FAA proposes structural inspections for Bombardier aircraft and notes Airbus Canada corrosion directive

The Federal Aviation Administration (FAA) is proposing aircraft safety inspections and corrective actions, not soliciting a procurement. - Government buyer: U.S. Department of Transportation, Federal Aviation Administration. - OEMs: Bombardier, Inc. and Airbus Canada Limited Partnership. - For certain Bombardier CL-600-2B16 (604 Variants), the proposal calls for inspections of specified lower-wing, pressure-bulkhead, and vertical-stabilizer structures, with repairs or rectification as applicable. - The FAA estimates 201 U.S.-registered aircraft would be affected; inspections are estimated to cost up to $2,040 per aircraft, with repair costs undetermined. - The attachment also describes a proposed directive for Airbus Canada BD-500-1A10 and BD-500-1A11 airplanes addressing corrosion around the aft waste service port. - The Bombardier inspection and repair procedures reference Transport Canada’s airworthiness directive CF-2024-47.

Description

The FAA proposes a new airworthiness directive for certain Bombardier, Inc., Model CL-600-2B16 (604 Variants) airplanes. The proposal follows reports of cracks in the lower wing plank at the rear spar wing station 59 to 65 web and/or flange, with investigation indicating inspection procedures could allow cracks to go undetected. It would require inspections for cracks of the lower wing plank rear spar web and lower flange, the pressure bulkhead frame, and the vertical stabilizer front spar attachment fitting lower legs, with repair or rectification where applicable. Comments are due December 28, 2026.
