FAA Hits Pause on Engine Fix After Finding Even More Problems
Published Date: 5/29/2026
Proposed Rule
Summary
The FAA is hitting pause on a rule that would have made Rolls-Royce Deutschland RB211 Trent engines replace certain low-pressure compressor blades because more blades might be affected than first thought. This means owners and operators of these engines won’t have to act just yet while the FAA digs deeper. Keep an eye out—new rules could pop up once the FAA finishes its review, possibly affecting maintenance schedules and costs.
Analyzed Economic Effects
3 provisions identified: 1 benefits, 1 costs, 1 mixed.
Compliance Delay for RB211 Trent Blades
As of May 29, 2026, the FAA withdrew the September 15, 2025 NPRM that would have required removal and replacement of affected low-pressure compressor (LPC) blades on Rolls‑Royce Deutschland RB211 Trent 768-60, 772-60, and 772B-60 engines. Owners and operators of those engines are not required to comply with that NPRM while the FAA evaluates the issue.
EASA Added Nine Blade Serial Numbers
EASA superseded its earlier AD and issued EASA AD 2025-0288 on December 17, 2025, which expands the list of affected LPC blades by adding nine additional serial numbers. The FAA is evaluating that expanded list and may pursue further rulemaking.
Regulatory Uncertainty Continues
The FAA withdrew the NPRM because it did not address all affected LPC blades and stated the withdrawal does not preclude further rulemaking. That means owners/operators face ongoing uncertainty about future maintenance mandates and schedules.

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.
2026-10802 — Airworthiness Directives; Airbus SAS Airplanes
If you fly or work with certain Airbus A330 planes, listen up! The FAA found a production mistake affecting the windshield frames and now requires regular detailed inspections and fixes to keep everyone safe. These new rules kick in July 6, 2026, so airlines should prepare for some extra checks that might cost time and money but keep flights secure.
2026-10801 — Airworthiness Directives; Airbus SAS Airplanes
The FAA is making a new rule for certain Airbus A318, A319, A320, and A321 airplanes because some bolts in seat rails have been breaking. Airlines must swap out nylon bushes for stronger bronze ones and can’t use the old parts anymore. This fix starts July 6, 2026, keeping passengers safer without breaking the bank.
2026-10800 — Airworthiness Directives; Airbus SAS Airplanes
The FAA is rolling out new safety rules for many Airbus A319, A320, and A321 airplanes because extra weight from rudder repainting or repairs might cause stability problems. Airlines must check for airframe vibrations after any vibration event, report what they find, and fix issues if needed. These rules kick in on June 15, 2026, and could mean some extra work and costs for operators to keep flights safe.
2026-10806 — Airworthiness Directives; Goodrich Cabin Attendant Seats
The FAA is making sure certain Goodrich cabin attendant seats on Airbus A330 and A340 planes are safe by requiring airlines to replace some faulty seat parts and update their labels. This fix starts July 6, 2026, and helps prevent seat problems during flights. Airlines will need to spend time and money swapping out the parts to keep everyone safe and comfy.
2026-10799 — Airworthiness Directives; Airbus SAS Airplanes
The FAA is rolling out new safety checks for certain Airbus A318, A319, A320, and A321 airplanes because some fasteners might not have been made quite right. Starting July 6, 2026, airlines must do special inspections regularly to catch any issues early and fix them if needed. This keeps flights safe but might mean some extra maintenance time and costs for operators.
