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 WPR23LA136](https://openairdocs.org/ntsb/WPR23LA136.md): Cessna 177RG · Spanish Fork, UT · Accident · No injuries · Class 3 · Limited · Final report · Mar 15, 2023 · N2572V · Substantial damage
  > The retraction of the main landing gear for undetermined reasons.
- [NTSB WPR21LA323](https://openairdocs.org/ntsb/WPR21LA323.md): Cessna 177RG · Albuquerque, NM · Accident · No injuries · Class 3 · Limited · Final report · Aug 15, 2021 · N8029G · Substantial damage
  > The failure of the nose gear hydraulic flex line, which resulted in a loss of hydraulic fluid which prevented the main landing gear from fully extending and locking into place during landing.
- [NTSB WPR20CA188](https://openairdocs.org/ntsb/WPR20CA188.md): Cessna 177RG · Lynden, WA · Accident · Serious injuries · Class 4 · Data collection · Final report · Jun 14, 2020 · N1958Q · Substantial damage
  > The pilot's failure to maintain control of the airplane during the landing approach, which resulted in the airplane exceeding its critical angle of attack, an aerodynamic stall, hard landing, and a landing gear collapse.
- [NTSB GAA16CA074](https://openairdocs.org/ntsb/GAA16CA074.md): Cessna 177 · Palm Springs, CA · Accident · No injuries · Data collection · Final report · Nov 14, 2015 · N2112Q · Substantial damage
  > The failure of a shaft seal at the nose gear retraction/extension actuator, which resulted in a loss of hydraulic fluid and a main landing gear collapse during landing.
- [NTSB WPR12LA383](https://openairdocs.org/ntsb/WPR12LA383.md): Cessna 177RG · Olympia, WA · Accident · No injuries · Limited investigation · Final report · Aug 31, 2012 · N300ZX · Substantial damage
