FAA Orders New Checks on Rolls-Royce Jet Engines
Published Date: 6/15/2026
Rule
Summary
If you operate Rolls-Royce Deutschland Trent 1000 engines, this new FAA rule updates how you check and fix high-pressure turbine blades to keep flights safe. Starting June 30, 2026, you’ll need to do more detailed inspections and possibly replace parts sooner, but there’s also a new option to stop repetitive checks by upgrading parts. These changes might cost some time and money but will help prevent engine problems before they happen.
Analyzed Economic Effects
4 provisions identified: 3 benefits, 1 costs, 0 mixed.
Mandatory HPT Blade Borescope Inspections
If you operate Rolls-Royce Deutschland Trent 1000-AE3, CE3, D3, G3, H3, J3, K3, L3, M3, N3, P3, Q3, or R3 engines, the FAA requires initial and repetitive borescope inspections (BSI) of the high-pressure turbine (HPT) blades for axial cracks beginning June 30, 2026. Depending on BSI results you must either perform additional BSIs or replace the HPT blades, in accordance with EASA AD 2025-0206R1 (incorporated by reference).
Upgrade Option Ends Repetitive Inspections
The AD adds an optional terminating action: operators may install improved HPT blades and an improved combustion rear inner casing bypass case assembly (per the incorporated EASA service material) to stop the repetitive BSI requirement. The improved-part installation is specified in EASA AD 2025-0206R1.
Acceptance-Test Shutdowns Exempted from Some BSIs
The AD excludes certain engines from some borescope inspection requirements if the engine was deliberately shut down and automatically re-started immediately as part of a standard airplane acceptance test. This exclusion is part of the compliance rules incorporated from EASA AD 2025-0206R1 and takes effect June 30, 2026.
No U.S. Compliance Costs (No U.S. Registry Engines)
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. The FAA also notes it found no domestic operators of this product; the AD is still effective June 30, 2026.

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.
2026-15370, Airworthiness Directives; Leonardo S.p.a. Helicopters
The FAA is adopting a new airworthiness directive (AD) for all Leonardo S.p.a. Model AW189 helicopters. This AD was prompted by reports of cracking on the ejector ducts. This AD requires repetitively inspecting the left-hand (LH) side and right-hand (RH) side ejector ducts, including the exhaust bracket reinforcements and reinforcement plates, and, depending on the results, replacing any affected ejector duct. The FAA is issuing this AD to address the unsafe condition on these products.
2026-15455, Airworthiness Directives; Airbus SAS Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A330-200 and A330-300 series airplanes modified by a certain supplemental type certificate (STC). This AD was prompted by a finding that, for airplanes with a flightcrew oxygen system supplied by a single oxygen cylinder, the oxygen supply would not be sufficient under all circumstances for extended operations (ETOPS) with a maximum diversion time of 180 minutes (ETOPS-180) with four flightcrew members. This AD requires revising the existing Airplane Flight Manual Supplement (AFM-S) to limit ETOPS-180 operations to three flightcrew members, as applicable, and correct minimum oxygen dispatch pressure information. The FAA is issuing this AD to address the unsafe condition on these products.
2026-15412, Airworthiness Directives; MHI RJ Aviation ULC (Type Certificate Previously Held by Bombardier, Inc.) Airplanes
The FAA is adopting a new airworthiness directive (AD) for all MHI RJ Aviation ULC Model CL-600-2C10 (Regional Jet Series 700, 701 & 702), CL-600-2C11 (Regional Jet Series 550), CL-600-2D15 (Regional Jet Series 705), and CL-600-2D24 (Regional Jet Series 900) airplanes. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is issuing this AD to address the unsafe condition on these products.

The EPA just made it official: sodium nitrate can be used safely in certain pesticide fumigants without worrying about residue limits! This change mainly helps farmers, food producers, and pesticide makers using sealed warehouse fumigants. The new rule kicks in on June 15, 2026, and saves time and money by cutting red tape on residue testing.
