4. Flap System Rigging
(PIR-PPS50056-2. Rev. P.)
WARNING: PULL ELECTRIC FLAP CIRCUIT BREAKER, BEFORE BEGINNING.
CAUTION: DO NOT ADJUST PRESET LENGTH OF COMPONENTS UNLESS SPECIFIED BELOW.
A. Before rigging flaps
(1) If necessary, disconnect flap pushrods from wing bellcranks.
(2) Rig flaps before lubricating flap tracks.
(3) Check that the length of the arm assembly (Figure 2) is 14.92 inches. If necessary to reset,
adjust the rod end on arm assembly.
B. Rigging flaps
(1) Check the jack screw set dimension is 0.20 ± 0.06 inches as shown in Figure 2. If adjustment
is necessary, hand turn jack screw by grasping rubber universal on motor shaft.
(2) Check that selector lever is in up (0°) position on instrument panel.
(3) Position limit switches at null point by adjusting clevis end of selector cable.
(4) Set circuit breaker. Motor should not run. Move selector lever to 10° position. Motor should run
and extend jack screw. Return to up position. Jack screw should return to the 0.20 ± 0.06 inch
dimension.
(5) Hold flap trailing edge at approximately W.S. 93.00. Cycle flaps by hand through full travel
several times. Flap rollers should operate smoothly in the track without a tendency to grab or
bind.
(6) Keep flap rollers firmly bottomed out in forward end of center and inboard flap track slots.
Attach flap rods to wing bellcranks. Outboard flap rod is to be snug, allowing no flap end play.
Inboard rod is to be snugged and then tightened one half turn.
