- [NTSB ERA20LA023](https://openairdocs.org/ntsb/ERA20LA023.md): Piper J3C · Grand Bay, AL · Accident · No injuries · Class 3 · Limited · Final report · Oct 27, 2019 · N7009H · Substantial damage
  > A loss of engine power during initial climb due to carburetor ice that formed during an extended ground delay, and the pilot's failure to use carburetor heat before initiating the takeoff.
- [NTSB ERA18FA208](https://openairdocs.org/ntsb/ERA18FA208.md): Champion 8GCBC · Foley, AL · Accident · 2 fatal · Field investigation · Final report · Aug 4, 2018 · N424A · Destroyed
  > The pilot's exceedance of the airplane's critical angle of attack, which resulted in a subsequent aerodynamic stall and spin at an altitude that was too low for recovery.
- [NTSB ERA17LA075](https://openairdocs.org/ntsb/ERA17LA075.md): Cessna 172 · Bridgeport, AL · Accident · Serious injuries · Limited investigation · Final report · Dec 27, 2016 · N3772F · Substantial damage
  > The pilot's decision to make steep turns to the right while operating on the right fuel tank with low fuel quantity, which led to a loss of engine power due to unporting of the right fuel tank and fuel starvation.
- [NTSB GAA15LA296](https://openairdocs.org/ntsb/GAA15LA296.md): Bell 206 · Ozark, AL · Accident · No injuries · Limited investigation · Final report · Sep 24, 2015 · N49660 · Substantial damage
