Convair CV-880

JA8030 started a take-off run on runway 33R of Tokyo International Airport under VFR conditions at approximately 1428 hours with the pilot-in-command Manshichi Harano, examinees Yoshiomi Motouchi and Shuji Daikoku, flight engineer Terumitsu Fujimaki, and Chief Examiner of the Civil Aviation Bureau of Ministry of Transport Yukiaki Kawata, on board for the purpose of conducting a practical examination necessary for change in type rating to Convair 880-22M. About the time the aircraft took a nose-up attitude, it began to yaw left and entered into a right side-slip. At approximately 1 500 m from the runway threshold marking, the right main landing gear started to go off the ground, and while the yaw and side-slip further increased, the under-surface of No. 1 engine began to contact the runway at approximately 1 600 m from the marking. The aircraft continued to side-slip with the nose coming down and deviated from the runway at approximately 1 700 m from the marking. The aircraft moved on the lawn area, crossed taxiway C-4, then while proceeding in the direction of approximately 35O left in reference to the runway bearing, moved the heading to approximately 145O left in reference to the runway bearing, thence yawed right and continued the side-slip. Although the aircraft was in a slight nose-up attitude during this period, it went abruptly into a nose-down and almost at that time a fire started near No. 3 engine. During this period the aircraft further proceeded with the left main landing gear, nose landing gear and Nos. 3, 2, 1 and 4 engines separated in this sequence, and came to a stop at a point approximately 2 100 m from runway 33R threshold marking and approximately 200 m from the runway centre line with a heading of 90° in reference to runway 33L. The fire expanded explosively and the aircraft was damaged by fire or burnt except for the aft fuselage, empennage and a portion of the main wings. All five persons on board died. The flight was performed on behalf of Japan Air Lines.

Upon landing, the right main gear collapsed and the airplane sank on its belly and came to rest. There were no casualties but the aircraft was damaged beyond repair.

While cruising at an altitude of 2,200 meters in marginal weather conditions, the airplane struck the slope of Mt Nakanoone located some 65 km northeast of Hamamatsu. SAR operations were conducted but eventually suspended few days as no trace of the aircraft nor the crew was found. The wreckage was found on 29 December 1966 in an isolated area. Both pilots were killed.
