develop manifold pressure above ambient pressure. The engine will
revert to "normally aspirated" and can be operated, but will produce
less than its rated horsepower.
If turbocharger failure occurs before
takeoff, do not fly the aircraft. If a failure occurs in flight, readjust
mixture as necessary to obtain fuel flow appropriate to manifold air
pressure and RPM
.
WARNING
The cabin pressurization system operates from
bleed air supplied by the turbochargers. Cabin
pressure will quickly fall if the turbochargers fail.
WARNING
If turbocharger failure is a result of a loose,
disconnected or burned-through exhaust, a
serious fire hazard exists. If turbocharger failure
occurs before takeoff, DO NOT fly the aircraft. If
failure occurs in flight, and the choice is made to
continue operating the engine, proceed as follows:
NOTE
At altitudes above 15,000 feet an over rich mixture
may result if the turbocharger fails and the engine
may quit operating. If this occurs, employ the
following procedure:
1 Mixture
IDLE
CUTOFF
2 Throttle
FULL
3 Propeller CRUISE
RPM
4 Throttle
CRUISE
POSITION
5 Mixture
Advance slowly. When the
proper mixture ratio is reached,
the engine will start. Continue to
adjust the mixture control unit
until the correct fuel flow for the
manifold pressure and RPM is
obtained.
NOTE
An interruption in fuel flow to the engine can
cause engine power loss due to turbocharger
"run-down". At high altitude, merely restoring
fuel flow may not cause the engine to restart,
because the mixture will be excessively rich. If the
engine does not restart, there will be insufficient
mass flow through the exhaust to turn the turbine.
This condition may give indications similar to a
