A glider pilot encountered a loss of lift on base leg, leading to an off-airport landing in a short field. An intentional ground-loop to avoid a fence resulted in substantial damage to the fuselage and right wing.

Incident Overview

A glider pilot reported experiencing a loss of lift while on an extended base leg, approximately 2 miles from the intended airport. Unable to reach the runway, the pilot executed an off-airport landing in a field. The field was too short for a normal rollout, prompting the pilot to intentionally ground-loop the glider to avoid a fence. The terrain was rough, and the maneuver resulted in substantial damage to the fuselage and the right wing.

Pilot Report

The pilot stated that no preimpact mechanical malfunctions or failures occurred with the glider that would have precluded normal operation. The loss of lift was encountered during an extended base leg, and the subsequent landing was performed as a precautionary measure when it became clear the runway could not be reached.

Damage Assessment

The glider sustained substantial damage to its fuselage and right wing due to the rough terrain and the intentional ground-loop. No other damage was reported.
