Narrative:

I am a CFI and during a recent training cross country flight from oakland to angwin and back to oakland, I diverted my student to sonoma valley airport. As part of the training I wanted him to figure out how to enter a pattern at a strange uncontrolled airport and land there safely. As part of the training I had him look on the chart in the airport facility directory for pattern direction tpa's and notes on the airport. He did and we did a touch and go on runway 25 and departed to the south. It wasn't until a few days later (while on a different training flight to sonoma) that I read the notes to discover that the touch and goes are prohibited at sonoma valley airport. In my excitement to teach this student all I could about diverting, I forgot to double-check him for accuracy. As the CFI, I should have researched the airport before diverting there, instead of diverting to the most convenient airport. This won't happen again, and I apologize to anyone at the airport that we might have upset. (Nobody else was in the pattern, and no other people were on the ground as far as we could tell.)

Title: A C152 INSTRUCTOR PLT CHOOSES TO DIVERT TO SONOMA VALLEY ARPT DURING A XCOUNTRY TRAINING FLT FOR A TOUCH AND GO. LATER IT WAS FOUND THAT WITHIN THE ARPT FACILITY DIRECTORY PUB THAT TOUCH AND GOES ARE NOT AUTH AT 0Q3, CA.

Narrative: I AM A CFI AND DURING A RECENT TRAINING XCOUNTRY FLT FROM OAKLAND TO ANGWIN AND BACK TO OAKLAND, I DIVERTED MY STUDENT TO SONOMA VALLEY ARPT. AS PART OF THE TRAINING I WANTED HIM TO FIGURE OUT HOW TO ENTER A PATTERN AT A STRANGE UNCTLED ARPT AND LAND THERE SAFELY. AS PART OF THE TRAINING I HAD HIM LOOK ON THE CHART IN THE ARPT FACILITY DIRECTORY FOR PATTERN DIRECTION TPA'S AND NOTES ON THE ARPT. HE DID AND WE DID A TOUCH AND GO ON RWY 25 AND DEPARTED TO THE S. IT WASN'T UNTIL A FEW DAYS LATER (WHILE ON A DIFFERENT TRAINING FLT TO SONOMA) THAT I READ THE NOTES TO DISCOVER THAT THE TOUCH AND GOES ARE PROHIBITED AT SONOMA VALLEY ARPT. IN MY EXCITEMENT TO TEACH THIS STUDENT ALL I COULD ABOUT DIVERTING, I FORGOT TO DOUBLE-CHK HIM FOR ACCURACY. AS THE CFI, I SHOULD HAVE RESEARCHED THE ARPT BEFORE DIVERTING THERE, INSTEAD OF DIVERTING TO THE MOST CONVENIENT ARPT. THIS WON'T HAPPEN AGAIN, AND I APOLOGIZE TO ANYONE AT THE ARPT THAT WE MIGHT HAVE UPSET. (NOBODY ELSE WAS IN THE PATTERN, AND NO OTHER PEOPLE WERE ON THE GND AS FAR AS WE COULD TELL.)
