What to do
Operators of affected Bombardier CL-600-2B16 (604 variant) aircraft must amend the Airplane Flight Manual with the approved revisions by Transport Canada within 60 days of the effective date, January 18, 2023. Additionally, all flight crews must be briefed on the changes and operate the aircraft according to the revised procedures. Compliance with these actions is mandatory to continue legal operation of the aircraft.
Summary
Canadian Airworthiness Directive CF-2023-01 addresses an issue with Bombardier Inc. model CL-600-2B16 (604 variant) aeroplanes, specifically serial numbers 5301 through 5665, 5701 through 5988, and 6050 through 6174. The directive focuses on preventing ground spoilers from deploying in flight due to faults in the proximity sensor electronic unit (PSEU). It mandates updates to the Airplane Flight Manual to include new procedures for handling ground spoilers and weight-on-wheels input faults.
What changed
CF-2023-01 introduces a mandatory revision to the Airplane Flight Manual for affected Bombardier CL-600-2B16 (604 variant) aircraft. The updated manual includes additional instructions for the Ground Spoilers Unsafe and Weight-on-Wheels Input Fault Abnormal Procedures to prevent inadvertent deployment of ground spoilers in flight. Flight crews must be informed of these changes and operate the aircraft accordingly.
Why it matters
This directive is critical for aviation professionals because inadvertent deployment of ground spoilers in flight can compromise aircraft safety during approach and landing. Operators and maintenance teams must ensure compliance to avoid potential accidents and maintain airworthiness. The update also clarifies procedures for flight crews, enhancing operational safety and regulatory compliance.
