Analysis

Two fully qualified single engine plts were in the acft at the time of the accidnet. The acft was observed making low passes near the airport after takeoff. One plt's mother lived near the accident site. The acft was in a steep banked right turn when the right wing tip impacted the surface followed by the aircraft impacting the surface with the wreckage continuing thru wires, fence and the pipe storage racks. The impact demolished the aircraft and fatally injured the plts. It could not be determined which of the plts was flying the acft at the time of impact.
