EMERGENCY PROCEDURES
ENGINE - DRIVEN FUEL PUMP FAILURE
In the event of an engine-driven fuel pump failure, gravity flow will
provide sufficient fuel flow for level or descending flight. However, in a
climbing attitude or anytime the fuel pressure drops to 3.0 PSI, the
auxiliary fuel pump should be turned on.
LOW OIL PRESSURE
If low oil pressure is accompanied by normal oil temperature, there is
a possibility the oil pressure gage or relief valve is malfunctioning. A leak
in the line to the gage is not necessarily cause for an immediate precau-
tionary landing because an orifice in this line will prevent a sudden loss of
oil from the engine sump. However, a landing at the nearest airport would
be advisable to inspect the source of trouble.
If a total loss of oil pressure is accompanied by a rise in oil tempera-
ture, there is good reason to suspect an engine failure is imminent. Reduce
engine power immediately and select a suitable forced landing field. Use
only the minimum power required to reach the desired touchdown spot.

ELECTRICAL POWER SUPPLY SYSTEM
MALFUNCTIONS
Malfunctions in the electrical power supply system can be detected by
periodic monitoring of the ammeter and low-voltage warning light;
however, the cause of these malfunctions is usually difficult to determine.
A broken alternator drive belt or wiring is most likely the cause of
alternator failures, although other factors could cause the problem. A
defective alternator control unit can also cause malfunctions. Problems of
this nature constitute an electrical emergency and should be dealt with
immediately. Electrical power malfunctions usually fall into two catego-
ries: excessive rate of charge and insufficient rate of charge. The para-
graphs below describe the recommended remedy for each situation.
EXCESSIVE RATE OF CHARGE
After engine starting and heavy electrical usage at low engine speeds
(such as extended taxiing) the battery condition will be low enough to
accept above normal charging during the initial part of a flight. However,
after thirty minutes of cruising flight, the ammeter should be indicating
less than two needle widths of charging current. If the charging rate were
to remain above this value on a long flight, the battery would overheat and
evaporate the electrolyte at an excessive rate.
