## Other investigations on N2791P (5)

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 ANC20CA041](https://openairdocs.org/ntsb/ANC20CA041), Apr 7, 2020: Piper PA 18A (N2791P), Chickaloon, AK, substantial damage. Probable cause: The pilot's selection of unsuitable terrain for landing, which necessitated a go-around, and her subsequent failure to maintain clearance from rising mountainous terrain.
- [NTSB GAA17CA027](https://openairdocs.org/ntsb/GAA17CA027), Oct 14, 2016: Piper PA18 (N2791P), Palmer, AK, substantial damage. Probable cause: The airplane's encounter with a depression while the pilot applied excessive braking during the landing roll on a grass airstrip, which resulted in a nose-over.
