Radio failure
Check circuit breakers
Check it’s on
Check it’s plugged in
Transponder to 7600
Continue radio calls
Lookout
Look for ATC light signals
Land and report
Gauges failure
Check circuit breakers
PAN call
Continue with normal circuit
Land and report
Governor Failure RPMs increasing, decreasing or fluctuating
Check circuit breaker and GOV light
Grip throttle firmly to override governor
PAN call
Continue with normal circuit
Keep E and RPM needles in green by careful throttle movements
Land and report
Both RPM needles fail
Check circuit breaker
PAN call
Ensure GOV is on
Normal circuit
Land
Low RRPM warning system remains operative
Shut down
DONT HOVER TAXY
Alternator warning light on
Non essential electric equipment OFF (NAV switch)
Recycle ALT off/on for 1 sec
If still on:
Check circuit breaker
PAN call
Land as soon as practical
Normal circuit
Land and report
Low fuel light
Land immediately
PAN call
Shorten circuit
Normal shut down
NO HOVER TAXY
Clutch light
10 seconds
Pull circuit breaker
Land as soon as practical
PAN call
Shorten circuit
Normal shutdown
DONT HOVER TAXY
Rotor or Engine RPMs fail
Check circuit breaker
GOV ON
Land as soon as practical
PAN call
Normal circuit
Use remaining needle
Land and report
MR temp, chip or TR chip light
Turn towards landing area
PAN call if no other indications land as soon as practical
Perform normal power on landing
SHUTDOWN IMMEDIATELY
If with vibration or banging noise land IMMEDIATELY
Check airspeed and trim and adjust
Turn to landing area
High possibility of power failure
PAN call
Perform a normal proper on landing
Shutdown immediately
Oil light
Cross check with oil pressure gauge and engine tacho.
Land immediately
PAN call
Shorten circuit
Shut down
NO HOVER TAXY
Loss of tail rotor thrust in forward flight
Indicated by right yaw and can’t be corrected with left pedal
Immediately enter AUTO
70kts
Throttle OFF + AUTO landing
Loss of tail rotor thrust in hover
Indicated by right yaw and can’t be corrected with left pedal
Immediately toll throttle OFF
Raise collective to cushion landing
Power failure below 8 feet
Apply right pedal
Raise collective to cushion landing
Power failure while hover taxi
Right pedal
lift collective to cushion landing
BEWARE OF DYNAMIC ROLLOVER
Power failure above 500 feet
Enter AUTO immediately
65 kts approx
Check collective
MAYDAY call
7700 transponder
Touch drills FUEL, KEY, BATTERY
Landing spot + into wind
40 feet roughly - flare
8 feet apply forward cyclic and raise collective before touch to cushion landing and point nose ahead
What causes power loss?
Engine or dive system failure
You’ll notice a sink or yaw if engine fails or if tail rotor fails a spin to right
How to recognise engine failure?
Change in noise level, nose yaw to left, oil and alt lights on and engine RPM decrease
How to recognise a drive system failure?
Noise or vibration, nose yaw to either right or left
Rotor RPM decrease while engine RPM increasing
Over pitching
At max weight or high altitude. Over-pitching can occur downwind downwind when throttle is fully open
