Tailwind During Touch-and-Go Results in Runway Excursion and Nose-Over (N471AM)

On March 31, 2006, an Aviat A-1B (registration N471AM) was involved in an aviation accident near Driggs, ID. Investigators recorded the probable cause as: The pilot's failure to maintain directional control during the landing roll, which resulted in a loss of control and subsequent nose over.
