ADP.ma LLC

ADPma is an OEM and FAA-PMA aftermarket supplier of precision proprietary aircraft parts for commercial aviation and defense. It was founded more than twenty years ago in the East Tennessee foothills of the Appalachian Mountains and works from Piney Flats. The company designs, engineers, certifies, manufactures and sells its own parts and components, aimed at cutting maintenance cost and improving reliability for airlines, OEMs, cargo operators, MROs, distributors, resellers and leasing companies.

History and direction

The company says it began as a small start-up that survived by finding a way to say yes to any opportunity, and that this approach produced its wide range of capabilities and its network of manufacturing partners. ADPma has recently been acquired by "buy and grow" private investors who plan long term expansion. Its stated aim is to grow across airlines, OEM, MRO, cargo, business and general aviation, lessors, defense and space, and it describes itself as open to selective mergers and acquisitions that add technologies or skills.

PMA and OEM work

The company states that airlines worldwide have approved its PMA parts as configuration standards for maintenance. Its PMA work is presented as more than cost saving: it looks for gains in service, reliability and parts availability, and it concentrates on new PMA development from its own intellectual property. As an OEM-side business it takes responsibility for mature and non-core products under license or acquisition, so the original maker can focus on current programs. It specializes in low volume, high mix manufacturing, from out-of-production legacy items to new designs. It says over 100 airlines in 39 countries use its parts, with more than half a million of them in service.
