Due to continued problems with the Rolls Royce Trent 1000 and reliability for the both engines to not shut down mid flight is expected to result in the FAA. Reducing the ETOPS time of aircraft operating with tye Trent 1000 from 330 minutes to 140 minutes. This is expected to reduce route capabilities for airlines using their 787s with the Trent 1000. Rolls Royce is also continuing to struggle with accelerated agin problems on their Trent 1000s still and has resulted in a major backlog of engine deliveries for the type.
"The U.S. Federal Aviation Administration (FAA) plans to reduce the amount of time the affected planes can fly on a single engine after a failure of the other. The time limit would drop as low as 140 minutes, compared with the current window of 330 minutes, a source familiar with the plans said.
This effectively curtails operations across oceans or remote areas."
Overall this is not good for anyone, especially the airlines that use the Trent 1000 on their 787s, both the ones to be delivered still or already operating. The FAA announcement will surely rollback the operations of airlines like ANA who have a large amount of 787s running on Trent 1000s and the problem still does not look close to being rectified. In addition, this will be a major hit to RR’s reputation in the future for their engines as GE’s GEnx’s are not facing such a major and prolonged reliability problem.
