## 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 LAX92LA162](https://openairdocs.org/ntsb/LAX92LA162), Apr 3, 1992: Robinson R22B (N504RS), Simi Valley, CA, substantial damage. Probable cause: THE INSTRUCTOR PILOT'S DELAYED FLARE FROM THE AUTOROTATION LANDING. A CONTRIBUTING FACTOR WAS THE SOFT NATURE OF THE TERRAIN.
