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.”
There are versions of the 777 aircraft with engines built by three different manufacturers. For about the last 15 years, new 777s have all been delivered with GE-made engines. So this recommendation applies to older models of the aircraft still in service.
