## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(-23) PILOT WAS GIVING FLIGHT INSTRUCTION TO PASSENGER/STUDENT, ^PRIVACY DATA OMITT^ INCLUDING HANDS ON OF CONTROLS IN A HOVER, APPROXIMATELY 3 FEET OFF THE GROUND, WHEN HE LET THE STUDENT HAVE SOLE CONTROL OF THE CYCLIC CONTROL WITH HIMSELF (THE PILOT) HAVING SOLE CONTROL OF THE ANTI-TORQUE AND COLLECTIVE CONTROLS. THEY WERE FACING INTO THE WIND AND KEPT THAT HOVER POSITION FOR 15-20 SECONDS WHEN THE PILOT NOTICED THE COLLECTIVE WAS VERY HARD TO CONTROL. REALIZING THE COLLECTIVE FRICTION HAD INCREASED DURING THEIR HOVERWORK, THE PILOT FAILED TO TAKE POSSESSION OF ALL THE CONTROLS BEFORE THE AIRCRAFT'S MAIN ROTOR BLADE HIT THE GROUND AND SUBSEQUENT SUBSTANTIAL DAMAGE OCCURRED.

## The NTSB's investigation of this event (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.

Probable cause: the student's improper use of the cyclic control, the flight instructor's inadequate supervision, and his delayed remedial action. A factor in the accident was the CFI's diverted attention.
