3.11 ENGINE POWER LOSS DURING TAKEOFF (3.Sb) (continued)
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 the Power Off Landing proced ure
(refer to the emergency checklist and paragraph 3.15).
3.13 ENGINE POWER LOSS IN FLIGHT (3.Se)
Complete engine power loss is usually caused by fuel flow interruption
and power will be restored shortly after fuel flow is restored. If power loss
occurs at a low altitude. the first step is to prepare for an emergency landing
(refer to paragraph 3.15). An airspeed of at least 79 KIAS should be
maintained.
If altitude permits. switch the fuel selector to another tank containing
fuel and turn the electric fuel pump to ON. Move the mixture control to ('
RICH and the alternate air to OPEN. Check the engine gauges for an
indication of the cause of the power loss. If no fuel flow/pressure is
indicated. check the tank selector position to be sure it is on a tank
containing fuel.
When power is restored move the alterna te air to the CLOSED position
and turn OFF the electric fuel pump.
If the preceding steps do not restore power, prepare for an emergency
landing.
If time permits, turn the ignition switch to L, then to R. then back to
BOTH. Move the throttle and mixture control levers to different settings.
This may restore power if the problem is too rich or too lean a mixture or if
there is a partial fuel system restriction. Try the other fuel tank. Waterin the
fuel could take some time to be used up, and allowing the engine to windmill
may restore power. If power loss is due to water, fuel flow! pressure
in.dications will be normal. (
