2.4 Electrical Bonding
For the purposes of this STC, aircraft ground reference definitions vary according to airframe
type as defined in Table 2-2. Refer to the periodic test and reconditioned resistance values
corresponding to these ground reference definitions when performing the equipment bonding
tests in Section 4.5.
The periodic test value is the value allowed during the bonding checks specified in Section 4.5.
The reconditioned value is the value allowed on initial installation or if the bond must be
reworked if the periodic test value is exceeded.
Refer to SAE ARP 1870 Section 5 when surface preparation is required to achieve electrical
bond.
