The flight crew of United Airlines Flight No. 368, which took off from O’Hare at 8:53 a.m. and was scheduled to arrive at Orlando International Airport at 12:34 p.m. (Eastern Time), decided to return to O’Hare after the indicator light came on, United spokesman Michael Trevino said.
It wasn’t immediately clear why the light came on or what it indicated, but crews will conduct a mechanical inspection to determine whether the aircraft can return to service, Trevino said.
Passengers will either continue on the aircraft or be accommodated on a replacement aircraft or other flights pending the results of the inspection, Trevino said.
It wasn’t immediately known how many people were aboard the plane, an Airbus A320, but Trevino said that type of aircraft typically carries about 130 passengers.
