One school in the US that comes to mind is Purdue University. See the attactchment below:
Purdue University - Majors
Another possibility is the University of Cincinnati. They have a program in Aerospace engineering that includes aircraft. Some of the engineering programs are 5 year programs (known as Co-op Programs), where the student spends some of each year working in industry while learning and being paid to do so.
University of Cincinnati - Degree Programs
UC has a strong relationship with GE Aviation in Cincinnati. Also, GE and the University of Cincinnati (UC) are actively discussing a possible UC research facility at GE. For decades, UC and GE have collaborated on numerous aerospace research projects, while thousands of GE personnel have graduated from the university, and thousands of UC co-op students have received on-the-job training at GE. However, current discussions are focused on a possible permanent and significant UC presence at or near the GE Aviation Evendale complex.
Good luck to you and your son,
