NTSB narrative
The pilot reported that, during the initial climb, a sudden partial loss of engine power occurred. The pilot lost airplane control as the airplane drifted left and then stalled. The airplane impacted terrain near the runway departure end. A significant fuel spill occurred, but no postimpact fire ensued. A postaccident examination of the airframe and engine revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation.
Postaccident toxicology testing of the pilot's blood and urine specimens, which were obtained about 4 hours after the accident, revealed the presence of amphetamine and methamphetamine at levels consistent with recreational drug use shortly before the accident flight. Given the levels of methamphetamine and amphetamine in his blood 4 hours after the accident, it is likely that the pilot's judgment and ability to respond to an urgent or emergency situation was significantly impaired and contributed to the accident.
Probable cause
The pilot’s loss of airplane control after a partial loss of engine power for reasons that could not be determined because postaccident examination of the airframe and engine revealed no evidence of mechanical malfunctions or failures, which resulted in an aerodynamic stall. Contributing to the accident was the pilot’s impairment as a result of his recent use of illicit drugs.

- 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.
