FAA Yanks Faulty Airplane Cables: Safety Snip for Regional Jets
Published Date: 1/21/2026
Rule
Summary
The FAA is requiring all MHI RJ Aviation ULC regional jets (formerly Bombardier models) to replace their elevator autopilot control cables because some have failed. This fix starts February 5, 2026, to keep flights safe and smooth. Operators should act quickly to avoid delays or extra costs from potential cable problems.
Analyzed Economic Effects
4 provisions identified: 1 benefits, 3 costs, 0 mixed.
Mandatory cable replacement for regional jets
The FAA requires all MHI RJ Aviation ULC regional jets (listed CL-600 series models) to have their elevator autopilot control cables replaced to address reported cable failures. The AD is effective February 5, 2026, affects 711 U.S.-registered airplanes, and the FAA estimates a cost per airplane of $2,535 (labor $850 + parts $1,685), with a total estimated cost to U.S. operators of $1,802,385.
Shortened compliance deadlines for many aircraft
The FAA shortened compliance times from Transport Canada by 3 months. For most U.S. airplanes with elevator autopilot cables that have over 40,000 total flight hours, the replacement must be done within 5 months after the AD's effective date (after February 5, 2026).
Possible warranty coverage reduces operator cost
The manufacturer reports some or all of the replacement costs may be covered under warranty, which could reduce the out-of-pocket cost to affected operators. The FAA notes it does not control warranty coverage.
No-passenger ferry flights allowed for modifications
Special flight permits may be issued to ferry affected airplanes to a location for modification, but only if no passengers are onboard. Operators who elect to move airplanes under a special permit cannot carry passengers during that ferry flight.
