The NTSB's narrative final · quoted from the NTSB record

THE PILOT WAS ON A POWER LINE PATROL MISSION WITH AN OBSERVER ON BOARD. ACCORDING TO HIM, THE WIND WAS FROM THE WEST AT ABOUT 20 KTS AND HE WAS FLYING EAST ALONG A LINE THAT MADE A 90 DEGREE TURN TO THE NORTH. AT THAT POINT, HE BEGAN A 270 DEGREE TURN TO THE RIGHT TO FOLLOW THE LINE NORTH. HOWEVER, ABOUT HALF WAY THROUGH THE TURN, HE SAW THAT IF HE CONTINUED, THE TURN WOULD TAKE HIM OVER A FARMYARD AND CATTLE. HE REVERSED THE TURN BACK TO THE LEFT, TOWARD THE EAST. AS HE ROLLED OUT OF THE LEFT TURN GOING DOWNWARD, THE AIRCRAFT STALLED. HE ATTEMPTED TO RECOVER, BUT THERE WAS INSUFFICIENT ALTITUDE AND THE PLANE CRASHED.
