2-71.5 CHECK OF FLAP TRAVEL AND CLEARANCE
(refer to figure
) , (refer to figure

(refer to figure
) (Cont'd)
19.Insert a 0.193 in (4.915 mm) diameter rigging pin
(AGE NO. 00181) in the differential lever at rib 24 of
right and left outer wings.
20.Check that the clearance between outer flaps and
ailerons is 0.314 thru 0.787 in (8 thru 20 mm).
21.Remove 0.193 in (4.915 mm) diameter rigpin, bring
control lever to FULL position, lower LH aileron until
alignment with LH outer flap.
22.Check that horizontal clearance between aileron and
flap in down position is greater than or equal to 0.196
in (5 mm).
23.Repeat the check on RH outer wing. The results must
be the same.
24.Retract the flaps to 0°.
25.Remove the inclinometers (AGE NO. 00061) and the
adhesive tapes.
26.Release hydraulic pressure in No. 1 and No. 2
systems.
2-71.6 MEASUREMENT OF FLAP CONTROL FRICTION
FORCE (refer to figure
) and (refer
to figure
1.Pull flap control lever (4) from grooved sector and
keep it free by inserting a spacer.
2.Apply a 22.045 lb (10 kg) dynamometer (AGE NO.
00034) (5) to the end of the flap control lever (4) and
measure the maneuver force required to move the
lever from UP to FULL. The maneuver force must not
exceed 19.841 lb (9 kg).
3.Remove the spacer mentioned in step 1. and the
dynamometer (AGE NO. 00034) mentioned in step 2.
