On short final during a night visual approach to runway 23 (helipad) at Ringsted (EKRS), the helicopter inadvertently entered IMC and impacted a field northeast of the aerodrome.
Adhering to go-around procedures, the helicopter became airborne again and diverted to EKSE without further incident.
The following causal factors led to a CFIT serious incident:
- A less than optimum pre-flight weather briefing.
- An action plan on flying a shallow approach under VFR conditions with low fog and fog patches.
- Difficulties in assessing height and depth while using NVG.
- Loss of situational awareness due to visual illusions.
- NVG whiteout at low altitude.
