11. Engine cleanup - Perform.
NOTE
At V yse, speeds, holding three to five degrees
bank (one-half ball width) towards the
operating engine will assist in maintainin
directional control and improve aircraft
performance.
f. Engine Malfunction During Final Approach. If
an engine malfunctions during final
LANDING CHECK) the propeller
approach (after
should not be
manually feathered unless time and altitude permit or
conditions require it. Continue approach using the
following procedure:
1. Power-As required
2. Gear - DN.
g. Engine Malfunction (Second Engine). If the
second engine fails, do not feather the propeller if an
engine restart is to be attempted. Engine restart without
starter assist can not be accomp lished with a feathered
propeller, and the propeller Will not unfeather without
the engine operating
best all around glid
140 KIAS is recommended as the
e speed (considering engine restart,
distance covered, transition to landing configuration,
etc.), although it does not necessarily result in the
minimum rate of descent. Perform the following
procedure if the second engine fails during cruise flight.
1. Airspeed - 140 KIAS.
2. Powerlever - IDLE
3. Propeller lever - Do not FEATHER.
4.
Conduct engine restart procedure.
h. Engine Shutdown In Flight. If it becomes
necessary to shut an engine down during flight, perform
the following:
1.
Power lever - IDLE.
2.
Propeller lever - FEATHER.
3.
Condition lever - FUEL CUTOFF.
4.
Engine clean up - Perform.
i. Engine Cleanup. The clean
used after engine malfunction,
unsuccessful restart is as follows:
1.
Autoignition switch - OFF.
2.
Autofeather switch - OFF.
3.
Generator switch - OFF.

j. Engine Restart During Flight Using Starter.
Engine restarts may be attempted at all altitudes. If
restart is attempted, perform the following:
1.
2.
3.
4.
5.

7.
8.
9.
Cabin temperature mode selector switch - OFF.
Electrical load - Reduce to minimum.
Fire pull handle - In.
Power lever - IDLE.
Propeller lever - FEATHER.
Condition lever - FUEL CUTOFF.
TGT (operative engine) - 700°C or less.
Ignition and engine start switch - ON.
Condition lever - LOW IDLE.
NOTE
If a rise in TGT does not occur within 10
seconds after moving the condition lever to
LOW IDLE, abort the start.
10. TGT - Monitor (1,000°C for 5 seconds
maximum).
11. Oil pressure - Check.
12. Ignition and engine start switch - OFF at 50%
N1.
13. Generator switch - RESET, then ON.
14. Engine cleanup - Perform if engine restart
unsuccessful.
15. Cabin temperature mode selector switch - As
required.
16. Electrical equipment - As required.
17. Autoignition switch - ARM.
18. Propellers - Synchronize.
19. Power - As required.
k. Engine Restart During Flight (Not Using
Starter). A restart without starter assist may be
accomplished provided airspeed is at or above 140
KIAS altitude is below 20,000 feet, and the propeller is
not feathered. If altitude permits, diving the aircraft will
increase N1 and assist in restart. N1 required for airstart
should be at or above 9%. If a start is attempted,
perform following:
1.
Cabin temperature mode selector switch - OFF.
