MEASUREMENT OF THE GEARED TRIM TAB/
RIGHT GEAR TAB SURFACES CONVENTIONAL
PLAY (refer to figure 
2-10, sheet 6/11
) , (refer to
figure 
2-10, sheet 5/11
) and (refer to figure 
2-10,
sheet 7/11
) (Cont'd)
A.draw the tangent to the highest point of the
unloading curves (U1 and U2) and of the loading
curves (L1 and L2) up to the intersection with the
surface displacement axis;
B.the backlash value C1 is the distance between the
intersection of the lines U1 and L2 read on the
surface displacement axis;
C.the backlash value C2 is the distance between the
intersection of the lines U2 and L1 read on the
surface displacement axis;
D.the total resulting backlash C is defined as the
mean value between C1 and C2.
7.Check, from the graph, that the backlash C is not
greater than 0.09 in (2.2 mm).
8.Remove the the aileron trim check templates (AGE
NO. 00039) and the comparators (AGE NO. 00062),
from left trim tab /right gear tab surfaces.

ADJUSTMENT OF SPRING TAB (BALANCE TAB)
NEUTRAL POSITION (refer to figure 
2-10, sheet
1/11
) , (refer to figure 
2-10, sheet 2/11
) and (refer
to figure 
2-10, sheet 8/11
)
1.Put the double side adhesive tape on the top surface
of the ailerons and of the tabs, non in contact with
their rivets, and position on it the digital inclinometers
(AGE NO. 00061), parallel to the templates (AGE NO.
00063).
2.Reset the inclinometers (AGE NO. 00061), then
remove the templates (AGE NO. 00063).
