Analysis

The helicopter was in flyable storage & was on a weekly flight to operate the various systems. After landing on soft terrain, the plt started to takeoff. As the helicopter lifted off, it rolled over & the main rotor blades struck the surface. Subsequently, the main rotor system & transmission separated from the acft. An exam revealed no preimpact failures. The terrain consisted of mowed sod with black soil underneath. The sufface was soft. Two deep ruts were found at the site with additional ruts (from the skids) nearby.
