ANTI-TORQUE FAILURE - FIXED THRUSTER SETTING
Conditions:
Right pedal applied:
This condition results in a thruster opening on the right
and may be understood either as a “stuck right pedal” or a break in the rotating
cone controls with the right pedal applied. In either failure mode, the thruster
would be opened on the right producing a thrust vector that causes the aircraft
to yaw to the right. The degree of yaw will be determined by the position of
the rotating cone at the time of failure.
Procedures:
Adjust airspeed and power for level flight at an airspeed between 80 and
100 KIAS.
Do not attempt an autorotation from forward flight unless an actual
dual engine failure occurs.
If able, place pedals in “neutral” position (approximately one inch [25mm]
of right pedal).
NOTE
:
With pedals in neutral, the NOTAR fan will be at minimum pitch.
Select an approach direction that offers a left quartering headwind to reduce
the touchdown ground speed and the amount of right yaw.
Perform a shallow approach to a hard surface or other suitable area at a mini
mum airspeed of 80 knots.
Select collective friction to 5 pounds.
Turn VSCS OFF.
An aggressive reduction in power (similar to a “quick stop”) as the air
craft is decelerated prior to landing should yaw the aircraft to the left.
As the ground is approached, level the aircraft and adjust collective as
necessary to align the aircraft with the touchdown direction and cushion
the landing. Landing speed should be as slow as possible, not to exceed
30 knots.
If necessary, just prior to or at the moment of touchdown, rotate both twist
grips simultaneously toward IDLE to assist in maintaining directional control.
NOTE
:
This action will place both engines in the manual mode.
