Overview

The accident aircraft was manufactured in January 1956. It was originally in service with American Airlines as a freighter until World Airways purchased it sometime after October 1959. At the time of the accident, the aircraft had accumulated 12,746 flight hours.^[2]

The Captain was 46-year-old Rudy J. Holman, who had logged 15,681 flight hours, including 2,548 hours in the DC-6. He had completed a proficiency check in the DC-6 the month before the crash. The first officer was 31-year-old Clayborne P. Claunch, who had logged 6,317 flight hours, including 217 hours in the DC-6. The remaining flight crew consisted of 29-year-old flight engineer Roger E. Davis and 27-year-old navigator Edgar W. Schwoyer.^[2]

Flight

The aircraft took off from Naval Air Station Agana's runway 6L at 6:00 am. The pilot made a right turn during the climbing procedure and collided with Mount Barrigada 50 seconds after takeoff. The aircraft then slid for about 1,000 ft (305 m) into thick underbrush before coming to a stop. 73 of the 86 passengers and 7 of the 8 crew members on board perished. Most of the casualties were caused by a fire that broke out shortly before the aircraft came to a stop.^[2]

Investigation

The Civil Aeronautics Board determined that the crash was caused by the pilot's failure to adhere to standard departure procedures by making a right turn before the aircraft had climbed to 1,000 ft (305 m).^[2]
