Rolls-Royce Engines Get FAA Safety Check Mandate

## Summary

The FAA is rolling out new safety checks for certain Rolls-Royce Trent 1000 engines because a tiny part inside might come loose and cause trouble. Starting January 27, 2026, operators must do regular inspections and possibly take engines out of service if problems show up. This keeps flights safe but means some extra work and costs for airlines using these engines.

## Abstract

The FAA is adopting a new airworthiness directive (AD) for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) Model Trent 1000-A, Trent 1000-AE, Trent 1000-C, Trent 1000-CE, Trent 1000-D, Trent 1000-E, Trent 1000-G, and Trent 1000-H engines. This AD was prompted by a determination made by the manufacturer that a high-pressure compressor (HPC) mini-disc anti-rotation block could possibly release into the HPC assembly stage 5 and 6 discs and the cone rotor rear shaft (HPC rear drum) during an engine operation. This AD requires repetitive borescope inspections (BSIs) of the HPC rear drum cavity and cavities between each HPC rotor disc, and depending on the results of inspection, removal of the engine from service. This AD also allows an alternative method of complying with the repetitive BSIs if certain actions are accomplished. The FAA is issuing this AD to address the unsafe condition on these products.

## Effects PRIA read

- Mandatory inspections for Trent 1000: cost, medium. Operators of certain Rolls‑Royce Trent 1000-A through Trent 1000-H engines must begin repetitive borescope inspections (BSIs) of the high‑pressure compressor (HPC) rear drum cavity and cavities between each HPC rotor disc starting January 27, 2026. If inspections find missing or loose parts, foreig…
- No U.S. compliance cost claimed: benefit, low. The FAA states there are no costs of compliance with this AD for U.S. operators because there are no engines with this type design on the U.S. Registry. The FAA also adopted the AD without prior notice and comment because it concluded no domestic operators use these engines.
- Alternative via engine health monitoring: benefit, low. The AD allows an alternative method of complying with the repetitive BSIs if operators use the Rolls‑Royce engine health monitoring (EHM) service and accomplish all corrective actions within the Rolls‑Royce EHM guidelines. Operators may use that EHM alternative in lieu of the repetitive borescope i…
- No manufacturer reporting requirement: benefit, low. Although the Rolls‑Royce service material asks operators to submit certain information to the manufacturer (including photos and videos), this FAA AD explicitly does not include those reporting requirements. Operators are not required by this AD to submit that information to the manufacturer.
