Incident
On approach to Matsu Nangan Airport, the crew encountered poor weather conditions with reduced visibility due to fog. The descent was completed under visual flight rules (VFR) mode in instrument meteorological conditions (IMC). On final approach, the copilot, who was the pilot-in-command, continued the approach despite not having established any visual contact with the runway and failed to monitor the instruments. The crew eventually attempted a go-around, but this decision was made too late. The aircraft struck the water surface and crashed into the sea approximately 1,600 meters offshore. Six passengers were killed, while 11 other occupants were injured.
Investigation
An investigation into the accident was conducted. The official findings identified the probable cause.
Probable Cause
The official probable cause states: Wrong approach configuration on part of the crew who continued the descent under VFR mode in IMC conditions, below the minimum descent altitude (MDA) until the aircraft struck the water surface. Poor supervision on part of the captain. Poor crew coordination and poor approach and landing planning.
