## Latest cases

- [NTSB CEN20LA309](https://openairdocs.org/ntsb/CEN20LA309.md): Cessna A188 · Corsica, SD · Accident · 1 fatal · Class 3 · Limited · Final report · Jul 27, 2020 · N53163 · Destroyed
  > The pilot’s exceedance of the airplane’s critical angle of attack, which resulted in an aerodynamic stall and loss of control.
- [NTSB CEN20CA086](https://openairdocs.org/ntsb/CEN20CA086.md): Cessna 182 · Huron, SD · Accident · No injuries · Data collection · Final report · Feb 15, 2020 · N2019A · Substantial damage
  > The pilot's failure to maintain adequate airspeed during final approach, which resulted in the airplane exceeding its critical angle of attack and a subsequent aerodynamic stall at too low of an altitude to recover.
- [NTSB CEN19LA049](https://openairdocs.org/ntsb/CEN19LA049.md): Beech 58 · Sioux Falls, SD · Accident · 2 fatal · Class 2 · Limited · Final report · Dec 25, 2018 · N6745V · Destroyed
