PIPER CHEROKEE WARRIOR SERVICE MANUAL
5. Attach the cable end to the tension chain (20) and secure with bushings, clevis bolt, nut and
cotter pin. If the chain is not installed because of the torque tube assembly being removed, install the assembly
as given in step a, 7.
6. Pull the flap handle (29) full back and connect the tension spring (22) to the cable end.
d. Install the tunnel cover and secure with screws. Also, the tunnel carpet and bracket cover.
e. Install and secure the seats.
5-40. RIGGING AND ADJUSTMENT OF WING FLAPS.
Do not rotate the torque tube while adjusting cable tension or
tighten enough to allow tube to be pulled away from its stops.
a. Place the flap handle in the full forward position. (Flaps Up)
b. If not previously removed, remove the bottom half of the rear seat.
c. Adjust the flap up stop and step lock as follows:
1. Loosen the jam nut of the right torque tube stop screw, located in the floor opening along the
outer end of the flap torque tube
2. Turn the stop screw to obtain approximately 0.60 inch between the stop fitting and the bearing
block as measured along the top side of the screw. (Refer to Figure 5-22.) It may be necessary to loosen the
left stop adjustment screw.
3. Place a 0.125 inch spacer between the stop fitting and the end of the screw.
Check that, when pressure is applied down on the flap, it will
remain in the up lock position. If it extends, turn the adjust -
ment screw out a few threads at a time until the flap remains
in the up lock position with the spacer inserted. Tighten the
jam nut.
4. Rotate the left stop adjustment screw until it contacts the stop fitting. Tighten the jam nut.
5 . Set the flap control cable tension (handle next to floor, 0 degrees) as given in Table V-II at
t u r nbuckle attached to the low end of the flap handle in the floor tunnel. (Remove the flap handle cover and
enough tunnel carpet to remove the tunnel cover just aft of the handle)
6. Adjust and safety the turnbuckle.
d. To check up (0° position) of the flaps, place a flap rigging tool as shown in Figure 5-23 against the
underside of the wing and flap as close as possible to the outboard end of the flap without contacting any
r i vets. The tool must be positioned parallel with the wing ribs with the aft end of the tool even with the trailing
edge of the flap. (This tool may be fabricated from dimensions given in Figure 5-26.)
e. With the flap control rod connected between the torque tube crank arm and the flap, check that the
surface of the wing contacts the tool at its forward surface and at the spacer, and the aft end of the flap contacts
the aft end of the tool. The flap is neutral at this position.
f If the three points do not contact, loosen the jam nuts on each end of the control rod and rotate the
rod until the three points contact. Apply a slight up pressure against the trailing edge of the flap while making
this adjustment. After adjustment, tighten jam nuts.
