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.

2026-15585, Requirements for Interference-Tolerant Radio Altimeter Systems
In July 2025, President Trump signed the One Big Beautiful Bill Act. Section 40002 of that law re-institutes the Federal Communications Commission's general auction authority and specifically directs the Commission to complete a system of competitive bidding for not less than 100 megahertz in the 3.98-4.2 gigahertz band (Upper C- band). This final rule supports the Federal Communications Commission's July 2026 Report and Order that makes 160 megahertz of the Upper C-band available for terrestrial wireless flexible use via a system of competitive bidding. To ensure safe, efficient, and reliable aviation operations in the presence of wireless signals in the C-band, the Federal Aviation Administration is issuing new regulations that require all radio altimeters to meet specific minimum performance requirements. These new radio altimeters must withstand interference from wireless signals in neighboring spectrum bands and continue to provide accurate altitude readings to both pilots and integrated aircraft safety systems. These regulations require all aircraft equipped with radio altimeters operating under part 121 and those aircraft with radio altimeters operating under part 129 with 30 or more passenger seats or a payload capacity of more than 7,500 pounds to comply with the minimum performance requirements by December 30, 2030, which is prior to the date the Federal Communications Commission authorizes the use of the Upper C-band for new wireless services, as stated in its Report and Order. All other aircraft equipped with radio altimeters that are required to comply with part 91, including aircraft operating under parts 125, 133, 135, 136, 137, 194, and all other aircraft operating under part 129 that are not subject to the initial deadline, must comply with the same minimum performance requirements on or before October 31, 2034.
2026-13440, Enabling Supersonic Overland Flight
The FAA wants to let supersonic planes fly over land again by updating old rules that banned them because of loud sonic booms. Thanks to new tech that keeps booms quiet, this change will open the door for faster, cooler flights across the U.S., helping America lead the world in supersonic travel. People and companies interested in supersonic flight should share their thoughts by August 17, 2026.
2026-13126, Designation-Restrict the Operation of Unmanned Aircraft in Close Proximity to a Fixed Site Facility; Extension of Comment Period
The FAA is giving more time—until August 5, 2026—for people to share their thoughts on new rules that would limit drone flights near important fixed sites like power plants or airports. This affects drone operators and facility owners who want to keep the skies safe and secure. No new costs yet, just extra time to weigh in and help shape the rules.
2026-08943, Designation-Restrict the Operation of Unmanned Aircraft in Close Proximity to a Fixed Site Facility
The FAA is proposing new rules to keep drones away from certain important fixed sites like power plants or airports to keep everyone safe and secure. If you own or operate one of these sites, you can request a drone flight restriction zone to protect your property and people nearby. Comments are open until July 6, 2026, and these changes could affect drone pilots and site operators, but no big costs are expected.
2026-18601, Airworthiness Directives; Dassault Aviation Airplanes
The FAA is superseding Airworthiness Directive (AD) 2023-23- 06, which applied to certain Dassault Aviation Model FALCON 2000EX airplanes. AD 2023-23-06 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2023-23- 06, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This AD continues to require certain actions in AD 2023-23-06 and requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) 2023-22- 12, which applied to all Dassault Aviation Model FALCON 2000 airplanes. AD 2023-22-12 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2023-22-12, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This AD continues to require certain actions in AD 2023- 22-12 and requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations.
