MAINTENANCE MANUAL
E. Pressure Transducer
The pressure transducer is mounted just forward of the aft pressure bulkhead (F.S. 273.75) slightly
to the right of the aircraft centerline and just below the aircraft upper skin. Access is through the
cabin rear closeout panel.
(1) Removal
(a) Disconnect the transducer from the static-system by cutting the Ty-wrap and pulling the
static hose off of the transducer hose barb.
(b) Disconnect the autopilot harness.
(c) Remove screws, washers, and nuts (2 ea.) and remove transducer.
(2) Installation
(a) Place transducer in position on bracket. Secure to bracket with screws, washers, and nuts
(2 ea.)
(b) Slide the static hose over the transducer hose barb and secure with a Ty-wrap.
(c) Connect the autopilot harness.
F. Trim Servo (See Figure 4.)
The trim servo is located on the centerline underneath the baggage compartment floor, just forward
of F.S. 249.60.
(1) Removal
(a) Remove rear seats. Remove carpet and access panels from baggage compartment floor.
(b) Remove the centerline access panels in the cabin floor to expose the plastic tube that
protects the trim cables.
(c) Remove the pins from both ends of the plastic tube.
(d) Slide the tube forward.
(e) Rotate the elevator trim control wheel until the right trim cable turnbuckle clears the aft
end of the tube.
(f) Tie a pull rope to the right trim cable forward of the exposed turnbuckle.
(g) Tie a pull rope to the right trim cable aft of the idler pulley.
(h) Tie-off both pull ropes to maintain tension on the left trim cable and the extreme forward
and aft segments of the right trim cable (i.e. - forward of the turnbuckle and aft of the idler
pulley).
NOTE: Tension must be applied to the trim cables to prevent the cables from unwrapping
from the trim wheel drum or the trim actuator, and to prevent the cables from
fouling at any of the pulleys.
(i) Slack off the exposed turnbuckle to relieve tension on the right trim cable segment
between the turnbuckle and idler pulley.
(j) Disconnect the autopilot harness.
(k) Remove the capstan cover and cable guards (4) by removing the retaining screws (4).
(l) Remove the bolt, nut, and washer securing the idler pulley to the trim servo baseplate and
mounting bracket and remove the idler pulley components.
NOTE: The idler pulley breaks down into the following components upon removal of the
bolt, above: mounting plate/cable guard assembly, idler pulley, and two washers.
(m) Remove the remaining bolts, nuts, and washers (3 ea.) securing the trim servo to its
mounting bracket and remove the trim servo.
