NTSB narrative
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.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
- API snapshot SHA-256: 6e72f999d26d3755802adc64ebf17cb7efc428f23f300fdb644fcdc7cec72686; retrieved 2026-09-21T18:05:19.969Z.
