THE PLT LOST CTL OF THE ACFT IN IFR CONDS AS THE PLANE WAS DSCNDG THRU ABT 6000' MSL, IN AN AREA OF CONVECTIVE ACTIVITY WITH MODERATE TO SEVERE TURBC & UP/DOWN DRAFTS. BOTH WINGS SEPD FM THE ACFT & WRECKAGE WAS SCATTERED OVER AN AREA OF APRX 1.5 MI. CALCULATIONS SHOWED THAT AT THE TIME OF THE ACDNT, THE ACFT'S GROSS WT WAS 29 LBS OVER ITS MAX LIMIT, AND THE CENTER-OF-GRAVITY (CG) WAS ABT 3.3 TO 5.3 INCHES BEHIND THE AFT LIMIT. UNDER THESE CONDS, THE ACFT'S MANEUVERING STABILITY & STICK FORCE PER 'G' CHARACTERISTICS WOULD HAVE BEEN SERIOUSLY DEGRADED. IN TURN, THIS WOULD HAVE ALLOWED THE PLT TO EXCEED THE STRUCTURAL DESIGN LIMITS OF THE ACFT WITH LITTLE OR NO EFFORT. AN EXAM OF THE WRECKAGE DISCLOSED EVIDENCE OF APPARENT FLAP ASYMMETRY, A COND WHICH WAY HAVE OCCURRED DRG THE IN-FLT BREAKUP OF THE ACFT.
