This is a situation involving a loss of effective tail rotor thrust without a break in the drive system which cannot be stopped with full left pedal application. If LTE is experienced, simultaneously:
- 1. Pedal - Full Left
- 2. Cyclic - Forward
- 3. As recovery is effect, adjust controls for normal flight
WARNING: collective reduction will aid in arresting the yaw rate; however, if a rate of descent has been established, collective reduction may increase the rate of descent to an excessive value. The resultant large and rapid increase in collective to prevent ground or obstacle cantact may further increase the yaw rate, decrease the rotor RPM and cause an overtorque and/or over-temperature condition. Therfore, the decision to reduce collective must be based on the pilot's assessment of the altitude available for recovery. If spin cannot be stopped and crash is imminent, an autorotation may be the best course of action. Maintain full left pedal until the spin stops, then adjust to maintain heading.
