LEAD (P/N 137490b410) - New Surplus

Part 137490b410 is a flexible bonding lead for aircraft electrical grounding and equipotential continuity. This conductive cable connects removable panels, access doors, and structural components to the airframe, maintaining continuous current paths during lightning strikes and static discharge events. The lead follows SAE AS3360 specifications for aerospace bonding applications.

Installation requires matching the correct length and termination style to mating points per aircraft maintenance manual procedures. Properly installed bonding leads prevent voltage differentials between structures and protect avionics and fuel system components from electrical damage.
