What to do
Operators must amend the Transport Canada approved AFM with the specified revisions within 30 days of the directive's effective date. Flight crews must be informed of these changes and operate the affected aircraft according to the updated procedures. The directive also provides contact information for further assistance and alternative means of compliance.
Summary
Airworthiness Directive CF-2022-45 is issued by Transport Canada and addresses the Auto Flight System limitations and procedures related to velocity decay during low level altitude capture modes (V ALTS CAP or V ALTV CAP) in one engine inoperative conditions. This directive applies specifically to Bombardier Inc. CL-600-2B16 aircraft, serial numbers 5301 through 5665, 5701 through 5988, and 6050 through 6160. It mandates updates to the Airplane Flight Manual (AFM) to ensure safe operation during engine failure scenarios in these flight modes.
What changed
CF-2022-45 introduces mandatory revisions to the AFM limitations and emergency procedures for the affected Bombardier CL-600-2B16 aircraft to address rapid airspeed decay during altitude capture modes when one engine is inoperative. It corrects previous applicability errors from earlier directives and adds warnings and new procedures for pitch attitude adjustment to maintain safe airspeed during climbs in these modes.
Why it matters
This directive is critical for flight crews and operators to prevent unsafe airspeed decay that can occur during altitude capture with one engine inoperative, which could compromise flight safety. Compliance ensures that crews are aware of the risk and have clear procedures to maintain safe operating speeds, reducing the likelihood of incidents related to autopilot guidance during engine failure conditions.
