Read the full NTSB narrative
The certified flight instructor (CFI) and student pilot were on a local instructional flight. The CFI stated that during cruise flight, the rpm dropped suddenly and he lowered the collective while rolling on the throttle. The engine did not respond and the helicopter impacted the ground. The CFI indicated that carburetor heat had been applied shortly before the power loss occurred. Post accident test run of the engine did not reveal any operational anomalies. At the time of the accident, the Federal Aviation Administration icing probability chart showed that icing conditions existed at glide and cruise power.
