Narrative:
En route between mhv to rnm via L70, transitioning north of sna below the floor of class C airspace at approximately 9 mi nne of sna. Possible airspace intrusion into sna class C airspace at boundary between 2000-3500 ft floor of the north central and northeast portion of outer ring. While in cruise flight at 1900 ft MSL in the north central outer ring of sna class C airspace and in the process of determining that I was clear of the disneyland tfr and trying to locate the center of the tfr on the los angeles sectional, los angeles inset (neither of which depicts disneyland), I inadvertently climbed to 2300 ft by which time I was within the northeast section of the class C which has a floor of 3500 ft MSL. I may have entered the class C near the border of the 2000-3500 ft floor, but by the time I noticed, I was well within the northeast section of sna. Because this tfr was not near my intended route, I had no graphical tfr map, only a text version of fdc 3/2123, and had not briefed this tfr. Quickly identifiable text information and depiction of disneyland on the sectional would reduce the recognition time especially during single pilot operations.

Title: AN AS350 B3 PLT ACCIDENTALLY PENETRATES THE FLOOR OF THE CLASS C AIRSPACE WITHOUT CLRNC WHEN 9 NM NNE OF SNA, CA.
Narrative: ENRTE BTWN MHV TO RNM VIA L70, TRANSITIONING N OF SNA BELOW THE FLOOR OF CLASS C AIRSPACE AT APPROX 9 MI NNE OF SNA. POSSIBLE AIRSPACE INTRUSION INTO SNA CLASS C AIRSPACE AT BOUNDARY BTWN 2000-3500 FT FLOOR OF THE NORTH CENTRAL AND NE PORTION OF OUTER RING. WHILE IN CRUISE FLT AT 1900 FT MSL IN THE NORTH CENTRAL OUTER RING OF SNA CLASS C AIRSPACE AND IN THE PROCESS OF DETERMINING THAT I WAS CLR OF THE DISNEYLAND TFR AND TRYING TO LOCATE THE CTR OF THE TFR ON THE LOS ANGELES SECTIONAL, LOS ANGELES INSET (NEITHER OF WHICH DEPICTS DISNEYLAND), I INADVERTENTLY CLBED TO 2300 FT BY WHICH TIME I WAS WITHIN THE NE SECTION OF THE CLASS C WHICH HAS A FLOOR OF 3500 FT MSL. I MAY HAVE ENTERED THE CLASS C NEAR THE BORDER OF THE 2000-3500 FT FLOOR, BUT BY THE TIME I NOTICED, I WAS WELL WITHIN THE NE SECTION OF SNA. BECAUSE THIS TFR WAS NOT NEAR MY INTENDED RTE, I HAD NO GRAPHICAL TFR MAP, ONLY A TEXT VERSION OF FDC 3/2123, AND HAD NOT BRIEFED THIS TFR. QUICKLY IDENTIFIABLE TEXT INFO AND DEPICTION OF DISNEYLAND ON THE SECTIONAL WOULD REDUCE THE RECOGNITION TIME ESPECIALLY DURING SINGLE PLT OPS.
