United Airlines temporarily grounds 24 planes following catastrophic engine failure over Denver
Quote:
United Airlines said Sunday that it will “voluntarily and temporarily” ground 24 aircraft powered by a certain type of engine after one of its planes suffered a catastrophic engine failure over Denver on Saturday.
The decision comes as federal aviation regulators appear to be zeroing in on the jet’s fan blades as a culprit for the drama that played out in Colorado’s skies and in the northwest Denver metro area.
The aircraft that are being removed from United’s service have Pratt & Whitney 4000 series engines. The line of engines is used on many popular, large aircraft types, including the Boeing 747-400, Boeing 777, Boeing 767 and Airbus A330.
United, which has a hub at Denver International Airport, said the aircraft that are being grounded are Boeing 777’s.
The National Transportation Safety Board is investigating. It said Sunday that its preliminary investigation revealed:
One fan blade was fractured near the root
An adjacent fan blade was fractured about mid-span
A portion of one blade was imbedded in the containment ring
The Federal Aviation Administration on Sunday said it would require immediate, stepped-up inspections of Boeing 777 airplanes equipped with Pratt & Whitney 4000 series engines. It’s likely, the agency said, that planes will be removed from service as a result.
