## NTSB investigations (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 CEN19LA045](https://openairdocs.org/ntsb/CEN19LA045), Dec 15, 2018: Brandt Sonex (N393SX), Lodi, WI, substantial damage. Probable cause: The pilot's failure to maintain proper alignment with the runway during final approach, which resulted in impact with a tree.
