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.

Loss of engine power(partial) - nonmechanicalLanding
Engine assembly - failure,partialFactor
Engine assembly - undeterminedFactor
Forced landingLanding - flare/touchdown
Cyclic - improper use ofPilot in commandCause
In-flight planning/decision - inadequatePilot in commandCause
Judgment - inadequatePilot in commandCause
Autorotation - misjudgedPilot in commandCause

Analysis

The pilot in command stated that he was on final approach and at 125 feet AGL, he heard the low RPM audio warning and he immediately entered an autorotation by lowering the collective to the full down position and closing the throttle to the flight idle position. He completed an autorotational landing and he stated his touchdown speed was too fast, so he applied aft cyclic to stop the aircraft.
