NTSB narrative
The pilot stated that, after takeoff for an aerial application flight, the airplane was "a little sluggish" while he was maneuvering it about 30 feet above the ground. He stated that he was gently pulling back on the control stick when the airplane started to descend. He then advanced the throttle; however, the airplane continued to descend and then impacted terrain and flipped over. Postaccident examination of the engine and airframe did not reveal any anomalies that would have precluded normal operation. The pilot stated that the engine instruments did not indicate any power loss and that he topped off the fuel tanks before the flight. He also reported that the wind at the time of takeoff was about 5 knots with no gusts, and the atmospheric conditions were not conducive to the accumulation of carburetor ice. The airplane was below its maximum takeoff gross weight. The reason for the airplane's failure to climb could not be determined.
Probable cause
The airplane’s failure to climb after takeoff for reasons that could not be determined because postaccident examinations of the engine and airframe did not reveal any anomalies that would have precluded normal operation.

Source notes (4)
- 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.
