What happened
During an ascent following departure from Hualien Airport, the aircraft encountered intense atmospheric instability caused by active thunderstorms. While navigating through this heavy weather, the plane experienced extreme turbulence that resulted in a loss of stability. The aircraft subsequently entered an uncontrolled descent and struck a cliffside located approximately 12 km away from the airport.
There were two fatalities resulting from the impact, as both individuals on board perished in the accident.
Findings
Investigation into the crash determined that the primary factor was the encounter with severe turbulence within a thunderstorm environment. This weather condition led to the loss of control of the aircraft during the climb phase.
