LANCE II SERVICE MANUAL
b. With each
bellcrank set at neutral, the ailerons
may be checked and adjusted
for
neutral as follows:
1.
Ascertain that the bellcrank rigging
tool fits snug between the bellcrank
and the
rib.
2. Place
an aileron rigging
tool as shown in
Figure 5-4 against
the underside of
the
wing and aileron as close as possible to the inboard end of the aileron without contacting any
rivets. The tool must be positioned
parallel with the wing ribs with
the aft end of the tool even
with the trailing edge
of the aileron. (This tool may be fabricated
from dimensions given in
Figure 5-19.)
3. With the aileron control
rod connected between the bellcrank
and aileron, check
that the surface of the
wing contacts the tool at its forward
surface and at the spacer, and the
trailing edge
of the flap contacts the aft end of the
tool. The aileron may be allowed to droop
approximately 1/8" inch at
the inboard trailing edge. The aileron
is neutral at this position.
4.
Should the three points not contact,
loosen the jam nut at the aft
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 aileron while
making this adjustment. After adjustment
retighten the
jam nut.
c. Adjust primary and balance
cable tension as given in Table
V-I, by the following
procedure:
1. 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.
2. Loosen the
connecting bolts
of the idler cross-over
sprockets at
the control tee
bar to allow the chain to fit snug
around the control wheel sprockets
and over the idler
sprockets.
3. Ascertain
that both bellcranks are at
neutral position.
4. Adjust the turnbuckles,
located in the floor opening aft
of the main spar, of the
primary and balance
cables to proper cable tension and maintain
neutral-center position of the
control wheels. Primary cable tension
will be slightly less than balance
cable tension, but
should be within the tension
specified. Adjust the cables so that when
the specified tension is
reached, the inboard ends
of the ailerons are visually aligned with
the outboard ends of the
flaps.
Maintain a light "up" pressure on the
middle of the underside of the aileron when
making
this observation, to
take the slack out of the hinge and linkage.
To obtain neutral position of
both control wheels, it may also be
necessary to adjust the roller chain
turnbuckle located
between the
control wheel sprockets. During adjustment
obtain a little more tension on
the
primary control cables to hold
the bellcranks in neutral against the
rigging tools, finishing with
even tension on all cables.
5. Tighten the bolts
to secure the idler cross-over
sprockets.
6.
Remove the
aileron bellcrank
rigging
tool from each
wing.
d. Check the ailerons
for correct travel from neutral per
dimensions given in Table V-I,
by the following procedure:
1. Center the bubble of a protractor
over the surface of an aileron
at neutral
position
and note
the reading.
2.
Move the aileron
full up and down,
and check
the degree of travel
for each
direction. When measuring
the full down position, apply a
light "up" pressure to the center of
the aft edge of the aileron. When measuring
the full up position, apply a light
"down" pressure
to the center of the aft edge of the
aileron. This pressure should be just sufficient
enough to
remove the
slack between the bellcrank and the aileron.
The degree of travel on the protractor
is determined by taking the
difference between the protractor reading
at neutral and up, and
neutral
and down.
The bubble
must be centered
at each
reading.
