SANTA ANA, Calif. (AP) -- Authorities say an Alaska Airlines plane blew a tire as it landed at John Wayne Airport in Southern California.

Alaska spokeswoman Bobbie Egan says Flight 508 from Seattle, a Boeing 737-800, had already landed safely at the airport in Santa Ana Thursday when air traffic controllers noticed one of its four rear tires was flat.

Egan says the plane stopped on a taxiway while a fire crew inspected the landing gear, but took no action.

There were no injuries.

Airport spokeswoman Jenny Wedge says shuttles took passengers to the terminal.

Egan says the flight's 157 passengers were delayed about an hour. She says the plane was towed to the gate where it is getting an inspection and tire change.

Federal Aviation Administration spokesman Ian Gregor says the agency is investigating.
