Probable cause

The noninstrument-rated pilot's decision to continue visual flight into an area of instrument meteorological conditions (IMC), which resulted in a loss of control due to spatial disorientation.

NTSB narrative

The non-instrument-rated private pilot received a weather briefing before departing on the visual flight rules (VFR) cross-country flight, which included the presence of moderate to heavy precipitation, including some thunderstorms, near the destination airport. The pilot was advised that VFR flight was not recommended and that he should seek additional weather information as he neared his destination. Weather observations and satellite imagery indicated that instrument meteorological conditions (IMC) prevailed in the vicinity of where the pilot began making multiple course changes and at the accident site. It is likely that the pilot encountered rain, possibly heavy rain, during the final portion of the flight. Weather observations near the destination airports, AIRMETs, and visible satellite weather images all indicated that the pilot encountered IMC en route. Examinations of the airframe and engine did not reveal any anomalies consistent with a preimpact failure or malfunction. The restricted visibility conditions present in the area were conducive to the development of spatial disorientation, and the airplane's maneuvering and spiraling descent are consistent with the known effects of spatial disorientation. It is likely that the pilot experienced spatial disorientation during an encounter with instrument meteorological conditions, which resulted in a loss of control.

Analysis

Primary failure mode
