At about 1359 Pacific time, a Cessna T210M crashed near Groveland, killing the pilot and passenger. Controllers lost radar and radio contact when the airplane was cruising at 12,500 feet en route from Fullerton to Carson City, Nev. The crankcase had a 3-inch-diameter hole in it above cylinder No. 3 and a fractured connecting rod piece. The propeller showed evidence that it was windmilling at the time of impact.
