## 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 CHI04LA145](https://openairdocs.org/ntsb/CHI04LA145), Jun 7, 2004: Betchan KR II (N250KB), Rapid City, SD, destroyed. Probable cause: Failure of the engine rocker arm installation resulting in a loss of engine power. A contributing factor was the power lines.
