Suspected Turbocharger or Exhaust System Failure
WARNINGS:
1. IF A TURBOCHARGER FAILURE IS A RESULT OF A LOOSE, DISCONNECTED
OR BURNED THROUGH EXHAUST SYSTEM A SERIOUS FIRE HAZARD
EXISTS. IF A FAILURE OF THE EXHAUST SYSTEM IS SUSPECTED IN
FLIGHT, OR INDICATIONS OF A FIRE OCCUR, SHUT DOWN THE ENGINE
AND LAND AS SOON AS POSSIBLE.
2. IF A SUSPECTED EXHAUST SYSTEM FAILURE OCCURS BEFORE TAKEOFF,
DO NOT FLY THE AIRCRAFT.
3. A TURBOCHARGER MALFUNCTION AT ALTITUDE COULD RESULT IN
AN OVERLY RICH MIXTURE WHICH COULD CAUSE A PARTIAL POWER
LOSS AND ROUGH RUNNING ENGINE OR A COMPLETE LOSS OF ENGINE
POWER.
Complete Loss Of Engine Power
If a suspected turbocharger or turbocharger waste gate control system failure results in a complete
loss of engine power the following procedure is recommended:
Mixture ...............................................IDLE CUT OFF
Throttle ..............................................CRUISE
Propeller ...........................................FULL FINE
Mixture ..............................................ADVANCE slowly until engine re-starts
If Engine Re-starts:
Continue Flight, but ...........................LAND AS SOON AS PRACTICAL
If Engine Does Not Re-start:
Forced Landing ..................................CARRY OUT - Refer paragraph 3.3.2
Partial Loss Of Engine Power
If turbocharger waste gate control fails in the OPEN position, a partial loss of engine power may
result. The following procedure is recommended if a suspected turbocharger waste gate control
failure results in a partial loss of engine power.
Throttle ...............................................AS REQUIRED
Propeller ............................................AS REQUIRED
Mixture ...............................................AS REQUIRED

Engine Power Overboost
If the turbocharger waste gate control fails in the CLOSED position, an engine power over-boost
condition may be experienced. The following procedure is recommended in this case.
Throttle ...............................................REDUCE as necessary to keep manifold pressure within limits
NOTE:
