## 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 CHI94LA323](https://openairdocs.org/ntsb/CHI94LA323), Sep 9, 1994: Beech D18S (N666S), Mt Pleasant, MI, substantial damage. Probable cause: the improper fuel selector position by the pilot-in-command which resulted in fuel starvation. A factor was rough/uneven terrain.
