What to do
Operators of Bombardier BD-100-1A10 Challenger 300 and 350 aircraft must incorporate the approved temporary revision to the aircraft flight manual within 30 days of the directive's effective date. Maintenance teams must also ensure that no affected sensitive elements with date codes prior to A2105 are installed as replacement parts. Crews must be informed of the manual changes and operate aircraft accordingly.
Summary
Canadian Airworthiness Directive CF-2022-44 is a regulatory document addressing a safety issue in Bombardier BD-100-1A10 Challenger 300 and 350 aircraft. It concerns certain sensitive elements in the bleed air leak detection system that may have insufficient salt filling, potentially preventing detection of hot bleed air leaks. This directive mandates temporary revisions to the aircraft flight manual and prohibits installation of affected parts as spares.
What changed
This directive introduces a temporary revision to the aircraft flight manual to include abnormal procedures for the BLEED LOOP FAULT advisory message, preventing takeoff if a hot bleed air leak is indicated. It also bans installation of sensitive elements with potentially insufficient salt filling as replacement parts on affected aircraft. These measures are provisional pending further actions.
Why it matters
This directive is critical for operators and maintenance organizations to prevent undetected hot bleed air leaks that could damage aircraft structures and systems, compromising flight safety. Compliance ensures that flight crews are aware of abnormal procedures and that only serviceable parts are installed, reducing risk of in-flight failures and ensuring regulatory compliance.
