Analysis

The crew were advised that the acft's vacuum pump system was inoperative due to a sheared pump driveshaft. The copilot had stated that fss had forecast 25,000 ft broken & he did not feel he would need the pump. At 1735 the plt contacted center & requested radar advisories to brownsville. At 1812 the pilot requested & was granted permission to deviate around a cell. 12 minutes later the target disappeared. Wreckage examination revealed that the tail & right wing had separated in flight. There was a vip level 1 echo within 5 mi east & a vip level 3 echo within 10 mi se of the accident site. Moderate to severe convective turbulence & up & down drafts would have been present below 10,000 ft. the plt's liver tissue produced 96 mg% ethyl alcohol & mixed tisse fluid produced 112 mg%.
