NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The pilot landed the single-engine helicopter in a muddy field after experiencing a loss of engine power while climbing through 200 feet. The pilot reported hearing and feeling a bang, then a jolt to the left, followed by a loss of engine power. The pilot landed the helicopter in a field with furrows, which forced the tail up resulting in a tail strike. After the accident, the pilot reported to the operator that he may have experienced carburetor icing. An overhaul of the engine did not reveal any anomalies that would have prevented the engine's operation. According to the FAA's Carburetor Icing Probability Chart with the reported temperature and dew point, the conditions existed for "Serious Icing at Cruise Power."

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's failure to use carburetor heat, which resulted in a loss of engine power. Factors included the ambient carburetor icing conditions and the lack of suitable terrain for the forced landing.
