The Robinson R-44 helicopter experienced a loss of engine power on the initial climb after takeoff, during an instructional flight. The certified flight instructor (CFI) conducted an autorotation to a nearby construction site; however, the helicopter's skids dug into the muddy ground, and the main rotor blades contacted the tail boom. Examination of the helicopter did not reveal any preimpact mechanical malfunctions. The CFI reported 1,920 hours of total flight experience, which included about 300 hours in the accident helicopter make and model.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
  • A loss of engine power for undetermined reasons.
