Probable cause

The pilot's failure to maintain adequate airspeed while maneuvering at low altitude, which resulted in an aerodynamic stall.

Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that he had completed one low approach in the weight-shift-controlled airplane and was making a second low approach at a slower speed and lower altitude. As the airplane started to climb after the low approach, the passenger asked the pilot if the airplane could be maneuvered to the left to avoid trees on the right side. The pilot stated that he began a turn to the left, and the airplane lost lift and speed. He attempted to recover, but the airplane struck a corn crop. The airplane sustained substantial damage to the wing. The pilot reported no preaccident mechanical malfunctions or failures of the airplane that would have precluded normal operation. He stated that the accident was avoidable and was due to pilot error.
