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 FTW96LA350](https://openairdocs.org/ntsb/FTW96LA350.md): Hardy Quickie Q-200 · Hudson, CO · Accident · Minor injuries · Limited investigation · Final report · Aug 18, 1996 · N6NH · Substantial damage
  > delamination of a propeller blade. A factor relating to the accident was: the terrain condition in the emergency landing area (soft/sandy berm and ditch).
- [NTSB CHI96FA278](https://openairdocs.org/ntsb/CHI96FA278.md): Lancair 320 · Fond Du Lac, WI · Accident · 1 fatal · Field investigation · Final report · Aug 8, 1996 · N320L · Destroyed
  > the fatigue in the propeller flange with soft material and oversized lightening holes. A factor was the pilot's inability to maintain control of the aircraft due to the exceeded weight and balance which led to a stall/spin.
- [NTSB FTW96LA318](https://openairdocs.org/ntsb/FTW96LA318.md): Steward Breezy · Owasso, OK · Accident · Minor injuries · Limited investigation · Final report · Jul 25, 1996 · N2343 · Substantial damage
  > the pilot's failure to secure his cargo prior to departure. A factor was the lack of suitable terrain available for the forced landing.
- [NTSB ANC96LA096](https://openairdocs.org/ntsb/ANC96LA096.md): Beech 18 · Fairbanks, AK · Accident · No injuries · Limited investigation · Final report · Jul 6, 1996 · N700WA · Substantial damage
  > The malfunction of the propeller control unit on the right engine.
