The NTSB's narrative final · quoted from the NTSB record

The pilot encountered turbulence that continued to increase while entering the pattern for landing. On final approach, the pilot added power to counteract the turbulent wind condition. The trike continued to experience turbulence and the pilot decided to descend rapidly once past the runway numbers in hopes of finding smoother air. At this point, she still felt that she had control of the trike. About 50 feet above the ground; however, a gust of wind struck the trike and pushed it off the runway centerline. She corrected back to the runway, and at this point the trike became uncontrollable and impacted the runway in a nose-down attitude. The pilot stated that there were no mechanical problems with the trike at the time of the accident.
