Analysis

A low pass was made over a fishing pond so the front seat plt could wave at his father. According to the plt's father, the pass was below the level of the tree tops. In attempting to pull up sharply to avoid the trees, the acft was banked steeply and stalled. The acft then hit an unoccuppied house and crashed into a tree. The rear seat plt was the owner-operator of the acft. The front seat plt had about 2200 hrs total flt time & a 'considerable amout of time' in a PA-18-150 since he was a former Alaska bush plt. The front seat plt is presumed to have been at the controls.
