Analysis

The plt stated that he aborted his first takeoff because of reduced acceleration. He taxied back, via a parallel taxiwayand made run-on type takeoff. He said that as the acft climbed to an alt of aprx 50 to 60 ft above the rwy he heard a thud and the airspeed dropped. He said his alt was too low to attempt a turn for the rwy or fly over a two story commercial building ahead of his position. He elected to fly the acft into a large glass window in the commercial building. The eng operated normally during a post accident test run. It was noted however, the carb heat valve could not be moved to the full off position. Weigth & balance calculations indicate the acft was 174 lbs over max gross weight at takeoff.
