## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19760621016709A](https://openairdocs.org/incident/19760621016709A), Jun 21, 1976: Grumav G164A, Covington, TN, Substantial damage. Carb butterfly shaft sheared.

## Other investigations on N7951 (2)

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 CEN15LA204](https://openairdocs.org/ntsb/CEN15LA204), Apr 15, 2015: Grumman G 164A (N7951), Maysville, OK, substantial damage. Probable cause: The loss of engine power for reasons that could not be determined because a postaccident examination of the airframe and engine did not reveal any anomalies that would have precluded normal operation.
- [NTSB SEA98LA140](https://openairdocs.org/ntsb/SEA98LA140), Jul 17, 1998: Grumman-Schweizer G-164A (N7951), Caldwell, ID, substantial damage. Probable cause: The pilot-in-command's misjudgment of clearance with a power line, resulting in a collision with the line. Factors included a power line and dark night light conditions in the spray area.
