## 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 LAX94LA222](https://openairdocs.org/ntsb/LAX94LA222), May 21, 1994: Hillberg EH-101 (N10TE), Corona, CA, substantial damage. Probable cause: the pilot's loss of control of the helicopter while hovering downwind. A lack of test-flight data to establish the aircraft's performance limitations was a factor in the accident.
