Robinson R44 II Section 3 Emergancy Procedures Flashcards
(39 cards)
Define Land Immediately
Land on the nearest clear area where a safe normal landing may be performed. Be prepared to enter autorotation during approach, if required.
Define Land as soon as practical
Landing site is at pilots discretion based on nature of problem and available landing areas. Flight beyond nearest airport not recommended.
Indications of an Engine Failure
Low RPM Horn
Change in noise Level
Nose Left Yaw
Oil Pressure Light
Decreasing Engine RPM
Indications of a drive line failure
Unusual Noise
Vibrations
Noise right or left yaw
Decreasing Rotor RPM while engine RPM increases
Power failure above 500 Feet
1) Lower Collective Immediately
2) Establish Glide approx 70 KIAS
3) Rotor RPM 97-108%
4) Select landing spot into wind
5) Air Restart at pilots discretion
6) Unnecessary switches off
7) fuel valve off
- If time permits depress SOS on spider tracks, make mayday call, and activate ELT.
Power Failure between 8 and 500 feet AGL
1) Lower Collective Immediately
2) Rotor RPM 97 to 108%
3) maintain airspeed until ground is approached
- If time permits press Spider tracks SOS button, make Mayday call, Activate ELT
Power Failure below 8 feet AGL
1) Control Yaw
2) Allow rotorcraft to Settle
3) Raise collective to cushion Landing

Air Restart Procedure
- restart not recommended if engine failure is suspected or below 2000 Feet AGL
1) Mixture Off
2) Throttle Closed
3) Starter engaged, cyclic right hand
4) Mixture- move slowly rich while cranking.
Emergency Water Landing Power Off
1) same initial procedure as power failure over land.
2) If time permits unlatch doors
3) release seatbelt, clear aircraft when rotors stop.
Emergency Water Landing Power On
1) Descend to hover above water
2) unlatch doors
3) passengers exit aircraft
4) Fly safe distance away
5) battery and alternator Off
6) perform hover Auto
7) apply Lateral Cyclic to stop Rotor
8) release seatbelt belt and quickly clear aircraft
Loss Of Tail Rotor Thrust in Forward Flight
*Don’t confuse with stuck pedal.
1) Immediately Enter Autorotation
2)maintain at least 70KIAS if Practicable.
3) Select Landing Site
4) roll throttle into over travel and finish autorotation landing
- if no suitable landing spot is available flight possible with reduced power and airspeeds 70 KIAS
Loss of tail rotor thrust in hover
1) immediately roll throttle into over travel
2) finish with hover autorotation
Engine Fire During Start
1) Crank engine and attempt to start
2) if starts running engine short time 60-70%
3) fuel mixture off
4) fuel valve off
5) Battery off
6) if time permits stop rotors
7) exit aircraft
Engine Fire in Flight
1) Don’t Panic, Breathe
2) Enter autorotation
3) cabin heat off if time permits
4) cabin vents open if time permits
5) If engine is running perform normal landing. Then mixture and fuel valve off.
6) If engine quits fuel valve off
7) complete autorotation
8) stop rotors if time permits
9) exit Aircraft
Electrical Fire in Flight
1) battery and Alt off
2) open cabin vents
3) land immediately
4) fuel mixture off
5) fuel valve off
6) stop rotors if time permits
7) exit helicopter
- remember gov and low rpm systems inop when both battery and alternator switched off.
Tachometer Failure in flight
1) determine which tach failed and use other tach to monitor rpm
2) if both have malfunctioned let gov control rpm
3) land as soon as Practical
- special circuit exists to supply power to tachs with battery and alternator switches off. Same circuit powers the clock. If clock doesn’t have power during preflight. Once aircraft is at idle switch both battery and alternator off to check circuit. Talk to maintenance.
Hydraulic System Failure
1) verify Hyd Switch is on
2) if hydraulics are not restored switch off.
3) adjust airspeed and flight conditions for comfort
4) land as soon as practical
Governor Failure
1) Firmly grip throttle
2) switch Governor Off
3) complete flight using manual throttle
Oil Light
Indicates loss of engine power or oil pressure.
1) Check engine tach for power loss
2)check oil gauge for pressure loss.
3) If pressure loss is confirmed land immediately
Engine fire light
Indicates possible fire in engine compartment
MR Temp Light
Indicates excessive temp in gear box.
MR Chip Light
Indicates metallic particles in gear box
