What to do
Operators of Bombardier BD-100-1A10 aeroplanes must revise the Airplane Flight Manual Electrical Emergency and Non-Normal Procedures as specified in the directive within 60 days of the effective date, December 1, 2020. Flight crews must be informed of these changes and trained to follow the updated procedures. Continued operation of the aircraft must adhere to these revised manuals to maintain compliance and safety.
Summary
Canadian Airworthiness Directive CF-2020-46 addresses misleading electrical power indications on Bombardier Inc. model BD-100-1A10 aeroplanes, serial numbers 20003 and subsequent. The directive mandates revisions to the Electrical Emergency and Non-Normal Procedures in the Airplane Flight Manual to prevent pilots from turning off active electrical power sources during erroneous indications. This AD aims to enhance flight safety by mitigating risks of electrical power loss and associated loss of flight displays.
What changed
This new Airworthiness Directive introduces a requirement to amend the Airplane Flight Manual for affected Bombardier BD-100-1A10 aircraft, incorporating updated Electrical Emergency and Non-Normal Procedures. It also requires flight crews to be advised of these changes and to operate the aircraft accordingly. The directive does not amend hardware but focuses on procedural updates to address the unsafe condition.
Why it matters
This directive is critical for operators and maintenance teams as it addresses a safety risk involving misleading electrical system indications that could lead to partial or complete loss of electrical power and flight displays. Compliance ensures pilots are properly informed to avoid incorrect actions that could compromise aircraft controllability. It supports regulatory compliance and enhances operational safety for affected Bombardier aircraft.
