A low-time, non-instrument rated pilot received a weather briefing with low ceilings and mountain obscuration. Filing VFR, he lost visual reference, attempted to descend through a cloud hole, and the aircraft broke up in flight.

Background

Prior to departure, the pilot obtained a weather briefing for his intended route. The briefer reported low ceilings and mountain obscuration along the route and suggested an alternative away from the mountains and adverse weather. The pilot filed a visual flight rules (VFR) flight plan for his original route.

Flight Sequence

Approaching his destination, the pilot contacted air traffic control (ATC) and stated that he needed assistance locating an airport clear of weather, as he was above an overcast layer and could not see the ground. The controller informed the pilot of multiple cloud layers in the area and instructed him to remain in visual meteorological conditions. With help from other pilots reporting actual weather, the controller guided the aircraft toward an area where the pilot might descend below the overcast.

Final Moments

While en route, the pilot advised the controller that he saw a hole in the clouds and was going to attempt a descent through it. Shortly after this transmission, the aircraft disappeared from radar and no further communications were received from the pilot.

Accident Evidence

Examination of the accident site revealed that the aircraft broke up in flight. The pilot had recently purchased the airplane, was low-time, and lacked an instrument rating. He had not received the required sign-off for solo operation of a complex aircraft.

Probable Cause

The investigation did not specify a probable cause.
