Section III (Emergency Procedures)
Engine Failure - Alt. above 450 ft. |
1. Lower collective pitch.
2.Enter normal autorotation. 3.Establish a steady glide of 52kt IAS Approximately. 4At an altitude of approximately 50 ft, initiate a flare. 5. At approximately 10 feet, coordinate collective pitch with forward movement of cyclic stick to level aircraft and cushion landing. Make ground contact with aircraft level. |
|
Section III (Emergency Procedures)
Engine Failure - Alt. above 7 ft and below 450 ft. |
Conduct takeoff operation in accordance with the restrictions shown on Height Velocity Diagram.
1. In event of power failure during takeoff, lower collective pitch (altitude permitting), in order to maintain the rotor speed. The amount and duration of collective reduction depends upon the height above the ground at which the engine failure occurs. 2.As the ground is approached, use aft cyclic and collective as needed to decrease forward and vertical velocity. 3.Establish a level attitude prior to ground contact. Apply collective pitch as necessary in order to cushion landing. |
|
Section III (Emergency Procedures)
Engine Failure - Below 7 ft. |
A power failure is indicated by sudden yawing of the ship to the left.
1. Apply right pedal to prevent excessive yawing and right stick to minimize drift. 2. Apply collective pitch as necessary in order to cushion landing. |
|
Section III (Emergency Procedures)
Ditching - Power off |
Follow the procedures for autorotation approach and landing. Upon contact with water, proceed as follow:
1.Lower collective pitch and apply sidewards cyclic stick after contact is made with water. 2.Release seat belt and shoulder harness. 3.Open both doors and exit helicopter. |
|
Section III (Emergency Procedures)
Ditching - Power ON |
1.Descend to hovering altitude over water;
2.Unlatch doors; 3.Passenger exit aircraft; 4.Fly a safe distance away; 5.Turn battery and alternator switches OFF; 6.Close twistgrip to idle position; 7.Allow aircraft to settle in a level altitude, apply full collective; 8.When aircraft begins to roll, reduce collective to full down. 9.Release seatbelt and shoulder harness; 10.When rotor blades have stopped turning, clear aircraft as quickly as possible; |

Section III (Emergency Procedures)
M/R XMSN TEMP/PRESS |
A red light comes on when transmission oil pressure drops below 2-1/2 psi or temp. exceeds 235ºF.
Land as soon as possible. |
|
Section III (Emergency Procedures)
M/R XMSN CHIPS |
An amber caution light will come on to indicate possible deterioration of components within the main rotor transmission.
Land as soon as possible. |
|
Section III (Emergency Procedures)
T/R XMSN CHIPS |
An amber caution light will come on to indicate possible deterioration of components within the tail rotor transmission.
Land as soon as possible. |
|
Section III (Emergency Procedures)
Low Fuel, Caution Indicator |
An amber fuel low caution light (FUEL LOW) on the instrument panel comes on in flight when approximately on gallon of usable fuel remains in the tank.
Land immediately. |
|
Section III (Emergency Procedures)
Clutch Warning Light |
A red clutch warning light (RELEASE) is illuminated whenever the clutch is not fully engaged.
Be prepared to enter autorotation. Land as soon as possible. |
|
Section III (Emergency Procedures)
Tail Rotor Failure In Forward Flight |
Failure is normally indicated by uncontrolled yaw to the right.
1.Reduce power by lowering the collective. 2.Adjust airspeed to 50 to 60 knots. 3.Use left lateral cyclic in combination with collective pitch to limit left slideship to a reasonable angle. 4.If conditions permit, place the twistgrip in the idle position once a landing area is selected, and perform a normal autorotation. Plan touch down with little or no foward speed. |
|
Section III (Emergency Procedures)
Tail Rotor Failure While at a Hover |
Failure is normally indicated by uncontrolled yaw to the right.
While at a hover: Place the twistgrip in the IDLE position and perform a normal hovering autorotation. |
|
Section III (Emergency Procedures)
Tail Rotor Control Failure - Fixed Pitch Setting |
1.Adjust power to maintain 50 to 60 knots airspeed.
2.Perform a shallow approach and running landing to a suitable area, touching down into wind at a speed between ETL and 30 knots. Directional control may be accomplished by small adjustments in throttle and/or collective control. |
