The NTSB's narrative final · quoted from the NTSB record
The pilot was approaching to land in his homebuilt helicopter. He was applying maximum power, but did not have sufficient rotor RPM. In an attempt to increase RPM, he lowered the collective, causing the helicopter to undershoot the intended landing point. The pilot could not touchdown at this point, because the field was at a 9 to 10 degree slope angle. Additionally, he did not have enough rotor RPM to hover up-slope. He made a 180 degree turn and flew down-slope. After the turn, the forward momentum plus the 1 to 2 knot headwind slightly increased rotor RPM. However, the pilot still did not have enough power to hover. He decided to perform a slide-on landing. During the landing, the right skid struck a mound of dirt, causing the helicopter to roll left. The main rotor blades struck the ground and tailboom. On July 22, 1999, the engine was inspected and operated at the manufacturer's facility. No interruptions, abnormalities, or discrepancies were found. The pilot reported a total flight experience of 110.5 hours, which 98.5 hours were in the accident helicopter. He received his private pilot license on December 4, 1998.
