SEATAC, Wash. - An American Airlines jet with 151 passengers and six crew members aboard caught fire at Sea-Tac Airport on Wednesday morning as it was taxiing toward the runway.

The jetliner, Flight 728, was destined for Philadelphia when a controller warned the pilot about the fire.

Sea-Tac Airport fire crews put out the flames on the tarmac. There were no injuries.

Recordings from the air-traffic control tower at airport include a controller telling the plane's pilot that flames are coming out of the rear of the airplane.

American Airlines later released a statement saying that the fire was in the airliner's auxiliary power unit.

"Prior to departure from Seattle, American Airlines flight 728 experienced a mechanical issue with the auxiliary power unit (APU)," the airline statement said. "The Port of Seattle Fire Department responded after flames were reported from the APU exhaust. Once the aircraft was cleared, the Airbus A320 taxied back to the gate. Our maintenance team is currently inspecting the APU. We apologize to our passengers for the inconvenience."
