NTSB narrative
The 8,600-hour commercial pilot was maneuvering at a low altitude during a local aerial application flight, when the airplane impacted a tree and subsequently the ground. The airplane came to rest in the upright position and was destroyed by a post-impact fire. All major components of the airplane were accounted for at the accident site. Continuity was established to all of the airplane's flight controls. An examination of the airplane's engine and propeller revealed no pre-impact anomalies. A toxicological evaluation of the pilot's specimens revealed hydrocodone and alprazolam. Both drugs have been shown to have a negative effect on psychomotor task. The level of hydrocodone reported in the pilot's blood was more then 50 times the level expected about one and a half hours following a typical single maximum dose of medication. The level of alprazolam reported in the pilot's blood was consistent with more than twice the dose shown to cause impairment.
Probable cause
The pilot's failure to maintain clearance from trees. Contributing factors were the drug impairment and low maneuvering altitude.

- 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.
