NTSB summary
HISTORY OF FLIGHTOn June 1, 2014, about 1222 central daylight time, a Yakovlev YAK-55M airplane, N176FD, was substantially damaged when it impacted terrain during an aerobatic flight over the Stevens Point Municipal Airport (STE), Stevens Point, Wisconsin. The airline transport pilot was fatally injured. The airplane was registered to and operated by the pilot under the provisions of 14 Code of Federal Regulations (CFR) Part 91 without a flight plan.

The airplane then rolled upright before entering a 90° turn away from show center and the crowd. The airplane continued to climb as it turned to a heading opposite that of the takeoff runway, turned back to the runway heading, and reentered the aerobatic box. The airplane rolled inverted before it entered a 45° dive toward show center. The airplane then completed several descending aileron rolls before it rolled wings level and entered a near vertical climb. At the apex of the climb/loop, the airplane entered an inverted flat spin.

Probable cause
