NTSB narrative

The pilot of the Air Tractor airplane reported that after loading the airplane's chemical tanks he began taxiing for departure. The pilot said he was watching his left wing to clear obstacles, but sun glare made looking to the right difficult. The pilot said he did not see an Aero Commander airplane that was stopped on the taxiway, waiting to enter the loading area. The propeller of the Air Tractor struck the right wing of the Aero Commander, substantially damaging its right wing. The pilots of each airplane reported that there were no pre-impact mechanical malfunctions or failures with the airframes and engines of their respective aircraft that would have precluded normal flight.

Probable cause

The pilot of the Air Tractor's failure to maintain clearance from the Aero Commander.

  • 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.
