A
- if torque too low
- shut down engine
- if torque normal
- land as soon as Possible
21
Q
Low Engine Oil Pressure
ENG P. does illuminate
A
- if torque too low
- land as soon as Possible
- if torque normal
- land as soon as Practicable
- monitor ENG P. light
22

- increase speed and reduce power
- 80 kt
- if no change land as soon as possible
23
Q
Engine Oil Temperature - Flight
A
- Reduce power
- Land if possible
- check cooler fan
- if landing not possible
- increase speed and reduce power
- 80 kt
- if no change land as soon as possible
24
Q
TR Failure - IGE
A
Reduce collective
25
TR Failure - OGE
- Reduce collective moderately
- Increase speed
26
TR Failure - Forward Flight
- Reduce the power as much as possible
- Select landing area for a steep approach
- On final shut down the engine
27

- Do not exceed max torque
- Below 15c: 730c
- Above 15c: 750c
28

30
Abnormal NR/Nf Readings -
NR/Nf Below Green Arc
- Excessive power demand: reduce collective pitch. Indicator reading should rise to governed valve.
- Governor failure: Governor procedure

Abnormal NR/Nf Readings -
Different NR/ Nf Readings
- NR exceeds Nf
- NR reading is incorrect
- Nf exceeds NR
- NR reading is probably incorrect

- Maintain engine torque above 10%
- NR reading is given by the Nf
- Land asa Practicable
33
