Analysis

The plt held a commercial certificate, but was a student in helicopter flying. He had over 15,000 hrs total time in airplanes, but only aprx 13 hrs of experience in helicopters. On his 1st solo flt in a helicopter, he was making approaches to a grassy area beside a rwy. On 1 apch, he transitioned from a 60 kt approach to a hover. The approach was made on a heading of 240 deg in variable wind conditions that prevailed from 205 deg at 5 KTS. Reportedly, the plt flared & stopped his forward movement at about 4 ft AGL; however, the nose continued up & started yawing to the right, then the helicopter turned aprx 270 deg to the right & the main rotor blades struck the ground. The plt recalled seeing an indication of 2800 eng RPM before he lost control. A certified flt instructor stated that 2800 RPM was marginal for maintaining directional control.
