What happened
The pilot was conducting an arrival procedure during nighttime conditions. The weather report indicated calm wind conditions at the time of the event. The flight crew initiated an approach to Runway 30, which was equipped with operating medium intensity lighting systems.
As the aircraft established itself on the final approach segment, the pilot allowed the airspeed to decrease below safe limits. This loss of airspeed resulted in a stall. The aircraft subsequently struck the ground approximately 300 feet short of the runway threshold.
The investigation
The investigation focused on the operational parameters leading up to the impact. Key factors included the nighttime visibility environment and the status of the runway lighting, which was confirmed to be functional. No mechanical anomalies were cited as contributing factors in the provided narrative.
Findings
The primary factor leading to the accident was the pilot's failure to maintain adequate airspeed during the final approach phase. The stall occurred due to this low-energy state, resulting in a controlled flight into terrain just prior to the intended landing point.
