What to do
Operators must amend the applicable Transport Canada approved AFM within 60 days of the effective date by incorporating the specified warnings and abnormal procedures related to engine failure during altitude capture. Flight crews must be informed of these changes and operate the aircraft in accordance with the updated AFM. The effective date for compliance is 25 July 2022.
Summary
Airworthiness Directive CF-2022-37 is a Canadian regulatory document addressing the Auto Flight System limitations and abnormal procedures related to velocity decay during low-level altitude capture in one engine inoperative conditions. It applies to Mitsubishi Heavy Industries RJ Aviation ULC models CL-600-2B19, CL-600-2C10, CL-600-2C11, CL-600-2D15, CL-600-2D24, and CL-600-2E25 aircraft. The directive mandates updates to the Airplane Flight Manual (AFM) to enhance safety during engine failure scenarios in climb phases.
What changed
This directive supersedes AD CF-2018-32R1 and requires amendments to the AFM Limitations and Abnormal Procedures sections to include warnings and procedures addressing the risk of significant airspeed decay during altitude capture when one engine is inoperative. It introduces specific guidance for aircraft equipped with coupled vertical navigation (CVNAV) systems and distinguishes procedures based on the presence or absence of this option.
Why it matters
The changes are critical for flight crews and operators to prevent unsafe airspeed reductions during climb phases with one engine inoperative, which could compromise flight safety. Compliance ensures that crews are informed and prepared to intervene promptly, maintaining safe operating speeds and adhering to regulatory requirements. Maintenance and compliance teams must update documentation and training accordingly to meet Transport Canada standards.
