Williams International launched the 3,500-pound-thrust FJ44-4, a FADEC-equipped turbofan engine that uses essentially the same core as the 3,000-pound-thrust FJ44-3. Detailed performance parameters are being kept under tight wraps until an application for the new engine is announced. A spokesman for Williams International, based in Walled Lake, Mich., said at the show the company is just now beginning to market the engine to potential OEMs. Williams-powered aircraft on display at Orlando Executive Airport during the show included the Cessna Citation CJ1, CJ2 and CJ3, Beech Premier I, Sino Swearingen SJ30-2, Adam A700 and Spirit Wing Learjet 25D.
