SECTION 3
EMERGENCY PROCEDURES
(
The presence of fire is noted through smoke, smell and heat in the cabin. It is essential that the
sourc~
of the fire be promptly identified through instrument readings, character of the smoke, or other indications
since the action to be taken differs somewhat in each case.
Check for the source of the fire first.
If an electrical fire is indicated (smoke in the cabin), the master switch should be turned "OFF." The
cabin vents should be opened and the cabin heat turned "OFF." A landing should be made as soon as
possible.
If
an engine fire is present, switch the fuel selector to "OFF" and close the throttle. The mixture
should be at idle cut-off. Tum the electric fuel pump "OFF." In all cases, the heater and defroster should
be "OFF." If radio communication is not required, select master switch "OFF." Proceed with power off
landing procedure.
NOTE
The possibility of an engine fire in flight is extremely remote. The
procedure given is general and pilot judgment should be the
determining factor for action in such an emergency.
3.17 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.
I
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.
I I' engine stoppage occurs, proceed with Power Off Landing.
