(3) The KANDU must be electrically bonded to the airframe through contact with the base of the
unit as follows:
• At least one of the two provided mechanical attachm
ent points for electrical bonding
must be used for bonding the KANDU to the airframe. Make sure that the all mating
surfaces in the bonding path are free from contaminants such as paints or other
non-conductive elements.
• One 0.65 inch (16.5 mm) diameter circular and one 0.65
inch (16.5 mm) diameter
by 1.02 inch (25.9 mm)diameter elongated conductive area is provided around two
of the mounting holes of the equipment base plate.
• The KANDU includes a 0.59 inch (15 mm) diameter bonding measuring point on one
of th
e attachment tabs, close to the bonding element, but not on the bonding
element.
KANDU bonding to the aircraft must be achieved
through the mounting structure (fasteners)
and KANDU A3J1-A.
The KANDU bonding resistance measured from the measuring point and the surface the unit
is mounted must be less than 2.5 mΩ.
4.4 Installation Guidelines for the A791 Based AIM (If applicable)
The skirt fairing comes attached to the ARINC 791 based AIM plate. The installation sequence suggested
for mounting A791 based AIM is as follows:
• Install the A791 based AIM bonding straps.
• Install the A791 based AIM fittings to the aircraft fuselage.
• Mount the A791 based AIM.
• Install the A791 based AIM bonding straps to the A791 based AIM assembly.
Before putting the A791 based AIM assembly onto aircraft, install bonding straps to the aircraft fittings.
Refer to the airframe specific kits and assembly drawings for fastener details. Figure 4-1 shows a typical
ground strap connection.
