On August 29, 2013, at 1643 eastern daylight time, a Brandtly B2B helicopter, N2253U, registered to and operated by the pilot, was substantially damaged when it impacted the ground after takeoff from a private field near Rothbury, Michigan. The commercial pilot and passenger received minor injuries. The personal flight was conducted under the provisions of 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed in the vicinity and no flight plan was filed. The pilot reported that he initiated takeoff in light and variable wind conditions from the middle of a private field. He hover taxied downwind to the east end of the field before commencing the takeoff to the west. During the takeoff, the pilot realized that the helicopter would not clear a tree line located at the edge of the field. He initiated a pedal turn to the left away from the trees to attempt to abort the takeoff. He stated that during the left pedal turn, a gust of wind forced the helicopter toward the ground. The helicopter impacted the ground hard near level attitude on an uphill slope. The main rotor blade struck the ground, the helicopter rolled, and came to rest on its left side. The open field was approximately 750 feet in length (east to west) and 150 feet wide. The field was surrounded by pines trees approximately 30 to 40 feet tall with larger growth on the west end. Performance charts from the helicopter's flight manual indicated that the helicopter should have had the takeoff climb performance to clear the trees during takeoff. Examination of the helicopter by an FAA inspector did not reveal any mechanical anomalies with the flight controls and engine. The pilot reported that the helicopter was operating normally prior to the accident.
