This book provides aviation maintenance technicians (AMTs) with all the resources needed to pass the FAA's exam for inspection authorization, & helps become familiar with the privileges & limitations of the highest level of maintenance certification. This book is an important source for all AMTs seeking to add Inspection Authorization (IA) to their qualifications, as well as AMT schools preparing students for the IA test. All IA candidates must take and pass the FAA’s IA Knowledge Exam.The IA exam is different from other FAA exams in that it remains a “closed test”— the exact database of questions is not available to the public—which makes the IA Test Prep a great way to prepare for this exam. The more than 450 sample questions typify those that candidates are likely to encounter when taking the IA Exam. The questions & answer choices are supported with explanations, and the FAA references from which the questions are derived are identified for students who wish to study them further.
