Probable cause
The pilot's excessive airspeed and rate of descent on final approach to land, and subsequent loss of rotor RPM while attempting to flare. The ditch was a related factor.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
A Hughes 369D helicopter landed hard and rolled over. One of the passengers reported the landing approach was fast. A noise was heard as the pilot applied power to arrest the descent for landing. This was followed by activation of the low RPM warning system. Subsequently, the right skid contacted a ditch and the helicopter rolled over.
