## Other investigations on N7843 (4)

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 CEN13LA533](https://openairdocs.org/ntsb/CEN13LA533), Sep 6, 2013: Grumman G-164A (N7843), Atlantic, IA, destroyed. Probable cause: The pilot’s delay in releasing product to reduce the airplane’s weight and improve its climb performance, which was reduced because of the high density altitude.
- [NTSB FTW83LA107](https://openairdocs.org/ntsb/FTW83LA107), Jan 8, 1983: Grumman G164A-450 (N7843), Clyde, TX, substantial damage
