NTSB narrative
The pilot of the airplane was holding short of the runway for takeoff when he asked the pilot of an inbound helicopter to side-step to the taxiway so that the airplane could depart. The helicopter pilot reported that a side-step would have resulted in the helicopter flying directly over the airplane and that he side-stepped the helicopter toward the taxiway after clearing the airplane. An airport surveillance camera captured the airplane start the takeoff roll after the helicopter passed. Shortly after takeoff, the airplane entered a steep roll and impacted the runway. A postimpact fire ensued. Toxicology testing of the pilot was positive for ethanol in blood, vitreous fluid, urine, gastric contents, and liver tissue. The ethanol in blood concentration (0.108 gm/dL) was associated with impairment, and alcohol consumption was fairly recent to the accident based on the concentration levels in the pilot’s body. The pilot completed building the airplane about 5 months before the accident. The engine had a history of high oil and cylinder head temperatures, which may have been a factor in the pilot’s decision to depart so soon after the helicopter to reduce idling time on the ground. Based on the available information, it is likely that the airplane encountered wake turbulence from the landing helicopter during takeoff, which resulted in the pilot’s loss of control. It is likely that the pilot’s impairment from ethanol contributed to the accident.
Probable cause
The pilot’s decision to depart shortly after a landing helicopter, which resulted in an encounter with the helicopter’s wake turbulence and a loss of airplane control. Contributing to the accident was the pilot’s impairment by his recent use of ethanol.

Source notes (5)
- 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.
- API snapshot SHA-256: d6c1db1e83faf91d7960bc2b77c20098608bb7ec03f4253dff4692682b5f4333; retrieved 2026-09-15T07:34:24.388Z.
- Corrected after a review of the NTSB narrative, which states these values explicitly: departure. The airplane departed and crashed at Wadsworth Municipal Airport (3G3), Wadsworth, OH; the destination label and accident location spell it Wadsworth, so "Wadworth" is a misspelling.
