What happened
During an approach to Matsu Nangan Airport, the flight crew encountered heavy fog that significantly reduced visibility. Although the aircraft was operating under Visual Flight Rules (VFR), the conditions had transitioned into Instrument Meteorological Conditions (IMC). The pilot-in-command proceeded with the approach without establishing visual contact with the runway.
As the aircraft reached the final stage of the approach, the crew attempted to execute a go-around maneuver. However, the decision to abort the landing was made too late to avoid an impact. The aircraft struck the water surface and crashed in the sea at a distance of roughly 1,600 meters from the shore. The accident resulted in six fatalities and left 11 injuries among the occupants.
Findings
Investigations into the event indicate that the pilot-in-command continued the approach despite the lack of visual references to the runway. Furthermore, the crew failed to properly monitor the onboard instruments during the descent. The primary contributing factor was the failure to maintain proper instrument monitoring and the decision to continue the approach without visual contact with the landing area.
