be less for a given propeller RPM compared to the primary induction air system. This is due to
loss of ram effect and induction of warmer inlet air.
The following check list should be used if a
partial power loss
due to primary induction air sys-
tem blockage is experienced:
Alternate Air

NOTE:
The alternate air door should open automatically when primary induction system
is restricted. If alternate air door has not opened (Annunciator light--OFF) it can
be opened manually by pulling alternate air control.

TURBOCHARGER FAILURE
--WARNING--
If turbocharger failure is a result of a loose, disconnected or burned through ex-
haust, than a serious fire hazard exists. If a failure in the exhaust system is sus-
pected in flight, shut down the engine and LAND AS SOON AS POSSIBLE. If a
suspected exhaust system failure occurs before takeoff, DO NOT FLY THE AIR-
CRAFT.
Turbocharger failure may be evidenced by the inability of the engine to develop manifold air
pressure above the ambient pressure. The engine will revert to “normally aspirated” mode and
can be operated but will produce less than rated horsepower. If turbocharger failure occurs be-
fore 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.
