Power failure - hover below 8 feet AGL

The helicopter will normally exhibit little or no tendency to depart in pitch
or roll, hence requiring little correction :
1. Use left pedal input to counter yawing to the right,
2. Cushion landing by raising collective, until high pitch stop if
necessary,
3. Once landed, lower the collective.

Power failure during take-off

Take-off acceleration is the most critical situation for a power failure to
occur, requiring moderate and rapid pilot reaction :
1. Use left pedal input to counter yawing to the right,
2. Use aft cyclic to level the helicopter,
3. Before having reached 30 kt IAS, do not lower the collective,
4. If IAS is above 30 kt IAS, slightly pitch up while slightly
lowering the collective, if needed, to prevent climbing,
5. When approaching the ground, raise the collective to cushion
contact,
6. Use pedals to minimize ground drift,
7. Once stopped, lower the collective.

Other in-flight power failures

All cases :
1. Lower the collective immediately and maintain full down,
2. Use pedals to control yaw,
3. Maintain IAS between 30 and 50 kt IAS (50 kt IAS
recommended),
4. Select landing area and manoeuvre to land into the wind,
5. Adjust collective to centre NR in green arc,
6. When the landing is ensured, consider engine restarting if
enough time is available. Refer to page 3-5.
7. At about 60 feet AGL, apply aft cyclic to raise the helicopter
nose smoothly and continuously. Below 50 kt IAS, this
manoeuvre will not stop sink rate.
8. As ground closes-on, apply forward cyclic to level the helicopter
while raising the collective to stop sink rate.
9. Use pedals to minimize ground drift,
10. Once stopped, lower the collective.
Note : Average manoeuvre requires about 200 to 300 m (650 to 1000
feet) free of high obstacle.
