## Other investigations on N6567 (3)

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 CEN11LA556](https://openairdocs.org/ntsb/CEN11LA556), Aug 18, 2011: Grumman G-164A (N6567), El Campo, TX, substantial damage. Probable cause: Separation of the No. 3 cylinder exhaust valve rocker arm, which resulted in a loss of engine power.
