What to do
Operators of affected Bombardier BD-700-1A10 and BD-700-1A11 aircraft must amend their Transport Canada approved maintenance schedules within 30 days of the directive's effective date to include the new CMR tasks. Initial compliance with these tasks must be achieved before accumulating specified flight hours or within 30 days, whichever is later. Subsequent maintenance must follow intervals outlined in the relevant Time Limits/Maintenance Checks manuals or later approved revisions.
Summary
Canadian Airworthiness Directive CF-2022-15 introduces new Certification Maintenance Requirements (CMRs) for Bombardier Inc. model BD-700-1A10 and BD-700-1A11 aeroplanes with specific serial numbers. This directive mandates updates to maintenance schedules to include new tasks related to landing gear emergency extension, brake shutoff valve operation, and passenger door vent-flap mechanism checks. The directive aims to enhance safety by addressing maintenance tasks that have reached escalation limits.
What changed
CF-2022-15 requires incorporation of three new CMR tasks into the approved maintenance schedules for affected Bombardier BD-700-1A10 and BD-700-1A11 aircraft. These tasks replace previous Maintenance Review Board Report tasks and introduce reduced intervals to prevent unsafe conditions. The directive specifies initial compliance times and mandates repeating these tasks at intervals defined in the applicable Time Limits/Maintenance Checks manuals.
Why it matters
This directive ensures continued airworthiness by preventing escalation of critical maintenance tasks that could compromise safety. Operators, maintenance organizations, and compliance teams must update their maintenance programs to align with the new CMRs, thereby avoiding regulatory non-compliance and potential operational disruptions. Timely incorporation of these requirements helps maintain aircraft reliability and safety standards.
