POWER FAILURE – GENERAL

A 
Eng or drivetrain
Low rotor
Eng indications
Drive indications
Lower collective
Enter auto
Power off Vne

A power failure may be caused by either an engine or drive system failure and will usually be indicated by the low RPM horn.

An engine failure may be indicated by a change in noise level, nose left yaw, an oil pressure light, or decreasing engine RPM.

A drive system failure may be indicated by an unusual noise or vibration, nose right or left yaw, or decreasing rotor RPM while engine RPM is increasing.

In case of power failure, immediately lower collective to enter autorotation and reduce airspeed to power-off Vne or below.

CAUTION
Aft cyclic is required when collective is lowered at high airspeed.

CAUTION
Do not apply aft cyclic during touchdown or ground slide to prevent possible blade strike to tailcone.

  1. Lower collective immediately to maintain rotor RPM.
  2. Establish a steady glide at approximately 70 KIAS. (For maximum glide distance or minimum rate of descent, see page 3-3.)
  3. Adjust collective to keep RPM between 97 and 108% or apply full down collective if light weight prevents
    attaining above 97%.
  4. Select landing spot and, if altitude permits, maneuver so landing will be into wind.
  5. A restart may be attempted at pilot’s discretion if
    sufficient time is available (See “Air Restart Procedure”, page 3-3).
  6. If unable to restart, turn unnecessary switches and fuel valve off.
  7. At about 40 feet AGL, begin cyclic flare to reduce rate of descent and forward speed.
  8. At about 8 feet AGL, apply forward cyclic to level ship and raise collective just before touchdown to cushion landing. Touch down in level attitude with nose straight ahead.

Autorotation Landing

Failure is usually indicated by nose right yaw which cannot be corrected by applying left pedal.

  1. Immediately enter autorotation.
  2. Maintain at least 70 KIAS if practical.
  3. Select landing site, roll throttle off into overtravel
    spring, and perform autorotation landing.

NOTE
When a suitable landing site is not available, the vertical stabilizers may permit limited controlled flight at low power settings and airspeeds above 70 KIAS; however, prior to reducing airspeed, enter full autorotation.

NOTE
Low RPM warning system and governor are inoperative with battery and alternator switches both off.

17
Q

TACHOMETER FAILURE

A

Trust other tach
Trust Gov
Land as soon as Practical

If rotor or engine tach malfunctions in flight, use remaining tach to monitor RPM.

If it is not clear which tach is malfunctioning or if both tachs malfunction, allow governor to control RPM and land as soon as practical.

NOTE
Each tach, the governor, and the low RPM
warning horn are on separate circuits. A
special circuit allows the battery to supply
power to the tachs with the battery and
alternator switches both OFF.

18
Q

CYCLIC TRIM FAILURE

A

Land as soon as practical
Turn it off
Land as soon as practiacal

If the automatic cyclic trim fails to compensate for the cyclic feed-back force, land as soon as practical. If the trim generates undesirable forces, switch trim off and land as soon as practical.

19
Q

HYDRAULIC SYSTEM FAILURE

A

Hydros on
Hydos off
Get comfy
Land as soon as practical

Hydraulic system failure is indicated by heavy or stiff cyclic and collective controls. Loss of hydraulic fluid
may cause intermittent and/or vibrating feedback in the controls. Control will be normal except for the increase in stick forces.

  1. HYD Switch – verify ON.
  2. If hydraulics not restored, HYD Switch – OFF.
  3. Adjust airspeed and flight condition as desired for comfortable control.
  4. Land as soon as practical.
20
Q

GOVERNOR FAILURE

A

Grip & override
Gov
Manual throttle

If engine RPM governor malfunctions, grip throttle firmly to override the governor, then switch governor off. Complete flight using manual throttle control.

21
Q

Oil light

A

Tach
Oil gage
Land IMMEDIATELY
Damage may occur

Indicates loss of engine power or oil pressure. Check engine tach for power loss. Check oil pressure gage and, if pressure loss is confirmed, land immediately. Operation without oil pressure will cause serious engine damage and engine failure may occur.

