BASE, STATIC DISCHARGER (P/N 2-21) - New Surplus

The 2-21 is a Chelton static discharger base for mounting static wicks on aircraft structures. This bonded conductive interface attaches to trailing-edge control surfaces, providing a grounded path to dissipate static electricity and reduce radio interference. Compatible with Chelton wick styles on composite or metal airframes.

Installation requires bonding to aircraft structure per FAA AC 43.13-1B grounding and bonding practices to ensure proper electrical conductivity. Verify airframe type and mounting location in the aircraft maintenance manual before installation.
