ENGINE FAILURE (Continued)
A flameout can result from the engine running out of fuel, or by unstable
engine operation. Unstable engine operation such as a compressor
surge, possible due to a bleed valve malfunction, can be identifiable by
an audible popping noise just before flameout. Once the fuel supply
has been restored to the engine or cause of unstable engine operation
eliminated, the engine can be restarted.
The best airstart technique is to initiate the restart procedure
immediately after a engine failure occurs, provided the pilot is certain
that the engine failure was not the result of some malfunction that might
make it hazardous to attempt a restart.
Regardless of airspeed or altitude, there is always the possibility that
the engine can restart successfully just as soon as the IGNITION is
switched ON. In an emergency, turn the IGNITION switch ON just as
soon as possible after engine failure, provided the N
g
speed has not
dropped below 50%. Under these circumstances, it is not necessary to
shut off the fuel or feather the propeller. The POWER lever, however,
should be set to the IDLE position.
The pilot should determine the reason for power loss
before attempting an airstart.
If a engine failure has occurred and the Ng speed has dropped below
50%, the FUEL CONDITION lever should be moved to the CUTOFF
position before an airstart is attempted.
Propeller feathering is dependent on circumstances and is at the
discretion of the pilot. However, if engine OIL PSI drops below 15 PSI,
the propeller should be feathered.
