FAA Proposes Stricter Inspections for MHI RJ Aviation Planes
Published Date: 3/17/2026
Proposed Rule
Summary
The FAA wants to update safety rules for certain MHI RJ Aviation regional jets (formerly Bombardier models) by adding stricter maintenance checks. This means airlines must follow new or tougher inspection schedules to keep these planes safe. Comments on this proposal are open until May 1, 2026, and while it may cost some money, it’s all about keeping passengers flying safely.
Analyzed Economic Effects
2 provisions identified: 1 benefits, 1 costs, 0 mixed.
Operators Must Update Maintenance Programs
If you operate the listed MHI RJ (formerly Bombardier) models, you must revise your maintenance or inspection program to add new or more restrictive airworthiness limitations. The rule applies to Model CL-600-2C10, CL-600-2C11, CL-600-2D15, and CL-600-2D24 airplanes, affects 589 U.S.-registered airplanes, and requires compliance within 30 days after the AD's effective date (or at the specified threshold/discard time). The FAA estimates revising programs averages 90 work-hours per operator (90 x $85/hr = $7,650 per operator).
Stricter Inspections to Prevent Structural Failure
The AD requires adding new or more restrictive structural inspections and safe-life limits to address an unsafe condition that could lead to loss of structural integrity. The requirement incorporates Transport Canada AD CF-2025-26 (dated May 6, 2025) and applies to the same CL-600-series regional jet models listed in the proposed rule to improve safety for passengers and crews.
