Driveshaft Failure

A
  1. Maintain heading and altitude control.
  2. Collective - Adjust as required to maintain 85 to 107% NR.
  3. Cyclic - Adjust to obtain desired autorotative airspeed.

Q

FADEC failure

A
  1. Throttle - If time permits, match throttle bezel position to NG indication.
  2. NR/NP - Maintain 95 to 100% with collective and throttle.
  3. FADEC MODE switch - Depress one time, muting FADEC fail audio. AUTO RELIGHT advisory light illuminates.

Note: Depressing FADEC MODE switch one time, will only mute FADEC fail audio and activate ignition. This step should not be accomplished until pilot is firmly established in MAN control.

  1. Land as soon as practical.
  2. Normal shutdown if possible.

Q

Electrical Fire

A
  1. Vents/side windows - Open, as required; ventilate cabin.

If source of the smoke or fire cannot be positively identified:

  1. GEN switch - OFF
  2. Land as soon as practical.

17
Q

Complete loss of tail rotor thrust.

A

Hovering - Close throttle and perform a hovering autorotation landing. A slight rotation can be expected on touchdown.

In Flight - Reduce throttle to idle, immediately enter autorotation, and maintain a minimum AIRSPEED of 55 KIAS during descent.

18
Q

Fixed Pitch Failures - Hovering

A

Do not close throttle unless a severe right yaw occurs. If pedals lock in any position at a hover, landing from a hover can be accomplished with greater safety under power-controlled flight rather than by closing throttle and entering autorotation.

19
Q

Fixed Pitch Failure - In Flight, Left Pedal Applied

A

In a high power condition, helicopter will yaw to left when power is reduced. Power and AIRSPEED should be adjusted to a value where a comfortable yaw angle can be maintained. If AIRSPEED is increased, vertical fin will become more effective and an increased left yaw attitude will develop. To accomplish landing, establish a power-on approach with sufficiently low AIRSPEED (zero if necessary) to attain a rate of descent with comfortable sideslip angle. (A decrease in NP decreases tail rotor thrust.) As collective is increased just before touchdown, left yaw will be reduced.

20
Q

Fixed Pitch Failure- In Flight, Right Pedal Applied

A

In cruise flight or reduced power situation, helicopter will yaw to right when power is increased. A low power, run-on type landing will be necessary by gradually reducing throttle to maintain heading while adding collective to cushion landing. If right yaw becomes excessive, close throttle completely.
