FAA updates safety rule for Rolls-Royce jet engines not used in US
/ 1 min read
Table of Contents
The Federal Aviation Administration has updated a safety directive for certain Rolls-Royce RB211 Trent 700 series engines. The update incorporates new technical standards from the European Union Aviation Safety Agency to address corrosion fatigue in high-pressure turbine blades. This condition could cause blade cracking, which might lead to aborted takeoffs or engine shutdowns during flight.
Why it matters: This action updates technical requirements to match international safety standards, but it has no immediate impact on US aviation operations. The FAA explicitly states there are no compliance costs because the affected engines are not registered in the United States.
Who it affects
- Owners and operators of Rolls-Royce RB211 Trent 700 series engines with US type certificates (currently none)
This rule was issued by the Federal Aviation Administration and published in the Federal Register; verify details against the original document at regulations.gov under Docket No. FAA-2026-4635 before relying on it.
