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 GAA19CA287](https://openairdocs.org/ntsb/GAA19CA287.md): Jihlavan Airplanes Sro KP5 · East Haddam, CT · Accident · No injuries · Data collection · Final report · May 25, 2019 · N235KP · Substantial damage
  > The pilot's failure to maintain the proper airspeed and his exceedance of the airplane's critical angle of attack during takeoff, which resulted in an aerodynamic stall.
- [NTSB ERA17FA272](https://openairdocs.org/ntsb/ERA17FA272.md): Cessna 172 · New Milford, CT · Accident · 1 fatal · Field investigation · Final report · Aug 11, 2017 · N1727V · Substantial damage
  > The flight instructor's failure to ensure that the wing flaps were properly configured for takeoff, which resulted in an aerodynamic stall and loss of control during the initial climb.
- [NTSB ERA17LA261](https://openairdocs.org/ntsb/ERA17LA261.md): Cessna 172 · Danbury, CT · Accident · 1 fatal · Limited investigation · Final report · Jul 30, 2017 · N612DF · Substantial damage
  > The pilot's exceedance of the airplane's critical angle of attack during initial climb, which resulted in an aerodynamic stall. Contributing to the accident was the pilot's decision to operate the airplane above its maximum gross weight, which likely reduced…
- [NTSB ERA17FA112](https://openairdocs.org/ntsb/ERA17FA112.md): Piper PA38 · East Haven, CT · Accident · 1 fatal · Field investigation · Final report · Feb 22, 2017 · N2452C · Destroyed
  > The failure of the fuel selector valve in a position that restricted fuel flow to the engine, resulting in a total loss of engine power during initial climb due to fuel starvation. Also causal was the operator's failure to effectively detect and resolve the…
- [NTSB GAA16CA514](https://openairdocs.org/ntsb/GAA16CA514.md): Cessna 205 · Ellington, CT · Accident · No injuries · Data collection · Final report · Sep 26, 2016 · N8433Z · Substantial damage
  > The pilot's exceedance of the airplane's critical angle-of-attack during the initial climb after an attempted go-around, which resulted in an aerodynamic stall.
- [NTSB ERA15LA365](https://openairdocs.org/ntsb/ERA15LA365.md): Clark 1000 · Warehouse Point, CT · Accident · Minor injuries · Limited investigation · Final report · Sep 19, 2015 · N9018R · Substantial damage
  > The pilot’s failure to maintain adequate airspeed during the initial climb after takeoff, which resulted in the airplane exceeding its critical angle of attack and experiencing an aerodynamic stall. Contributing to the accident was the pilot's decision to…
- [NTSB ERA13FA358](https://openairdocs.org/ntsb/ERA13FA358.md): Rockwell International 690B · East Haven, CT · Accident · 4 fatal · Field investigation · Final report · Aug 9, 2013 · N13622 · Destroyed
  > The pilot's failure to maintain airspeed while banking aggressively in and out of clouds for landing in gusty tailwind conditions, which resulted in an aerodynamic stall and uncontrolled descent.
- [NTSB ERA09LA531](https://openairdocs.org/ntsb/ERA09LA531.md): Daniel L Patrick Kolb Mark · Mystic, CT · Accident · Minor injuries · Limited investigation · Final report · Sep 20, 2009 · N208NS · Substantial damage
  > The pilot's failure to maintain airspeed during final approach, resulting in an inadvertent stall. Contributing to the accident was the pilot's lack of total flight experience.
