## 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 CHI97LA231](https://openairdocs.org/ntsb/CHI97LA231), Jul 28, 1997: Stratton Challenger II (N44LS), Bellaire, MI, destroyed, 1 fatal. Probable cause: failure of the pilot to maintain control of the airplane during takeoff. The gusty wind condition was a related factor.
