STANDARD PROCEDURES
1.
STOPPING ENGINES
When operating under high ambient temperature conditions engine shut down by mixture
alone may not be positive.
Shutting down the engine under these conditions should be as follows:
i:
Pull the mixture controls to idle cut-off.
Depress button left side of quadrant.
C.
Pull back the throttles and hold until engine stops.

This airplane is certified as a normal category airplane and must be operated in compliance
with the Airplane Flight Manual. Acrobatic Maneuvers (including spins) are prohibited. Stalls and
slow flight should be performed only in accordance with the Airplane’ Flight Manual.
Avoid abrupt maneuvers. Maneuvers at speeds and weights in excess of maneuvering speeds
and loadings listed under Limitations Section of this Airplane Flight Manual may subject the
airplane to load factors beyond which it is certificated.
Maintain at least 5000 feet of terrain clearance when practicing stalls.
3.
SPINS
c
All spins are prohibited, however in the event an unintentional spin.is encountered recovery
can be accomplished by immediately using the following procedures:
a. Retard both throttles to the idle position.
b. Apply full rudder in the opposite direction to the spin.
C.
Push control wheel full forward. While it is not necessary for recovery, the use of
ailerons against the turn (i.e. right aileron if spin is to the left) will expedite recovery.
d. Maintain controls in these positions until the spin stops. Then neutralize rudder and
ailerons.

movement should be used during recovery from the dive, as the maneuvering speed and positive
