Transdigm Group Incorporated
A designer and supplier of proprietary aerospace components used in aircraft around the world. Its parts span three segments — Power & Control (engines and power systems), Airframe (cabin and non-power structures), and Non-aviation (ground transport, space, and energy). The company has grown by acquiring dozens of specialized aerospace parts businesses since 1993, and much of its revenue comes from replacement parts and repairs for aircraft already in service.
