SECTION 3 PIPER AIRCRAFT CORPORATION
EMERGENCY PROCEDURES PA-28-181, ARCHER II
If sufficient altitude has been gained to attempt a restart, maintain a safe
airspeed and switch the fuel selector to another tank containing fuel. Check
the electric fuel pump to insure that it is ON and that the mixture is RICH.
The carburetor heat should be ON and the primer checked to insure that it is
locked.
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 procedure
(refer to the emergency check list and Paragraph 3.13).
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. If power loss
occurs at a low altitude, the first step is to prepare for an emergency landing
(refer to Paragraph 3.13). An airspeed of at least 76 KIAS should be
maintained.
If altitude permits, switch the fuel selector to another tank containing
fuel and turn the electric fuel pump ON. Move the mixture control to RICH
and the carburetor heat to ON. Check the engine gauges for an indication of
the cause of the power loss. Check to insure the primer is locked. If no fuel
pressure is indicated, check the tank selector position to be sure it is on a
tank containing fuel.
When power is restored move the carburetor heat to the OFF 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 other fuel tanks, Water in 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 pressure indications
will be normal.
