TRIM SYSTEM
General
This aircraft is
equipped with a command
trim system designed
to
withstand any type of
single
malfunction, either mechanical
or
electrical, without
uncontrolled
operation resulting. The preflight
check procedure
is designed to uncover hidden failures that might
otherwise
go
undetected.
Proper
operation of the electric trim
system
is predicated
on conducting the following preflight check
before each flight. If the trim
system
fails any portion
of the pro-
cedure,
pull the tiim circuit breaker
out until triin
system
is
re-
paired. Substitution of any trim system component for another
model is not authorized.
For emergency
interrupt information,
refer
to Emergency
Procedures
section of this Supplement.
The command
electric trim switch on the left hand portion of the
pilot's control wheel has two functions:
(1)
When the top
bar (AP OFF)
is'pressed, it disconnects
the
autopilot.
(2)
When the top
bar is pressed AND the rocker is moved forward,
nose
down trim will occur, when moved aft, nose
up
trim
will
occur.
