## 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 LAX90LA227](https://openairdocs.org/ntsb/LAX90LA227), Jun 23, 1990: Robinson R22A (N84378), Pinon Hills, CA, substantial damage. Probable cause: THE PILOT'S FAILURE TO MAINTAIN ADEQUATE ROTOR RPM DURING AN ATTEMPTED TAKEOFF. A CONTRIBUTING FACTOR WAS THE HIGH DENSITY ALTITUDE.
