Cessna has confirmed its 182 JT-A powered by an SMA diesel engine landed in a field 30 miles west-northwest of Wichita Aug. 21. It is used for research and development of the diesel-powered 182. No details as yet but a local television station reported an engine failure. The pilot onboard was not injured and apparently was alone in the aircraft. Television news footage shows the aircraft intact amidst tall grass. The aircraft was on a certification flight. It was one of the steps needed to complete certification before deliveries can begin. Congratulations to the pilot for a great emergency landing.
