Analysis

The student plt had just completed her 4th touch-&-go lndg. While climbing after takeoff, the eng lost pwr. The acft was observed to enter a left turn, as if to rtrn back to the rwy, then it entered a stall/spin & crashed aprx 1/2 mi west of the arpt. No preimpact mechanical problems were fnd, except the eng primer was fnd aprx 3/4 of the way out from the locked psn, the ignition switch had svrl electrical contacts broken off & its switch contacts were dirty with carbon deposits. The ignition switch, however, was badly damaged from impact. Neither the primer nor the ignition switch could be verified as having effected the eng problem. The temp & dew point were 70 & 58 deg, respectively. According to carb icing charts, conditions were conducive for carb icing.
