EASA AD CF-2021-39
Doors — Emergency Exits — Overwing Emergency Exit Door Handle Cover — Opening Force Exceeds Design Limits
Summary
Canadian Airworthiness Directive CF-2021-39 addresses an issue with the overwing emergency exit door handle cover on Airbus Canada Limited Partnership aircraft models BD-500-1A10 and BD-500-1A11. The directive identifies that the handle cover brackets may require excessive force to open, potentially hindering emergency evacuation. This AD mandates corrective action to ensure compliance with safety standards.
What Changed
CF-2021-39 introduces a requirement to replace the overwing emergency exit door handle cover brackets on specified Airbus Canada BD-500-1A10 and BD-500-1A11 aircraft. The replacement uses a redesigned bracket to reduce the force needed to open the handle cover, addressing the flexure issue found during final assembly. This is a new regulation aimed at improving emergency exit accessibility.
Why It Matters
This directive is critical for operators and maintenance organizations because it ensures that emergency exits can be opened easily in an emergency, which is vital for passenger safety. Compliance prevents potential delays or complications during evacuation and helps maintain regulatory adherence under Canadian Aviation Regulations. It also guides maintenance teams on necessary modifications to avoid operational disruptions.
What To Do
Operators of affected Airbus Canada BD-500-1A10 and BD-500-1A11 aircraft must remove and replace the overwing emergency exit door handle cover brackets following Airbus Canada Service Bulletin BD500-252035, Issue 001, or later approved revisions. This action must be completed within six months from the effective date of 24 November 2021 unless already done. Contact Transport Canada for further guidance if needed.
