## Other investigations on N66607 (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 CHI00LA285](https://openairdocs.org/ntsb/CHI00LA285), Sep 2, 2000: Boeing Stearman B75N1 (N66607), Cape Girardeau, MO, substantial damage. Probable cause: the pilot's improper decision to continue the flight when the fuel sight gauge indicated empty and the exhausted fuel supply. A factor was the corn crop.
