Reported aircraft: Air Tractor AT-802A
Probable cause: A total loss of engine power due to the fracture of a single 1st stage compressor rotor airfoil in high-cycle fatigue as a result of the erosion and thinning of the airfoil's leading edge. Contributing to the fractured airfoil and loss of engine power was the operator s decision to operate the engine past the manufacturer s recommended time between overhaul.
