## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

THE PIC APPROACHED THE GRASS RUNWAY, TOUCHED DOWN, AND THE AIRCRAFT PULLED HARD LEFT.  THE PILOT APPLIED FULL RIGHT RUDDER AND FULL RIGHT AILERON BUT WAS UNABLE TO COUNTER THE HARD LEFT PULL. THE AIRCRAFT VEERED LEFT AND ENTERED AN ADJACENT CORN FIELD, WHERE THE NOSE GEAR COLLAPSED AND THE PLANE ROLLED OVER THE NOSE, COMING TO REST INVERTED. A LOCAL AERIAL APPLICATION PILOT ON SCENE TOLD THE PIC HE OBSERVED THE TRACKS IN THE GRASS, WENT TO THE PLANE AND TRIED TO TURN THE LEFT WHEEL, WHICH HE FOUND LOCKED UP.  HE TOLD THE PIC HE HAD TRIED TO TURN THE WHEEL AND THAT HE COULD BARELY MOVE IT.  THE PIC STATED THAT BY THE TIME HE HAD AN OPPORTUNITY TO CHECK IT HIMSELF LATER, THE LEFT MAIN WHEEL TURNED FREELY. A BRAKE INSPECTION BY THE NTSB WAS LATER PERFORMED, FINDING CORROSION AND SURFACE PITTING WITHIN THE BRAKE ASSEMBLY.

## The NTSB's investigation of this event (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
