Primary finding
Probable cause
improper planning/decision by the pilot, which led to a snag and sudden slack in the tow rope, and necessitated an aborted launch (emergency landing) after initial liftoff. This in turn led to an inadvertent stall, a wing drop, and the left wing tip dragging the ground. A factor relating to the accident was: the restricted movement of the tow rope after it became snagged on the crop stubble.
