On October 24, 2007, about 1345 central standard time, a single-engine Robinson R-44 helicopter, N744RG, was substantially damaged near Catarina, Texas. The certificated flight instructor (CFI) operated the helicopter under the provisions of 14 Code of Federal Regulations Part 91. The flight instructor and his 3 passengers were not injured. The personal flight departed Wimberley, Texas, about midday en route to Catarina, Texas. Visual meteorological conditions prevailed and no flight plan had been filed for the flight. According to the operator, the purpose of the flight was to count deer in the vicinity of the hunting grounds. During the deer counting flight, while hovering out-of-ground effect into the wind, the pilot experienced a "thump" in the flight controls followed by an uncontrollable right turn as a result of the helicopter contacting a tree. The pilot reported that the low-rotor RPM audio sounded and the pilot lost control of the helicopter resulting in a hard landing. The helicopter came to rest on its left side after which the pilot and three passengers exited the aircraft unassisted and uninjured. A review of Federal Aviation Administration (FAA) airman records revealed the pilot held a commercial pilot certificate with ratings for helicopter and instrument helicopter along with a private pilot certificate with ratings for airplane single-engine land and instrument airplane. The pilot also held a flight instructor certificate with a helicopter rating.

The operator revealed that the airframe had a total time of 196-hours at the time of the accident. Additionally, the last annual inspection date is unknown due to the pilot's failure to complete the appropriate forms.
