4. Fold the end of the tape over twice for added thickness at the prepared grounding location.
5. If a bonding strap will be used to reach the grounding location, secure the end of the tape to the
composite surface with an 0.063 in.-thick aluminum strip and three bolts and nuts, as shown in
figure 4-10.
6. Make sure that the resistance between tape and the local grounding location does not exceed
2.5mΩ.
7. Attach the aluminum tape to the transponder mounting rack.
8. Verify that the resistance between the mating surfaces does not exceed 2.5 mΩ. Verify the total
resistance from transponder chassis to instrument panel or aircraft ground reference does not
exceed the reconditioned value shown in table 3-13.
