8.9.6.4 Possible faults in the oil system
After starting the engine, check the engine oil pressure. If it is not OK after 30
seconds there, the engine must be stopped and the cause investigated.
In cold weather, the oil pressure may initially be high until the oil has warmed up
and become more fluid.
Too high an oil pressure can also be caused by a clogged oil system.
Too low an oil pressure can be a sign of a serious engine fault.
Here is an overview of oil pressure, the cause and the required action.
If incorrect oil pressure occurs during flight, you must prepare for
an (emergency) landing, depending on the circumstances.
