## Latest cases

- [NTSB WPR26LA083](https://openairdocs.org/ntsb/WPR26LA083.md): Robinson R44 · Parkman, WY · Accident · No injuries · Class 4 · Limited · Final report · Jan 19, 2026 · N996NR · 2 aircraft · Substantial damage
  > The pilots’ failure to maintain separation while conducting air work in a common operational area. Contributing to the accident was the pilots’ divided attention associated with the mission activity and unreliable radio communications.
- [NTSB DCA24FA017](https://openairdocs.org/ntsb/DCA24FA017.md): Textron 510 · Houston, TX · Accident · No injuries · Class 2 · Field · Final report · Oct 24, 2023 · N510HM · 2 aircraft · Substantial damage
  > The takeoff by the flight crew of N269AA, without a takeoff clearance, which resulted in a collision with N510HM that was landing on an intersecting runway. Contributing to the accident was the N269AA crew’s expectation bias and distraction.
- [NTSB ERA20FA096](https://openairdocs.org/ntsb/ERA20FA096.md): Cessna 501 · Fairmount, GA · Accident · 4 fatal · Class 3 · Field · Final report · Feb 8, 2020 · N501RG · Substantial damage
  > The pilots’ loss of control in flight in freezing instrument meteorological conditions due to spatial disorientation and the cumulative effects of task saturation.
- [NTSB CEN19MA141](https://openairdocs.org/ntsb/CEN19MA141.md): De Havilland DHC-2 · Ketchikan, AK · Accident · 6 fatal · Class 1 · Major · Final report · May 13, 2019 · N952DB · 2 aircraft · Destroyed
  > The inherent limitations of the see-and-avoid concept, which prevented the two pilots from seeing the other airplane before the collision, and the absence of visual and aural alerts from both airplanes’ traffic display systems, while operating in a geographic…
- [NTSB CEN18FA144](https://openairdocs.org/ntsb/CEN18FA144.md): Cirrus Design SR22 · Williamsburg, PA · Accident · 2 fatal · Field investigation · Final report · Apr 19, 2018 · N451TD · Destroyed
  > The pilot's failure to obtain an updated weather briefing before the flight and his subsequent loss of airplane control due to spatial disorientation while maneuvering in instrument meteorological conditions during a diversion to an alternate airport after…
- [NTSB WPR17IA086](https://openairdocs.org/ntsb/WPR17IA086.md): Beech A36TC · Livermore, CA · Incident · No injuries · Class 3 · Incident · Final report · Apr 10, 2017 · N755R · Minor damage
