After topping off fuel tanks at laconia,nh, I flew over lake winnipesaukee at 2000' MSL. After climbing to 3500 ft MSL I turned on a westerly heading towards the gunstock ski area, which is approximately 5 mi. Southeast of laconia airport while 3 to 4 mi east of the ski area, I began to demonstrate slow flight and relative ground speed to my passenger by flying into the wind coming out of the west. I intended to over fly the ski area at 3500' MSL and permit 1100' for terrain clearance. While 2 to 3 mi east of the peak, I noticed that the right fuel gauge indicated an empty tank. I decided the problem was a malfunctioning fuel gauge but began a precautionary descent towards laconia's pattern altitude in order to land and visually check the fuel level in the tank. At the time I crossed the peak, I was surprised to see the top of the mountain closer than expected. At the time my altimeter read 2800' MSL, a terrain clearance of 416'.

Title: GA SMA DISTR BY ACFT EQUIPMENT PROBLEM FLEW BELOW LEGAL LIMIT OVER TERRAIN.
Narrative: AFTER TOPPING OFF FUEL TANKS AT LACONIA,NH, I FLEW OVER LAKE WINNIPESAUKEE AT 2000' MSL. AFTER CLIMBING TO 3500 FT MSL I TURNED ON A WESTERLY HEADING TOWARDS THE GUNSTOCK SKI AREA, WHICH IS APPROX 5 MI. SE OF LACONIA ARPT WHILE 3 TO 4 MI EAST OF THE SKI AREA, I BEGAN TO DEMONSTRATE SLOW FLT AND RELATIVE GND SPEED TO MY PASSENGER BY FLYING INTO THE WIND COMING OUT OF THE WEST. I INTENDED TO OVER FLY THE SKI AREA AT 3500' MSL AND PERMIT 1100' FOR TERRAIN CLRNC. WHILE 2 TO 3 MI EAST OF THE PEAK, I NOTICED THAT THE R FUEL GAUGE INDICATED AN EMPTY TANK. I DECIDED THE PROBLEM WAS A MALFUNCTIONING FUEL GAUGE BUT BEGAN A PRECAUTIONARY DESCENT TOWARDS LACONIA'S PATTERN ALTITUDE IN ORDER TO LAND AND VISUALLY CHECK THE FUEL LEVEL IN THE TANK. AT THE TIME I CROSSED THE PEAK, I WAS SURPRISED TO SEE THE TOP OF THE MOUNTAIN CLOSER THAN EXPECTED. AT THE TIME MY ALTIMETER READ 2800' MSL, A TERRAIN CLRNC OF 416'.
