At approximately 1330 local time, N444AM crashed and burned southeast of Kelso, CA fatally injuring all 5 souls onboard. The airplane was destroyed and fire damage to the passenger compartment and cockpit prevented toxicology testing. Onsite investigation revealed that N444AM sustained an inflight breakup of the empennage portion of the flight. Radar reports, prior to the crash, showed unusual altitude and heading changes which may have caused the aircraft to exceed the maximum airspeed and manufacturer design loading limitations.
