3.11 LOSS OF OIL PRESSURE

Loss of oil pressure may be either partial or complete. A partial loss of oil
pressure usually indicates a malfunction in the oil pressure regulating system,
and a landing should be made as soon as possible to allow investigation of the
cause and to prevent engine damage.
A complete loss of oil pressure indication may signify oil exhaustion or
may be the result of a faulty gauge. In either case, proceed toward the nearest
airport, and be prepared for a forced landing. If the problem is not a pressure
gauge malfunction, the engine may stop suddenly. Maintain altitude until such
time as a power off landing can be accomplished. Do not change power settings
unnecessarily, as this may hasten complete power loss.
Depending on the circumstances, it may be advisable to make an off airport
landing while power is still available, particularly if other indications of actual
oil pressure loss, such as sudden increases in temperatures, or oil smoke, are
apparent, and an airport is not close. If engine stoppage occurs, proceed with
Power Off Landing.

3.13 LOSS OF FUEL PRESSURE

If loss of fuel pressure occurs, turn ON the electric fuel pump and check that
the fuel selector is on a tank containing fuel. ·
If the problem is not an empty tank, land as soon as practical and have the
engine-driven fuel pump and fuel system checked.
3.15 HIGH OIL TEMPERATURE
An abnormally high oil temperature indication may be caused by a low
oil level, an obstruction in the oil cooling installation, damaged or improper
baffle seals, a defective gauge, or other causes. Land as soon as possible at an
appropriate airport and have the cause investigated.
A steady, rapid rise in oil temperature is a sign of trouble. Land at the
nearest airport and let a mechanic investigate the problem. Watch the oil pressure
gauge for an accompanying loss of pressure.
