Narrative:

During a recent training flight, I was supervising a student on his class B operation procedures. The flight took us to seattle to boeing field. We had radar flight following there and did 5 touch-and-goes at boeing field. After departing boeing, I asked for a frequency change so I could contact renton tower for a class D clearance. In the process of switching frequencys, my student was letting the plane drift dangerously close to getting into class B! After correcting him and watching, I noticed that we were already over the airport right in the middle of class D! I quickly called the tower and received a clearance promptly. The incursion did not cause any problem but I should have been more attentive. Flight instructors need to really be on the ball in busy terminal areas. I have realized from this experience that it is not easy to teach and to talk to controllers at the same time. Be careful not to get locked into doing one thing.

Title: UNAUTH PENETRATION OF AIRSPACE.

Narrative: DURING A RECENT TRAINING FLT, I WAS SUPERVISING A STUDENT ON HIS CLASS B OP PROCS. THE FLT TOOK US TO SEATTLE TO BOEING FIELD. WE HAD RADAR FLT FOLLOWING THERE AND DID 5 TOUCH-AND-GOES AT BOEING FIELD. AFTER DEPARTING BOEING, I ASKED FOR A FREQ CHANGE SO I COULD CONTACT RENTON TWR FOR A CLASS D CLRNC. IN THE PROCESS OF SWITCHING FREQS, MY STUDENT WAS LETTING THE PLANE DRIFT DANGEROUSLY CLOSE TO GETTING INTO CLASS B! AFTER CORRECTING HIM AND WATCHING, I NOTICED THAT WE WERE ALREADY OVER THE ARPT RIGHT IN THE MIDDLE OF CLASS D! I QUICKLY CALLED THE TWR AND RECEIVED A CLRNC PROMPTLY. THE INCURSION DID NOT CAUSE ANY PROB BUT I SHOULD HAVE BEEN MORE ATTENTIVE. FLT INSTRUCTORS NEED TO REALLY BE ON THE BALL IN BUSY TERMINAL AREAS. I HAVE REALIZED FROM THIS EXPERIENCE THAT IT IS NOT EASY TO TEACH AND TO TALK TO CTLRS AT THE SAME TIME. BE CAREFUL NOT TO GET LOCKED INTO DOING ONE THING.
