Question 13

Complete loss of tail rotor thrust
Indications:
1. Pedal input has no effect on helicopter trim.
2. Right yaw (left sideslip).
3. Left roll of fuselage along the longitudinal axis.
4. Loud bang.

Answer 13

In a hover:
1. Twist grip — Flight idle.
2. Cyclic — Eliminate drift.
3. Collective —Increase to cushion landing.
Transition to forward flight or hover/airtaxi:
1. Twist grip — Flight idle.
2. Cyclic — Eliminate sideward drift.
3. Collective —Increase to cushion landing.
At altitude:
4. Autorotate.
If yaw is not controllable:
5. Twist grip —Flight idle immediately.
If yaw is controllable:
6. Continue powered flight and setup to a suitable landing area at or above minimum rate of descent autorotational airspeed.
7. Autorotate
8. Twist Grip - Rotate to flight idle prior to touchdown
W - Autorotation may be the safest option. Attempting to control a loss of tail rotor thrust in powered flight requires considerable skill and may result in loss of aircraft control.

Airspeed indications during side-slip are unreliable. At airspeeds below approximately 50 knots, the side-slip may suddenly become uncontrollable, and the helicopter will begin an unrecoverable vertical axis “flatspin”.

If attempting to achieve higher airspeeds, care must be taken to avoid excessive cyclic inputs coupled with large power settings that could lead to mast bumping or rapid nose tucking.
