## 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 LAX97LA055](https://openairdocs.org/ntsb/LAX97LA055), Nov 28, 1996: Cessna 170A (N1729D), El Cajon, CA, substantial damage. Probable cause: failure of the pilot to maintain directional control, which resulted in a ground swerve. The pilot's low total time in conventional gear aircraft was a related factor.

## FAA accident and incident reports (1)

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.
