Airlines in the US and Japan have grounded dozens of Boeing 777 aircraft after the dramatic engine failure that United Airlines flight 328 experienced over Denver this weekend. The National Transportation Safety Board’s ongoing investigation says two fan blades on the plane’s number 2 engine had developed fractures.
The Federal Aviation Administration issued an emergency airworthiness directive that requires “immediate or stepped-up inspection of Boeing 777 airplanes equipped with certain Pratt & Whitney PW4000 engines”. The FAA also noted that this was likely to result in aircraft being removed from service.
United Airlines said it is voluntarily grounding 24 Boeing 777 aircraft that use the 4000-series Pratt & Whitney engines.No person was injured in United flight 328, which was bound for Honolulu but safely returned to Denver after encountering the engine failure briefly after takeoff.
