National Transportation Safety Board Acting Chairman Mark V. Rosenker says improving runway safety, crew resource management, and addressing human fatigue will enhance safety in business aviation. In an address to the 2008 Bombardier Safety Standdown in Kansas City, MO, Rosenker cited the NTSB's review of accident trends and the potential for human error in emphasizing the importance of these safety areas. He said the industry can reduce accidents caused by human fatigue by setting work hour limits for flight crews, aviation mechanics and air traffic controllers based on fatigue research, circadian rhythms, and sleep and rest requirements. While advocating the adoption of measures designed to address these issues, Rosenker also indicated that regulation is not the only way to improve safety. "I believe that voluntary action by industry, in partnership with the government, is one of the most effective ways to decrease accidents.”
