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 CEN15LA091](https://openairdocs.org/ntsb/CEN15LA091.md): Cessna 208B · Roswell, NM · Accident · No injuries · Limited investigation · Final report · Dec 30, 2014 · N950FE · Substantial damage
  > The pilot's failure to maintain adequate airspeed to compensate for icing on the airplane's wings and control surfaces during a circling approach, which resulted in an aerodynamic stall and impact with terrain.
- [NTSB DCA15MA029](https://openairdocs.org/ntsb/DCA15MA029.md): Embraer EMB-500 · Gaithersburg, MD · Accident · 6 fatal · Class 1 · Major · Final report · Dec 8, 2014 · N100EQ · Destroyed
  > the pilot's conduct of an approach in structural icing conditions without turning on the airplane's wing and horizontal stabilizer deice system, leading to ice accumulation on those surfaces, and without using the appropriate landing performance speeds for…
- [NTSB CEN15LA021](https://openairdocs.org/ntsb/CEN15LA021.md): Raytheon 58 · Dixon, IL · Accident · No injuries · Limited investigation · Final report · Oct 4, 2014 · N345PG · Substantial damage
  > The pilots’ improper decision to continue flight in icing conditions after the deicing boots could not shed accumulated ice, which resulted in a temporary loss of airplane control.
- [NTSB CEN14IA139](https://openairdocs.org/ntsb/CEN14IA139.md): Cirrus Design SR22 · Gunnison, CO · Incident · No injuries · Incident investigation · Final report · Feb 14, 2014 · N18DN · Minor damage
  > The pilot's improper decision to initiate the flight into an area with forecast icing conditions, which resulted in an encounter with in-flight icing conditions that prevented the airplane from being able to maintain altitude.
- [NTSB DCA14FA058](https://openairdocs.org/ntsb/DCA14FA058.md): Embraer EMB145 - EP · Memphis, TN · Accident · No injuries · Class 3 · Field · Final report · Feb 5, 2014 · N802HK · Substantial damage
  > the failure of the flight crew to adequately monitor the system for proper operation and manually activate the system during the flight in icing conditions. Contributing to the accident was the crew's limited training on the manual operation of the anti-ice…
- [NTSB ERA14FA112](https://openairdocs.org/ntsb/ERA14FA112.md): Gulfstream AM Corp Comm Div 690 · Bellevue, TN · Accident · 4 fatal · Field investigation · Final report · Feb 3, 2014 · N840V · Destroyed
  > The pilot's failure to maintain airspeed with one engine inoperative, which resulted in a loss of control while on approach. Contributing to the accident were airframe ice accumulation due to conditions conducive to icing and the loss of engine power on one…
