Single Engine Failure - Flight

1.) OEI Flight Condition - Establish

2.) Rotor Speed - Trim to maximum

3.) Affected Engine - Identify

4.) Single Engine Emergency Shutdown - Perform

5.) Land As Soon As Practicable

Concerning TASK 1102 Perform Manual Throttle Operation - Emergency Mode:

a.) The first STANDARD is to perform ____________.

b.) Maximum FLI deviation is _________.

c.) WARNING: It is critical to ensure that when the number ____ throttle is placed into the emergency (EMER) area, that the ___________ does not fall into position ____________.

d.)After landing the ____ will rotate the _________ (affected engine) to _____ prior to reducing the collective lever to the full down position.

Task 1080

+1/-2

P*

Twist grip

idle

Engine Overspeed - Governor Failure

1.) Collective lever - Raise as necessary to maintain N₂ and N_RO within limits

2.) VAR NR system NORM/MAN sw - Check MAN

3.) N2 Trim sw - Try to trim N_RO to 101% with matched torque

If step 3 is not possible:

4.) Affected Engine - Identify

5.) Twist grip (affected engine) - Rotate towards IDLE until N₂ and N_RO stabilize in normal range and FLI needles match

6.) Land As Soon As Practicable

Engine Underspeed - Governor Failure

1.) OEI flight condition - Establish

2.) Bleed air consumers - Off

3.) VAR NR system NORM/MAN pb - Check MAN

4.) Affected engine - Identify

5.) N₂ Trim sw - Compensate N₂/N_RO drop and try to match torque

If torque match is not possible:

6.) Twist grip (affected engine) - Release stop plate and rotate towards FLIGHT until N₂ and N_RO stabilize in normal range and FLI needles match

7.) Land As Soon As Practicable

If no residual torque (affected engine) is available

8.) Single Engine Emergency Shutdown - Perform

During a practice autorotation, before reaching ____ feet AGL, ensure that a steady-state autorotation is attained. If it is not, _____ the maneuver or execute a ________. A steady-state autorotation means that:

a.)

b.)

c.)

d.)

300

abort

go-around

Rotor-RPM is within limits

Aircraft is at the correct airspeed

Aircraft is in trim

Aircraft is in a position to terminate at the intended landing area

Rotor RPM Limitations

Warning Light Indications - ROTOR RPM

Conditions/Indications

N_RO low

-N_RO ____ or less -

- Audio signal -

N_RO high

-N_RO ____ or above -

- Audio signal at _____ or above -

Procedure

N_RO low/N_RO high

1.) Rotor RPM indicator - Check

2.) Collective lever - ____________

95% - steady light

low-pitch beeping tone

106% - flashing light and warning gong

110% - flashing light and steady high-pitch tone

Adjust as necessary to maintain N_RO within normal range

Autorotation

1.) Collective lever - Reduce to maintain N_RO within limits

2.) Airspeed - 75 KIAS Recommended

NOTE Maximum range airspeed 90 KIAS

Minimum rate-of-descent airspeed 60 KIAS

3.) Double Engine Emergency Shutdown - Perform

AT APPROXIMATELY 100 FT AGL:

4.) Flare attitude - Establish (approx. 15 to 20^o) to reduce forward speed and rate of descent; control N_RO

AT APPROXIMATELY 8 TO 12 FT AGL: [Note: 10 - 15’ in ATM]

5.) Flare attitude - Reduce to approx 7^o

6.) Heading - Maintain

7.) Collective lever - Raise to stop descent and cushion landing

8.) BAT MSTR sw - Off

NOTE The appropriate values must be adjusted according to prevailing conditions of gross mass, wind and terrain.
