What happened
The pilot reported departing under visual meteorological conditions described as 'ok visibility' and proceeding toward Wrangell, Alaska. While en route, the aircraft encountered ground fog. The pilot was attempting to turn around when the aircraft impacted a hillside and subsequently struck trees. A passenger later reported to police that the aircraft appeared to be descending continuously prior to impact.
Findings
The primary factor contributing to this accident was the pilot's decision to continue flight into deteriorating weather conditions, specifically ground fog, which led to a loss of situational awareness and controlled flight into terrain. The lack of instrument meteorological conditions training or equipment may have contributed to the inability to maintain safe altitude.
Safety message
Pilots are reminded that visual flight rules require adequate visibility and cloud clearance. Continuing flight into known or forecasted fog without proper instrumentation or experience can lead to spatial disorientation and controlled flight into terrain.
