What to do
Operators of Bombardier CL-600-2B16 aircraft must perform ultrasonic and eddy current inspections on the specified structural areas before reaching defined flight cycle thresholds or within specified intervals from previous inspections. If cracks are found, they must contact Bombardier for repair instructions and complete repairs before further flight. Compliance deadlines vary by aircraft serial number and accumulated flight cycles, with the earliest effective date being 6 January 2025.
Summary
The Airworthiness Directive CF-2024-47 issued by Transport Canada mandates inspections and potential repairs for Bombardier Inc. model CL-600-2B16 aircraft, serial numbers 5301 through 5665. The directive addresses cracks found in critical structural areas including the lower wing plank at the rear spar, vertical stabilizer front spar to frame attachment fittings, and the pressure bulkhead web between specific buttock lines. This directive ensures continued airworthiness by requiring detailed ultrasonic and eddy current inspections.
What changed
CF-2024-47 introduces mandatory special detailed inspections using ultrasonic and eddy current techniques on specific structural components of the Bombardier CL-600-2B16 aircraft. It establishes compliance timelines based on flight cycles and requires contacting Bombardier for repair instructions if cracks are detected. This directive is an interim measure pending further actions.
Why it matters
This directive is critical for aviation professionals as it addresses potential undetected structural cracks that could lead to catastrophic failure. Operators and maintenance organizations must comply to ensure aircraft structural integrity and safety. Compliance teams need to integrate these inspections into maintenance schedules to avoid grounding or regulatory non-compliance.
