## 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 LAX93LA348](https://openairdocs.org/ntsb/LAX93LA348), Sep 10, 1993: Robinson R22B (N47NH), Floriston, CA, substantial damage. Probable cause: the flight instructor's failure to maintain main rotor RPM after initiating a go-around from a pinnacle approach. A factor in the accident was the high density altitude condition.
