## 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 WPR13FA335](https://openairdocs.org/ntsb/WPR13FA335), Jul 22, 2013: Mooney M20C (N6709U), South Lake Tahoe, CA, substantial damage, 1 fatal. Probable cause: The pilot’s decision to turn into rising terrain that would have required performance in excess of the airplane’s maximum climb rate to clear after taking off at a high density altitude.
