Flight Stream 210 Bonding Strap

The following removal and replacement steps are provided as guidance for replacing the Flight Stream 210
bonding strap. The bonding strap assembly drawing is shown in Figure 6-14.
NOTE
The aircraft structure side of the bonding strap may be mounted using a nut in lieu of a nut
plate. If a nut was used in lieu of a nut plate, further disassembly of the aircraft may be
required to gain access to the nut.
Removal
1. Disconnect one end of the bonding strap from the aircraft ground location.
2. Disconnect the other end of the bonding strap from the shield block on the Flight Stream 210
connector backshell.
3. Remove the bonding strap.
Replacement
NOTE
The Flight Stream 210 bonding strap should be as short as practical and must not exceed
20 inches. When installed, the bonding strap must not loop back on itself.
1. Construct a bonding strap no longer than 20 inches by attaching 10 AWG terminal lugs to both
ends of 1/4" braid (QQB575R36T0250) or wider.
2. If needed, clean the attachment locations with a bonding brush.
3. Secure each end of the bonding strap to the previously installed locations. Ensure that the strap
does not loop back on itself and that the hardware is as shown in Figure 6-14. The washers must
seat fully against the aircraft metallic structure without overhang or interference from other
hardware.
4. Using a milliohm meter, verify that the bonding resistance is less than or equal to 10 mΩ.
In the event of a bonding test failure, remove the bonding strap from the aircraft ground point and clean the
attachment point with a bonding brush. Re-install the bonding strap and perform the electrical bonding test
in accordance with Section 4.5 again.
