## 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 FTW93LA231](https://openairdocs.org/ntsb/FTW93LA231), Aug 6, 1993: Cessna 172RG (N9633B), Salida, CO, destroyed. Probable cause: THE CLIMB CAPABILITY OF THE AIRPLANE BEING EXCEEDED AND THE PILOT'S DECISION TO TURN INTO THE RISING TERRAIN. A FACTOR WAS THE HIGH DENSITY ALTITUDE.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
