What happened
On June 15, 2017, a Burkhart Grob G103C glider, registration N103GH, was on final approach for landing in Boerne, Texas. While approximately 100 feet above the ground, a sink rate began to develop. The flight instructor took control of the aircraft and closed the spoilers in an attempt to correct the descent.
Despite these actions, the aircraft struck the airport perimeter fence and landed short of the runway. Following the impact, the glider slid into a culvert. There were no injuries resulting from the accident, though the aircraft sustained substantial damage to the empennage.
The investigation
The investigation noted that the flight instructor did not submit the required NTSB Form 6120.1 Pilot/Operator Aircraft Accident/Incident Report.
