NTSB narrative
The pilot reported that while departing, the airplane climbed to an altitude of 20 feet above the ground. The airspeed began decreasing, and the airplane started descending. The pilot pitched down as the stall warning sounded. The airplane impacted the terrain, collapsing the nose wheel and substantially damaging the left wing. The pilot stated the airplane had encountered windshear and that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
Probable cause
The pilot’s loss of airplane control after an encounter with windshear during takeoff which resulted in collision with terrain.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, coordinates, cause areas. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
