EASA AD CF-2016-32R4
Fuel — Engine and Auxiliary Power Unit Electrical Fuel Pump Cartridge / Canister Fuel Leakage
Summary
The Airworthiness Directive CF-2016-32R4 addresses fuel leakage issues from the electrical connectors and conduits of the engine and Auxiliary Power Unit (APU) electrical fuel pump cartridge/canister on Bombardier Inc. model CL-600-2B16 aircraft, serial numbers 5301 through 6163. This directive mandates inspections and corrective actions to detect and rectify fuel leaks to mitigate potential fire hazards. It applies specifically to various serial number groups of the CL-600-2B16 and references Bombardier Service Bulletins for compliance.
What Changed
Airworthiness Directive CF-2016-32R4 revises the applicability of the previous directive and informs that compliance with AD CF-2020-38 constitutes terminating action for the periodic fuel leak inspection requirements mandated by this AD. It updates inspection intervals, incorporates revised Bombardier Service Bulletins, and extends compliance provisions based on additional in-service experience and corrective actions.
Why It Matters
This directive is critical for aviation professionals to prevent potential fire hazards caused by fuel leaks in the engine and APU electrical fuel pump systems. Operators and maintenance organizations must ensure timely inspections and repairs to maintain aircraft airworthiness and safety. Compliance with this AD helps avoid operational restrictions and ensures adherence to Canadian Aviation Regulations.
What To Do
Operators of affected Bombardier CL-600-2B16 aircraft must perform inspections and rectify any fuel leaks within 600 flight hours or 12 months, whichever occurs first, according to the specified Bombardier Service Bulletins. Repeat inspections are required at the same intervals until compliance with AD CF-2020-38 is achieved, which serves as terminating action. Aircraft inspected under earlier versions of the service bulletins must update to the latest revisions within specified timeframes.
