The aircraft was destroyed in the accident, while all 37 occupants of the flight were killed. An investigation of the accident by the Japanese government aircraft accident investigation committee was hampered by the
occupation authorities due to their refusal to provide a
tape recording of the conversations between the
ATC at
Haneda Airport and Flight 301. Alongside the fact that flight 301 was not equipped with either a
cockpit voice recorder or a
flight data recorder, the exact cause of the crash could not be determined. The committee proposed that the only evidence they had, which was that the aircraft had deviated from its original course, suggested that the cause of the accident was due to a
navigational error by the pilots of flight 301. == References ==
