BONDING LEAD (P/N 137490b411) - New Surplus

The 137490b411 is a flexible braided bonding lead that establishes low-impedance electrical continuity between aircraft structures. This copper or aluminum conductor with braided shielding provides a static dissipation and lightning return path, preventing electrical potential buildup between components. Installed between access panels and the airframe to maintain structural bonding integrity.

Installation requires short lead length with clean metal-to-metal terminations per MS25083 standards and FAA AC 43.13-1B guidance. Critical for airworthiness in bonding systems.
