## Other investigations on N8870Q (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 CEN16FA328](https://openairdocs.org/ntsb/CEN16FA328), Aug 19, 2016: Aero Commander S2R (N8870Q), Center, CO, destroyed, 1 fatal. Probable cause: The pilot's failure to maintain airplane control during a low-level maneuver, which resulted in an aerodynamic stall.
- [NTSB SEA02LA166](https://openairdocs.org/ntsb/SEA02LA166), Aug 21, 2002: Aero Commander S2R Thrush (N8870Q), Connell, WA, substantial damage. Probable cause: The pilot's failure to adequately compensate for wind conditions and his failure to maintain directional control. Factors include rough uneven terrain.
