Based on a preliminary investigation of the helicopter’s two flight data recorders, mechanical failure could be 80 percent ruled out as the cause, while weather, including elements such as turbulence and wind shear, could be 80 to 90 percent excluded, the official said. However, the flight recorders contain a memory card that can only be decoded by the aircraft’s US-based manufacturer, they said. Eight, including Chief of the General Staff General Shen Yi-ming (沈一鳴), died in the crash. Military investigators extracted the flight recorders at about 10:40am the following day. Political Warfare Bureau staff officer Lieutenant Colonel Lee Chun-feng (李均峰) said that he had just been promoted by Yu and reported to the bureau on the day of the accident.
