What to do
Operators must amend the approved Airplane Flight Manual by incorporating the specified warnings and emergency procedures within 30 days of the effective date, 23 June 2022. Flight crews must be advised of these changes and operate the aircraft accordingly. Compliance with these updates is mandatory to meet Canadian Aviation Regulations.
Summary
Airworthiness Directive CF-2019-12R1 is a Canadian regulatory update addressing the Auto Flight System limitations and emergency procedures related to velocity decay during low level flight using altitude capture in one engine inoperative conditions. It applies specifically to Bombardier Inc. model BD-100-1A10 aeroplanes with serial numbers 20003 through 20867. The directive mandates updates to the Airplane Flight Manual to better handle altitude capture modes during engine failure scenarios.
What changed
This revision supersedes AD CF-2019-12 by expanding the required updates to the Airplane Flight Manual to include all applicable annunciated altitude capture modes used in the affected aircraft. It clarifies the background description and mandates more comprehensive warnings and emergency procedures to address the unsafe condition of airspeed decay during altitude capture with one engine inoperative.
Why it matters
The directive is critical for flight safety as it ensures crews are better informed and prepared to manage airspeed decay risks during altitude capture phases when one engine fails. This reduces the likelihood of unsafe flight conditions and potential accidents. Operators and maintenance teams must comply to maintain regulatory approval and ensure aircraft are operated within safe limits.
