Flight rulesThe regulations the flight operated under: in the US, Part 91 (general aviation), Part 121 (airlines), Part 135 (air taxi and commuter) and others; for flights abroad, the NTSB's coarser commercial or non-commercial code. Glossary

Phase of flightThe stage of the flight when things started to go wrong: standing, taxi, takeoff, initial climb, en route, maneuvering, approach or landing. Glossary
Initial climb
First occurrenceThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary

NTSB narrative

According to the pilot, he stated that he "didn't plan well" for the flight. He attempted to takeoff on about a 180-degree heading from a 3,000-foot-long dirt strip on a hot day with 500 gallons of chemicals on board, full fuel tanks, and a crosswind. He applied full power, started the take-off roll, and the airplane became airborne. But, when the airplane got to the end of the runway, it "wouldn't fly." The pilot tried to dump the chemical load, but was unsuccessful. Subsequently, the landing gear contacted tree tops, and the airplane rolled and collided with the ground. Once the airplane came to a stop, it caught on fire. Weather conditions at an airport located 20 nautical miles northwest of the accident were wind from 250 degrees at 12 knots gusting to 16 knots, clear skies, temperature 84 degrees Fahrenheit, and dew point 37 degrees Fahrenheit. The density altitude was 4,179 feet.

Probable cause

The pilot's improper preflight performance planning, and his failure to establish a climb. Factors were the high density altitude and crosswind.

  • 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, coordinates. 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.
