While in cruise at 7500 ft MSL at 2600 RPM, I noticed a 300 RPM drop. I pulled carburetor heat, but no detection of carburetor ice so I checked the magnetos. The right magneto was inoperative so I turned towards lwv to make a landing. Suddenly the engine quit. At 7500 ft MSL, I declared an emergency to evansville approach and advised that I had 3 souls and 35 gallons of fuel on board. I made a normal engine-out landing on runway 36 at lwv with no injuries or damage. Mechanics determined that a plastic piece on the magnetos had melted and shorted out causing the engine failure. It was fixed and the aircraft was flown home the next day.

Title: SMA HAS ENG FAILURE AT CRUISE. MAKES SAFE LNDG AT ARPT.
Narrative: WHILE IN CRUISE AT 7500 FT MSL AT 2600 RPM, I NOTICED A 300 RPM DROP. I PULLED CARB HEAT, BUT NO DETECTION OF CARB ICE SO I CHKED THE MAGNETOS. THE R MAGNETO WAS INOP SO I TURNED TOWARDS LWV TO MAKE A LNDG. SUDDENLY THE ENG QUIT. AT 7500 FT MSL, I DECLARED AN EMER TO EVANSVILLE APCH AND ADVISED THAT I HAD 3 SOULS AND 35 GALLONS OF FUEL ON BOARD. I MADE A NORMAL ENG-OUT LNDG ON RWY 36 AT LWV WITH NO INJURIES OR DAMAGE. MECHS DETERMINED THAT A PLASTIC PIECE ON THE MAGNETOS HAD MELTED AND SHORTED OUT CAUSING THE ENG FAILURE. IT WAS FIXED AND THE ACFT WAS FLOWN HOME THE NEXT DAY.
