While the National Transportation Safety Board investigates an aircraft engine failure that occurred in flight on Saturday, manufacturer Boeing has recommended that airlines suspend flying certain versions of the 777 wide-body airliner.
“Boeing is actively monitoring recent events related to United Airlines Flight 328,” the company stated on Sunday. “While the NTSB investigation is ongoing, we recommended suspending operations of the 69 in-service and 59 in-storage 777s powered by Pratt & Whitney 4000-112 engines until the FAA identifies the appropriate inspection protocol.”
