  > The pilot's lapse in monitoring the airplane's speed during a low level aerial application maneuver and its subsequent stall during the maneuver.
- [NTSB CEN14CA314](https://openairdocs.org/ntsb/CEN14CA314.md): Air Tractor AT 402B · Newport, AR · Accident · Minor injuries · Data collection · Final report · Jun 21, 2014 · N428JJ · Substantial damage
  > The pilot misjudged his altitude which resulted in the airplane contacting a wire during the low altitude aerial application maneuver.
- [NTSB ERA12CA517](https://openairdocs.org/ntsb/ERA12CA517.md): Air Tractor AT-402B · Gum Neck, NC · Accident · No injuries · Data collection · Final report · Aug 17, 2012 · N5127T · Substantial damage
  > The pilot's failure to maintain airplane control during the takeoff roll. Contributing to the accident was the rough condition of the runway.
- [NTSB CEN12LA453](https://openairdocs.org/ntsb/CEN12LA453.md): Air Tractor AT-402B · Britt, IA · Accident · 1 fatal · Limited investigation · Final report · Jul 17, 2012 · N4843J · Substantial damage
  > The pilot’s failure to maintain clearance from power transmission lines during an agricultural application operation. Contributing to the accident was the pilot’s distracted attention due to personal cell phone use during flight operations.
- [NTSB ERA10LA450](https://openairdocs.org/ntsb/ERA10LA450.md): Air Tractor AT402 · Pompano Beach, FL · Accident · No injuries · Limited investigation · Final report · Aug 28, 2010 · N4172U · Substantial damage
  > The pilot's delayed decision to abort the takeoff, which resulted in a runway overrun and a subsequent collision with obstacles and terrain. Contributing to the accident was the airplane's high gross weight.
- [NTSB CEN10CA343](https://openairdocs.org/ntsb/CEN10CA343.md): Air Tractor AT-402B · Virden, IL · Accident · No injuries · Data collection · Final report · Jun 19, 2010 · N5120E · Substantial damage
  > The pilot's decision to take off from a wet grass runway at an airplane weight and density altitude that precluded a normal takeoff and climb.
- [NTSB ERA10CA309](https://openairdocs.org/ntsb/ERA10CA309.md): Air Tractor AT-402B · Alcolu, SC · Accident · No injuries · Data collection · Final report · Jun 10, 2010 · N5085Q · Substantial damage
  > The pilot’s failure to maintain clearance from a tree. Contributing to the accident was the sunglare.
