FAA Moves to Ground Risky Rolls-Royce Engine Pumps
Published Date: 5/20/2026
Proposed Rule
Summary
The FAA wants to make sure Rolls-Royce Trent7000-72 and Trent7000-72C engines stay safe by stopping certain lubrication pumps from being installed unless they meet new rules. This comes after some engines shut down mid-flight because parts failed too soon. If you own or work with these engines, you’ll need to follow these new rules soon, but no big costs are expected.
Analyzed Economic Effects
5 provisions identified: 1 benefits, 4 costs, 0 mixed.
Potential high on‑condition screening cost
If screening tests are needed based on verification results, the FAA estimates the screening takes 4 work-hours (4 x $85 = $340 labor) and identifies parts costs shown as $33,320. The FAA cannot predict how many engines will require these screening tests.
Ban on installing pumps without criteria
The AD would prohibit installing certain lubrication/scavenge oil pumps unless the installation criteria in the manufacturer's NMSB (as required by EASA AD 2024-0029) are met. The AD replaces language that previously allowed installation with a strict 'do not install' requirement.
Which engines are covered
This proposed rule applies to all Rolls‑Royce Deutschland Model Trent7000-72 and Trent7000-72C engines. If you own or operate these engines, the AD would apply to your equipment.
Per‑installation verification cost estimate
The FAA estimates verifying the installation criteria before each affected pump installation will take 0.5 work-hours at $85 per hour, costing $42.50 per pump installation. The FAA estimates this AD would affect 98 engines on U.S. registry, for a total estimated cost of $4,165 for that verification work across those engines.
FAA finds no significant small‑entity impact
The FAA certifies that this proposed AD would not have a significant economic impact, positive or negative, on a substantial number of small entities under the Regulatory Flexibility Act.

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.

Previous: 2026-10047, Airworthiness Directives; Airbus SAS Airplanes
The FAA wants all Airbus A330-841 and A330-941 airplanes to get regular checks for cracks on certain wing parts to keep flights safe. If cracks are found, fixes must be done right away. Comments on this plan are open until July 6, 2026, and these inspections might cost airlines some time and money but will help prevent bigger problems.
Next: 2026-10082, Increasing the Fee for Certain Aliens Ordered Removed in Absentia as Established by the HR-1 Reconciliation Bill
The government plans to raise the fee from $5,130 to $18,000 for certain people who were ordered to leave the U.S. but didn’t and got caught later. This change affects those removed in absentia and includes yearly inflation updates to keep the fee current. Comments on this proposal are open until June 22, 2026, so now’s the time to speak up!
