Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Engines
Published Date: 7/2/2026
Rule
Summary
If you own certain Rolls-Royce Deutschland Trent XWB engines, this new rule means you’ll need to check the main fuel hose more often for cracks, dents, or wear. Some engines require one-time inspections, while others need regular check-ups to keep flying safely. These changes start July 17, 2026, and could mean some repair costs if parts need replacing.
Analyzed Economic Effects
7 provisions identified: 6 benefits, 1 costs, 0 mixed.
One-time inspections required
If you own certain Rolls‑Royce Deutschland Trent XWB engines, you must do a one-time on-wing visual and dimensional inspection of the main fuel hose assembly to check for softness, shrinkage, cracks, chafing, dents, kinks, necking, and degradation of the hose braid wire, and replace the main fuel hose assembly if necessary. The requirement is imposed through incorporation of EASA AD 2025-0128R1 and is effective July 17, 2026.
Repetitive inspections for other engines
For certain other Rolls‑Royce Trent XWB engines, the rule requires on-wing and in-shop repetitive visual and dimensional inspections of the main fuel hose assembly to check for softness, shrinkage, cracks, chafing, dents, kinks, necking, and degradation of the hose braid wire, and replacement of the main fuel hose assembly if necessary. These repetitive inspections are required as specified in EASA AD 2025-0128R1 incorporated by reference, effective July 17, 2026.
Optional terminating action available
The incorporated EASA AD provides an optional terminating action for the repetitive inspections: the repetitive checks end if the engine has passed an inspection with no findings (or findings are corrected) or if the engine has not yet reached the inspection threshold. That optional terminating action is part of the compliance material incorporated as of July 17, 2026.
Applicability expanded to more models
The AD expands applicability to include certain Rolls‑Royce Deutschland Model Trent XWB-75, Trent XWB-79, Trent XWB-79B, and Trent XWB-84 engines in addition to Trent XWB-97 engines, as identified in EASA AD 2025-0128R1. This expanded applicability is effective July 17, 2026.
No reporting requirement to manufacturer
Although EASA AD 2025-0128R1 specifies submitting certain inspection information to the manufacturer, this FAA AD does not include that reporting requirement. The FAA made this exception in the regulatory text effective July 17, 2026.
Installation allowed if serviceable and inspected
EASA AD 2025-0128R1 (incorporated by reference) allows installing an affected part on any airplane if the part is serviceable, and allows installing an affected engine if the engine passed the required inspections or findings were corrected. The FAA AD incorporates that material (with limited exceptions) effective July 17, 2026.
No U.S. compliance costs asserted
The FAA states there are no costs of compliance with this AD because there are no engines with this type certificate on the U.S. Registry. That statement appears in the Costs of Compliance section of the AD.

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.
