The helicopter SE-HVY was being used on 4 October 2005 for inspection of an electrical power line. After completing work for the day the pilot interrupted the return flight at a farm south-west of Lundsbrunn in O county.
He took off at 16:24 with the intention of continuing the flight. The take-off was from a grass field. This was an open area with no obstacles. The weather and visibility were good. There were no known technical problems.
The pilot was in good health. Immediately after take-off a loud bang was heard from the engine, which stopped immediately. The helicopter came down in a field of loose soil. Flames briefly appeared from the engine but the fire did not spread. The helicopter was extensively damaged. The pilot exited unhurt. The engine stoppage was been determined as due to a total failure of the compressor, which in turn led to the breakage of a compressor blade as a result of fatigue. This was very probably initiated by corrosion of
the compressor wheel material.
