NTSB narrative
The private pilot was conducting a personal cross-country flight. The pilot's friend reported that he provided weather information to the pilot about 1 hour before the flight; no record was found indicating that the pilot or the friend obtained a formal weather briefing before he departed for the night cross-country flight. A review of weather information revealed that, about 1 hour 20 minutes into the flight, as the airplane was nearing the destination airport, it encountered a strong cold front boundary with associated severe wind shear and turbulence. Review of radar data revealed that, during the following 13 minutes, the flight completed numerous course deviations, including three complete left circuits and two right circuits, before impacting wooded terrain. Review of the last 3 minutes of radar data revealed that the airplane's altitude oscillated between 2,100 and 200 ft mean sea level (msl) as it completed the two right circuits and one of the left circuits before it impacted terrain. The last target was recorded about 2,000 ft southeast of the accident site at an altitude of 525 ft msl. Examination of the wreckage did not reveal any preimpact mechanical malfunctions or failures that would have precluded normal operation. Based on the evidence, it is likely that the airplane encountered wind shear and turbulent conditions upon encountering the strong cold front boundary and that the pilot subsequently lost airplane control.
Probable cause
The pilot's inadequate preflight weather planning and in-flight weather evaluation, which resulted in an encounter with a strong cold front and the pilot's subsequent loss of airplane control.

- 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: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2016-11-20.
