In either case, if the fire continues longer than a few seconds, the fire should
be extinguished by the best available external means.
If external fire extinguishing is to be applied:
1. Fuel Selector – Off
2. Mixture – Idle cut-off
Engine fires during start are usually the result of over priming. The procedure
above is designed to draw the excess fuel back into the induction system.
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 investigate the cause and
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 dead stick landing can be accomplished. Don't 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 to
POWER OFF LANDING.
LOSS OF FUEL PRESSURE
1. Electric Boost Pump – On
2. Fuel Selector – Check on Full Tank
If problem is not an empty fuel tank, land as soon as practical, and have engine-
driven fuel pump checked.
