Section 3 Emergency Procedures

Question 1

Indications of complete power loss

Answer 1

Left yaw, low engine and rotor speed, change in noise level.

Question 2

Engine failure above 500 ft

Answer 2

Lower collective, right pedal, adjust cyclic 60-80 knots.

Question 3

Engine failure in hover below 12ft.

Answer 3

Right pedal, raise collective.

Question 4

Partial power losd

Answer 4

Start pump on, fly at reduced power to nearest safe landing area and land as soon as possible. Prepare for complete power loss.

Question 5

Air restart at low altitude.

Answer 5

Close twistgrip to cut off position. Press start button immediately. If N1 is 18% or above open twistgrip to ground idle. 25-40% are preferred for coolest and fastest start.

Question 6

Air restart when altitude permits.

Answer 6

Perform normal engine start if N1 has decayed below 18%. Recommended airspeed 60 knots. advance twistgrip from ground idle to full open once N1 reaches 60-65%. Increase collective once N2 and NR are 103%.

Question 7

Low rotor speed.

Answer 7

Lower collective. Check warning lights and instruments for problems.

Question 8

Water landing power off.

Answer 8

Lower collective to enter autorotation. If time permits open doors and push handle full down. Make autorotative approach, flaring as required. Level aircraft and apply full collective as contact is made with water. when aircraft begins to roll lower collective to minimize blades skipping. Release harness and clear aircraft.

Question 9

Water landing power on.

Answer 9

Decend to hover above water. Open doors and push handles full down. Passengers exit the aircraft. Fly safe distance away from personell. Close twistgrip to cutoff and perform hovering autorotation. Allow aircraft to settle in level attitude applying full collective. When aircraft begins to roll lower collective to minimize blades skipping. Release harness and clear aircraft.

Question 10

Water landing power on.

Answer 10

Decend to hover above water. Open doors and push handles full down. Passengers exit the aircraft. Fly safe distance away from personell. Close twistgrip to cutoff and perform hovering autorotation. Allow aircraft to settle in level attitude applying full collective. When aircraft begins to roll lower collective to minimize blades skipping. Release harness and clear aircraft.

Question 11

Cabin smoke and fume elimination.

Answer 11

Question 12

Aircraft evacuation.

Answer 12

Thorough briefing is essential for quick evacuation of passengers and crew when fire is involved.

Question 13

Fire extiguisher

Answer 13

Be familiar with operating and the hazards with the particular type of fire extinguisher installed. Use of Fire extinguisher on canine fire while airborne is not recommended. Pilots first responsibility is to land immediately. If extinguisher is used in flight properly ventilate.

Question 14

Engine fire on the ground. During starting

Answer 14

Twistgrip off. Starter engage until TOT is below 150. Fuel shutoff valve pull closed.

Question 15

Engine compartment fire on the ground.

Answer 15

Twistgrip off. Fuel valve pull to close. Battery off. Passengers evacuate. If time permits. Apply rotor brake if installed. Move passengers a safe distance from aircraft. Use fire extinguisher.

Question 16

Engine fire during flight. At low altitude.

Answer 16

Land immediately power on approach land without delay. Twistgrip off. Fuel valve pull closed. Battery off. Passengers evacuate.

Question 17

Engine fire during flight. At high altitude.

Answer 17

Collective down to enter autorotation. Twistgrip off. Fuel valve pull closed. Radio mayday call. Execute autorotational landing. Battery off. Passengers evacuate.

Question 18

Cabin fire/smoke on the ground.

Answer 18

Twistgrip off. Battery off. Passengers evacuate. If time permits. Apply rotor brake if installed. Move passengers a safe distance from aircraft. Use fire extinguisher.

Question 19

Cabin fire/smoke in flight.

Answer 19

Land immediately power on approach land without delay. Air vents open facing aft. Twistgrip off as soon as on ground. Batter off. Passengers evacuate.

Question 20

Cabin fire/smoke in flight if unable to land immediately and fire source can be identified

Answer 20

Malfunctioning system off. Use fire extinguisher. Ventilate cabin. Land as soon as possible.

Question 21

Cabin fire/smoke in flight if fire source is unknown

Answer 21

Cabin heat off. Generator off. All electrical circuits off. Cabin ventilate. Land as soon as possible.

Question 22

Fuel control/governor failure producing an overspeed

Answer 22

Increase collective to load rotor while rolling throttle towards idle until control of N2 is obtained. Manually control N2 102-103% with throttle. If unable to control rpm close throttle to cutoff and make autorotational landing.

Question 23

Fuel control/governor failure producing an underspeed

Answer 23

Lower collective to maintain rotor rpm. Attempt level flight at 60 knots. If power is insufficient for level flight or power on decent make autorotational landing.

Question 24

Governed surge.

Answer 24

Beep N2 to maximum. Control N2 with throttle.

Question 25

Engine chip detector

Answer 25

Land as soon as possible.

Question 26

Low engine oil pressure in flight.

Answer 26

Land as soon as possible. Shut down engine.

Question 27

Low engine oil pressure on the ground.

Answer 27

Shut down.

Question 28

Loss of engine torque indication in flight.

Answer 28

Land as soon as possible. Shut down.

Question 29

Loss of engine torque on the ground.

Answer 29

Shut down.

Question 30

Transmission oil pressure light.

Answer 30

Land as soon as possible.

Question 31

Transmission oil temperature light.

Answer 31

Land as soon as possible.

Question 32

Transmission chip detector.

Answer 32

Land as soon as possible.

Question 33

Tail rotor chip detector.

Answer 33

Land as soon as possible.

Question 34

Tail rotor loss of thrust forward flight. (right yaw)

Answer 34

Lower collective. Adjust airspeed 50-60 knots. Left lateral cyclic and collective pitch to limit left sideslip. If conditions permit place throttle in idle and perform normal autorotation.

Question 35

Complete loss of tail rotor at hover.

Answer 35

Throttle to idle. Hovering auto.

Question 36

Tail rotor fixed pitch in flight

Answer 36

Adjust to maintain 50-60 knots. Shallow approach with run on landing with speed between translation and 30 knots. Control direction with throttle and collective.

Question 37

One way lock failure.

Answer 37

Reduce airspeed to 100 knots or less. limit cyclic movements. Abnormal movements are not required.

Question 38

Trim failure inoperative trim.

Answer 38

Establish flight that produces least cyclic control force. Normally last trimmed airspeed. Apply trim switch in all directions. If restored trim to near neutral. Land as soon as practical avoiding trimming. If trim failure in all directions and helicopter can be safely maintained check/reset trim circuit breaker. Land as soon as practical if unable to establish full trim control.

Question 39

Runaway trim.

Answer 39

Use legs to relieve right hand and conserve strength for landing. Apply trim in all directions in attempt that generally re establishes trim capability. When restored trim to near neutral and land as soon as practical avoiding trimming. If runaway trim is full forward land into wind avoiding hovering downwind of 15 knots

Question 40

Vibration during flight.

Answer 40

Land as soon as possible. No further flight should be attempted until cause of vibration is identified and corrected.

Question 41

Fuel Filter light.

Answer 41

Turn on start pump. Continue flight.

Question 42

Fuel low light

Answer 42

Slow down less than 130. Avoid large steady side slip angles and uncordinated maneuvers. Land as soon as possible.

Question 43

Gen out light

Answer 43

Check gen circuit breaker is in. Turn gen switch off then on to reset. If light remains on pull gen circuit breaker and insure gen switch is on. Reduce electrical load to minimum. Land as soon as practical.

Question 44

Air filter light.

Answer 44

Filter bypass open. Scav air off. Service filter prior to next flight.
