# NTSB investigations: American AA-1A: Aerodynamic stall/spin

NTSB aviation accident and incident investigations since 1962: the probable cause, findings, aircraft, crew, weather and docket of each, linked to the FAA registry and the FAA’s own reports.

## Latest cases

- [NTSB CEN22FA203](https://openairdocs.org/ntsb/CEN22FA203.md): American AA-1A · Cleburne, TX · Accident · 1 fatal · Class 3 · Field · Final report · May 17, 2022 · N6409L · Substantial damage
  > The student pilot’s decision to operate the airplane after consuming alcohol, which led to an exceedance of the airplane’s critical angle of attack, an aerodynamic stall, and a subsequent loss of control at a low altitude.
- [NTSB CEN21FA290](https://openairdocs.org/ntsb/CEN21FA290.md): American AA-1A · Cleburne, TX · Accident · 2 fatal · Class 3 · Field · Final report · Jun 24, 2021 · N9261L · Destroyed
  > The canopy moving fully open during flight, which resulted in the pilot’s distraction and a subsequent aerodynamic stall/spin and loss of control.
- [NTSB WPR14FA239](https://openairdocs.org/ntsb/WPR14FA239.md): American AA-1A · El Mirage, CA · Accident · 2 fatal · Field investigation · Final report · Jun 9, 2014 · N9454L · Destroyed
  > The pilot's loss of airplane control while intentionally maneuvering close to the ground, which resulted in the airplane exceeding its critical angle of attack in a steep bank and entering an accelerated stall.
- [NTSB WPR11FA344](https://openairdocs.org/ntsb/WPR11FA344.md): American AA-1A · Corona, CA · Accident · 2 fatal · Field investigation · Final report · Jul 23, 2011 · N34299 · Substantial damage
