The helicopter was on a survey mission to collect water samples from lake Tyresö-Flaten. The pilot misjudged the altitude with the reflecting sun in the lake surface. The helicopter made contact with the water and tipped on its side resulting in the main rotor hitting the water. It was equipped with emergency floats and remained afloat upside down.
The pilot and passenger were not injured and were helped by school kids who were out canoeing on the lake.
The accident investigation authority writes that there was no method described in the operations manual for approach and height reduction towards a water surface in calm conditions without the support of other references or aids. This probably contributed to control over the closing speed and distance to the water surface having been lost, which resulted in collision with the water surface. The rescue operation for the accident in question functioned according to the areas of responsibility and procedures applicable for this operation. The report contains no recommendations.
