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 (3.3a)
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.
Turn OFF the emergency fuel pump. The fuel selector valve should be
OFF and the mixture at idle cut-off if an external fire extinguishing method is
to be used.
3.8
TURBOCHARGER FAILURE (3.3b)
If a turbocharger failure is the result of loose, disconnected or
burned through exhaust system components, a potentially
serious fire hazard exists as well as the risk of carbon monoxide
migration into the passenger compartment of the aircraft. If a
failure within the exhaust system is suspected in flight,
immediately reduce power to idle (or as low a power setting as
possible) and LAND AS SOON AS POSSIBLE. If a suspected
exhaust system failure occurs prior to takeoff, DO NOT FLY
THE AIRCRAFT.
A turbocharger malfunction may result in an overly rich fuel
mixture, which could result in a partial power loss and/or a rough
running engine. In worst-case conditions a complete loss of
engine power may result.
