What to do
Operators must amend the AFM within 30 days of the previous AD's effective date by adding interim normal and non-normal procedures, or comply via the Global AMOC. Within 120 days of CF-2022-11's effective date (31 March 2022), operators must incorporate the final procedures from Master AFM Issue 018 and remove interim changes. Flight crews must be informed of these changes and operate accordingly to ensure safety and regulatory compliance.
Summary
Airworthiness Directive CF-2022-11 is issued by Transport Canada and addresses erroneous uncontrolled high thrust detection in Airbus Canada Limited Partnership BD-500-1A10 and BD-500-1A11 aircraft models. This directive mandates updates to the Airplane Flight Manual (AFM) normal and non-normal procedures to mitigate the risk of dual engine automatic shutdown upon landing caused by abrupt thrust lever movements above 16,000 feet. The directive supersedes a previous AD and introduces final procedural changes to enhance flight safety.
What changed
CF-2022-11 supersedes AD CF-2021-44 and mandates incorporation of updated normal and non-normal procedures from the Master AFM Issue 018 into the AFM. It retains interim procedures from the previous AD, provides credit for an associated Global AMOC, and requires removal of earlier interim changes after final procedures are incorporated. The directive also introduces specific operational landing distance factors and procedural steps for handling abrupt thrust lever movements and throttle failures.
Why it matters
This directive is critical for operators and maintenance teams as it addresses a safety risk involving unexpected engine shutdowns that could lead to runway excursions. Compliance ensures that flight crews are equipped with updated procedures to manage thrust lever anomalies safely, reducing the risk of accidents during landing. It also maintains regulatory compliance with Canadian Aviation Regulations and Transport Canada requirements.
