Location: La Verne, CA
Accident Number: GAA17CA218
Date & Time: 04/06/2017, 1035 PDT
Registration: N206SA
Aircraft: BELL 206
Aircraft Damage: Substantial
Defining Event: Hard landing
Injuries: 2 None
Flight Conducted Under: Part 91: General Aviation - Instructional

Analysis

The flight instructor in the helicopter reported that he was providing hovering autorotation training to a private pilot. The flight instructor reported that he rolled off the throttle to initiate the maneuver, and the private pilot "raised the collective too soon which resulted in the aircraft climbing." The rotor inertia decayed, and a main rotor blade struck the tailboom after the helicopter struck the ground. The helicopter sustained substantial damage to the tail rotor drive shaft.

The pilot reported that there were no preaccident mechanical malfunctions or failures with the helicopter that would have precluded normal operation.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
 The pilot's early increased application of the collective during a simulated hovering autorotation, which resulted in a loss of rotor rpm and subsequent main rotor blade strike of the tailboom.

Findings

Aircraft
Main rotor control - Incorrect use/operation (Cause)

Personnel issues
Use of equip/system - Pilot (Cause)
Incorrect action sequence - Pilot (Cause)
