THE PLT INITIATED A TAKEOFF ON A HOT AFTERNOON WITH 7 PASSENGERS ON BOARD. SHORTLY AFTER LEFT-OFF, 2 WITNESSES OBSERVED WHAT THEY DESCRIBED AS A PUFF OF BLACK SMOKE FROM THE RIGHT ENG. ACCORDING TO WITNESSES, THE ACFT RURNED TO THE LEFT BEFORE CROSSING THE DEPARTURE END OF THE RWY AT LOW ALTITUDE & LOW SPEED. SUBSEQUENTLY, THE ACFT ROLLED RAPIDLY TO THE LEFT & IMPACTED THE GROUND IN A NEAR FLAT ATTITUDE, WITH A HIGH RATE OF SINK, AND SUFFICIENT FORWARD VELOCITY TO SLIDE OR BOUNCE ABOUT 70 FT BEFORE COMING TO REST & BURNING. AN EXAM OF THE WRECKAGE, INCLUDING TEARDOWNS OF BOTH ENGS, REVEALED NO PREIMPACT/MECHANICAL MALFUNCTION OR FAILURE. THE ACFT WAS ESTIMATED TO BE 80 LBS BELOW ITS MAX DESIGN GROSS WT. ITS CENTER OF GRAVITY WAS COMPUTED TO BE 1.45 INCHES AFT OF ITS REAR LIMIT. THE TEMP WAS 101 DEG & THE DENSITY ALTITUDE WAS ABOUT 4000 FT.
