Glasflugel STANDARD LIBELLE accident near Fields, Oregon, July 25, 2024

On July 25, 2024 at about 8:30 pm local time, a 1968 Glasflugel STANDARD LIBELLE (glider), registered N1599, was substantially damaged in an accident during landing near Fields, Oregon. It was a personal flight under general aviation rules (Part 91). No one was hurt; 1 person was on board or involved. The weather was visual conditions (good weather).

The NTSB's probable cause their words, unchanged

The glider’s encounter with a gusting wind and downdraft conditions, which resulted in exceedance of the glider’s critical angle of attack, an aerodynamic stall, and a hard landing.

The NTSB's narrative final · quoted from the NTSB record

The pilot of the glider reported that desert storm fronts had been moving in and out of the area during her flight. When the wind increased, and the glider was unable to maintain or regain altitude due to an absence of thermal activity the pilot elected to land off airport between two approaching storms. The pilot lowered the nose to maintain airspeed; however, during the landing flare, the glider encountered a gusting wind and a downdraft, which resulted in an aerodynamic stall about 3-4 ft above the ground. The glider then landed hard, resulting in substantial damage to the fuselage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the glider that would have precluded normal operation.
