Under very cold conditions, it may be necessary to preheat
the engine prior to a start. Particular attention should be
given to the oil cooler, engine sump and propeller hub to
ensure proper preheat. A start with congealed oil in the
system may produce an indication of normal pressure im-
mediately after the start, but then the oil pressure may de-
crease when residual oil in the engine is pumped back
with the congealed oil in the sump. If an engine heater
capable of heating both the engine sump and cooler is not
available, the oil should be drained while the engine is hot
and stored in a warm area until the next flight.
If there is no oil pressure within the first 30 seconds of
running, or if oil pressure drops after a few minutes of
ground operation, shut down and check for broken oil
lines, oil cooler leaks or the possibility of congealed oil.
NOTE
It is advisable to use external power for start-
ing in cold weather.
During warm-up, monitor engine temperatures closely,
since it is quite possible to exceed. the cylinder head
temperature limit in trying to bring up the oil temperature.
Exercise the propeller several times to remove cold oil from
the pitch change mechanism. The propeller should also be
cycled occasionally in flight.
During letdown and landing, give special attention to en-
gine temperatures, since the engine will have a tendency
toward overcooling.
ICING CONDITIONS
Flight in Icing Conditions Is Prohibited.
