Analysis

After takeoff, the flt progressed normally, except one ARTCC controller had difficulty communicating with the plt during the early part of the flt. After cruising at 11,000 ft for aprx 2 hrs, the plt obtained updated wx info & requested clearance to descend to 9000 ft to avoid build-ups. He was cleared to deviate & descend at his discretion & he acknowledged. Shortly thereafter, radar & radio contact were lost. An in-flt break-up occurred & the wreckage was scattered over a wide area. The horizontal stabilizers were found aprx 2-1/2 mi from the main wreckage. There was evidence that they had failed in a slight up & rearward direction. No pre-accident failures were found. Wx data showed that the acft likely penetrated the edge of a strong (vip level 3) thunderstorm with severe turbulence, rain & up/downdrafts. A check of the plt's blood showed a small amount of alcohol (0.05%); however, the amount due to possible putrefaction or contamination was not determined.
