Signs of material fatigue were found by researchers on a fan blade of the Boeing 777 engine, which ignited above Colorado on a United Airlines aircraft.
Flight 328 managed to land at Denver Airport, after the right engine crashed into houses, fortunately without any casualties.
Following the crash, Boeing recommended that all its Pratt & Whitney PW4000 aircraft be discontinued, and that the 128 Boeing 777s around the world, which are fleets of American United Airlines, Japanese ANA and JAL, as well as Korean Asiana Airlines. The US National Transportation and Security Administration (NTSB) announced late yesterday that two fan blades of a Boeing engine had broken. One of them shows signs of fatigue of its metal construction material and the inspectors believe that it detached and broke the second fin. The President of the NTSB, Robert Schumbalt, said that the two blades will be transported to a laboratory of the construction company Pratt & Whitney where they will be thoroughly studied by security inspectors of his service. “Our mission is to understand what and why it happened, so that it does not happen again in the future,” he said.
The United Airlines Boeing 777 was carrying 231 passengers to Honolulu when its right engine was damaged, with passengers describing a “big explosion” shortly after take-off and noting that the aircraft was shaking violently and losing altitude. Fortunately, he managed to return to Denver Airport, although engine wreckage was found in a residential area in the nearby town of Bromfield. On the same day as the accident in Denver, a similar incident occurred in a town in the south of the Netherlands, where two people were slightly injured on the ground by the wreckage of a Boeing 747 400 cargo aircraft.

Pieces of engine blades apparently fell in the town of Meersen, and one of them was nailed to a car. The plane, which had taken off from Maastricht bound for New York, landed safely in Liege, Belgium.
