Inspection Authorization (IA) is a certification that allows an individual to perform and approve major aircraft inspections, while an Aircraft Maintenance Technician (A&P) holds a certification to perform general maintenance and repairs. The IA credential is typically held by experienced A&P technicians who have additional qualifications. Both roles are essential in the aviation industry, but the IA specifically authorizes the holder to approve aircraft for return to service after inspections.
