A Boeing-compiled list determined that 2,051 lives were lost in 22 accidents in the years 1998 – 2007 due to LOC accidents . NTSB data for 1994 – 2003 count 32 accidents and more than 2,100 lives lost worldwide . Loss of control as a factor in aviation accidents came into the spotlight with the 1994 crash of USAir Flight 427 , which killed all 127 passengers and 5 crew members on board . In their report on the crash , the U.S. NTSB stated that prior to the crash they " ... had issued a series of safety recommendations over a 24-year period , asking the FAA to require air carriers to train pilots in recoveries from unusual flight attitudes . Throughout this period , the Safety Board was generally not satisfied with the FAA ’s responses to these recommendations ; specifically , the Board disagreed with the FAA ’s responses that cited the inadequacy of flight simulators as a reason for not providing pilots with the requested training . However , after the USAir Flight 427 accident and the October 31 , 1994 , ATR-72 accident involving American Eagle Flight 4184 near Roselawn , Indiana , the FAA issued guidance to air carriers , acknowledging the value of flight simulator training in unusual attitude recoveries and encouraging air carriers to voluntarily provide this training to their pilots . " Some carriers did implement their own voluntary training programs , following those accidents , and the NTSB regarded those programs as " excellent . " In October 1996 , the NTSB issued a formal Safety Recommendation ( A-96-120 ) , which requested the FAA to require all airlines to provide simulator training for flight crews , which would enable them to recognize and recover from " unusual attitudes and upset maneuvers , including upsets that occur while the aircraft is being controlled by automatic flight control systems , and unusual attitudes that result from flight control malfunctions and uncommanded flight control surface movements . " In 2004 , the U.S. FAA issued its first '' Airplane Upset Recovery Training Aid '' . The second revision of that document was released in 2008 and is available at the FAA 's website
