Twenty-four United Airlines planes were grounded shortly after takeoff

February 22, Kathmandu - United Airlines has grounded 24 of its planes after an engine problem caused a fire, and part of it crashed shortly after takeoff.

The Boeing 777 took off from Denver on Saturday after an engine problem caused a fire. Since then, 24 aircraft of that version have been grounded, according to United Airlines.

The plane, carrying 231 passengers and 10 crew members, made an emergency landing at Denver airport after a fire broke out in its engine. Everyone on the plane was safe. The wreckage of the plane fell into the garden of a Broomfield resident's home.

Following the incident, Japan has asked airlines using Boeing 777 aircraft not to use its airspace.

The Federal Aviation Administration (FAA) has stated that the engine of the right-wing of the United Air flight from Denver to Honolulu had a problem.

The AFA has ordered further testing of the Boeing 777 with Pratt & Whitney 4,000 engines. The FAA is also preparing to hold discussions with representatives of the engine manufacturer and Boeing.
