What to do
Operators of affected Bombardier BD-700-1A10 and BD-700-1A11 aircraft must inspect the engine driven pump hydraulic hoses within 500 flight hours or 18 months from March 6, 2024, whichever occurs first. If damage or insufficient clearance is found, hoses must be replaced or adjusted before further flight. Compliance must follow the procedures outlined in the applicable Bombardier Service Bulletins.
Summary
Canadian Airworthiness Directive CF-2024-07 addresses hydraulic power issues related to engine driven pump hydraulic hoses fouling with the pylon on Bombardier Inc. model BD-700-1A10 and BD-700-1A11 aircraft, specifically serial numbers 60001 through 60076, 60083, 60087, and 60089. The directive mandates inspections and corrective actions to prevent hydraulic hose chafing that could lead to system leaks and failures. This AD aims to maintain the integrity of hydraulic systems No. 1 and No. 2 on these aircraft.
What changed
CF-2024-07 introduces a new requirement for inspecting the routing and condition of engine driven pump hydraulic hoses on affected Bombardier BD-700 models. It requires operators to inspect for damage and minimum clearance between hoses and the pylon, and to replace or adjust hoses as necessary. This is a new airworthiness directive issued to address in-service reports of hose chafing.
Why it matters
This directive is critical for aviation professionals because hydraulic system failures can severely reduce aircraft functionality and safety. Operators and maintenance teams must ensure compliance to prevent leaks and potential loss of hydraulic systems, which could impact flight control and other essential systems. Timely inspections and corrective actions help maintain aircraft airworthiness and operational reliability.
