What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Aircraft was on a training flight, when the instructor was demonstrating an auto-rotation for the student. During the procedure, the aircraft entered a dust-devil inadvertently which caused the aircraft to settle at a rate that could not be arrested prior to contact with the ground. Once the aircraft contacted the ground the aircraft rolled over causing the main rotor to strike the ground. (.19) on July 27, 2002, about 1330 mountain standard time, a Robinson R22 beta, N232DR, was substantially damaged during a hard landing from a practice autorotation in a farm field near Prescott, Arizona.