22
Q

Eng Fire LIGHT

A

Indicates possible fire in the engine compartment. See procedures on page 3-6.

23
Q

MR Temp

A

Indicates excessive temperature of main rotor gearbox. See note below.

If light is accompanied by any indication of a problem immediately. If there is no other indication of a problem land as soon as practical.

Break-in fuzz will occasionally activate chip lights. If no metal chips or slivers are found on detector plug, clean and reinstall (tail gearbox must be refilled with new oil). Hover for at least 30 minutes. If chip light comes on again, replace gearbox before further flight.

24
Q

MR Chip light

A

Indicates metallic particles in main rotor gearbox. See note below.

If light is accompanied by any indication of a problem immediately. If there is no other indication of a problem land as soon as practical.

Break-in fuzz will occassionally activate chip lights. If no metal chips or slivers are found on detector plug, clean and reinstall (tail gearbox must be refilled with new oil). Hover for at least 30 minutes. If chip light comes on again, replace gearbox before furthur flight.

25
Q

TR Chip light

A

Indicates metallic particles in tail rotor. See note below.

If light is accompanied by any indication of a problem land immediately. If there is no other indication of a problem land as soon as practical.

Break-in fuzz will occassionally activate chip lights. If no metal chips or slivers are found on detector plug, clean and reinstall (tail gearbox must be refilled with new oil). Hover for at least 30 minutes. If chip light comes on again, replace gearbox before furthur flight

26
Q

LOW

FUEL

A

3 gallons
10 minutes cruise

Indicates approximately three gallons of usable fuel remaining. The engine will run out of fuel after ten minutes at cruise power.

CAUTION
Do not use low fuel caution light as a working indication of fuel quantity.

27
Q

Clutch

A 
Never take off before
10 sec or Flicker
pull breaker
Land as soon as Practical 
Land IMMEDIATELY if

Indicates clutch actuator circuit is on, either engaging or disengaging clutch. When switch is in the ENGAGE position, light stays on until belts are properly tensioned. Never take off before light goes out.

NOTE
Clutch light may come on momentarily during run-up or during flight to re-tension belts as they warm-up and stretch slightly. This is normal. If, however, the light flickers or comes on in flight and does not go out within 10 seconds, pull CLUTCH circuit breaker and land as soon as practical. Reduce power and land immediately if there are other indications of drive system failure (be prepared to enter autorotation). Have drive system inspected for a possible malfunction.

28
Q

Alt light

A

Nonessintials
Switch Off
Switch On
Land as soon as practical

Indicates low voltage and possible alternator failure. Turn off nonessential electrical equipment and switch ALT off then back on after one second to reset alternator control unit. If light stays on, land as soon as practical. Continued flight without functioning alternator can result in loss of power to tachometers, producing a hazardous flight condition.

29
Q

Brake light

A

Indicates rotor brake is engaged. Release immediately in flight or before starting engine.

30
Q

Starter-On

A

Mixture
Batt

Indicates starter motor is engaged. If light does not go out when ignition switch is released from start position, immediately pull mixture off and turn battery switch off. Have starter motor serviced.

31
Q

Gov-Off

A

Turn it on

Indicates engine RPM throttle governor is off.

32
Q

Carbon Monoxide light

A 
Heater
Vents
Land or
Forward flight
Symptoms, Land IMMEDIATELY

Indicates elevated levels of carbon monoxide (CO) in cabin. Shut off heater and open nose and door vents. If hovering, land or transition to forward flight. If
symptoms of CO poisoning (headache, drowsiness, dizziness) accompany light, land immediately.

33
Q

Full Throttle

A

Lower Collective

(if installed)

Indicates engine near full throttle. The governor will be ineffective because it cannot increase throttle to maintain RPM. Lower collective as required to extinguish light.

34
Q

LOW RPM HORN and CAUTION LIGHT

A

Roll on throttle
Lower collective
Aft cyclic

A horn and an illuminated caution light indicate that rotor RPM may be below safe limits. To restore RPM, immediately roll throttle on, lower collective and, in forward flight, apply aft cyclic. The horn and caution light are disabled when collective is full down.
