Analysis

Radar track showed acft made normal climb on course from airport (elev 4488 ft MSL) to 9400 ft. MSL, then executed a left turn of about 90 degrees, climbing to 9700 ft MSL as shown by next-to-last radar tgt. 29 secs later, final radar tgt showed 6900 ft MSL. Witnesses sighted acft spinning with pieces coming off before striking ground. Weather study indicated convective clouds in area from 2000 ft to 10000 ft MSL. Investigation revealed rt wing and empennage separated in aerodynamic overload failure mode. Max design maneuvering speed calculated to be 123 knots at existing acft weight. Circumstances indicate plt lost control of acft while maneuvering to avoid/reverse course out of clouds, overstressed airframe during recovery attempt.
