## 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 LAX95LA289](https://openairdocs.org/ntsb/LAX95LA289), Aug 12, 1995: Ronneberg/Murphy Berkut (N91DR), Santa Paula, CA, destroyed, 1 fatal. Probable cause: the pilot's inadvertent entry into an accelerated stall in a maximum performance high-g turn at an altitude insufficient to recover aircraft control prior to colliding with the ground.

## FAA accident and incident reports (2)

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.
