What to do
Operators of affected Bombardier CL-600-1A11, CL-600-2A12, and CL-600-2B16 aircraft must inspect and modify the portable oxygen bottle installations within 60 months from the effective date of 2019-07-23. The modifications must be performed in accordance with the applicable Bombardier Service Bulletins or approved Supplemental Type Certificates. Contact Transport Canada for further guidance if needed.
Summary
Canadian Airworthiness Directive CF-2019-26 addresses accessibility issues with portable oxygen bottles installed on Bombardier CL-600 series aeroplanes, specifically models CL-600-1A11, CL-600-2A12, and CL-600-2B16. The directive mandates modifications to the upper and middle brackets of Scott (Avox/Zodiac) 5500 or 5600 series 11 cubic foot portable oxygen bottles to ensure they can be easily removed in emergencies. This AD applies to specific serial numbers of these aircraft equipped with certain bracket part numbers.
What changed
This Airworthiness Directive introduces a requirement to inspect and rework affected portable oxygen bottle installations by installing a modified upper bracket and a new middle bracket. The change addresses the issue where the upper bracket latch could catch on the pressure gauge, hindering quick removal of the oxygen bottle. Compliance involves following Bombardier Service Bulletins or approved Supplemental Type Certificates.
Why it matters
Ensuring quick and reliable access to portable oxygen bottles is critical for flight attendant safety during emergencies. This AD impacts operators and maintenance organizations by requiring modifications that improve emergency equipment accessibility, thereby enhancing onboard safety and regulatory compliance. Failure to comply could result in operational restrictions or safety risks during emergency situations.
