## Other investigations on N4754R (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 LAX00LA100](https://openairdocs.org/ntsb/LAX00LA100), Feb 16, 2000: Bell 47G5 (N4754R), Riverbank, CA, substantial damage. Probable cause: the pilot's failure to verify that ground personnel had disconnected the loading hose from the hopper before takeoff, resulting in restricted directional control and a hard landing.
