What to do
Operators must amend the Airplane Flight Manual within 7 days of the effective date to include the new autopilot engagement warning or carry the directive on board. Flight crews must be informed of the new limitation and operate the aircraft accordingly. The directive also advises crews not to attempt re-engagement of the autothrottle if disconnected during takeoff under specified conditions.
Summary
Canadian Airworthiness Directive CF-2022-64 is an emergency directive affecting Airbus Canada Limited Partnership aeroplanes Model BD-500-1A10 and BD-500-1A11. It addresses the risk of inadvertent autopilot engagement during takeoff, which can lead to premature rotation and potential loss of control. The directive mandates amendments to the Airplane Flight Manual to include warnings about autopilot use during takeoff.
What changed
This new Airworthiness Directive introduces a requirement to amend the Airplane Flight Manual to include a warning against autopilot engagement during takeoff roll. It also provides operational recommendations from Airbus Canada regarding autothrottle use and prohibits re-engagement of the autothrottle after disconnection above 60 knots and below 400 feet. The directive is considered interim and may be followed by further actions.
Why it matters
This directive is critical for flight crews and operators to prevent unsafe conditions caused by autopilot engagement below 400 feet during takeoff, which can cause premature pitch-up and tail strikes. Compliance ensures safer takeoff procedures and reduces the risk of accidents related to autopilot and autothrottle misuse. Maintenance and compliance teams must update manuals and inform crews promptly to meet regulatory requirements.
