## Latest cases

- [NTSB ERA22FA315](https://openairdocs.org/ntsb/ERA22FA315.md): Piper PA12 · Middle Township, NJ · Accident · 1 fatal · Class 3 · Field · Final report · Jul 16, 2022 · N3703M · Substantial damage
  > The pilot’s exceedance of the airplane’s critical angle of attack during a missed banner pickup, which resulted in an aerodynamic stall/spin and loss of control at an altitude too low to recover.
- [NTSB ERA22FA243](https://openairdocs.org/ntsb/ERA22FA243.md): Piper PA-12 · North Myrtle Beach, SC · Accident · 1 fatal · Class 3 · Field · Final report · May 28, 2022 · N4421M · Substantial damage
  > The pilot's exceedance of the airplane's critical angle of attack, which resulted in a subsequent aerodynamic stall at an altitude that was too low for recovery.
- [NTSB GAA19CA551](https://openairdocs.org/ntsb/GAA19CA551.md): Piper PA 12 · Healy, AK · Accident · No injuries · Data collection · Final report · Sep 15, 2019 · N4315M · Substantial damage
  > The pilot's exceedance of the airplane's critical angle of attack while taking off from water in shifting wind conditions.
- [NTSB CEN18LA039](https://openairdocs.org/ntsb/CEN18LA039.md): Piper PA 12 · Dickinson, ND · Accident · Serious injuries · Limited investigation · Final report · Nov 22, 2017 · N4040M · Substantial damage
  > The pilot’s failure to attain adequate airspeed during the short field takeoff, which resulted in an exceedance of the airplane’s critical angle of attack and an aerodynamic stall.
- [NTSB ERA17FA148](https://openairdocs.org/ntsb/ERA17FA148.md): Piper PA 12 · Sanford, FL · Accident · 1 fatal · Field investigation · Final report · Apr 8, 2017 · N3280M · Destroyed
  > The incorrect rigging of the elevator control cables, which resulted in a reversal of elevator control inputs applied by the pilot during the takeoff, an excessive nose-high pitch, and subsequent aerodynamic stall after takeoff. Also causal was the inadequate…
- [NTSB ANC11FA065](https://openairdocs.org/ntsb/ANC11FA065.md): Piper PA-12 · Delta, AK · Accident · 1 fatal · Field investigation · Final report · Jul 17, 2011 · N92770 · Substantial damage
  > The pilot's decision to make a low-altitude turn back to the airport following a loss of engine power, which resulted in an aerodynamic stall and loss of control. Contributing to the severity of the pilot's injuries was the separation of the pilot's seat…
