Engine overspeed |
Engine overspeed will be indicated by right yaw, rapid increase in both rotor and Engine RPM , and an increase in engine and rotor noise if an engine overspeed is experienced:
Collective - increase to load the rotor and sustain engine / rotor RPM below the maximum operating limit Throttle - adjust until normal operating RPM is attained Land as soon as possible. Perform a power - on approach and Landing by controlling the RPM manually with the throttle.
if RPM cannot be controlled by throttle adjustment... Autorotate went over a safe landing area Enter shut down - accomplish during descent if time permits |

To ensure engine cutoff 8-21 |
To ensure engine cutoff, hold to all in closed position until gas producer (n1) , decelerates to 0 and TURB OUT TEMP is stabilizing. Do not bat switch off , for turn ignition key off comma until gas producer (N1) is 0 and TURB OUT TEMP is stabilized. |

Tq differential |
<5% TQ differential - Ensure adequate room exists for takeoff with minimum or existing PWR. The destination must allow normal or shallow approach to landing areas and a surface which will permit a descent to the ground if necessary. 5-9% TQ differential. Normal approaches and take offs may be performed 10 to 14% TQ differential. Steep approaches, instrument takeoffs and confined area operations may be limited. 15% or more TQ differential. Takeoff and landing restrictions do not apply. |
