|Executive Summary:||A Trans World Airlines, Inc., Boeing 707-331C, crashed into San Francisco Bay at approximately 2243 Pacific daylight time, September 13, 1972, following a rejected takeoff frcm Runway 0LR at the San Francisco International Airport, San Francisco, California. Flight 604 was a regularly scheduled cargo flight from San Francisco, California, to the John F. Kennedy International Airport, Jamaica, New York. There were no injuries to the three crewmembers, the only persons on board. The aircraft was substantially damaged.|
The investigation disclosed that the aircraft failed to stop on the remaining runway following a rejected takeof initiated by the captain. This action was taken after the takeoff roll had traversed approximately half the 9,500-foot runway to the vicinity of the intersections of Runvay 01R vith parallel Runways 28L and 28R. The action was initiated vhen the crew detected an aircraft vibration and a reduction in aircraft acceleration, after passing V1 speed. Crew action included the use of wheel braking, spoiler operation, and reverse engine thrust. However, the aircraft overran the departure end of the runway and a breakwater and came to rest in San Francisco Bay, approximately 50 feet from the shoreline.
Following the accident,, numerous pieces of tire tread and shredded tire casings from the disintegrated No. 3 and No. 4 rear tires were found along the runway. Dual wheel rim marks from these wheels were also evident.
The National Transportation Safety Board determines that the probable cause of this accident was the initiation of rejected takeoff procedures, beyond V1 speed, with insufficient runway remaining In which to stop the aircraft. The crew action was prompted by the failure of the two right truck rear tires which produced a noticeable aircraft vibration and a reduction in aircraft acceleration.
As a result of the investigation of this accident, the Safety Board recanmends reconsideration of recommendations previously made to the Federal Aviation Administration.
