What happened
During a scheduled training mission originating in Phuket and bound for Ranong, an aircraft impacted a mountain slope. The incident occurred approximately 48 km south of Ranong. At the time of the accident, the flight crew was performing a descent toward Ranong Airport amidst unfavorable weather conditions.
Findings
Investigations into the crash indicate that the crew did not maintain a sufficient altitude during the approach. This failure to monitor the aircraft's vertical position relative to the terrain led to the impact with the mountainside. The accident resulted in two fatalities, as both pilots on board were killed in the collision.
