenance teams to prevent potential electrical failures that could compromise aircraft safety. Addressing the chafing issue reduces the risk of generator malfunction and electrical shorts, which are serious safety hazards. Compliance ensures continued airworthiness and regulatory adherence.
What To Do
Operators of affected Bombardier CL-600-2B19 aircraft must inspect and correct the wiring condition following the instructions in Bombardier Service Bulletin 601R-24-131.
