An
autopilot
or
autotrim malfunction occurs when there
is
an
uncommanded deviation
in the
airplane flight path
or
when
there is abnormal control
wheel
or
trim wheel motion. ln
some
cases, and especially for autopilot trim, there may be little
to
no
airplane motion,
yet the red
PITCH
TRIM
annunciator
may
illuminate and an alert
tone may sound.
The
primary concern
in
reacting
to an
autopilot
or
autopilot
trim
malfunction,
or
to
an
automatic disconnect
of
the
autopilot,
is in
maintaining
control
of
the airplane.
lmmediately
grasp the control wheel and press and hold down
the
A/P
DISCÆR|M INT switch throughout the recovery.
Manipulate
the
controls
as
required
to
safely maintain operation
of
the
airplane within
all
of
its
operating limitations. Elevator
trim
should be used manually as needed
to
relieve control
forces.
Locate and
pullthe
AUTOPILOT
circuit
breaker on the
right
hand circuit breaker panel to
completely disable
the
autopilot
system.
2. A
manual electric trim malfunction may be recognized by
the
illumination
of
a
red
PITCH TRIM annunciator
accompanied
by an alert tone,
or by
unusual trim wheel motions with
the
autopilot mode OFF without
pilot
actuation
of the
manual
electric
trim switches. As with an
autopilot malfunction,
the
first concern
following
a
manual electric
trim
malfunction
is
regaining control
of
the airplane.
Grasp
the
control
wheel
firmly and press and hold down
the A/P
DISC/TRIM
INT
switch.
Locate and
pull
the
AUTOPILOT circuit breaker on
the
right hand breaker panel.
3. Note that the
emergency procedure
for any
malfunction
is
essentially
the
same:
immediately grasp
the
control
wheel
and
regain airplane
control while pressing
and holding the
A/P
DISCÆR|M
INT switch down, and retrim
the
airplane
as
needed.
After these steps have been accomplished
secure
the autopilot
electric
trim system by pulling the autopilot
circuit
breaker. As with
any other airplane emergency procedure,
it
is
important that the
4
steps
of
the
Autopilot/Electric
Trim
Emergency Procedures located on Page
13 of
this
supplement
are committed to memory.
