Location:Orremossen in Vättlefjäll -   Sweden
Phase: En route
Departure airport:Alingsås
Destination airport:Göteborg
At about half-past-one the pilot took off from Alingsås for Göteborg. The course was initially directly towards Göteborg at an altitude of approximately 1000 ft above sea level. As he approached Vättlefjäll, north-east of Göteborg where the terrain is hilly and somewhat higher, he started to turn in various directions and to fly in circles. About 16 minutes after takeoff the pilot contacted Säve tower and asked about the weather. He also stated that he was going to attempt to fly through a patch of rainy weather.
A witness who heard the helicopter flying around in the area heard a report about 9 minutes later, whereafter the noise of the helicopter suddenly ceased.
The course of events, the crash site, the helicopter wreckage and the technical investigation indicate that the pilot involuntarily came into cloud and then lost control of the helicopter. The helicopter then entered an uncontrolled state which caused the main rotor, through some form of mastbumping, to strike the forward portion of the helicopter before the latter struck the ground.
The accident was caused by the rapid deterioration of the weather during the flight and the pilot's failure to realise in time that there was thus no possibility to complete the planned flight in view of the weather, terrain, the helicopter's equipment and his own flying experience.
