Inconel-covered Cerachrome Insulation

Missions: Unknown  
Comment: Inconel 718 and A-286 fittings are bolted to
the flanges on the RCC components

This segment of Inconel-covered cerachrome insulation once was bolted to a flange on a reinforced carbon-carbon (RCC) component of the shuttle's leading edge structure and was attached to an aluminum wing spar. It protected the metallic fittings and spar from the heat radiated during reentry from the inside surface of the RCC wing panels. After at least one Space Shuttle mission, this piece was marked Unserviceable (Condemned) and was disposed of as scrap by NASA.
