## Narrative

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

SHORTLY AFTER TAKE OFF, THE ENGINE STARTED TO SURGE.  IT WOULD LOSE POWER, THEN GAIN POWER. THE SITUATION PROGRESSIVELY BECAME WORSE.  THE PILOT DID NOT KNOW IF HE HAD THE POWER TO TURN AROUND AND LAND AT THE AIRPORT SAFELY, SO HE LANDED IN A FIELD CLOSE TO HIM.  THE PILOT LANDED SAFELY BUT THE TALL GRASSY FIELD CAUSED THE AIRCRAFT TO NOSE OVER AND FLIP ONTO ITS BACK AT SLOW SPEED CAUSING SUBSTANTIAL DAMAGE TO TAIL. THE CAUSE OF THE POWER LOSS IS UNKNOWN.  THE NTSB STATED THEY WOULD HAVE SOMEONE LOOK AT THE ENGINE TO TRY AND DETERMINE THE CAUSE FOR POWER LOSS.
