Phase of flightThe stage of the flight when things started to go wrong: standing, taxi, takeoff, initial climb, en route, maneuvering, approach or landing. Glossary
Initial climb
Defining eventThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary

NTSB narrative

Two glider pilots were conducting a simulated rope break from 200ft above ground level (AGL). The glider pilot had requested the tow pilot sidestep right on upwind further than normal to allow for enough distance between the upwind leg and the runway. After a normal takeoff, the tow pilot sidestepped further right than the previous flights. After the tow rope was released, the glider pilot made a steep turn back toward the runway and realized that the runway was beyond glide distance. The pilot elected to land the glider in a clear area beside a dirt road, but during the landing, the left wing impacted a tree, resulting in substantial damage to the wing. The pilot reported that there were no mechanical malfunctions or anomalies that would have precluded normal operation.

Probable cause

The check pilot's failure to account for the extended departure distance from the airport during a simulated tow rope break and recovery.

  • 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, 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.
