PROCEDURE:
2-67.1
CHECK OF FLAP CONTROL CABLE TENSION
(refer to figure
) , (refer to figure
)
1.Lock the forward quadrant (3) on the frame No. 3 by
inserting a rigging pin (1) (AGE NO. 00181) dia. 8
mm.
2.Insert a rigging pin (5) (AGE NO. 00181) dia. 4.915
mm in the last quadrant (4) located in the centre wing.
3.Lock the tension regulator (6) by locking tool.
4.Stretch the flap control cables (2) , by means of two
turnbuckles at frame No. 11, at a load of 360 N (twice
the nominal preload).
5.Remove the rigging pins (1 and 5) (AGE NO. 00181)
from the forward quadrant (3) and from the quadrant
(4) located in center wing.
6.On the FCS1 control panel move the flap control lever
from UP to DOWN position and viceversa, performing
25 cycles at least.
7.Set the pre-load to 180 N after that the rigging pin (1)
(AGE NO. 00181) has been inserted in forward
quadrant (3) on frame No. 3 and verifyng that enters
freely in the last quadrant.
WARNING

8.Remove the locking tool from the tension regulator
and check the flap control cables (1) are stretched in
accordance with the equations:
