Bombardier Wings Too Cozy? FAA Demands Spacer Checks Now
Published Date: 10/14/2026
Rule
Summary
The FAA is fixing a safety issue on certain Bombardier BD-700-2A12 airplanes where parts in the right wing are too close together, which could cause problems. Starting November 18, 2026, owners must check and fix these tight spots between fuel lines, hydraulic systems, and vent tubes to keep flights safe. This update helps prevent potential damage and keeps the planes flying smoothly without unexpected costs.
Analyzed Economic Effects
5 provisions identified: 3 benefits, 2 costs, 0 mixed.
Required wing inspections and fixes
You must inspect and fix low-clearance areas in the right wing of Bombardier BD-700-2A12 airplanes: between the fuel line flexible coupling and the harness support bracket clip-nut in bay 3, between the fuel line flexible coupling and hydraulic system 3 line in bay 18, and inspect clearance between hydraulic system 3 lines and the fuel vent tube in bay 20. Required actions include replacing the clip-nut, replacing fuel tube assemblies between rib 17 and rib 20, and doing on-condition work such as replacing hydraulic system support brackets between rib 19 and rib 21; the FAA estimates the basic required actions cost $2,693 per airplane (9 work-hours at $85/hour plus $1,928 parts).
Manufacturer warranty may cover some costs
The FAA notes the manufacturer has indicated that some or all costs of compliance with this AD may be covered under warranty, which could reduce the cost impact for affected operators. The FAA's cost estimates do not assume warranty coverage but acknowledge warranty could lower out-of-pocket expenses.
Compliance deadline: November 18, 2026
The AD becomes effective on November 18, 2026, and affected Bombardier BD-700-2A12 airplane owners/operators must comply with the AD's required actions and compliance times as of that date. The FAA incorporated Transport Canada AD CF-2025-49 by reference and substituted this AD's effective date where the Transport Canada AD refers to its own effective date.
No FAA reporting requirement to manufacturer
Although Transport Canada AD CF-2025-49 calls for submitting certain information to the manufacturer, this FAA AD explicitly does not include any requirement to submit that information to the manufacturer. You are not required by this FAA AD to report those items to the manufacturer.
Operators may do work earlier or voluntarily adopt measures
Operators are permitted to accomplish the AD requirements earlier than the specified compliance times or to voluntarily adopt manufacturer service information, operational limitations, or additional inspections. The FAA did not mandate interim actions but allows earlier voluntary actions if operators choose to mitigate risk sooner.

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.
