## NTSB investigations (1)

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 DEN04CA085](https://openairdocs.org/ntsb/DEN04CA085), Jun 3, 2004: Let Blanik L-13 (N99860), Durango, CO, substantial damage. Probable cause: the pilot's improper in-flight planning and decision and his failure to maintain adequate terrain clearance. Contributing to the accident was the lack of suitable terrain, and the low approach.
