## Latest cases

- [NTSB WPR14LA367](https://openairdocs.org/ntsb/WPR14LA367.md): Piper PA 25-235 · Warner Springs, CA · Accident · Serious injuries · Limited investigation · Final report · Sep 6, 2014 · N7117Z · Substantial damage
  > The glider pilot's failure to maintain directional control during the initial climb while being towed, which led to the tow plane's unstable flight and its subsequent aerodynamic stall. Contributing to the accident was the tow pilot's delayed release of the…

  > The pilot's decision to operate the banner-tow flight below the minimum safe altitude specified by federal regulation, which likely limited his ability to recover from a potential loss of airspeed due to a gusting wind condition. Also causal was the pilot’s…
- [NTSB ERA12FA130](https://openairdocs.org/ntsb/ERA12FA130.md): Piper PA-25-235 · Jacksonville, FL · Accident · 1 fatal · Field investigation · Final report · Dec 31, 2011 · N7408Z · Substantial damage

  > The pilot's improper turn while maneuvering during an agricultural application flight, which resulted in an inadvertent aerodynamic stall at low altitude.
- [NTSB ERA09LA131](https://openairdocs.org/ntsb/ERA09LA131.md): Piper PA-25-235 · Pensacola, FL · Accident · 1 fatal · Limited investigation · Final report · Jan 6, 2009 · N7160Z · Substantial damage
  > The pilot’s failure to maintain airspeed following a total loss of engine power during a low-level approach, which resulted in an aerodynamic stall. Contributing to the accident was fuel exhaustion due to the pilot’s inadequate preflight planning.
