Additional inspections of Boeing Co’s 777 jets using the same sort of engine that shed debris over Denver on Saturday were confirmed by United States aviation regulators, while Japan went further and suspended their use while deciding what action to take.
After a United Airlines 777 returned safely to Denver International Airport on Saturday after its right engine failed, the regulatory moves involving aircraft with Pratt & Whitney 4000 engines arrived.
The incident on United Airlines Flight 328 from Denver to Honolulu, with 231 passengers and 10 crew members, took place shortly after it took off. Back in Denver, the plane landed safely.
United said on Sunday it would withdraw its 24 operating aircraft of the same type from its schedule voluntarily and temporarily.
In Broomfield, Colorado, photos posted by police showed substantial aircraft debris on the property, including an engine cowling littered outside a home and what appeared to be other parts of a field.
In its initial review of the plane, the National Transportation Safety Board (NTSB) reported that much of the damage was limited to the right engine, with only minimal damage to the rest of the aircraft.
The inlet and casing were removed from the engine and two fan blades were fractured, while damage was reported to the remaining fan blades.
