After the fire was extinguished, control was secured, and the situation evaluated, the crew elected to proceed to Travis Air Force Base, California. They stated this decision was based on a partial hydraulic failure and the uninhabited approaches to Travis, plus the availability of military firefighting equipment and a longer runway.
After lowering the landing gear by emergency means, the flight landed at Travis at 1434 without further difficulty. Passengers evacuated the aircraft using the inflated emergency slides because no stairs were available.
The accident occurred about 1-1/2 miles west of the departure end of runway 28L at San Francisco International Airport, San Francisco, California, at an altitude estimated to be 800 feet m.s.l. The accident occurred during daylight hours.
