What happened
The pilot reported that during the course of the flight, the aircraft inadvertently drifted north of the intended flight path. This deviation led the aircraft into an area characterized by higher terrain elevation.
While navigating this region, the aircraft encountered whiteout conditions, which severely restricted visibility. In response to these hazardous weather conditions, the pilot made the decision to turn to the right. The objective of this maneuver was to seek out areas with better visibilities rather than descending toward lower terrain.
Despite these efforts, the aircraft struck a snow-covered slope while maintaining level flight.
