Synopsis
DAY Controllers described an uncoordinated airspace entry event during a training session when the instructor waited too long prior to insuring the required point out had been accomplished.
Narrative
I am currently training in all RADAR sectors at DAY. We were working everything combined; and we started to get busy. There were 2-3 land line calls; I had 3-4 transmissions I needed to make; and I could feel myself starting to get behind. A GLF3 was APREQ'd; with a previous controller; direct his destination instead of an arrival gate. I took the hand off on the GLF3; and when he checked on I told him who I was and told him what approach to expect. I also immediately descended him to 6;000 FT as he was about 2 miles from Columbus' boundary. Columbus owns from the surface to 10;000 FT; and I took the GLF3 at 11;000 FT. I was distracted with other aircraft and land line coordinations; including a point out for parachute jumping from Cincinnati. I was too early in anticipating separation regarding Columbus' airspace. A minute or so later; my Trainer asked me if I descended the GLF3; who is now at 10;700 and descending about 1 mile from the lateral Columbus boundary. I told my trainer that I did and immediately called Columbus for a point-out. By the time Columbus approved the point out the GLF3 was at about 10;500 over the boundary and still descending. The severity of this incident is minimal because there were no aircraft within 15-20 miles of the GLF3; and I did not observe any traffic in Columbus' airspace near the GLF3 as well. In the future; when I get busy; I need to slow down and make sure that my control actions are accurate and timely. I became distracted with land line coordinations and I believe that led to me not realizing the GLF3's proximity to CMH airspace. I need to have a little more patience in situations like this.
Second reporter narrative
I was training a developmental on the combined positions. He took a hand off from Indy Center at 110. He was a little busy and was getting behind. People were talking on the shout lines and calling in at the same time. He descended the aircraft and I didn't hear it. I saw the aircraft at 108 and asked if he started him down and he got on the land line with the other facility to do a point out. By the time that the point out was complete the aircraft was in the other facilities airspace at 103. We have been working with this trainee to call for a coordinator when needed; so I was letting him go to see how far he would let it ride before calling for help. The traffic was getting a little busy but not too bad. I should have gotten a coordinator myself if I couldn't keep up with all of his work. I missed the read back. The trainee is getting pretty close to being ready for checkout and maybe I let myself get a little to comfortable with his work. I will be more diligent in the future.
