Probable cause

The non instrument-rated pilot-in-command's decision to continue flight into known instrument meteorological conditions (thunderstorm) and failure to maintain airspeed (vso) while maneuvering. Contributing to the accident was the pilot-in-command's failure to obtain a weather briefing and to ensure that required VFR day flight instruments were installed.

Analysis

The non instrument-rated pilot departed on a VFR cross-country flight without obtaining a weather briefing. The airplane was not equipped with the required VFR day flight equipment. The pilot encountered a thunderstorm. While maneuvering the airplane, the pilot experienced an in-flight loss of control for failure to maintain airspeed (vso). This resulted in stall/spin, and collision with terrain.
