What to do
Affected operators must inspect and rework all portable oxygen bottle installations within 60 months from the effective date of the original AD CF-2019-26 (by 23 July 2024). The rework involves installing a modified upper bracket and a new middle bracket following the applicable Bombardier service bulletin or approved supplemental type certificate. Operators should coordinate with Transport Canada or approved maintenance organizations to ensure compliance.
Summary
Canadian Airworthiness Directive CF-2024-09 addresses insufficient accessibility to portable oxygen bottles on Bombardier Inc. aeroplanes, specifically models CL-600-1A11, CL-600-2A12, and CL-600-2B16 equipped with Scott (Avox/Zodiac) 5500 or 5600 series 11 cubic foot portable oxygen bottles with certain upper bracket part numbers. The directive ensures that portable oxygen bottles can be easily removed in emergencies by flight attendants. It applies to specific serial numbers of these aircraft models.
What changed
CF-2024-09 supersedes AD CF-2019-26 and retains its requirements while expanding applicability to include four additional CL-600-2B16 aeroplanes. It mandates inspection and rework of affected portable oxygen bottle installations to install a modified upper bracket and a new middle bracket according to Bombardier service bulletins or approved supplemental type certificates.
Why it matters
This directive is critical for aviation professionals to ensure that portable oxygen bottles are readily accessible during emergencies, which is essential for passenger safety when flight attendants are on board. Operators, maintenance organizations, and compliance teams must address the bracket design issues to meet regulatory requirements and maintain airworthiness. Failure to comply could result in regulatory penalties and compromised emergency response capability.
