(c) Measure the resistance.
1) Maximum resistance shall not exceed 300,000 OHMs.
(d) Touch up finish.
NOTE:____ Do not apply anti-static paint to flame sprayed
aluminum.

Install the fasteners which attach the fairing to the structure.
NOTE: Make sure you install the stainless steel bolts and
____ dimpled washers at the same locations on the fairing panel as they were prior to removal of the panels. Installing different hardware in these locations may result in unacceptable electrical bonding.
(a) Torque fasteners to 25-35 lb. inches (2.8-4.0 Nm).
S 764-020-B00
(11) Measure the electrical bonding resistance between conductive fasteners and the fairing panel conductive surface.
NOTE: Maximum resistance shall not exceed 300,000 OHMs for
____ conductive paint.
S 764-040-B00
(12) Maximum resistance shall not exceed 0.5 OHMs for flame spray.
NOTE: Make resistance measurement prior to painting the
____ panel and the mounting hardware. If the fairing panels and bolts have been covered with paint, use sharp probes and make sure the probes contact the conductive finish on the panel and the metal on the mounting hardware. Then you can measure the resistance.
