A witness rprtd that drg takeoff, the acft rotated to a steep (nose up) attitude, & immediately after lift-off, the plt made a steep left turn & entered a downwind for lndg on the same rwy. He described the downwind as being a little tighter than normal & a little low. He noted a pwr rdcn when the acft was abeam the rwy threshold. Rprtdly, the plt madea turn to base leg & bgn to overshoot the final apch path. According to the witness, the acft entered a very steep base to final turn, then stalled & bgn to spin. Rprtdly, the spin stopped after aprx 1/2 turn, but the acft struck the gnd bfr the plt could recover. The acft was badly dmgd by impact & fire. No preimpact mech problem was fnd. A toxicology rprt indcd the available specimen of the plt's blood was diluted with otr body fluids. The specimen tested positive for alcohol, but the plt's blood/alcohol lvl was not determined. A test of his urine showed an alcohol lvl of 0.256% (256 ml/dl). Phenylpropanolamine (a decongestant) was detectted in his urine, but none was fnd in his blood.
