FAA Orders Fix for Leaky Jet Engine Pumps
Published Date: 6/3/2026
Proposed Rule
Summary
The FAA wants to fix a fuel leak problem in certain General Electric GEnx engines by making airlines replace the main fuel pump with a safer part. This affects many big airplane engines and aims to keep flights safe and smooth. Comments on this plan are open until July 20, 2026, and swapping parts might cost some money but prevents bigger issues down the runway.
Analyzed Economic Effects
1 provisions identified: 0 benefits, 1 costs, 0 mixed.
Airlines Must Replace Defective Fuel Pumps
Operators of airplanes with the listed GE GEnx engines must remove from service certain main fuel pumps and replace them at the next engine shop visit after the AD's effective date to prevent a fuel leak that could cause an uncontrolled engine fire. The FAA estimates this proposed AD would affect 265 engines on U.S. registry; replacing with an overhauled pump is estimated at $25,337 per engine (8 work‑hours at $85/hour plus $24,657 parts), while a new main fuel pump would cost about $607,255. Comments on the proposal are due by July 20, 2026.

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.
2026-18376, Airworthiness Directives; Bombardier, Inc. Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-2A12 airplanes. This proposed AD was prompted by reports of fuel leakage near rib 6 during production pressure testing. An investigation found oversized holes in a certain outboard shear-tie. This proposed AD would require an inspection of the fasteners and fastener holes at rib 6 for discrepancies and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.
2026-18375, Airworthiness Directives; Airbus SAS Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 and A350-1041 airplanes. This proposed AD was prompted by reports of failure of hydraulic engine driven pumps (EDPs) of the standard EDP-06. This proposed AD would require, depending on airplane configuration, modifying the hydraulic monitoring and control application (HMCA), accomplishing applicable concurrent requirements, revising the existing airplane flight manual (AFM), and replacing affected parts. This proposed AD would also prohibit the installation of affected parts and prohibit the installation of certain HMCA software. The FAA is proposing this AD to address the unsafe condition on these products.
