A failure leading to fixed T/R pitch 3. T/R cable failure Establish 90 KIAS level flight. Verify T/R pedal authority by gently applying left and right pedal inputs in sequence. COMPLETE LOSS OF T/R THRUST The left and right pedals can be moved freely without any yaw response from the aircraft. IN HOVER • THROTTLE ...................
