NTSB narrative

Shortly after takeoff during cruise flight at 60 knots while over trees no less than 600 feet agl, the engine experienced a total loss of power. The pilot initiated a descent for an autorotative landing and during the descent he reportedly pulled the caution circuit breaker. One of the passengers who is a helicopter rated pilot reported that he did not observe the pilot pull the caution circuit breaker. At 50 feet, he flared but the pilot rated passenger stated that he did not feel the initial collective pull. The pilot stated that he misjudged his landing area distance and while attempting to clear trees below, he intentionally bled the main rotor rpm. The helicopter landed hard in a clearing. Post crash examination of the cockpit revealed that the caution circuit breaker was pulled. Fuel quantity was sufficient to sustain engine operation and no contaminants were found. No discrepancies were noted with the fuel control or power turbine governor. The engine was removed from the helicopter and placed in a test cell where it was operated and found to produce less than full rated power. Disassembly of the engine revealed minor discrepancies. The fuel control and the power turbine governor were bench tested which revealed no mechanical failure or malfunction. No determination could be made as to the reason for the total loss of engine power.

Probable cause

The pilot misjudging the distance of the intended touchdown point resulting in his intentional decrease in the main rotor rpm to clear obstacles below. Contributing to the accident was the total loss of engine power due to undetermined reasons.

  • Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
  • Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
  • The date is the local date, which is the same as the UTC date the NTSB stores.
