## Other investigations on N7763K (2)

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 ANC11CA082](https://openairdocs.org/ntsb/ANC11CA082), Aug 18, 2011: Piper PA-20 (N7763K), Tyonek, AK, substantial damage. Probable cause: The student pilot’s decision to take off toward a hill with a gusting tailwind. Contributing was the pilot's premature rotation that prevented the airplane from climbing over the hill.
