b. Fixed Left Pedal
If the tail rotor pitch becomes fixed during cruise or high
power settings, the helicopter will yaw to the left when
power is reduced below 23 inches manifold pressure.
Power settings above 23 inches manifold pressure will
produce near normal flight conditions at airspeeds above
60 MPH. Proceed as follows:
(1) Fly to suitable landing area at a power setting of
at least 23 inches manifold pressure and 60 MPH
or above.
(2) Complete a shallow power-on approach at 60
MPH.
CAUTION
DO NOT AUTOROTATE.
(3) Adjust throttle and collective pitch so that the
helicopter touches down straight ahead at an
airspeed of 0-10 MPH.
(4) Reduce throttle and collective pitch cautiously as
skid gear contacts surface.
NOTE
Application of power to settings greater than 23
inches manifold pressure will make the helicopter
more controllable. Therefore, landing attempt may
be aborted and new approach initiated, if required.
3. Loss of Tail Rotor or Components
The amount of weight lost will determine the helicopter
reaction. If a small amount of weight is lost, the situation
would be similar to a loss of thrust situation. If a large
amount of weight is lost and there is a drastic forward
shift in c.g., immediate autorotation is the only
emergency procedure available.
