## 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.

- [NTSB ERA16LA130](https://openairdocs.org/ntsb/ERA16LA130), Mar 14, 2016: Grumman Acft ENG Cor-Schweizer G-164 (N6654K), Myakka, FL, substantial damage. Probable cause: A total loss of engine power for reasons that could not be determined because postaccident examination of the engine revealed no mechanical anomalies that would have precluded normal operation.
