Where is TM Aerial Ace in Diamond?

http://www.psypokes.com/dp/items.php

This is a site that has a list of all items. It says it is found on Route 213. Check it out for this question and many other questions. If you want to ask me more questions feel free to email me at countrygurl0687@hotmai.com. Label the subject as Pokemon Pearl and Diamond question other wise it will get marked a junk. Hope this helps.
