Narrative:

On a training mission while preparing a student pilot for his check ride, I told the student to intercept and fly the 326 degree radial from mzb VORTAC. I also told the student to maintain 2500 ft MSL altitude. Since we intercepted the radial just north of mt soledad, and flew outbound from the mzb VORTAC, our flight path carried us through the 'sea wolf' corridor of class B airspace for miramar MCAS. Although I am completely familiar with the airspace, I completely forgot about that segment of the class B and it wasn't until we were north of the area that my student pointed out my mistake while looking at the san terminal area chart. The fact that the flight occurred on a sunday, when miramar MCAS is usually not busy, kept us from having a conflict with departing aircraft. There was no excuse for my mistake. I simply forgot where our course would take us. I will not make this mistake again.

Title: C172 ON TRAINING FLT ENTERS SAN CLASS B AIRSPACE WITHOUT CLRNC.

Narrative: ON A TRAINING MISSION WHILE PREPARING A STUDENT PLT FOR HIS CHK RIDE, I TOLD THE STUDENT TO INTERCEPT AND FLY THE 326 DEG RADIAL FROM MZB VORTAC. I ALSO TOLD THE STUDENT TO MAINTAIN 2500 FT MSL ALT. SINCE WE INTERCEPTED THE RADIAL JUST N OF MT SOLEDAD, AND FLEW OUTBOUND FROM THE MZB VORTAC, OUR FLT PATH CARRIED US THROUGH THE 'SEA WOLF' CORRIDOR OF CLASS B AIRSPACE FOR MIRAMAR MCAS. ALTHOUGH I AM COMPLETELY FAMILIAR WITH THE AIRSPACE, I COMPLETELY FORGOT ABOUT THAT SEGMENT OF THE CLASS B AND IT WASN'T UNTIL WE WERE N OF THE AREA THAT MY STUDENT POINTED OUT MY MISTAKE WHILE LOOKING AT THE SAN TERMINAL AREA CHART. THE FACT THAT THE FLT OCCURRED ON A SUNDAY, WHEN MIRAMAR MCAS IS USUALLY NOT BUSY, KEPT US FROM HAVING A CONFLICT WITH DEPARTING ACFT. THERE WAS NO EXCUSE FOR MY MISTAKE. I SIMPLY FORGOT WHERE OUR COURSE WOULD TAKE US. I WILL NOT MAKE THIS MISTAKE AGAIN.
