The FAA Computer Testing Supplement for Inspection Authorization (FAA-CT-8080-8D) is a loose-leaf notebook with excerpts from the pertinent regulations (14 CFRs), Airworthiness Directives, charts and tables, all the sample Type Certificate Data Sheets used in the IA test, and the FAA forms with which IA candidates must be familiar. This is the exact book the computer testing centers will issue to applicants taking the IA test.
*You do not need to order this CT-8080-8D testing supplement if already purchasing the IA-6 ("Inspection Authorization Test Prep" by Dale Crane); the IA-6 contains reprints of the testing supplement materials necessary to study for the IA Knowledge Exam (except the figures from AC43-13.1 and 2).
