WITNESSES OBSERVED THE AERIAL APPLICATION ACFT AT 30-50 FT AGL OVER THE RWY BEFORE IT PULLED UP STEEPLY, ROLLED AND ENTERED A NEAR VERTICAL UNCONTROLLED DESCENT TO IMPACT. A POST CRASH FIRE CONSUMED MOST OF THE WRECKAGE. DESPITE OPEN LEVEL TERRAIN OFF THE END OF THE RWY, THE PLT ATTEMPTED TO RETURN TO THE RWY FOR A FORCED LDG. A METALLURGICAL EXAMINATION OF THE FAILED CYLINDER HEAD REVEALED EXTENSIVE FATIGUE CRACKING INITIATED IN THE CYLINDER LINER THREAD ROOTS AND BETWEEN THE COOLING FINS AT THE TOP OF THE CYLINDER.
