MTU management was authorized, given certain launch conditions for MTU, to take shares in envisioned engine programs for business and regional aircraft. MTU intends to take about a 15 percent stake in each of its partner Pratt & Whitney's envisioned engine programs. If these programs go forward, they will be worth to MTU some $17 billion in revenue, during the life of the programs. These would include the following engines: PWX10 engine (10,000 pound thrust category) for emerging medium-sized and large business jets. MTU estimates that nearly 4,000 engines of the type will be produced during the life of the program; Geared turbofan engine for the Mitsubishi Regional Jet, which is expected to be launched in 2008 (15,000 to 17,000 pound thrust category; estimated market volume about 1,500 engines); Geared turbofan engine (23,000 pound thrust category; estimated market volume about 3,000 engines) for Bombardier's CSeries regional aircraft, which is expected to be launched in 2008.
