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.

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.
2026-16803, Notice of Availability, Notice of Public Comment Period and Request for Comment on the Draft Environmental Assessment for Reditus Space ENOS Reentries in the Gulf of America
In accordance with the National Environmental Policy Act of 1969, as amended (NEPA) and FAA Order 1050.1G, FAA National Environmental Policy Act Implementing Procedures, the FAA is announcing the availability of and requesting comment on the Draft Environmental Assessment for Reditus Space ENOS Reentries in the Gulf of America (Draft EA).
2026-16795, Airworthiness Directives; The Boeing Company Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737 -300, -400, and -500 series airplanes. This proposed AD was prompted by reports of nuisance stick shaker activation while accelerating to cruise speed at the top of a climb due to frozen angle of airflow (AOA) sensor vanes. This proposed AD would require installing new external case heaters (ECHs) on the left and right AOA sensors, performing repetitive functional tests and applicable corrective actions, and accomplishing applicable concurrent actions. The FAA is proposing this AD to address the unsafe condition on these products.
2026-16804, Establishment of Class E Airspace; Trading Bay Production Airport, Trading Bay, AK
This action proposes to establish Class E airspace extending upward from 700 feet above the surface at Trading Bay Production Airport, Trading Bay, AK. This action would support the safety and management of instrument flight rules (IFR) operations at the airport.
