  > The pilot's decision to attempt to take off in an overweight airplane in high density altitude conditions, which resulted in the airplane’s inability to climb, an aborted takeoff, and a subsequent runway excursion.
- [NTSB GAA18CA534](https://openairdocs.org/ntsb/GAA18CA534.md): Robinson R44 · Girdwood, AK · Accident · No injuries · Data collection · Final report · Aug 30, 2018 · N99645 · Substantial damage

  > The pilot's improper flap setting for takeoff and subsequent exceedance of the airplane’s critical angle of attack, which resulted in an aerodynamic stall. Contributing was the overgross state of the airplane.
- [NTSB ANC18FA055](https://openairdocs.org/ntsb/ANC18FA055.md): De Havilland DHC-2 · Willow, AK · Accident · 1 fatal · Class 2 · Field · Final report · Jul 19, 2018 · N9878R · Destroyed
  > The pilot's exceedance of the airplane's critical angle of attack during departure climb, which resulted in an aerodynamic stall. Contributing to the accident was the pilot's improper decision to load the airplane beyond its allowable gross weight and center…
- [NTSB CEN18WA279](https://openairdocs.org/ntsb/CEN18WA279.md): Cessna 150 · Tortola, British Virgin Islands · Accident · 1 fatal · Foreign investigation · Jul 18, 2018 · N66778 · Substantial damage
