Recent Air Tractor Inc AT-401 accidents
The pilot's failure to maintain clearance from the power lines during low altitude maneuvering.
The pilot’s failure to maintain proper airspeed after liftoff, which resulted in the airplane exceeding its critical angle of attack and an aerodynamic stall.
A loss of engine power for a reason that could not be determined based on available information.
The wear-related failure of the airframe fuel boost pump, which resulted in fuel starvation and a loss of engine power.
The pilot’s inadequate preflight planning, which resulted in his attempt to take off for the agricultural application flight with the airplane over its maximum gross weight in high-density altitude conditions and led to the airplane’s degraded climb performance and subsequent impact with terrain.
The loss of power due to the failure of the No. 2 exhaust valve and rocker boss during takeoff.
A loss of the No. 1 cylinder’s compression due to a stuck exhaust valve caused by a lack of sufficient valve clearance, which resulted in a loss of engine power and a forced landing. Contributing to the loss of engine power were the worn intake and exhaust valves in cylinders No. 3 and 4.
The mechanical failure of the engine power section, which resulted in a loss of engine power.
