Analysis

The plt, who was the mechanic for the acft & who possesses FAA inspection authorization, was familiar with this acft and had flown it the day before the accident. The plt failed to refuel the acft after making two additional flts. The main fuel tank gages were reportedly accurate. On the return leg of the plt's last flt, as the acft approached the destination arpt, both engines lost power. The plt turned the acft toward the arpt and the right eng suddenly obtained fuel and momentarily produced power. The acft was below VMC at the time. The acft rolled left, acquired a near vertical attitude and control was lost. The acft then descended to the terrain and crashed about 1000 yards from the arpt.
