Thanks for the responses guys.

Haven't heard anything from anyone. I did see the asst. chief today and all he asked was how my student was...my student was really upset/thought he was in major trouble for the incident. He didn't mention anything else about it.

Another instructor said his manager/supervisor told him that stuff happens and nothing will happen.

About the chief instructor asking the FAA about an investigation: I did not hear straight out of his mouth, the records lady said she heard him ask it. Could be a rumor for all I know as I haven't heard anything from management in almost a week. Really appreciate the responses.
