En route from Taipei to Saigon, the airplane encountered poor weather conditions and crashed into the South China Sea. SAR operations were conducted but eventually abandoned few days later as no trace of the aircraft nor the 10 occupants was found. At the time of the accident, weather conditions were poor due to typhoon 'Bess'.
Probable cause (official findings): Due to lack of evidences as the aircraft was not found, the exact cause of the accident could not be determined.
