Aircraft Accident/Incident Report

Tremonton, Utah 84337
Saturday, January 3, 1998 19:13 MST

NTSB Narrative Summary Released at Completion of Accident

The noninstrument-rated private pilot, a foreign national, embarked on a solo cross-country flight to fulfill the experience requirements required for commercial pilot certification. FSS advised the pilot that VFR flight was not recommended. The pilot filed a VFR flight plan and departed Ogden, Utah. He arrived in Caldwell, Idaho, refueled, and obtained another FSS weather briefing. Again, he was advised that VFR flight was not recommended. He filed a VFR flight plan and departed Caldwell en route back to Ogden. Radar data indicated that the pilot did not track the airway to Malad City, Idaho, but instead followed a highway to the vicinity of Tremonton, Utah. There, it was seen to maneuver in a 'primary weather cell.' The wreckage was located 3 days later within 0.1 mile of the last radar contact.

NTSB Probable Cause Narrative

The pilot's continued VFR flight into instrument meteorological conditions, becoming spatially disoriented and his subsequent loss of aircraft control. Factors were the dark night and weather conditions that included obscuration and snow.
