BONDING LEAD (P/N 137490b412) - New Surplus

The 137490b412 is an aircraft bonding lead that creates a low-impedance electrical path between aircraft structures. This component equalizes electrical potential across control surfaces, hinges, and structural joints to mitigate static discharge, electromagnetic interference, and lightning strike effects. Installed across control-surface hinges and movable components, the bonding lead maintains electrical continuity during flight operations.

Termination points require secure attachment with contact surfaces cleaned per FAA AC 43.13-1B specifications. Installation torque and routing follow the applicable aircraft maintenance manual to ensure proper grounding and structural integrity.
