## Other investigations on N7737G (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 IAD97FA014](https://openairdocs.org/ntsb/IAD97FA014), Oct 30, 1996: Cessna 172L (N7737G), Brandy Station, VA, destroyed, 2 fatal. Probable cause: the certificated flight instructor's failure to ensure that proper altitude/clearance was maintained above the terrain and trees, while on final approach. Darkness was a related factor.
