5
Q

Large drop in fuel flow rate

A

Same symptoms as engine failure but after a few seconds the NG will stabilize at low rpm (less than 70%)
Enter auto
FFCL into emergency sector (forward)
Ng and t4 should rise, control engine speed to 70% Ng
If necessary increase collective to bring NR to 350
Increase fuel flow until NR is apprrox 380
Trim collective pitch and FFCL to hold level flight at this NR

Q

Excessive fuel flow rate

A

NG, T4, and Torque increase
Do not reduce collective
Reduce fuel flow until the NR corresponds to a position of the indicator pointer in the center of green area
Continue flight, any reduction of collective pitch will cause an increase in rotor speed which must be counteracted by adjusting the fuel flow control position.

Q

Surging

A

Hunting of rpm, torque and T4
Reduce the collective
It may be pessary to reduce fuel flow slightly to leave the governed range, if surging still persists land as soon as possible.

Q

Smoke in cabin source not identified

A

Heating demisting off
If smoke does not clear, Master “all off” switch
All switches off
Reset battery on and reset “all off” master
Check generator (if okay) turn on each system one by one)

Q

No fuel pressure

A

Confirmed by Fuel P light, if no light faulty pressure gauge and flight may be continued

17
Q

Low Fuel pressure

A

Confirmed by F FILT light, if no light fault pressure gauge and flight may be continued.

18
Q

Low engine oil pressure

A

“gauge pointed in red arc for Ng above 85%”
Check CWP for ENG P Light

No light (bulb out)

  • Torque low, shut down engine, auto
  • Torque correct, land as soon as possible

Light (bulb works)

  • Torque low, land as soon as possible
  • Torque correct, Land as soon as practicable, monitor ENG P. light
19
Q

Eng oil temp high (low speed or hover)

A

Land if possible, check cooler fan operates

or

Increase speed and reduce power (80 kts)
If still high land as soon as possible.

20
Q

Ng Indicator Failure

A

Monitor T4 and Torque

T4 above 15 c 750 max

21
Q

Torque Failure

A

Monitor Ng limit below 98% for LA conditions

22
Q

T4 Failure

A

Comply with Ng indications, do not attempt to start engine

23
Q

Nr failure

A

Maintain torque >10%

Land as soon as practicable

24
Q

Yaw Servo-control Slide-valve Seizure In hover

A

If no movement about yaw axis land normal

If aircraft yaw, cut off hydraulic switch on collective

25
Q

Yaw Servo-control Slide-valve Seizure In cruise flight

A

Reduce speed, enter slide slip if necessary, cut off hydraulic pressure

26
Q

Main servo control slide valve seizure

A

Cut off hydraulic on collective
60 kts
Follow HYD failure procedure
