Accident
Flight 812 was a regularly scheduled flight from Hong Kong to Los Angeles via Bali, Sydney, Nadi, and Honolulu. The San Francisco-based cockpit crew consisted of Captain Donald Zinke, First Officer John Schroeder, Third Officer Melvin Pratt, Flight Engineer Timothy Crowley, and Flight Engineer Edward Keating. The Los Angeles-based cabin creHong Kongw were Purser Mary Butterworth, Purser Beverly Schmitt, Flight Attendant Anne Beran, Flight Attendant Janice Fanning, Flight Attendant Ingrid Johansson, and Flight Attendant Donna Kent.
There were 96 passengers from 9 countries on board. 70 passengers were bound for Bali. 24 were bound for Sydney. 2 were bound Nadi.
Flight 812 departed Hong Kong on April 22, 1974, at 1108 UTC. The estimated flying time to Bali was 4 hours and 23 minutes. At 1523 UTC, Flight 812 was on final approach to Bali. The aircraft reported reaching 2,500 ft. Bali Tower gave instructions to continue approach and to report when runway was in sight. Acknowledgement was made by PA812 by saying, "Check inbound". At 1526 the pilot-in-command requested the visibility by calling, "Hey - Tower, what is your visibility out there now?"
However, according to the transcription of Air Traffic Control voice recorder this message was never received by the Bali Tower. Apparently this was the last message transmitted by the aircraft. Bali Tower kept trying to contact the aircraft by calling, "Clipper eight one two, Bali Tower", and "Clipper eight one two, Bali Tower, how do you read", several times. However, no answer was received from the aircraft. It was subsequently found that the aircraft hit a mountain approximately 37 miles northwest of the Bali airport.
Investigation and determination of accident cause
Examination on the disposition of the wreckage and inspection of the site indicated that no structural failure of the aircraft occurred before impact. It was determined that the premature execution of a right-hand turn to join the 263-degree outbound track, which was based on the indication given by only one of the radio direction finders while the other one was still in steady condition, is the most probable cause of the accident.
Nationalities of those on board
Several memorial plaques are to be found for this crash in Jl. Padang Galak, next to the beach Temple, Kesiman, Denpasar East, Indonesia.
