(-23) The actual facts that were causal to the accident remain unclear at this time. However, it appears the aircraft was on a training flight where they were conducting single engine minimum controllable airspeed flight when the aircraft entered a spin and control was lost. The only unusual condition noted during the wreckage inspection was that both the left and right hand fuel selector levers were in the "aux" position with a fuel selector panel placard reading "use of aux tank in level flight only." Two eye witness accounts saw the aircraft spiraling down until impact. Prior to this no witness has been identified that saw the aircraft experiencing trouble or no radio communications were made to indicate mechanical problems. Post accident investigation by the aircraft manufacturer, propeller and engine manufacturer say they found no evidence of mechanical malfunction or failure. A review of the aircraft records show that the required inspections had been accomplished, an airworthiness directives appear to be up-to-date and no recent maintenance activity was accomplished that may have led to a mechanical problem were noted.
