Evolution Trikes REVO N9912S accident near Newark, Illinois

Probable cause

The student pilot's failure to maintain directional control on landing. Contributing to the accident was the pilot's lack of flight experience.

NTSB analysis

The student pilot was conducting his fourth solo flight in the weight-shift aircraft and was landing on a private turf runway in light wind conditions. A witness stated that the aircraft initially appeared to track straight down the runway after landing; however, shortly thereafter, it started to oscillate to the left and right. The oscillations increased until the aircraft rolled over and came to rest on its side. An examination of the aircraft did not reveal any preimpact malfunctions or anomalies that would have precluded normal operation. Although the pilot only had a total of 16.75 flight hours and less than 2 hours solo, it could not be determined why he lost control of the aircraft after landing.
