NTSB narrative
AS THE PILOT WAS MAKING A SWATH RUN NEAR A MAJOR POWER LINE, THE ACFT'S RIGHT WING HIT A GUY WIRE THAT WAS ANCHORED ABOUT 95 FT TO THE SIDE OF THE POWER LINE. THE GUY WIRE SEVERED THE RIGHT WING & THE ACFT CRASHED. THE PLT RPRTD THAT IF THE UNMARKED GUY WIRE HAD BEEN MORE VISIBLE, THE ACDNT WOULD NOT HAVE OCCURRED.
Probable cause
INADEQUATE VISUAL LOOKOUT BY THE PILOT (FAILED TO SEE & AVOID) WHICH RESULTED IN HIS FAILURE TO MAINTAIN CLEARANCE FROM THE OBSTRUCTION. CONTRIBUTING FACTORS WERE: THE UNMARKED GUY WIRE & THE PILOT'S LACK OF VISUAL CUES (VISUAL PERCEPTION).

- 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: 9adfe80f12da12b5cce20b88f48a6a8a3d5efa9d727712efa5fba2c8a8760e68; retrieved 2026-09-22T00:07:24.351Z.
