Cessna continues to push forward with the certification of the CJ4, the latest model in the CJ line. The company completed the first test flight of the aircraft’s powerplant, the Williams FJ44-4A, last month aboard a company CJ2 flying testbed. The Wichita-based airframer deemed it a success. Williams’s FJ44-4A will feature fadec and produce 3,400 pounds of thrust, almost 800 pounds more than the FJ44-3A. Cessna expects certification of the CJ4 in 2010.
