Aircraft are matched to registry aircraft by N-number and event date; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. - [NTSB WPR26LA158](https://openairdocs.org/ntsb/WPR26LA158), Apr 13, 2026: Alexander Schleicher ASH 31 MI (N77UK), Williams, CA, substantial damage, investigation ongoing - [NTSB CEN23FA391](https://openairdocs.org/ntsb/CEN23FA391), Aug 31, 2023: Schleicher Alexander ASH 26 E (N50FU), Wellington, CO, substantial damage, 1 fatal. Probable cause: The pilot’s loss of glider control during approach for reasons that could not be determined, which resulted in an aerodynamic stall at an altitude too low for recovery. - [NTSB WPR23LA245](https://openairdocs.org/ntsb/WPR23LA245), Jun 26, 2023: Schleicher Alexander ASH 26 E (N26DX), Williams, CA, substantial damage. Probable cause: The pilot’s encounter with atmospheric conditions where the lift was not sufficient to maintain flight, which resulted in a collision with terrain. - [NTSB GAA17CA386](https://openairdocs.org/ntsb/GAA17CA386), Jul 5, 2017: Alexander Schleicher ASH 31 MI (N31MX), Ely, NV, destroyed. Probable cause: The pilot’s failure to maintain the proper airspeed and his exceedance of the glider’s critical angle of attack, which resulted in a stall/spin. - [NTSB ERA13CA310](https://openairdocs.org/ntsb/ERA13CA310), Apr 12, 2013: Schleicher Alexander ASH 26 E (N26EL), Tullahoma, TN, substantial damage.
