What to do
Affected operators must amend the applicable Airplane Flight Manual or supplement within 30 days of the effective date to incorporate the navigation system limitation prohibiting editing of CLIMB TO altitudes and use of temperature compensation on the FMS. Additionally, all flight crews must be advised of these changes within the same 30-day period to ensure awareness and compliance.
Summary
Airworthiness Directive CF-2019-10 is issued by Transport Canada and applies to Bombardier Inc. model CL-600-2B16 aircraft, serial numbers 5301 and subsequent, equipped with FMS-6000 software versions 3.3.X through 4.X. This directive addresses limitations in the airplane flight manual related to the navigation system, specifically prohibiting editing of CLIMB TO altitudes and the use of temperature compensation on the Flight Management System (FMS).
What changed
This directive introduces a mandatory amendment to the Airplane Flight Manual or its supplement to include a navigation system limitation that prohibits editing CLIMB TO altitudes and using temperature compensation on the FMS. It highlights that editing these parameters can cause the FMS to command incorrect turn directions, increasing crew workload and risking airspace violations.
Why it matters
The directive is critical for aviation professionals as it prevents unsafe flight management system behavior that could lead to navigation errors and potential air traffic control conflicts. Operators and maintenance teams must ensure compliance to maintain aircraft airworthiness and operational safety. Flight crews must be informed of these limitations to avoid inadvertent FMS edits that compromise flight safety.
