## Narrative

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

PILOT WAS PERFORMING AGRICULTURE OPERATIONS WHEN HE REPORTED THE ENGINE SUDDENLY VIBRATED AND THEN STOPPED.  THE PILOT WAS APPROACHING TWO SETS OF HIGH POWER TENSION LINES, AND HAD TO FLY UNDERNEATH THE POWER LINES.  AFTER CLEARING THE POWER LINES, HE WAS ABLE TO LAND THE AIRCRAFT IN ANOTHER FIELD.  DURING LANDING, THE AIRCRAFTS LANDING GEAR WAS CAUGHT IN THE GROUND AND THE AIRCRAFT CARTWHEELED ON TOP OF ITSELF, POSITIONING THE AIRCRAFT TAIL UP.

THERE IS SUBSTANTIAL DAMAGE TO THE WING SPARS, PROPELLER, AND LANDING GEAR.

THE PILOT WAS ABLE TO REMOVE HIMSELF FROM THE AIRCRAFT AND DID NOT ACQUIRE ANY INJURIES.  THE PILOT PROMPTLY RETURNED BACK TO THE AIRCRAFT AND TURNED OFF THE MASTER POWER SWITCH.

PILOT STATEMENT HAS BEEN ADDED TO THE OFFICE WORKING FILE.

AUGUST 9TH, AND AUGUST 10TH, 2021, ASI INSPECTOR ^PRIVACY DATA OMITTED^ ASSISTED ^PRIVACY DATA OMITTED^ PRODUCT INTEGRITY/ AIR SAFETY INVESTIGATOR WITH AN AIRCRAFT AND ENGINE EXAMINATION.  DURING THE INVESTIGATION IT APPEARED THAT THE TURBINE ENGINE FUEL SOLENOID HAD BEEN ELECTRICALLY CLOSED.  IT WAS DECIDED TO REMOVE THE ELECTRICAL SYSTEM RELATIVE TO THE FUEL SOLENOID SWITCH.  ELECTRICAL SYSTEM WAS REMOVED, AND SENT TO NTSB FOR FURTHER TESTING.

ALSO, ENGINE WAS REMOVED FOR FURTHER INSPECTION BY ^PRIVACY DATA OMITTED^ INVESTIGATOR, AND SENT BACK TO ^PRIVACY DATA OMITTED^ FOR MORE INVESTIGATION.

ALL PERTINENT INFORMATION HAS BEEN SHARED WITH NTSB IIC.

I AM CONSIDERING THIS REPORT CLOSED.  REPORT MAY BE RE-OPENED AND AMENDED IF MORE INFORMATION BECOMES AVAILABLE.
