What to do
Operators of affected Bombardier BD-100-1A10 aircraft must amend the applicable Airplane Flight Manual Supplement within 30 days of the effective date to include the navigation system limitations. Additionally, all flight crews must be informed of these changes within the same 30-day period to ensure compliance and safe operation.
Summary
Airworthiness Directive CF-2019-09 is issued by Transport Canada and applies to Bombardier Inc. model BD-100-1A10 aircraft, serial numbers 20002 and subsequent, equipped with FMS-5000 software version 4.X. The directive addresses limitations in the airplane flight manual related to the navigation system, specifically prohibiting editing CLIMB TO altitudes and the use of temperature compensation on the Flight Management System (FMS).
What changed
This new Airworthiness Directive introduces a mandatory amendment to the Airplane Flight Manual or its supplement to prohibit flight crews from editing CLIMB TO altitudes and using temperature compensation on the FMS. It also requires operators to notify all flight crews of these changes within 30 days of the directive's effective date.
Why it matters
The directive prevents unsafe flight management system behavior where editing CLIMB TO altitudes or activating temperature compensation can cause incorrect turn commands, increasing crew workload and risking airspace violations. Compliance ensures safe navigation and reduces the risk of operational errors for operators and flight crews.
