FAA Mandates Fixes for Bombardier Plane Stabilizers
Published Date: 7/2/2025
Proposed Rule
Summary
If you fly a Bombardier BD-100-1A10, listen up! The FAA wants to make sure some important parts in your plane’s stabilizer are the right ones and not reused by mistake. They’re asking for checks and possible replacements soon to keep everyone safe and sound in the skies.
Analyzed Economic Effects
3 provisions identified: 0 benefits, 3 costs, 0 mixed.
Replace improperly reused HSTAs
For Bombardier BD-100-1A10 airplanes, the FAA would require replacement of an HSTA if it was reinstalled when it should have been replaced during a required overhaul. That means affected airplanes would need the HSTA removed and a compliant part installed.
Check stabilizer actuator serials
If you operate a Bombardier BD-100-1A10 airplane, the FAA would require verification of the horizontal stabilizer trim actuator (HSTA) serial number. The check is to confirm parts that were supposed to be replaced during an overhaul were not reinstalled.
Ban installation of affected parts
The proposal would prohibit installing affected HSTA parts on Bombardier BD-100-1A10 airplanes under the conditions specified by the FAA. Mechanics and operators would be barred from reinstalling parts the AD identifies as unsafe.

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.

If you fly Airbus Helicopters EC155B or EC155B1 models, listen up! The FAA wants you to swap out your jettisonable windows and seals because they’re harder to open than they should be. Plus, you’ll need to add new labels to keep things safe and clear. This fix helps make sure windows can pop out easily in emergencies, and it’s coming soon to keep everyone flying safe without breaking the bank.
