Aileron Controls; Removal Of Aileron Control Cables - Piper Lance II Service Manual

LANCE II SERVICE MANUAL
6. Loosen the connecting bolts (3) of the idler sprockets (15 and 18) to allow the
chain to fit snug around the control wheel sprockets and over the idler sprockets.
7. Connect the aileron control cables (22) to the ends of the chains (14 and 16)
with bolts, bushings, nuts and cotter pins (19).
8. Adjust the chain turnbuckle (6) between the two control wheel sprockets to
allow the control wheels to be neutral and obtain proper cable tension as given in Table V-I.
It may be necessary in order to have both control wheels neutral to set the chain turnbuckle
to neutralize the wheels and then set cable tension with the turnbuckles located under the
floor panel aft of the main spar as instructed in Paragraph 5-11. Before safetying the
turnbuckle, check that when the ailerons are neutral, the control wheels will be neutral and
the chain turnbuckle centered. Also the aileron bellcranks should contact their stops before
the control wheel hits its stop. Maintain .030 to .040 clearance between sprocket pin and
adjustable stop bolts on models having adjustable tee bar stops.
9. Set stabilator cable tension with the turnbuckle in the aft section of the fuselage
and instruction given in Paragraph 5-15. Check safety of all turnbuckles upon completion of
adjustments.
10. Tighten the connecting bolts (3) of the idler sprockets (15 and 18).
11. Install the floor tunnel plate and secure with screws. Fasten the tunnel carpet in
place.
b. Either control wheel assembly may be installed by the following procedure:
1. Insert the control wheel tube through the instrument panel.
2. Should wires for the various Autopilot systems need to be installed in the
control tube, route them through the hole in the forward side of the tube and out of the
small hole in the side. Position the rubber grommet in the hole in the side of the tube.
3. On the left control tube, install the stop (12).
4. Connect the control wheel tube (4) to the flexible joint (2) of the tee bar
assembly. If the control cables and/or chains have not been removed or loosened, place the
ailerons in neutral and install the control tube on the flexible joint to allow the control
wheel to be neutral. Install bolt, washer and nut (3) and tighten.

5-7. REMOVAL OF AILERON CONTROL CABLES. (Refer to Figure 5-2.)
a. For the removal of any of the control cables in the fuselage or wings, first remove
the floor panel that is located directly aft of the main spar by removing the center seats, seat
belt attachments and the screws securing the panel. Lift the panel and remove the airplane.
b. To remove either the right or left primary control cables (14 and 15) that are
located in the fuselage, the following procedure may be used:
1. Remove the fuel selector panel cover by removing the rudder trim knob and the
cover attachment screws.
2. Remove the lower selector cover and disconnect the fuel selector control lever
from the selector torque tube by removing the attachment pin located at the bottom of the
lever.
3. Remove the tunnel plate just aft of the tee bar by laying back enough tunnel
carpet to remove the plate attachment screws.
4. Remove the forward heat duct from one side of the floor tunnel (preferably
from the side from which the cable is to be removed) by removing the trim control wheel
cover, the heater baffles from the side of the duct, the floor carpet and the duct attachment
screws.
