A private pilot without instrument rating flew into instrument meteorological conditions during a pleasure flight, lost visual reference, and the aircraft collided with wooded terrain after disappearing from radar.

Incident Overview

A non-instrument rated private pilot was conducting a pleasure flight when he inadvertently entered instrument meteorological conditions (IMC). The pilot subsequently lost the ability to maintain visual flight rules (VFR) and collided with wooded terrain.

Communication with Flight Service

While en route, the pilot contacted the Bangor Automated Flight Service Station (AFSS) and reported difficulty maintaining VFR flight. The AFSS was unable to establish a direction-finding (DF) steer on the airplane and advised the pilot to contact Boston Center.

Air Traffic Control Involvement

Boston Center established radar contact with the aircraft. Controllers issued vectors and minimum safe altitudes for a route to Houlton. While proceeding toward Houlton, the pilot reported that he was disoriented. Shortly after this transmission, the airplane disappeared from radar.

Post-Accident Examination
