Wing resumes T-6A flying operations Published Dec. 5, 2017 71st Flying Training Wing Public Affairs VANCE AIR FORCE BASE, Okla. - The 71st Flying Training Wing at Vance Air Force Base, Oklahoma, resumed T-6A Texan II flying operations Dec. 5 following four physiological events which occurred between Nov. 1 and Nov. 15. No specific root cause for the physiological events was identified during two weeks of investigation by aviation, medical, functional and industry experts. However, specific concerns were eliminated as possible causes including maintenance and aircrew flight equipment procedures. As technical and human performance data continues to be gathered, the Vance team will temporarily apply local procedures to mitigate risk to flight operations and aircrew. "The cross functional cooperation between agencies spanning the Department of Defense and industry has been outstanding," said Col. Darrell F. Judy, 71st Flight Training Wing commander. "We are actively using lessons learned across the aeronautics enterprise to determine the cause of these events, and are confident implementing mitigation techniques will enable us to return to our primary mission of training the world's finest aviators."
