Removal and installation
Before installing the bonding remove the paint coat which protects the joint. Principles for
repeated installation of the bonding:
(a) Carefully clean the whole bonding including the washers, bolts and nuts from all
impurities, if necessary degrease the contacting surfaces on the connecting material.
(b) Carefully check whether wires of bonding band are not torn off. Change the damaged
band.
(c) Carefully clean and degrease contacting surfaces on the airplane structure. Clean
corroded surfaces with emery paper to the metallic luster.
CAUTION:
IF A NEW PART WAS INSTALLED INTO THE AIRPLANE, ITS SURFACE IS
PROVIDED BY NON-CONDUCTIVE SURFACE PROTECTION (FOR
EXAMPLE ANODIZING), THIS SURFACE PROTECTION MUST BE
REMOVED FROM THE AREA OF BONDING INSTALLATION.
(d) The threaded joints, which fulfill a function of bonding, cannot be lubricated.
(e) On the same areas of the airplane structure install the same type of bonding which you
removed.
(f) After repeated bonding installation coat the remaining metallically clean surface of the
contact area, as well as protruding heads of bolts and nuts with protective paint.

Installing clamps by Nicopress pliers
Procedure of clamp installation by Nicopress pliers is shown on the Fig. 15-10.
First pull the cable through the clamp, make a loop around the thumb and pull the cable end
back through the clamp. The cable end should overlap by about 32 mm (
1.25 in
) from the
clamp after its puling through. The overlapping will ensure that the cable end will not be
pulled back into the clamp during the clamp squeezing. Before actual squeezing the clamp
it is also necessary to verify which cable terminal will be used, whether thimble or
suspension eye, because some terminals must be put into the cable before actual clamp
squeezing.
