Rolls-Royce jet engines need more frequent checks for critical parts

US aviation regulators just ordered operators of certain Rolls-Royce jet engines to perform more frequent and stricter maintenance. This means airlines using these engines will have higher costs and potentially more downtime for inspections and part replacements.

Airlines operating these specific Rolls-Royce engines will now spend more money and time keeping them in service. The new rules mean critical engine parts must be inspected or replaced sooner than before, reducing the risk of engine failure.
