EMERG PROCEDURES
Upon restart. if normal engine operation is not established promptly,
select LOW pump setting.
If engine failure was caused by engine driven fuel pump failure the
throttle must be retarded to regain power. The auxiliary fuel pump will not
supply sufficient fuel to run the engine at full power.
If engine failure was caused by fuel exhaustion, power will not be
regained after switching fuel tanks until the empty fuel lines are filled. This
may require up to ten seconds.
If power is not regained, proceed with Power Off Landing procedure
(refer to paragraph 3. 13).
CAUTION
Actuation of the HIGH switch position of the
auxiliary fuel pump after the engine -is opera-
ting normally will cause engine roughness
and/ or power loss.

3.11 ENGINE POWER LOSS IN FLIGHT
Complete engine power loss is usually caused by fuel flow interruption
and power will be restored shortly after fuel flow is restored. The first step is
to prepare for a power off landing (refer to paragraph 3.13). An airspeed of
at least 90 KIAS should be maintained.
If altitude permits, switch the fuel selector to another tank containing
fuel and turn the auxiliary fuel pump on LOW. Reset the mixture control as
I
required and move the induction air to AL TERNA TE. Check the engine
gauges for an indication of the cause of the power loss.
Switch the fuel selector to another tank containing fuel, move induction
air to ALTERNATE and turn the auxiliary fuel pump on LOW.
If power is restored move the induction air to the PRIMARY position
(unless induction ice is suspected). Turn OFF the auxiliary fuel pump and
adjust the mixture control as necessary.
If power is not restored within ten seconds, select auxiliary fuel pump
switch to HIGH, mixture FULL RICH and throttle to approximately 75%
power.
