MHI RJ Jets Face New FAA Inspection Orders
Published Date: 12/12/2025
Rule
Summary
The FAA is updating safety rules for certain MHI RJ Aviation ULC regional jets, including models 700 through 1000. Owners must update their maintenance plans with new, stricter checks to keep these planes safe. This change kicks in on January 16, 2026, and while it might mean a bit more work, it helps prevent safety issues down the line.
Analyzed Economic Effects
3 provisions identified: 1 benefits, 2 costs, 0 mixed.
Mandatory maintenance program revisions
Operators of MHI RJ regional jets (models CL-600-2C10, CL-600-2C11, CL-600-2D15, CL-600-2D24, and CL-600-2E25) must revise their existing maintenance or inspection program to incorporate the new or more restrictive airworthiness limitations specified in Transport Canada AD CF-2024-41 (dated December 5, 2024) and MHI RJ MRM CSP B-053 Part 2, Revision 27 (dated September 15, 2023) as modified by this AD. This requirement is effective January 16, 2026, and includes initial compliance timing rules (tasks with thresholds/discard times: at the specified thresholds or within 30 days after the effective date, whichever occurs later; tasks with only intervals: before the applicable interval since original certificate issuance or within 30 days after the effective date, whichever occurs later).
Estimated compliance cost and fleet size
The FAA estimates this AD affects 600 U.S.-registered airplanes. The agency estimates revising the existing maintenance or inspection program takes an average of 90 work-hours per operator at $85 per work-hour, for an average total cost per operator of $7,650 (90 × $85).
Terminates certain prior AD obligations
Completing the actions required by this AD terminates the corresponding requirements of paragraph (h) of AD 2023-09-02 and paragraph (h) of AD 2023-24-03 for the identified AMM tasks, and it terminates all requirements of AD 2023-06-06 and AD 2025-11-11. Operators who accomplish this AD no longer must comply with those specific earlier AD requirements as described.

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.
2025-04846, Extension of the Prohibition Against Certain Flights in the Territory and Airspace of Libya
The FAA is extending the ban on certain flights over Libya for three more years, until March 20, 2028. This affects U.S. airlines, commercial operators, and pilots with FAA certificates flying in Libyan airspace, due to ongoing safety risks. The rule also reminds everyone how to apply for special approvals or exemptions if needed.
2025-03853, Enforcement Policy Regarding “Drug and Alcohol Testing of Certificated Repair Station Employees Located Outside of the United States; Correction”
The FAA is giving repair stations outside the U.S. a break by delaying enforcement of new drug and alcohol testing rules until March 20, 2025. This means affected repair stations don’t have to worry about penalties if they aren’t fully following the updated rules just yet. The delay helps everyone get ready without rushing or extra costs.
