## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of control - in flight, hover
  - rotor rpm - not maintained, dual student (cause)
  - directional control - not maintained, dual student (cause)
  - supervision - inadequate, pilot in command(cfi) (cause)
- Roll over, landing - flare/touchdown
  - autorotation - attempted, pilot in command(cfi)

## Analysis

THE STUDENT PILOT WAS MAKING A 180 DEGREE PEDAL TURN TO THE RIGHT WHILE HOVERING. THE INSTRUCTOR PILOT (IP) STATED THAT AFTER 90 DEGREES OF TURN, THE RATE OF TURNING STARTED TO INCREASE AND THE STUDENT APPLIED LEFT PEDAL TO SLOW THE TURN. THE IP NOTED THAT THE RPM HAD DROPPED BELOW THE NORMAL RANGE AND TOOK CONTROL OF THE HELICOPTER. THE IP INCREASED THE RPM AND ADDED LEFT PEDAL, BUT THE HELICOPTER CONTINUED TO TURN TO THE RIGHT. HE THEN INITIATED A HOVERING AUTOROTATION, BUT DURING TOUCHDOWN, THE HELICOPTER ROLLED OVER.
