EASA AD CF-2020-38
Fuel — Engine and Auxiliary Power Unit Electrical Fuel Pump Cartridge / Canister Fuel Leakage
Summary
Canadian Airworthiness Directive CF-2020-38 addresses fuel leakage issues in the engine and auxiliary power unit electrical fuel pump cartridge/canister on Bombardier Inc. CL-600-2B16 aircraft, specifically serial numbers 5301 through 5665, 5701 through 5990, and 6050 through 6163. The directive mandates modifications to the fuel boost pump canister/cartridge conduit connections to eliminate fuel leaks. This replaces previous requirements for periodic fuel leak inspections.
What Changed
CF-2020-38 cancels and supersedes AD CF-2016-32R3 by removing the need for periodic fuel leak inspections and instead requires a one-time modification of the fuel pump canister/cartridge conduit connections. Bombardier Service Bulletins 604-28-024, 605-28-012, and 650-28-002 provide the instructions for these modifications. This represents a final corrective action to address the root cause of the fuel leaks.
Why It Matters
This directive is important for operators, maintenance organizations, and compliance teams because it eliminates ongoing inspection burdens by mandating a permanent fix for fuel leaks, enhancing safety and reliability. Compliance ensures adherence to Canadian Aviation Regulations and prevents potential fuel leakage hazards during operation. It also streamlines maintenance by replacing repetitive inspections with a definitive repair.
What To Do
Operators of affected Bombardier CL-600-2B16 aircraft must inspect and modify the engine and APU electrical fuel pump installations according to the applicable Bombardier Service Bulletins listed in the directive. These actions must be completed within 60 months from the effective date of 27 October 2020. Stakeholders should coordinate with Transport Canada and approved maintenance providers to ensure compliance.
