2.4.2 ENGINE LIMITATIONS
a) Maximum Rotational Speed
Take-Off and Maximum Continuous: 2600 rpm
b) Oil-temperature
- Maximum 118°C (245°F)
c) Oil capacity
- Maximum sump capacity: 15.13 L (16 US.qt)
- Minimum sump capacity: 8.51 L ( 9 US.qt)
d) Oil pressure
- Minimum Idling 172 kPa (25 psig)
- Normal 379 - 655 kPa (55 - 95 psig)
- Starting,Warm up, Taxi and Take-Off 793 kPa (115 psig)
CAUTION
It is normal for the oil pressure to "flicker" from 69 to 207 kPa (10 to 30 psig) when
going from upright to inverted flight. During knife edge flights and zero-g flights oil
pressure may drop and the oil system may not scavenge resulting in engine failure
or damage if flight is prolonged. Knife edge and zero-g flight should not exceed 10
seconds.
WARNING
If oil pressure drops to 0 kPa (psig) the propeller pitch changes automatically to
coarse (high) pitch with a corresponding decrease in RPM. Apply positive g to avoid
engine stoppage.
e) Fuel pressure
at fuel flow divider:
- Maximum 97 kPa (14 psig)
f) Cylinder head temperature
- Max 241°C (465°F)
