Rolls-Royce Engines Get FAA Safety Check Mandate

Published Date: 1/12/2026

Rule

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.

Analyzed Economic Effects

4 provisions identified: 3 benefits, 1 costs, 0 mixed.

Mandatory inspections for Trent 1000

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, foreign objects, scoring, or impact damage, the engine must be removed from service.

No U.S. compliance cost claimed

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

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 inspections specified in the service material.

No manufacturer reporting requirement

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.
