3.5 AMPLIFIED EMERGENCY PROCEDURES (GENERAL)

The following paragraphs are presented to supply additional information for the purpose of providing
the pilot with a more complete understanding of the recommended course of action and probable cause of
an emergency situation.

3.7 ENGINE FIRE DURING START

Engine fires during start are usually the result of overpriming. The first attempt to extinguish the fire
is to try to start the engine and draw the excess fuel back into the induction system.
If a fire is present before the engine has started, move the mixture control to idle cut-off, open the
throttle and crank the engine. This is an attempt to draw the fire back into the engine.
If the engine has started, continue operating to try to pull the fire into the engine.
In either case (above), if fire continues more than a few seconds, the fire should be extinguished by
the best available external means.
The fuel selector valves should be "OFF" and the mixture at idle cut-off if an external fire
extinguishing method is to be used.

3.9 ENGINE POWER LOSS DURING TAKEOFF

The proper action to be taken if loss of power occurs during takeoff will depend on the circumstances
of the particular situation.
If sufficient runway remains to complete a normal landing, land straight ahead.
If insufficient runway remains, maintain a safe airspeed and make only a shallow turn if necessary to
avoid obstructions. Use of flaps depends on the circumstances. Normally, flaps should be fully extended for
touchdown.
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 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).
