Analysis

Before departing, the plt obtained a wx briefing & was advised of a SIGMET which forecasted severe turbulence below 18,000 ft, strong up/downdrafts, strong surface winds & wind shear near mountains & in passes. He took off with full fuel tanks & aprx 400 lbs of cargo on board. ARTCC reported that the en route portion of the flt was handled routinely. During arrival, the plt contacted the arpt UNICOM for a landing advisory. A king air plt was arriving at about the same time & asked the Aerostar plt if he was making a full stop. The Aerostar plt replied that he was. The king air plt lost sight of the Aerostar & began a 360 deg turn. He asked the Aerostar plt to advise of his position, & shortly thereafter,the Aerostar plt transmitted 3 mayday calls. Reportedly, the acft nosed up & went into a steep rgt bank just bfr impact. No preimpact mechanical failure/malfunction was found. There was evidence that most of the cargo was in the baggage compartment (limited to 240 lbs) & could have moved the CG well beyond the aft limit. Elev trim fnd full nose down.
