DOUBLER (P/N 1213187-2) - New Surplus

The 1213187-2 is an aluminum structural doubler designed to reinforce sheet-metal skins and mounting points in aircraft airframes. This reinforcement plate distributes loads around cutouts, fasteners, and repaired areas to prevent stress concentration and crack propagation. Installed using AN or NAS fasteners per FAA AC 43.13-1B guidance, the doubler bonds to existing skin surfaces to restore structural integrity.

Commonly used in airframe repair work where skin damage requires reinforcement rather than complete panel replacement. Verify part fit and installation procedures against your aircraft's Illustrated Parts Catalog before installation.
