Q

Complete loss of tail rotor thrust in flight

A

Reduce throttle to idle, immediately enter autorotation, and maintain a minimum AIRSPEED of 52 KIAS (60 MPH) during descentNOTE
When a suitable landing site is not available, vertical fin may permit controlled flight at low power levels and sufficient AIRSPEED. During final stages of approach, a mild flare should be executed, making sure all power to rotor is off. Maintain helicopter in a slight flare and smoothly use collective to execute a soft, slightly nose-high landing. Landing on aft portion of skids will tend to correct side drift. This technique will, in most cases, result in a run-on type landing.

Q

Fixed pitch failures Note

A

NOTE
If pedals cannot be moved with a moderate amount of force, do not attempt to apply a maximum effort, since a more serious malfunction could result. If helicopter is in a trimmed condition when malfunction occurs, TORQUE and AIRSPEED should be noted and helicopter flown to a suitable landing area. Certain combinations of TORQUE, NR, and AIRSPEED will correct a yaw attitude, and these combinations should be used to land helicopter.

19
Q

TR Fixed Pitch Failure Hovering

A

NOTE
If pedals cannot be moved with a moderate amount of force, do not attempt to apply a maximum effort, since a more serious malfunction could result. If helicopter is in a trimmed condition when malfunction occurs, TORQUE and AIRSPEED should be noted and helicopter flown to a suitable landing area. Certain combinations of TORQUE, NR, and AIRSPEED will correct a yaw attitude, and these combinations should be used to land helicopter.

20
Q

In Flight Left pedal applied TR fixed pitch

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 a comfortable sideslip angle. A decrease in N2 decreases tail rotor thrust. As collective is increased just before touchdown, left yaw will be reduced.

21
Q

In flight Right pedal applied fixed pitch TR

A

n 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.

22
Q

Loss of hydraulic Pressure

A

PROCEDURE:

  1. AIRSPEED — Reduce to 60 to 80 KIAS (69 to 92 MPH).
  2. HYDR SYSTEM circuit breaker — Out. If hydraulic power is not restored, push breaker in.
  3. HYDRAULIC SYSTEM switch — ON; OFF if hydraulic power is not restored.
  4. Land as soon as practical.
  5. A run-on landing at approximately 9 KIAS (10 MPH) is recommended.
23
Q

FLIGHT CONTROL ACTUATOR MALFUNCTION

Explanation

A

Note:Uncommanded movement of an actuator can occur in any flight control axis through one or two flight controls. If two controls move, the pilot will find one of these controls will require a higher than normal control force to oppose the movement. This force cannot be removed without turning the HYDRAULIC SYSTEM switch OFF. Once the hydraulic boost is OFF, the forces on the affected flight control should be similar to the “normal” hydraulic off forces.

24
Q

Flight control actuator malfunction indications and procedures

A

Uncommanded flight control movements.
2. High flight control forces to oppose movement in one axis.
3. Feedback forces only in affected flight control axis.
4. Flight control forces normal in unaffected axis
Procedure: Attitude — Maintain.
2. HYDRAULIC SYSTEM switch — OFF.
3. AIRSPEED — Set to 60 to 80 KIAS (69 to 92 MPH).
4. Land as soon as possible using LOSS OF HYDRAULIC PRESSURE procedure.

25
Q

Generator Failure

A

Indications: GEN FAIL light illuminated.DC loadmeter indicates 0% LOAD.
Procedure:
1. GEN FIELD and GEN RESET circuit breakers — Check in.
2. GEN switch — RESET; then GEN.
3. If power is not restored, place GEN switch to OFF.
4. Land as soon as practical.

26
Q

Note on Generator Failure

A

NOTE
With all electrical equipment OFF, battery, when 80% charged, will operate left fuel boost pump approximately 3 hours to transfer fuel from forward fuel cells and maintain helicopter within CG limits.

27
Q

A

Gen Switches off
Bat switch Off
Left fuel Boost Circuit breaker check in.

28
Q

Warning about battery depletion.

A

206L4: PRIOR TO BATTERY DEPLETION, ALTITUDE SHALL BE REDUCED BELOW 6000 FEET HP. UNUSABLE FUEL MAY BE AS HIGH AS 86.3 POUNDS AFTER BATTERY IS DEPLETED DUE TO INABILITY TO TRANSFER FUEL FROM FORWARD CELLS.206L3+ IGW UPGRADE: PRIOR TO BATTERY DEPLETION, ALTITUDE SHALL BE REDUCED BELOW 6000 FEET Hp. HELICOPTERS NOT EQUIPPED WITH FUEL QTY SWITCH, UNUSABLE FUEL MAY BE AS HIGH AS 156.9 POUNDS (86.3 POUNDS IF EQUIPPED WITH FUEL QTY SWITCH) AFTER BATTERY IS DEPLETED DUE TO INABILITY TO TRANSFER FUEL FROM FORWARD CELLS.206L1+ IGW UPGRADE: PRIOR TO BATTERY DEPLETION, ALTITUDE SHALL BE REDUCED BELOW 6000 FEET HP. UNUSABLE FUEL MAY BE AS HIGH AS 154.4 POUNDS AFTER THE BATTERY IS DEPLETED DUE TO INABILITY TO TRANSFER FUEL FROM FORWARD CELLS.

29
Q

Fuel Transfer Failure

A

FUEL TRANSFER FAILURE
A fuel transfer failure will result in trapped fuel in forward cells and reduce usable fuel by amount remaining in forward cells.
• INDICATIONS:
At total FUEL QTY of approximately 195.8 pounds and below, FUEL QTY in forward cells remains constant.
• PROCEDURE:
1. Determine FUEL QTY in forward cells.
2. Subtract quantity of fuel trapped in forward cells from total to determine usable fuel remaining.
3. Plan landing accordingly.
