(1) Remove any sign of grease or oil contamination with a MISCELLANEOUS (Material No. 19-003) moist with CLEANING AGENTS (Material No. 11-004).
4. Procedure
_________ Subtask 20-28-00-912-063
A. Antistatic Protection of the Surface of Non-Conductive Components (Kevlar or Glass Cloth). (Ref. Fig. 214/TASK 20-28-00-991-001, 215/TASK 20-28-00-991-034, 216/TASK 20-28-00-991-035, 217/TASK 20-28-00-991-036)
(1) Non-conductive components protected with antistatic paint.
(a) Get the electrical continuity of the external surface :
-directly with the antistatic paint below the fastener when this fastener is installed at the edge of the panel.
-with a bonding lead connected to the structure when the fastener is not installed at the edge of the panel. In all cases, put a conductive insert or washer between the antistatic paint and the fastener.
(2) Do a check of the electrical resistance (Ref. TASK 20-28-00-869-002). Subtask 20-28-00-912-064
B. Antistatic Protection of the Surface of Conductive Components.
(Ref. Fig. 218/TASK 20-28-00-991-002)
(1)
The fastener makes a path for the electrical continuity directly from the external surface to the structure.
(2)
Do a check of the electrical resistance (Ref. TASK 20-28-00-869-002).
