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 WPR24FA124](https://openairdocs.org/ntsb/WPR24FA124.md): Gulfstream 695A · San Bernardino, CA · Accident · 1 fatal · Class 3 · Field · Final report · Apr 14, 2024 · N965BC · Destroyed
  > The pilot’s continued use of the airplane’s autopilot after flight into moderate to severe icing conditions, which resulted in an exceedance of the airplane’s critical angle of attack and an aerodynamic stall.
- [NTSB WPR23FA080](https://openairdocs.org/ntsb/WPR23FA080.md): Embraer Executive EMB-505 · Provo, UT · Accident · 1 fatal · Class 3 · Field · Final report · Jan 2, 2023 · N555NR · Substantial damage
  > The pilot’s failure to deice the airplane before takeoff in weather conditions conducive to ice accumulation, which resulted in an ice-contaminated wing and subsequent stall during takeoff.
- [NTSB CEN21LA030](https://openairdocs.org/ntsb/CEN21LA030.md): Cessna 210 · Lubbock, TX · Accident · 1 fatal · Class 3 · Limited · Final report · Oct 26, 2020 · N9622T · Destroyed
  > The pilot’s improper decision to fly into icing conditions with an airplane that was not equipped for icing, which led to structural icing and a subsequent loss of airplane control, and the pilot’s impairment from carbon monoxide poisoning due to a cracked…
- [NTSB CEN16LA098](https://openairdocs.org/ntsb/CEN16LA098.md): Cessna 441 · Fargo, ND · Accident · No injuries · Limited investigation · Final report · Jan 8, 2016 · N779CC · Substantial damage
  > The pilot’s failure to cycle the surface deice boots during the instrument approach in icing conditions, which led to ice accumulation on the leading edges of the wings and empennage, and resulted in an aerodynamic stall and subsequent hard landing.
- [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 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…
