What to do
Operators of Bombardier CL-600-2B16 aircraft with serial numbers 5301 through 5665 must perform initial special detailed inspections within specified flight cycle compliance times based on the aircraft's total accumulated flight cycles as of July 22, 2025. Repetitive inspections must be conducted at intervals defined in the directive, ranging from 2039 to 7800 flight cycles depending on the inspection area. Any detected defects require contacting Bombardier for approved repair instructions before further flight, following Transport Canada approval if necessary.
Summary
Canadian Airworthiness Directive CF-2025-36 addresses structural inspections for Bombardier Inc. model CL-600-2B16 aircraft, serial numbers 5301 through 5665. This directive mandates detailed inspections of the fuselage, stabilizers, wings, and exhaust system components to detect cracks that could lead to structural failure. The inspections involve specific non-destructive testing procedures outlined in the CH 604 Non-Destructive Testing Manual.
What changed
CF-2025-36 introduces revised and new non-destructive testing procedures for twelve Airworthiness Limitations tasks that previously may not have detected cracks effectively. It requires initial and repetitive special detailed inspections of various structural areas including passenger and baggage doors, wing to fuselage pins, pylon spar attachments, horizontal stabilizer spars, wing planks, flap hinge box supports, and thrust reverser components. This directive is an interim action and may be followed by further regulatory measures.
Why it matters
This directive is critical for operators and maintenance organizations to prevent undetected structural cracks that could compromise aircraft safety. Compliance ensures continued airworthiness of affected Bombardier CL-600-2B16 aircraft and helps avoid potential structural failures. Maintenance and compliance teams must update inspection programs to incorporate the revised and new inspection procedures within specified flight cycle intervals.
