Authorities say an American Airlines airplane headed to Reno, Nev., from Chicago returned to O’Hare International Airport when a problem with the fuel feed was detected. No injuries were reported Sunday. Airline spokeswoman Dori Alvarez says flight 1487 departed from O’Hare around 10:40 a.m. The pilot noticed an indicator light showing there was a problem with the plane’s fuel feed. Alvarez says the plane returned after noon as a safety precaution. There were 120 passengers and six crewmembers aboard. The aircraft landed in Reno at 4:08 p.m., four hours later than scheduled. Two other incidents have been reported recently at O’Hare. Chicago Aviation Department officials say a passenger plane slid off the runway on Thursday. A day earlier the wing of a cargo plane taxiing the runway clipped the rudder of an American Eagle flight. No injuries were reported in either incident.
