3.5.1.3 Loss of Tail Rotor Thrust in Level Flight or Descent

Procedures:

Close throttle and reduce collective immediately. Attain an airspeed slightly

above normal autorotative glide speed.

If altitude permits with AIRSPEED above 60 KIAS, throttle and collective may

be gently applied to determine if some degree of powered flight can be

resumed. If unacceptable yawing is experienced, re-enter autorotation and

continue descent to a landing.

Landing technique is same as prescribed for climb condition above.

3.5.2 Loss of Tail Rotor Components

Loss of any tail rotor component will result in a forward CG shift. Other than

additional nose down pitching, this situation would be quite similar to

complete loss of tail rotor thrust as discussed above.

3.5.3 Tail Rotor Fixed Pitch Failures

Indications:

Tail rotor pitch change control failures are characterized either by a lack of

directional response when a pedal is pushed or by locked pedals. If pedals

can not be moved with a moderate amount of force, do not attempt to apply a

maximum effort since a more serious malfunction could result.

3.5.4 Fixed Pitch Failure at a Hover

Procedure:

Do not close throttle unless a severe right yaw occurs. If pedals lock in any

position at a hover, landing from a hover can be accomplished with greater

safety under power controlled flight rather than by closing throttle and

entering autorotation.
