Conditions:
At a high hover
Indications: Helicopter begins an uncommanded turn to the right and does not respond
to pilot input to the pedals.
Procedures:
F
Reduce power with collective and attempt to fly away.
NOTE
: If altitude permits, a positive reduction of collective pitch may result in a stopping
or slowing of the “uncommanded turn to the right”, and allow the pilot to fly out
of the condition.
F
Proceed with procedures for complete loss of thrust in forward flight
Conditions: At a low hover
Indications:
Helicopter begins an uncommanded turn to the right and does not respond
to pilot input to the pedals
.
Procedures:
F
Reduce power and altitude with collective, if necessary.
F
As the ground is approached, rotate both twist grips simultaneously to IDLE
and perform a hovering autorotation. Avoid rotating twistgrips with collective
applications during autorotation.
ANTI−TORQUE FAILURE − FIXED THRUSTER SETTING
Conditions: Right pedal applied
Procedures:
F
Adjust airspeed and power for level flight between 80 and 100 KIAS.
F
Use a shallow approach into wind or with a left crosswind to a predetermined
spot.
F
Plan to arrive at the point of intended landing as the airspeed decreases to
translational lift or less, and at a skid height of approximately four to six
feet.
F
While the aircraft is a decelerating attitude, apply collective to stop forward
flight, and as aircraft rotates to the right, place both twistgrips in Fidle" and
perform a hovering autorotation.
NOTE
: Favorable wind conditions may allow a run–on landing without the need to
perform a hovering autorotation.
