📄 Summary
The FAA is superseding Airworthiness Directive (AD) 2025-17- 12, which applied to all Bombardier, Inc., Model CL-600-1A11 (600) and CL-600-2A12 (601) airplanes and certain Model CL-600-2B16 (601-3A, 601- 3R, and 604 Variants) airplanes. AD 2025-17-12 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2025-17-12, the FAA has determined that certain serial numbers for affected Model CL-600-2B16 (604 Variants) airplanes are not included in the applicability of AD 2025-17-12. This AD continues to require the actions specified in AD 2025-17-12 and adds airplanes to the applicability. The FAA is issuing this AD to address the unsafe condition on these products.
