2026-15073Proposed Rule

Airworthiness Directives; Airbus Canada Limited Partnership (Type Certificate Previously Held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Airplanes

Published Date: 7/27/2026

Proposed Rule

Summary

The FAA proposes to supersede Airworthiness Directive (AD) 2024-22-01, which applies to certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. AD 2024-22-01 requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2024-22-01, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This proposed AD would continue to require certain actions in AD 2024-22-01 and would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is proposing this AD to address the unsafe condition on these products.

Analyzed Economic Effects

3 provisions identified: 1 benefits, 2 costs, 0 mixed.

Must revise maintenance programs

If you operate Airbus Canada Model BD-500-1A10 or BD-500-1A11 airplanes that have not already incorporated Issue No. 019.01, you must revise your existing maintenance or inspection program to include the new or more restrictive airworthiness limitations specified in Transport Canada AD CF-2025-67. The AD requires you to incorporate Airbus Canada A220 Airworthiness Limitations, BD500-3AB48-11400-02, Issue No. 019.01, dated August 28, 2025, with the compliance time to revise the maintenance or inspection program within 30 days after the effective date of this AD.

FAA estimates compliance labor costs

The FAA estimates this AD would affect 184 U.S.-registered airplanes. The agency estimates the cost per operator to revise and implement the maintenance/inspection program is 90 work-hours at $85 per hour, equal to $7,650 for the retained actions from AD 2024-22-01, and it estimates an average of 90 work-hours (also $7,650) per operator for the new proposed actions.

Incorporating Issue 019.01 ends CCMR requirement

After you incorporate Airbus Canada A220 Airworthiness Limitations Issue No. 019.01 (dated August 28, 2025) into your maintenance or inspection program, the AD terminates the prior requirement to incorporate Candidate Certification Maintenance Requirements (CCMRs). The AD states the initial compliance times for tasks in Issue No. 019.01 are at the applicable thresholds or within 30 days after the effective date of this AD, whichever occurs later.
