Aviation accident MIA03FA071

The pilot's inadequate in-flight planning/decision by his continued VFR flight into instrument meteorological condition after receiving an in-flight weather advisory. Also causal was his failure to maintain aircraft control, which resulted in flight that exceeded the design limits of the aircraft and resulted in an in-flight breakup. Contributing factors were the pilot's overconfidence in his personal ability, and the failure of the National Weather Service to issue an Airmet to identify IFR conditions for the area of the accident.
