Analysis

The plt was on x-country flt. Before landing at lakeview, OR, the tachometer failed & began making a noise. At lakeview, the plt disconnected the tachometer & had 7.5 gals of fuel added to 1 tank. He estimated that he had 15 gals of which 3.5 gals were unusable. On the next leg of the flt, he encountered an estimated 15 kt headwind. About 8 miles north of his destination, the eng began running rough & subsequently lost power. At that time, the right fuel gage was reportedly indicating 1/4 to 1/2 full & the left full gage indicated empty. During a night forced landing on a road, the right wing tip hit a tree beside the roadway, the acft veered off the road and went down an embankment. Aprx 1 gal of fuel was found remaining in the acft.
