  > Total loss of engine power for reasons that could not be determined based on the available information.
- [NTSB GAA18CA414](https://openairdocs.org/ntsb/GAA18CA414.md): North American AT · Moneta, VA · Accident · No injuries · Data collection · Final report · Jul 5, 2018 · N29963 · Substantial damage
  > The pilot's failure to maintain a proper descent rate, which resulted in a bounced landing and his subsequent failure to maintain directional.
- [NTSB GAA18CA401](https://openairdocs.org/ntsb/GAA18CA401.md): Grumman G164 · Rochelle, IL · Accident · No injuries · Data collection · Final report · Jul 5, 2018 · N6795Q · Substantial damage
  > The pilot’s failure to move the power lever to the proper position before takeoff, which resulted in insufficient airspeed and a subsequent aerodynamic stall.
- [NTSB GAA18CA410](https://openairdocs.org/ntsb/GAA18CA410.md): Ayres S2R · Pantego, NC · Accident · No injuries · Data collection · Final report · Jul 1, 2018 · N3098L · Substantial damage
  > The pilot's failure to maintain the proper approach path during landing, which resulted in landing short of the runway.
- [NTSB GAA18CA371](https://openairdocs.org/ntsb/GAA18CA371.md): Air Tractor AT 301 · Hutchinson, MN · Accident · No injuries · Data collection · Final report · Jun 20, 2018 · N3169D · Substantial damage
  > The pilot’s improper preflight fuel planning, which resulted in fuel exhaustion and the subsequent total loss of engine power.
- [NTSB WPR18FA155](https://openairdocs.org/ntsb/WPR18FA155.md): North American SNJ 2 · Melville, NY · Accident · 1 fatal · Field investigation · Final report · May 30, 2018 · N62382 · Destroyed
  > The pilot's exceedance of the airplane's critical angle of attack, which resulted in an aerodynamic stall, spin, and subsequent impact with terrain.
