Factual narrative

On April 8, 2006, approximately 1105 mountain daylight time, a Robinson R22 Beta, N921U, collided with the ground in an uncontrolled descent following a loss of control during the takeoff initial climb at Bolinder Field - Tooele Valley Airport, Tooele, Utah. The helicopter, which was registered to Tumbleweed Leasing Company, Inc., of Salt Lake City, Utah, and operated by Upper Limit Aviation of Salt Lake City, sustained substantial damage. The flight instructor and the student pilot were not injured. Visual meteorological conditions prevailed for the instructional flight conducted under 14 CFR Part 91. No flight plan was filed. The helicopter was departing with an intended destination of Salt Lake City when the accident occurred. According to the flight instructor, he and his student had landed at the airport to refuel before continuing their lesson. The wind speed was "17 gusting 24" knots. He restarted the helicopter and hovered to position the ship for takeoff. He began a climb to the southwest with an indicated airspeed of 45 knots. "Upon reaching an altitude of 50-70 feet agl, the aircraft ceased climbing" and "began to be pushed aft and down." He attempted to regain control but was unsuccessful. The helicopter struck the ground in a level attitude, the front of the left skid caught in the soft uneven ground, and the helicopter rolled left. The main rotor blade struck the tail cone, and the helicopter came to rest on its left side. The pilot indicated there was no mechanical malfunction or failure of the helicopter prior to the accident.
