# NTSB investigations, TN: 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 ERA22FA391](https://openairdocs.org/ntsb/ERA22FA391.md): Aeronca 7AC · Jacksboro, TN · Accident · 1 fatal · Class 3 · Field · Final report · Aug 29, 2022 · N1478E · Destroyed
  > The pilot's exceedance of the airplane’s critical angle of attack during takeoff, which resulted in an aerodynamic stall and loss of control.
- [NTSB GAA19CA527](https://openairdocs.org/ntsb/GAA19CA527.md): Diamond DA20 · Convington, TN · Accident · No injuries · Data collection · Final report · Aug 31, 2019 · N98BZ · Substantial damage
  > The student pilot's improper pitch attitude during the takeoff climb, and the flight instructor's delayed remedial action which resulted in an aerodynamic stall and ground impact.
- [NTSB ERA17CA137](https://openairdocs.org/ntsb/ERA17CA137.md): Cirrus Design SR20 · Cleveland, TN · Accident · No injuries · Data collection · Final report · Mar 26, 2017 · N782JR · Substantial damage
  > The flight instructor's inadequate supervision, which resulted in a premature rotation for a no-flap takeoff and subsequent loss of airplane control during the initial climb.
- [NTSB ERA17LA048](https://openairdocs.org/ntsb/ERA17LA048.md): Schweizer SGS126 · Moscow, TN · Accident · Serious injuries · Limited investigation · Final report · Nov 17, 2016 · N65968 · Substantial damage
  > The pilot's failure to maintain adequate airspeed and his exceedance of the glider’s critical angle of attack while maneuvering at low altitude, which resulted in an aerodynamic stall/spin.
- [NTSB ERA13LA320](https://openairdocs.org/ntsb/ERA13LA320.md): Thompson Bruce D Sonerai II · Pulaski, TN · Accident · 1 fatal · Limited investigation · Final report · Jul 16, 2013 · N788T · Destroyed
  > The pilot's failure to maintain airspeed during a near-vertical climb after takeoff, which resulted in an aerodynamic stall and subsequent collision with terrain.
- [NTSB ERA12CA321](https://openairdocs.org/ntsb/ERA12CA321.md): Eiriavion PIK 20D · Eagleville, TN · Accident · Serious injuries · Data collection · Final report · May 6, 2012 · N39RB · Substantial damage
  > The glider’s encounter with atmospheric lift conditions not sufficient to maintain flight, which resulted in an aerodynamic stall.
- [NTSB ERA12CA015](https://openairdocs.org/ntsb/ERA12CA015.md): Piper PA-18-150 · Elizabethton, TN · Accident · Minor injuries · Data collection · Final report · Oct 7, 2011 · N3491Z · Substantial damage
  > The failure of the pilot to maintain airspeed during the initial climb after takeoff, which resulted in an aerodynamic stall.
