NTSB Factual Report

During takeoff from a grass runway, the aircraft's landing gear encountered a wet and soft area of runway. Due to the encounter with the wet and soft terrain, the pilot was unable to get the aircraft airborne. The aircraft "slowed down very fast" and the left wing tip impacted terrain. The wing sustained substantial damage and was reported to be "not repairable." The pilot did not report any mechanical problems with the aircraft.

NTSB Probable Cause

The pilot's inadequate preflight preparation, which led to the inability to accelerate to takeoff speed after encountering wet and soft runway conditions.
