## Other investigations on N2534V (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 SEA04LA050](https://openairdocs.org/ntsb/SEA04LA050), Mar 1, 2004: Cessna 170 (N2534V), Herron, WA, destroyed, 2 fatal. Probable cause: The failure of the left muffler while maneuvering, resulting in a carbon monoxide leak into the cabin rendering the pilot incapacitated, and the subsequent uncontrolled descent and impact with water.
- [NTSB SEA98LA075](https://openairdocs.org/ntsb/SEA98LA075), May 17, 1998: Cessna 170 (N2534V), Auburn, WA, substantial damage. Probable cause: The pilot's inadequate compensation for gusty crosswind conditions. A related factor was gusty crosswinds.
