Castleberry Instruments & Avionics provides truly outstanding products, frequently unavailable for older aircraft installation. Units are FAA approved and TSO’d replacements for older, popular components, no longer manufactured elsewhere. This diverse product line replaces products that are no longer available from the original manufacturer and that are increasingly difficult to repair or overhaul due to their age and lack of repair parts. Castleberry products embody a heritage of quality and reliability brought by a core of professionals with an average of more than 20-years in the industry and offer one of the industry’s best warranties.
