Must Update Maintenance Program by Feb 20, 2026
If you operate a Bombardier BD-100-1A10 airplane, you must revise your maintenance or inspection program to add the new, more restrictive airworthiness limitations within 90 days after February 20, 2026. The initial time to do the tasks is the time specified in the applicable TLMC manual or within 90 days after February 20, 2026, whichever is later.
FAA Estimates $7,650 Average Per-Operator Cost
The FAA estimates this AD affects 782 airplanes on the U.S. registry and that revising the maintenance program takes an average of 90 work-hours per operator, at $85 per hour, for an average total cost per operator of $7,650. These are the FAA's estimated compliance numbers for affected U.S. operators.
Specific TLMC Documents Required by Serial Number
Operators must incorporate Part 2, "Airworthiness Limitations," of the specified TLMC manuals: for airplanes with serial numbers 20003 through 20457 use Bombardier Challenger 300 TLMC, Publication No. CH 300 TLMC, Revision 24, dated August 9, 2023; for serial numbers 20501 through 21399 use Bombardier Challenger 350 TLMC, Publication No. CH 350 TLMC, Revision 14, dated August 9, 2023. Using a later revision is acceptable only if the later revision is identical to the referenced Part 2 material.
No Alternate Intervals Without FAA Approval
After you revise your maintenance or inspection program as required, you may not use alternative actions or intervals (for example, different inspections) unless you get an approved Alternative Method of Compliance (AMOC) from the FAA. AMOC requests must follow the procedures in 14 CFR 39.19 and be approved by the Manager, International Validation Branch, FAA.
