UNAUTHORIZED PENETRATION OF AIRSPACE. PROX OF ATA.

Narrative

MAR/SUN/92; XY47 AM; I DEPARTED SZP (SANTA PAULA) IN SMA. I HAD REPLACED THE TRANSPONDER ANTENNA AND HAD THE ENCODER; TRANSPONDER AND ALTIMETER CERTIFIED. THE PURPOSE OF THE FLT WAS TO AIR TEST THE EQUIP. DEPARTING SZP RWY 4 I CLBED EBOUND TO 2500 MSL THEN TURNED S TO CROSS S MOUNTAIN INTO SIMI VALLEY OVER MOORPARK; CA; THEN TURNED TO 310 DEGS ABOUT 1 MI S OF THE RIDGE LINE OF S MOUNTAIN. I CALLED PT MUGU APCH AND GAVE MY POS AS 10 NM N OF CMA. RADIO TFC REQUIRED 2 OR 3 CALLS TO ESTABLISH CONTACT ON 124.7 MHZ. APCH THEN GAVE ME A CODE OF XXXX. ABOUT 15 SECONDS LATER APCH CALLED MY POS AS 4.5 NM N OF CMA AT 2500 MSL. THIS WOULD PUT ME IN THE CMA ATA. I ACKNOWLEDGED AND TURNED N AWAY FROM THE ATA AND CTL ZONE. I REALLY FELT I WAS ABOUT 6 MI OR MORE FROM CMA. AT NO TIME DID I HEAD TOWARD CMA; I INTENDED TO SKIRT N OF THE ATA AND CMA CTL ZONE. THE LOS ANGELES SECTIONAL CHART JAN/XX/92 TO JUL/XX/92 DOES NOT SHOW THE CMA CTL ZONE ON ITS N SIDE WHERE SZP AND S MOUNTAIN ARE DEPICTED. THE S SIDE OF THE CHART SHOWS CMA AND ITS RELATED CTL ZONE TO BE ABOUT 2 MI S OF THE BASE OF S MOUNTAIN. HAVING USED SZP AS A BASE FOR 25 YRS AND HAVING INSTRUCTED IN THE AREA I FEEL I WAS CLR OF CMA. THE CMA CTL ZONE SHOULD BE DEPICTED ON THE CHART N SIDE.
