Operated by Silver State Helicopters LLC (per NTSB report)

A loss of engine power due to carburetor icing. Contributing to the accident was unsuitable terrain for a forced landing.

Operated by Silver State Helicopters (per NTSB report)

An excessive descent rate during a simulated 180-degree power-off autorotation, and the flight instructor's failure to initiate corrective action in time to keep the helicopter from impacting the terrain.

Operated by Silver State Helicopters (per NTSB report)

The pilot's improper recovery from a bounced landing.

Operated by Silver State Helicopters (per NTSB report)

The student pilot's failure to adequately compensate for the crosswind conditions and to maintain directional control.

Operated by Silver State Helicopters (per NTSB report)

The student pilot's loss of directional control while hovering, and the instructor pilot's inadequate remedial action while attempting to take control of the helicopter.

Operated by Silver State Helicopters (per NTSB report)

The student pilot's failure to maintain rotor RPM during landing approach, and the delayed remedial action by the flight instructor. A contributing factor was the high density altitude weather condition.

Operated by Silver State Helicopters LLC (per NTSB report)

The student pilot's improper use of the throttle and cyclic, and the certified flight instructor's inadequate supervision, which resulted in the collision with terrain.

Operated by Silver State Helicopters (per NTSB report)

Clearance was not maintained after landing by the pilot of the other aircraft, which resulted in an on ground collision with the helicopter standing near the refueling pumps. The aircraft standing in the refueling area was a factor.

Operated by Silver State Helicopters (per NTSB report)

The flight instructor's inadequate remedial action following a loss of control in flight. A factor to the accident is that the dual student did not maintain directional control of the helicopter while manuevering, which subsequently caused the instructor to lose control of the helicopter.

Operated by Silver State Helicopters (per NTSB report)

The failure of the student pilot to maintain an adequate main rotor rpm and the instructor’s failure to maintain control of the aircraft.

Operated by Silver State Helicopters, LLC (per NTSB report)

Disconnection of the throttle control linkage due to improper maintenance, which resulted in a loss of engine power during initial climb.

Operated by Silver State Helicopters LLC. (per NTSB report)

The pilot's failure to maintain control of the helicopter following an encounter with dynamic rollover.

Operated by Silver State Helicopters (per NTSB report)

The pilot inadvertently allowing the helicopter to enter into a vortex ring state (settling with power) condition while he was lowering a long-line load to the ground, resulting in the helicopter settling to the ground and its tail rotor impacting part of the rigging used to haul the load. Factors include the long-line load and its rigging sitting on the ground at the point where the helicopter settled to the terrain.

Operated by Silver State Helicopters (per NTSB report)

The pilot's selection of an unsuitable terrain for landing. A contributing factor was the lack of suitable terrain.

Operated by Silver State Helicopters, LLC (per NTSB report)

The student pilot's failure to maintain control of the helicopter and delayed remedial action by the flight instructor.

Operated by Silver State Helicopters (per NTSB report)

the flight instructor's failure to maintain control of the helicopter during the attempted autorotation after the loss of engine power for reasons undetermined. Contributing factors include the flight instructor's improper preflight planning, the high density altitude, and the attempted autorotation.

Operated by Silver State Helicopters (per NTSB report)

the student's failure to maintain adequate main rotor rpm when performing a180-degree autorotation, and the instructor's inadequate supervision and delayed remedial action. A factor in the accident was the high density altitude.

Operated by Silver State Helicopters (per NTSB report)

the student pilot's failure to maintain control of the helicopter during the landing. Contributing to the accident was the flight instructor's inadequate supervision of the student pilot.

Operated by Silver State Helicopters (per NTSB report)

the student's failure to maintain control of the helicopter. Contributing factors were high airspeed, high rate of descent, the instructor's delay in taking remedial action, and the instructor's inadequate supervision of the flight.

Operated by Silver State Helicopters (per NTSB report)

the pilot's failure to maintain adequate rotor rpm during a practice autorotation, and the flight instructor's improper flare. A contributing factor was the instructor's inadequate supervision of the pilot.

Operated by Silver State Helicopters (per NTSB report)

the pilot's inadequate in-flight planning/decision, which resulted in fuel exhaustion and loss of engine power due to an inadequate fuel supply.

Operated by Silver State Helicopters (per NTSB report)

the student pilot's improper liftoff into tailwind conditions, improper use of the collective, and failure to relinquish the flight controls to the CFI, resulting in the helicopter colliding with terrain. Also causal was the CFI's inadequate supervision and delayed remedial action.

Operated by Silver State Helicopters, LLC (per NTSB report)

The pilot's misjudged landing flare during an autorotation, which resulted in a hard landing. The pilot's failure to follow the listed emergency procedures in the rotorcraft flight manual and the partial failure of the rotor system's drive belts were factors.
