What to do
Operators must amend the Aircraft Flight Manual to include the new Normal and Non-Normal Procedures as specified in the directive. Flight crews should be informed of these changes and operate the aircraft accordingly. Compliance with these actions is required within 30 days from the effective date of 2021-12-09 unless already accomplished.
Summary
Canadian Airworthiness Directive CF-2021-44 addresses an unsafe condition affecting Airbus Canada Limited Partnership BD-500-1A10 and BD-500-1A11 aircraft models. The directive introduces new procedures in the Aircraft Flight Manual related to engine thrust lever handling to prevent dual engine automatic shutdowns upon landing caused by erroneous uncontrolled high thrust detection above 16,000 feet.
What changed
This directive introduces interim amendments to the Aircraft Flight Manual by adding a new Normal Procedure for abrupt thrust lever movements above 16,000 feet and supplements existing Non-Normal Procedures for L THROTTLE FAIL and R THROTTLE FAIL cautions. These procedural changes aim to mitigate the risk of automatic dual engine shutdown on landing by prescribing specific landing preparations and actions.
Why it matters
The directive is critical for operators and flight crews as it addresses a safety risk that could lead to runway excursions due to unexpected engine shutdowns. Compliance ensures safer handling of the affected aircraft during approach and landing phases, reducing the likelihood of incidents related to thrust lever mismanagement. Maintenance and compliance teams must update manuals and train crews accordingly to meet regulatory requirements.
