NTSB Narrative Summary Released at Completion of Accident

The pilot was performing a pull up during aerobatics when he heard a bang and then felt a left rolling tendency. Postaccident examination of the experimental amateur built airplane revealed that the lower left wing exhibited upwards twisting which extended on an inclination from the wing root to a point on the wing's leading edge forward of the wing strut and then on a declination to the wing tip. The pilot's student pilot/medical certificate was expired.

NTSB Probable Cause Narrative

the in-flight deformation of the left wing.
