Officials of Republic Airlines say no passengers were seriously injured when the pilot of a flight from Washington, D.C., ordered the plane be evacuated after landing at Chicago's O'Hare International Airport.
Republic Flight 4309 was operating as an American Eagle flight when it landed safely Monday.
Airline officials say the pilot made the decision to evacuate the Embraer 175 aircraft due to an instrument warning of a possible issue.
The passengers left the plane via chutes. The airline said 57 passengers and four crew members were aboard the flight.
