Q

R44 power failure general

A

engine or drive system failure usually 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 RPMA 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

Q

R44 POWER FAILURE ABOVE 500 FEET AGL

A
  1. Lower collective turn into wind
  2. Establish a steady glide at 70 KIAS
  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
  5. A restart may be attempted at pilot’s discretion if sufficient time is available
  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.

Q

R44 POWER FAILURE BETWEEN 8 FEET AND 500 FEET AGL

A
  1. Lower collective immediately to maintain rotor RPM.
  2. Adjust collective to keep RPM between 97 and 108% or apply full down collective if light weight prevents attaining above 97%.
  3. Maintain airspeed until ground is approached, then begin cyclic flare to reduce rate of descent and forward speed.
  4. 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 and nose straight ahead.

Q

R44 emergency water landing power OFF

A
  1. Follow same procedures as for power failure over land until contacting water. If time permits, unlatch doors prior to water contact.
  2. Apply lateral cyclic when aircraft contacts water to stop rotors.
  3. Release seat belt and quickly clear aircraft when rotors stop.

  4. Fly to safe distance from passengers to avoid possible injury by rotors.
  5. Switch battery and alternator OFF.
  6. Roll throttle off into overtravel spring.
  7. Keep aircraft level and apply full collective as aircraft contacts water.
  8. Apply lateral cyclic to stop rotors.
  9. Release seat belt and quickly clear aircraft when rotors stop.

Q

R44 Loss of tail rotor thrust in forward flight

A

1.failure indicated by nose right yaw which cannot be corrected by left pedal
2.Enter auto
3.maintain at least 70kts
4.select landing site, roll throttle off into detent spring and perform autorotation landing
vertical fin may permit limited controlled flight at low power setting and IAS above 70kts
re-enter auto for landing

Q

R44 Engine fire during start

A
  1. cranking, continue and attempt to start which would suck flames and excess fuel into engine
  2. if engine starts, run at 60-70% for a short time shut down and inspect for damage
  3. if engine fails to start, shut off fuel and master switch
  4. extinguish with fire extinguisher, wool blanket or dirt
  5. inspect for damage

Q

R44 Tach failure

A

use remaining tach to monitor RPM, if it is unclear which tach is malfunctioning or both tachs malfunction allow governor to control RPM and land as soon as practical

Q

R44 Hydraulic system failure

A
  1. Hyd switch verify ON
  2. if hydraulics are not restored, HYD switch OFF

23
Q

R44 clutch

A

indicates clutch actuator is on, if light flickers or comes on in flight and does not go out within 10s pull clutch circuit breaker and land as soon as practical. if other indications of a drive system failure reduce power and land immediately (be prepared to enter auto)

24
Q

indicates low voltage, turn off nonessential electrical equipment and switch alt off and back on to reset. if light stays on land as soon as practical

25
Q

R44 brake

A

rotor brake engaged

26
Q

R44 Starter on

A

indicates starter is on, if light does not go out when starter is released immediately pull mixture off and turn master battery off

27
Q

R44 Gov off

A

indicate rpm gov is off

28
Q

R44 carbon monoxide

A

shut off heater open nose and door vents, if hovering transition to fwd flight
if symptoms of CO poisoning land immediately
