A Japan Airlines flight from Chicago made a safe emergency landing at Narita International Airport Tuesday after reporting suspected trouble with its main landing gear.
According to the transport ministry's office at the airport, no injuries were reported among the 232 passengers and crew on the Boeing 777, which landed at around 8:15 p.m. Tuesday.
The aircraft declared an emergency after it departed Chicago O'Hare International Airport Tuesday morning Japan time, and the airport reported to JAL that a sensor component of the gear was found on the runway.
After the aircraft landed at Narita, the runway was closed for about 10 minutes for inspection.
Japanese media reports said, quoting JAL officials, that a box-shaped component that contains sensors to show conditions of the automatic braking system and tire conditions on an instrument panel was missing.
The aircraft might have struck a chunk of ice, since there was snow on the runway at the time of takeoff, the officials reportedly said.
