OAKLAND, Calif. — Maintenance crews will inspect a Southwest Airlines jet that made an emergency landing at Oakland International Airport when the pilot received warning of an engine fire.

Southwest Airlines spokesman Brad Hawkins said the Los Angeles-bound flight landed safely in Oakland minutes after taking off from San Francisco International Airport around 9 p.m. Friday.

As the plane was ascending, a warning siren indicated there was a fire in one of the plane's engines. Hawkins said the pilot shut the engine down and diverted to Oakland.

None of the 108 passengers and five crew members aboard was injured. The passengers were put on another flight and arrived in Los Angeles before midnight.

Hawkins said crews on Saturday will try to determine whether there was a fire, and if so, what caused it.

Southwest is based in Dallas.
