The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The pilot's overreaction to a perceived conflict with a tow plane and glider on an intersecting runway, which resulted in a loss of control during an attempted aborted landing. Contributing to the accident was the failure of the glider tow operator to follow and the airport operator to ensure compliance with published airport rules and regulations for glider tow operations..
