2. Ensure the existing ground location is prepared in accordance with Appendix Section B.2.

3. Route the aluminum tape between the GTS 8XX install rack and the grounding location. If needed

to maintain the length-to-width ratio, the tape width can be overlapped in more than one strip. If

two or more pieces of tape must be joined end-to-end, they can be joined as illustrated in

Figure B-5.

4. Fold the end of the tape over twice for added thickness at the prepared grounding location. The

span of the fold should equal or exceed the width of the aluminum plate used to protect the

aluminum tape from the fasteners.

5. Secure the end of the tape to the composite surface with the existing aluminum plate, as shown in

Figure B-6.

6. If any of the existing special bonding components are found to be damaged, use the braid and

hardware specified in Table B-1 to replace the damaged items (see Figure B-6 and Figure B-7).

The bonding strap must not be longer than six inches.

7. If multiple strips of tape were used, the plate must touch each strip to ensure grounding.

8. Ensure the bonding straps, aluminum plate, and associated hardware are re-installed as shown in

Figure B-6.

9. Verify the resistance between tape and the local grounding location does not exceed 2.5 mΩ.

10. Re-install the GTS 8XX install rack and aluminum plate on the aluminum tape as shown in

Figure B-7.

11. Verify the resistance between the GTS 8XX chassis and the aircraft ground structure listed in

Table 2-2 does not exceed the value specified.
