Narrative:

On touch and go at toa, I was followed too closely by an small aircraft who initiated a go around. She was instructed to offset to the left. As a student pilot, she did not understand controller's instructions to offset to left. I offset to the right to avoid a problem and looked up to see the aircraft less than 100 ft away. In my opinion on the preceeding touch and goes, the aircraft was slowly getting closer to the min separation. If we were separated sooner and the student pilot was more conscious of what the controller was saying, the whole incident could have been avoided.

Original NASA ASRS Text

Title: 2 SMA'S HAD AN NMAC IN THE TOUCH AND GO PATTERN AT TOA.

Narrative: ON TOUCH AND GO AT TOA, I WAS FOLLOWED TOO CLOSELY BY AN SMA WHO INITIATED A GAR. SHE WAS INSTRUCTED TO OFFSET TO THE L. AS A STUDENT PLT, SHE DID NOT UNDERSTAND CTLR'S INSTRUCTIONS TO OFFSET TO L. I OFFSET TO THE R TO AVOID A PROBLEM AND LOOKED UP TO SEE THE ACFT LESS THAN 100 FT AWAY. IN MY OPINION ON THE PRECEEDING TOUCH AND GOES, THE ACFT WAS SLOWLY GETTING CLOSER TO THE MIN SEPARATION. IF WE WERE SEPARATED SOONER AND THE STUDENT PLT WAS MORE CONSCIOUS OF WHAT THE CTLR WAS SAYING, THE WHOLE INCIDENT COULD HAVE BEEN AVOIDED.
