This directive is critical for operators and maintenance organizations to prevent damage to passenger doors and avoid safety hazards to personnel caused by rapid door openings. Compliance ensures that maintenance practices align with the latest safety standards, reducing the risk of injury and costly repairs. It also supports regulatory compliance under Canadian aviation regulations.
What To Do
Operators and maintenance personnel must use the revised AMM tasks dated May 19, 2021, or later when performing maintenance on passenger doors of the specified Bombardier BD-700-1A10 and BD-700-1A11 aircraft.
