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 WPR22FA345](https://openairdocs.org/ntsb/WPR22FA345.md): Piper PA46 · Seligman, AZ · Accident · 2 fatal · Class 3 · Field · Final report · Sep 13, 2022 · N43605 · Substantial damage
  > The student pilot’s continued visual flight into instrument meteorological conditions, which resulted in spatial disorientation, a loss of control, exceedance of the airplane’s design limitations, and in-flight breakup.
- [NTSB WPR22FA100](https://openairdocs.org/ntsb/WPR22FA100.md): Moynihan Richard D Vans RV-7A · White Hills, AZ · Accident · 1 fatal · Class 3 · Field · Final report · Feb 19, 2022 · N787NV · Destroyed
  > The pilot’s improper aerobatic maneuver leading to an airspeed that exceeded the airplane’s design limits, which resulted in rudder flutter and an in-flight breakup.
- [NTSB WPR21FA266](https://openairdocs.org/ntsb/WPR21FA266.md): Beech C90 · Wikieup, AZ · Accident · 2 fatal · Class 3 · Field · Final report · Jul 10, 2021 · N3688P · Destroyed
  > The failure and separation of the left wing’s outboard section due to a fatigue crack in the lower spar cap. Contributing to the accident was the operator’s decision to repair the wing spar instead of replacing it as recommended by the aircraft manufacturer.…
- [NTSB GAA18LA062](https://openairdocs.org/ntsb/GAA18LA062.md): Diamond Aircraft Ind DA 40 · Mesa, AZ · Accident · No injuries · Limited investigation · Final report · Oct 13, 2017 · N965DS · Substantial damage
  > A coyote strike and the subsequent operation of the airplane, which led to internal composite wing structure damage.
- [NTSB DCA16CA197](https://openairdocs.org/ntsb/DCA16CA197.md): Facebook UK Aquila · Yuma, AZ · Accident · No injuries · Data collection · Final report · Jun 28, 2016 · N565AQ · Substantial damage
  > a structural failure of the wing as a result of exceeding the airspeed envelope due to wind gusts which were beyond the capabilities of the autopilot. Contributing to the accident was an insufficient amount of drag to track the glideslope in the presence of…
- [NTSB DCA11MA039](https://openairdocs.org/ntsb/DCA11MA039.md): Boeing 737 · Yuma, AZ · Accident · Minor injuries · Major investigation · Final report · Apr 1, 2011 · N632SW · Substantial damage
  > the improper installation of the fuselage crown skin panel at the S-4L lap joint during the manufacturing process, which resulted in multiple site damage fatigue cracking and eventual failure of the lower skin panel. Contributing to the injuries was flight…
- [NTSB ENG08IA051](https://openairdocs.org/ntsb/ENG08IA051.md): Boeing 737 · Phoenix (PHX), AZ · Incident · No injuries · Incident investigation · Final report · Jun 27, 2008 · N514AU · Minor damage
  > The failure of the MLG was due to cracking in the cylinder wall resulting from a fatigue mechanism which initiated at, and near the inner diameter (ID) surface, with propagation through the wall toward the outer diameter(OD) surface. Crack initiation was due…
