Thanks for all the replies. I filled out a NASA report for both myself and the student. My 3 hours of instruction with him were all cross country. I didn't actually endorse solo flight for the kid, his primary instructor did. I endorsed the cross country flight planning. I documented all the cross country training i did with him on the ground (3 hours worth). I got a call from DFW TRACON, the guy was really nice about it all but said that he had to report it to the FSDO because a flew flights had to change altitude because of the student. The kid actually did fly through DFW's approach path. Any more responses would be appreciated
