What to do
Operators of affected MHI RJ Aviation ULC CL-600-2B19 aircraft must replace the serrated hook assemblies and support tubes on overhead bins within 6000 flight hours or 44 months from the effective date of October 30, 2023, whichever occurs first. The replacement must follow the instructions in section 2B of MHI RJ Aviation ULC Service Bulletin 601R-25-206, Initial Issue dated June 29, 2023, or later approved revisions. Contact Transport Canada for further guidance if needed.
Summary
Canadian Airworthiness Directive CF-2023-71 addresses a potential failure in the overhead bin attachments on MHI RJ Aviation ULC model CL-600-2B19 aircraft. The directive applies to specific serial numbers of this aircraft type and mandates modifications to the overhead storage compartments to ensure safety during emergency landing conditions. This directive aims to prevent overhead bins from detaching and causing injury or obstructing emergency exits.
What changed
CF-2023-71 introduces a requirement to replace the existing serrated hook assemblies and serrated support tubes on overhead bins with assemblies using shear pins and non-serrated support tubes. This change is based on findings that the original serrated hooks could fail under 9G forward emergency landing conditions due to tolerance build-up. The directive mandates compliance with MHI RJ Aviation ULC Service Bulletin 601R-25-206.
Why it matters
This directive is critical for aviation professionals as it addresses a safety risk that could lead to overhead bins detaching during emergency landings, potentially injuring occupants or blocking emergency exits. Operators, maintenance organizations, and compliance teams must ensure timely modifications to maintain aircraft airworthiness and regulatory compliance. Failure to comply could result in unsafe conditions and regulatory penalties.
