Who paid the initial registration fee? If it was the school/her program, you're out of luck. If it was the team that fundraised and earned the money that purchased the parts and registration, you have some ground to stand on. But either way it will be a favor to the team to get things back and not a requirement for the school to do so. Even if the school holds the parts, they would have to justify why it would go to her classroom rather than to a school sanctioned group that has direct need of the items in question.

I'm really not a fan of the "run to the administration immediately" tactic. It reminds me of 2nd grade when the best solution was to go tell on the kid that was mean to you. Try having a sit down meeting with the teacher and a sponsor and voice your opinions in a professional way that is respectful. You don't want to win this fight by making enemies. Think about the fact that the school will still have a relationship with the team even if that teacher doesn't. I am all to aware of the fact that once you step on a teacher's toes, their department and the one next door will generally not be too friendly with favors in the future (think absences, homework make ups, and test make ups for missing class in March and April).

I know that if I was to have to cut ties with my team, maybe my wife will finally win that fight with me, I would appreciate a conversation rather than my boss sending me an angry email. Even if your relationship with the past coach isn't strong right now, it sounds like the kind of person that you might want some help/favors from in the future considering her department.
