What to do
Operators of affected Bombardier CL-600-2B16 aeroplanes must test the overheat detection sensing elements within 7800 flight cycles or 96 months from 22 February 2023, whichever occurs first. Non-serviceable sensing elements must be replaced before further flight. Additionally, installation of any affected sensing elements as replacement parts is prohibited from the effective date of the AD.
Summary
Canadian Airworthiness Directive CF-2023-05 addresses a safety issue on Bombardier Inc. model CL-600-2B16 aeroplanes, serial numbers 5580 to 5665, 5701 to 5988, and 6050 and subsequent. The directive concerns non-conforming bleed air leak detection system sensing elements that may fail to detect hot bleed air leaks due to insufficient salt fill. This AD mandates testing and replacement of affected sensing elements to ensure continued safe flight and landing.
What changed
This new Airworthiness Directive introduces mandatory testing of overheat detection sensing elements in the bleed air leak detection system for specified Bombardier CL-600-2B16 aircraft. It requires replacement of any non-conforming sensing elements and prohibits installation of affected parts as replacements. The directive references specific Bombardier and Kidde Aerospace service bulletins for compliance procedures.
Why it matters
This AD is critical for operators and maintenance organizations to prevent undetected hot bleed air leaks that could damage aircraft structures and systems, potentially compromising flight safety. Compliance ensures the reliability of the bleed air leak detection system, supporting safe aircraft operation and regulatory adherence. Maintenance teams must verify part conformity to avoid installation of defective components.
