FAA Proposes Broader Airworthiness Rules for Bombardier Planes

Published Date: 10/21/2025

Proposed Rule

Summary

The FAA wants to update safety rules for certain Bombardier airplanes, including some new models that weren’t covered before. This means owners must follow stricter maintenance checks to keep flying safe. Comments on these changes are open until November 20, 2025, and while it might cost some money, it’s all about keeping passengers and crews safe in the sky.

Analyzed Economic Effects

5 provisions identified: 0 benefits, 5 costs, 0 mixed.

FAA cost estimate: $7,650 per operator

The FAA estimates this AD would affect 427 U.S.-registered airplanes. The agency estimates the total cost per operator for the retained actions from AD 2025-17-12 is $7,650 (90 work-hours × $85/hour), and it also estimates $7,650 (90 work-hours × $85/hour) per operator for the new proposed actions.

New airplane serial numbers added

The FAA would expand the AD to apply to more Bombardier airplanes. The rule would apply to all Model CL-600-1A11 (600), CL-600-2A12 (601), CL-600-2B16 (601-3A and 601-3R) airplanes, and Model CL-600-2B16 (604 Variant) airplanes with S/Ns 5301–5665, 5701–6049, and 6050–6192.

Must revise maintenance programs in 90 days

Operators must revise their maintenance or inspection programs to add the specified airworthiness limitations. For airplanes in paragraphs (c)(1) and (c)(3), revisions must be done within 90 days after October 31, 2025. For airplanes listed in paragraph (c)(2), revisions must be done within 90 days after the effective date of this AD.

HSTA inspection timing: 12-year rules

For certain airplanes in paragraph (c)(2), the initial compliance time for task 27-42-01-110 (Special Detailed Inspection of the Horizontal Stabilizer Trim Actuator, P/N 604-92305-7) is either within 12 years after accomplishing a prior replacement or within 12 years from the part entry into service for parts manufactured before November 1, 2015.

No alternative intervals without FAA approval

After operators revise their maintenance or inspection programs as required, they may not use alternative actions or intervals unless an Alternative Method of Compliance (AMOC) is approved under the AD's procedures (14 CFR 39.19).
