## Latest cases

- [NTSB CEN24LA246](https://openairdocs.org/ntsb/CEN24LA246.md): Air Tractor AT-402 · Helm, MS · Accident · No injuries · Class 4 · Limited · Final report · Jun 30, 2024 · N9185K · Substantial damage
  > The pilot’s failure to maintain control, which resulted in an aerodynamic stall and impact with terrain.
- [NTSB CEN24LA216](https://openairdocs.org/ntsb/CEN24LA216.md): Air Tractor AT-402 · Perryton, TX · Accident · Serious injuries · Class 4 · Limited · Final report · Jun 6, 2024 · N45123 · Destroyed
  > The pilot’s exceedance of the airplane’s critical angle of attack during a low-level turn, which resulted in an aerodynamic stall and loss of airplane control at too low of an altitude to recover.
- [NTSB WPR20CA313](https://openairdocs.org/ntsb/WPR20CA313.md): Air Tractor AT 402 · Somerton, AZ · Accident · No injuries · Class 4 · Data collection · Final report · Sep 20, 2020 · N45027 · Destroyed
  > The pilot’s failure to use full power during takeoff and his delayed decision to abort the takeoff, which resulted in a runway overrun and subsequent impact with terrain.
- [NTSB GAA19CA010](https://openairdocs.org/ntsb/GAA19CA010.md): Air Tractor AT 402 · Crowley, LA · Accident · No injuries · Data collection · Final report · Oct 8, 2018 · N1500E · Substantial damage
