Accident Details
A Slick Airways Lockheed 1049H, registered N9740Z, crashed and burned during an ILS approach to runway 28R at San Francisco International Airport at approximately 1207 Pacific standard time on February 3, 1963. The aircraft was destroyed by subsequent fire.
Sequence of Events
Due to an inoperative glide slope receiver, the crew was listening to radar advisories on the localizer receiver for altitude information. The aircraft struck approach lights 1,170 feet from the runway threshold, climbed to about 200 feet, and then crashed approximately 1,900 feet beyond the threshold and on the left edge of runway 28L.
Injuries and Damage
Of the three crew members and five passengers aboard, the captain, first officer, and two passengers received fatal injuries. The remaining persons aboard received serious injuries. The aircraft was destroyed by fire.
Probable Cause
The official probable cause, as determined by the Civil Aeronautics Board, was the continuation of an instrument approach after adequate visual reference was lost below authorized minimums. Inadequate monitoring of the instrument approach by the PAR controller was a contributing factor.
