Probable cause

The failure of the propeller control system for undetermined reasons during a precautionary landing after encountering deteriorating weather conditions during a VFR ferry flight. Contributing factor(s) was: the adverse weather conditions, inadequate preflight, a failure of the electrical system for unknown reasons, and the pilot's intentional ground loop.
