On occasion they just want to ask a question about your operation or why you did something in a particular manner, even if there was no violation. I've had that also. I have had to call a few times, over many years. It worked out fine in each case. If you do not call, you are then essentially/effectively forcing the FAA's hand, which can trigger a formal investigation. That's typically when things get ugly. I am not making any recommendations, except to send the NASA form, just sharing my experience. Good luck!
