## NTSB investigations (3)

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 WPR23FA223](https://openairdocs.org/ntsb/WPR23FA223), Jun 10, 2023: Compagnie Daher TB 30 Epsilon (N759F), Apache Junction, AZ, destroyed, 2 fatal. Probable cause: The pilot’s controlled flight into the mountainous terrain due to diminished depth perception as a result of the shadowing effect from the sun’s position. Contributing to the accident was the…
