AN SMA COMMERCIAL PLT WAS ON 1 OR 2 SIGHT SEEING FLTS ON THE SAME DAY WITH THE POSSIBILITY OF 2 RPTS FOR 1 FLT. 1 RPT DEALS WITH PENETRATING A RESTRICTED AREA THAT WAS 'HOT;' AND THE OTHER WITH PENETRATING THE EDGE OF THE TCA WITHOUT CLRNC. THE RESTRICTED AREAS WERE NOT MENTIONED AS 'HOT' ON HIS DEP ATIS.

Narrative

WHEN I DEPARTED SLC; THERE WERE NO NOTAMS IN EFFECT FOR R-6412 A&B ON ATIS. I FLEW DIRECT TO (U42) SLC #2 AND PICKED UP MY PAX FOR A LCL PLEASURE FLT. DEPARTING SLC #2 I STAYED BELOW THE TCA; AND FLEW S ACROSS THE WESTERN EDGE OF R-6412 A&B AT ABOUT 6500 FT. I HAD RECALLED THAT THESE RESTR AREAS COINCIDED WITH THE TCA; IE; 9000- 10000 FT IN THAT AREA; AND SO I WAS NOT CONCERNED ABOUT THEM AT MY ALT. WHEN RETURNING TO SLC; ATIS WAS RPTING R- 6412 A&B ACTIVE; SURFACE TO 9000 FT. I LOOKED UP THE AREAS ON MY CHART AND FOUND WHAT I HAD THOUGHT WAS IN ERROR: R-6412 B IS 9000-10000 FT AS IS THE TCA; R-6412 A IS SURFACE TO 9000 FT. I DO NOT KNOW WHEN THEY BECAME ACTIVE; AS ATIS WAS RPTING ON MY RETURN TO SLC. ATIS WAS XX ON DEP AND XY ON ARR. MY FAMILIARITY AND RESULTANT COMPLACENCY WERE CONTRIBUTORS TO THIS. AT ONE POINT ON MY TRIP I NOTICED MY ALT AT 7000 FT AND WAS NOT ABLE TO REF MY POS CLOSE ENOUGH/FAST ENOUGH TO SEE IF I WAS FAR ENOUGH S TO BE WHERE THE TCA GOES TO 9000-10000 FT AS IN MY PRIOR DISCUSSION OF R-6412 A&B. I IMMEDIATELY DROPPED THE NOSE TO GET BELOW 7000 FT; HOWEVER; I MAY HAVE ENTERED THE BASE OF THE TCA FOR A COUPLE OF SECONDS. THIS WAS STRICTLY DUE TO TOO MUCH SIGHT-SEEING AND NOT SCANNING MY INSTS ENOUGH. SUPPLEMENTAL INFO FROM ACN 210112: I WAS NOT CLR ON DIRECTION GIVEN BY ATC; 'TO PROCEED NBOUND OVER THE I-15 FREEWAY AT 6000 FT.' WHEN I HAD BEEN IDENTED THEY CALLED ME '5 MI S OF THE MURRAY STACKS;' WHICH ARE JUST E OF THE I-15 FREEWAY. THE MURRAY STACKS STUCK IN MY MIND AND I KEPT THE NOSE POINTED RIGHT TOWARD THEM. WHEN QUESTIONED ON MY POS JUST E OF I-15; ATC LET ME KNOW I SHOULD HAVE BEEN DIRECTLY OVER I-15. THIS TIME I IMMEDIATELY COMPLIED.
