Dual student's failure to properly flare the helicopter during the autorotation power recovery and the cfi's failure to adequately supervise the dual student's performace during a critical phase of flight.
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
While practicing power recovery autorotations the dual student plt flared in a nose low attitude. The CFI attempted to flare the helicopter but it struck the ground before the descent could be arrested. The CFI reported that the helicopter did not experience any preimpact mechanical malfunctions.
