Circumstances:
The crew was performing a flight from Clark AFB in Manila to Tachikawa AFB in Tokyo with an intermediate stop in Kadena AFB, Okinawa. On the second leg, while approaching Tachikawa AFB by night, the crew encountered poor weather conditions with low clouds and rain falls. While descending to an altitude of 5,000 feet, the four engine aircraft hit the slope of the Mt Hirugatake (1,279 meters high) located 34 km southwest of the Tachikawa AFB. The aircraft was destroyed by impact forces and all 35 occupants were killed.
Probable cause:
While approaching Tachikawa AFB, the crew reported his position over the O-Shama radio range station at an altitude of 5,000 feet. Probably due to a navigation error, the aircraft was in reality 40 km more south of this position.

Circumstances:
The aircraft was performing a flight from Seoul-Kimpo to Tachikawa AFB with several US officers and five civilians on board. While approaching the Tokyo area by night and from the southwest, the crew completed a turn at an altitude of 1,500 meters in marginal weather conditions when the aircraft hit the slope of a mountain located west of the city of Atsugi, about 30 km southwest of Tachikawa AFB. The aircraft was destroyed by impact forces and burned completely. All 41 occupants were killed. At the time of the accident, the visibility was 10 km with cumulus and altostratus between 1,000 and 2,500 meters.
Probable cause:
Apparently following an inappropriate flight planing, or maybe due to a lack of concentration or situational awareness, the crew did not check their instruments properly and failed to recognize that they were following a wrong heading to land at Tachikawa AFB. It is possible that strong winds (up to 40 knots at the time of the accident) may contribute to the deviation of the approach path.
