NTSB narrative

The pilot reported that while on downwind he elected to land on the grass runway parallel to the asphalt runway. As he crossed the threshold for the landing area, he realized he was landing onto a grass field next to the grass runway. With the glider too low to transition to the grass runway, the pilot continued to land onto the field. During the landing sequence, the glider impacted two culverts and sustained substantial damage to the fiberglass fuselage. The pilot reported no preimpact mechanical failures or malfunctions that would preclude normal operation of the glider.

Probable cause

The pilot's failure to identify the proper landing surface which resulted in an off airstrip landing and collision with rough 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. 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.
