Q

EMERGENCY WATER LANDING - POWER OFF

A

Same procedure for power failure over land
Unlatch doors
Apply lateral cyclic when contact with water
Release seat belts
Quickly clear aircraft when rotors stop

Follow same procedures as for power failure over land until contacting water. If time permits, unlatch doors prior to water contact.

Apply lateral cyclic when aircraft contacts water to stop rotors

Release seat belt and quickly clear aircraft when rotors stop

Q

ENGINE FIRE DURING START ON GROUND

A

Cranking- continue and attempt to start which would suck flames and excess fuel into engine

If engine starts, run at 60 to 70% RPM for a short time

Fuel mixture-off

Fuel valve- off

Battery switch-off

If time permits, apply rotor brake to stop rotors

Exit helicopter

Q

ENGINE FIRE IN FLIGHT

A

Enter autorotation
Cabin heat- off
Cabin vent- on
If engine is running, perform normal landing, then fuel mixture off and fuel valve off

If engine stops running, fuel valve off and complete autorotation
Battery switch- off
If time permits, apply rotor brake to stop rotors
Exit helicopter.

Q

TACHOMETER FAILURE

A

Use remaining tech to monitor RPM
If unsure which tach is malfunctioning or if both techs malfuncunition allow governor to control rpm
Land as soon as practical

17
Q

HYDRAULIC SYSTEM FAILURE

A

Indicated by heavy or stiff cyclic and collective controls

Loss of hydraulic fluid may cause intermittent and or vibrating feedback in controls

HYD switch- verify on
If hydraulics not restored HYD switch- off
Adjust airspeed and flight condition as desired for comfortable control
Land as soon as practical

18
Q

GOVERNOR FAILURE

A

Grip throttle firmly to override governor
Switch governor off
Complete flight using manual throttle control

19
Q

OIL LIGHT

A

Indicates loss of engine power or oil pressure

Check engine tach for power loss
Check oil pressure gauge
If pressure loss is confirmed land immediately

Continued operations without oil pressure will cause serious engine damage and engine failure may occur

20
Q

ENG FIRE

A

Indicates possible fire in the engine compartment

21
Q

MR TEMP

A

Indicates excessive temperature of main rotor gearbox

22
Q

MR CHIP

A

Indicates metallic particles in main rotor gearbox

23
Q

TR CHIP

A

Indicates metallic particles in tail rotor gearbox

If light is accompanied by any indication of a problem land immediately.

24
Q

LOW FUEL

A

Indicates approximately 3 gallons off useable fuel remaining.

The engine will run out of fuel after ten minutes at cruise power

25
Q

CLUTCH

A

Indicates clutch actuator circuit is on, either engaging or disengaging.

Clutch light stays on longer than 10 seconds pull clutch circuit breaker.

Land as soon as practical

Reduce power and land immediately if any indications of drive system failure.

26
Q

ALT LIGHT

A

Indicates low voltage and possible alternator failure

Turn off nonessential electrical equipment
Switch ALT off then back on
If light stays on land as soon as practical

27
Q

BRAKE LIGHT

A

Indicates rotor brake is engaged

Release immediately in flight or before starting engine

28
Q

STARTER ON LIGHT

A

Indicates starter motor engaged

If light does not go out when ignition switch is released from start position,

Immediately pull mixture
Turn battery switch off
Have starter motor serviced

29
Q

GOV OFF LIGHT

A

Indicates engine RPM throttle governor is off

30
Q

LOW RPM HORN AND CAUTION LIGHT

A

Indicate Rotor RPM may be below safe limits.
Immediately roll throttle on
Lower collective
Apply aft cyclic

Hor and caution light are disabled when collective is full down.
