## The NTSB's investigation of this event (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.

Probable cause: The partial loss of engine power for reasons that could not be determined because postaccident testing and examination did not reveal any anomalies that would have precluded normal operation.
