What happened
While traveling from Taipei toward Chiayi, the aircraft encountered extremely adverse weather conditions characterized by heavy rainfall and significant turbulence. During the flight, the aircraft entered an uncontrolled descent, eventually crashing into a sugarcane field situated in Yuanlin, approximately 60 kilometers northeast of Chiayi Airport. The impact was so severe that the aircraft disintegrated upon hitting the ground. There were 18 fatalities in the accident, with no survivors reported among the occupants. The passengers included several high-ranking officials from the Taiwan Army who were en route to Chiayi to conduct an inspection of military facilities.
Findings
At the time of the accident, the region was being affected by Typhoon Yancy, which brought the heavy rain and severe turbulence that preceded the uncontrolled descent.
