- Decreasing RPM
(R44) Power failure ABOVE 500ft AGL (8 steps)
- Lower collective,aft cyclic, right pedal and enter autorotation

- At 8ft AGL apply forward cyclic to level ship and raise collective just before touchdown to cushion landing
(R44) Power failure below 8ft AGL (3 steps)
- Apply right pedal as required to prevent yawing
- Allow rotorcraft to settle

(R44) Ditching (power off) (3 steps)
- Follow same procedures as for power failure over land until contact water
- Apply lateral right cyclic when aircraft contacts water to stop blades from rotating
- Release seat belt and quickly clear aircraft when blades stop rotating
(R44) Ditching (with power on) (9 steps)
- Descend to hover above water
- Unlatch doors
- Passengers exit aircraft
- Fly to safe distance from passengers to avoid injury (fuel, parts)
- Switch off battery and alternator
- Roll off throttle into indent spring
- Keep aircraft level and apply full collective as aircraft contacts water
- Apply lateral cyclic to stop blades rotating
- release seat belt and quickly clear aircraft when blades stop rotating
Electrical Fire in Flight ( R44) -4 steps

(R44) Loss of Tail rotor thrust in forward flight (R44) Symptom and 3 steps
Symptoms: Indicated by nose yaw right which cannot be corrected by applying left pedal
- Immediatly enter autorotation
- Maintain at least 70KIAS
- Select landing site and roll throttle off into indent spring and perform autorotation landing
Tachometer Failure (R44)
- If 1 fails use remaining tach to monitor RPM
- Allow governor to control RPM and land as soon as practical
Hydraulic system Failure (R44) -4 steps
- Adjust airspeed and flight condition as desired for comfortable control
- HYD swtich - Verify ON
- If hydrolics not restored, HYD switch - OFF
- Land as soon as practical
Governor failure (R44) 3 steps
- Grip throttle firmly to override the governor
- switch governor off
- land as soon as practical
