NTSB narrative
During takeoff from a private airstrip, the aerial application airplane skimmed the top of a cotton field. When the pilot took off with a 'heavy load of fertilizer.' The airplane departed to the north on a half paved, half turf runway measuring approximately 3,000 feet long. An examination was conducted of the accident site revealing that a thin-walled plastic pipe carrying water for crops had been hit by the airplane. There was evidence that the airplane continued to 'skim the top of a cotton field for 2,000 feet.' The airplane came to rest inverted in the cotton field.
Probable cause
The pilot's failure to attain the proper takeoff airspeed.

- 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.
