Narrative:

Departing aiy for N44. I inadvertently climbed through the floor of the arsa. While in contact with departure control shortly after takeoff at approximately 800' MSL, I called for clearance through the arsa and was advised to remain clear of the arsa. Approximately 30 seconds later while at approximately 1000', departure came back with squawk code and I was asked to identify. Inadvertently taking that as permission to enter the arsa, I continued to climb through the floor of the arsa and was advised shortly after that he still wanted me clear of the arsa. I asked if he wanted me to go back and he asked for a mode C verification. With him using my full call sign, I was told to proceed on course. I must have took for granted that my full call sign was called back after receiving the squawk code. It was my 1ST time departing a satellite airport and I was a little nervous departing there at night. I'm going to schedule some dual instruction in and out of that airport to avoid any future mistakes.

Title: SMA PENETRATES ARSA ASSUMING CLRNC RECEIVED BECAUSE ATC GAVE SQUAWK CODE AFTER INITIAL CALLUP.

Narrative: DEPARTING AIY FOR N44. I INADVERTENTLY CLIMBED THROUGH THE FLOOR OF THE ARSA. WHILE IN CONTACT WITH DEP CTL SHORTLY AFTER TKOF AT APPROX 800' MSL, I CALLED FOR CLRNC THROUGH THE ARSA AND WAS ADVISED TO REMAIN CLEAR OF THE ARSA. APPROX 30 SECONDS LATER WHILE AT APPROX 1000', DEP CAME BACK WITH SQUAWK CODE AND I WAS ASKED TO IDENT. INADVERTENTLY TAKING THAT AS PERMISSION TO ENTER THE ARSA, I CONTINUED TO CLIMB THROUGH THE FLOOR OF THE ARSA AND WAS ADVISED SHORTLY AFTER THAT HE STILL WANTED ME CLEAR OF THE ARSA. I ASKED IF HE WANTED ME TO GO BACK AND HE ASKED FOR A MODE C VERIFICATION. WITH HIM USING MY FULL CALL SIGN, I WAS TOLD TO PROCEED ON COURSE. I MUST HAVE TOOK FOR GRANTED THAT MY FULL CALL SIGN WAS CALLED BACK AFTER RECEIVING THE SQUAWK CODE. IT WAS MY 1ST TIME DEPARTING A SATELLITE ARPT AND I WAS A LITTLE NERVOUS DEPARTING THERE AT NIGHT. I'M GOING TO SCHEDULE SOME DUAL INSTRUCTION IN AND OUT OF THAT ARPT TO AVOID ANY FUTURE MISTAKES.
