## Other investigations on N8505F (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 CHI05CA147](https://openairdocs.org/ntsb/CHI05CA147), May 19, 2005: Bell 47G (N8505F), Twin Brooks, SD, substantial damage. Probable cause: The pilot's inadequate lookout and his failure to maintain clearance with the power lines. A factor was the low altitude at which the helicopter was operating.
