7.3 In-flight engine starting
- airspeed 75 MPH
- landing site selection SELECT
- master switch ON
- main fuel valve OPEN
- wing tank fuel valves OPEN to tank with most fuel
- choke SWITCH ON (cold engine only)
- throttle - ADJUST to 1/3 of travel
- IDLE (when choke is activated)
- ignition ON
- starter ACTIVATE
- if the engine cannot be restarted, increase the airspeed to 85 – 100 MPH so that air flow can rotate the
propeller, thus enabling engine starting.
For in-flight engine restart, the altitude loss will be about 500 – 650 feet at a minimum
7.4 Fires
Follow these procedures when fire or smoke in the engine compartment or cockpit is detected (though
fires are extremely rare in properly maintained aircraft).
7.4.1 Engine fire on the ground
- main fuel valve CLOSED
- tank fuel valves CLOSED
- throttle FULL – to burn off carburetor fuel
- ignition switch off when engine has stopped as all remaining fuel in
carburetors was burned
- master switch OFF
- abandon the aircraft and extinguish fire (if possible)
- Fire damage INSPECT
Time needed to burn fuel remaining in carburetors after
fuel valves are closed is around 30 seconds.
DO NOT CONDUCT ANOTHER FLIGHT BEFORE THE FIRE CAUSE HAS BEEN
DETERMINED AND REPAIRED BY AUTHORIZED PERSONNEL
7.4.2 Engine fire during take-off roll (still on the ground)
- throttle IDLE
- main fuel valve CLOSED
- brakes apply and STOP the aircraft. Avoid braking so hard that the nose
drops and the propeller hits the ground as this may cause the plane to flip on its nose.
- abandon the aircraft immediately if conditions warrant for safety, otherwise...
- throttle FULL
- ignition switch off when engine has stopped as all remaining fuel in
carburetors has burned
- abandon the aircraft and extinguish fire (if possible)
