# NTSB investigations: Cessna 170: 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 ANC24LA103](https://openairdocs.org/ntsb/ANC24LA103.md): Cessna 170 · McKinley Village, AK · Accident · No injuries · Class 4 · Limited · Final report · Sep 17, 2024 · N3474C · Substantial damage
  > The pilot’s late decision to go-around, failure to maintain proper airspeed, and his exceedance of the airplane’s critical angle of attack which resulted in an aerodynamic stall at too low of an altitude to recover.
- [NTSB GAA18CA214](https://openairdocs.org/ntsb/GAA18CA214.md): Cessna 170 · Big Lake, AK · Accident · No injuries · Data collection · Final report · Apr 9, 2018 · N4133V · Destroyed
  > The pilot’s exceedance of the airplane’s critical angle of attack, which resulted in an aerodynamic stall.
- [NTSB GAA17CA489](https://openairdocs.org/ntsb/GAA17CA489.md): Cessna 170 · Axtell, KS · Accident · No injuries · Data collection · Final report · Aug 11, 2017 · N4189V · Substantial damage
  > The pilot's exceedance of the airplane's critical angle of attack during a go-around. Contributing to the accident was the pilot's decision to attempt to close a passenger door during a critical phase of flight.
- [NTSB ERA17FA155](https://openairdocs.org/ntsb/ERA17FA155.md): Cessna 170 · Williston, FL · Accident · 4 fatal · Field investigation · Final report · Apr 15, 2017 · N4244V · Destroyed
