Analysis

The acft departed nashville, TN, for a flt to aspen, CO. The plts made one refueling stop at chanute, KS. The plts were unable to land at aspen or a nearby alternate arpt (eagle, CO) and elected to return back to the denver area. The plts indicated to an ARTCC controller that they were low fuel. Before they could reach an arpt the plt told the controller they had eng failure and thought they had run out of fuel. During the emergency descent the acft struck an electrical power pole, power lines and then the ground. Inspection of the acft revealed 2 to 3 gallons of fuel remaining in each main fuel tank.
