## NTSB investigations (6)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.

- [NTSB ERA26LA199](https://openairdocs.org/ntsb/ERA26LA199), Apr 20, 2026: Alexander Schleicher ASW 27-18 (N27CU), Greenwood, SC, substantial damage. Probable cause: The glider pilot’s encounter with a strong sink/loss of lift, which resulted in a forced landing to unsuitable terrain.
- [NTSB ERA24LA119](https://openairdocs.org/ntsb/ERA24LA119), Feb 15, 2024: Alexander Schleicher ASW 27-18 (N429SH), Polk City, FL, substantial damage. Probable cause: The glider pilot’s misjudged altitude, which resulted in an off-airport landing and collision with a fence.

Probable cause: The pilot’s failure to maintain the glider’s stability in the roll axis during the takeoff roll, which resulted in a dragged wingtip and ground loop.
- [NTSB WPR20LA216](https://openairdocs.org/ntsb/WPR20LA216), Jul 11, 2020: Schleicher ASW27 (N167TM), Ely, NV, destroyed, 1 fatal. Probable cause: The pilot’s loss of glider control while maneuvering near a mountain ridge in downdrafts and dry microbursts at an altitude that precluded recovery.
- [NTSB CEN10LA459](https://openairdocs.org/ntsb/CEN10LA459), Aug 4, 2010: Alexander Schleicher ASW 27-18 (N8829A), Batesville, TX, substantial damage, 1 fatal. Probable cause: Both glider pilots' inability to see and avoid the other resulting in a mid-air collision.
