Pan Am Flight 812, operated by a Pan American World Airways Boeing 707-321B registered N446PA and named Clipper Climax, was a scheduled international flight from Hong Kong to Sydney, Australia, with an intermediate stop at Denpasar, Bali, Indonesia. On April 22, 1974, it crashed into rough mountainous terrain while preparing for a runway 09 approach to Denpasar after a 4-hour 20-minute flight from Hong Kong. The location of the accident is about 42.5 nautical miles (78.7 km) northwest of Ngurah Rai International Airport.
Clipper Climax was the jet used in the 1971 film Willy Wonka & the Chocolate Factory to deliver the guarded shipment of Wonka bars.
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.
