## Narrative

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

IN AN EMAIL FROM THE PILOT, HE STATED "I HAVE FLOWN UNDER THAT SET OF WIRES PROBABLY HUNDREDS OF TIMES SINCE I CONSIDERED IT SAFER THAN TRYING TO GO OVER IT WITH A LOADED AIRCRAFT.  THAT MORNING I HAD 13 LOADS 5.5 MILES FROM AIRPORT,( 5MILES FROM WIRE).  I WAS ON MY EIGHTH LOAD THAT SUNDAY MORNING AND EVERYTHING WAS VERY ROUTINE." PILOT ALSO MENTIONED THAT HE WAS UPSET ABOUT AN ARGUMENT HE HAD WITH ^PRIVACY DATA OMITTED^, HE WENT ON TO SAY "BASICALLY I WAS IN SUCH THOUGHT THAT I COMPLETELY DON’T REMEMBER FLYING AFTER TAKEOFF. AFTER THE ACCIDENT I HAD NO IDEA THAT I HAD HIT THE WIRE, I THOUGHT MAYBE A MID AIR OR SOMETHING, ONLY AFTER GETTING OUT OF WRECKAGE AND LOOKING BACK DID I REALIZE I HAD HIT THE WIRE." PILOT ALSO MENTIONED THAT FATIGUE MIGHT HAVE BEEN A FACTOR. PICTURES FROM THE WRECKAGE REVEALED THE UPPER WINGTIP WAS STILL HANGING FROM THE WIRE. THE AIRCRAFT CAME TO REST IN A RICE FIELD NEAR THE POWERLINE. SIGNATURES FROM THE PROPELLER AFTER IMPACT INDICATE THAT THE ENGINE WAS OPERATING NORMALLY.

## 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.

Probable cause: The pilot’s failure to maintain clearance from a power line during a low-level aerial application flight. Contributing to the accident was the pilot’s fatigue.
