ExploreAbout this exam
The ANAC IOAR credential relates to individuals who act on behalf of Brazil's civil aviation authority, ANAC, in airworthiness inspection and oversight work. It suits experienced airworthiness engineers, maintenance post-holders, quality auditors and regulatory inspectors who already know aircraft certification and continuing airworthiness practice and want to be assessed against ANAC's expectations for delegated or representative oversight duties. The exam is multiple choice and samples the whole regulatory role rather than a single technical specialty. Expect questions on RBAC rules governing airworthiness and continuing airworthiness, certification and approval processes, maintenance programme management, inspection and audit technique, organisation certification and oversight, safety management and occurrence reporting, human factors and safety culture, and ICAO harmonisation. Preparation should start from the current RBAC texts and ANAC guidance material, since questions are framed in the language of the regulation. Work through each domain, then practise applying rules to realistic scenarios: a finding from a station visit, a proposed maintenance programme change, a repeat occurrence. Candidates who only memorise clauses tend to struggle with the judgement questions. ANAC publishes current administrative details such as fees, scheduling and pass criteria on its own website; this page is independent study material and is not affiliated with or endorsed by ANAC. Always confirm requirements against official sources before applying.
What you'll study
About BR-ANAC-IOAR preparation
What is the exam format?
It is a multiple-choice examination covering all eight domains in the published blueprint. Questions are scenario-based as well as factual, so you must apply regulations rather than just recall them. Confirm the current delivery method, language options and any permitted reference material with ANAC, because administrative arrangements change.
How long is the exam and how many questions are there?
ANAC sets and publishes the current question count, time allowance and sitting arrangements. We deliberately do not quote figures here because they change and we cannot verify them. Check the official ANAC page for the IOAR credential before you plan your study schedule or book a date.
What score do I need to pass?
The passing standard is set by ANAC and published in its official examination documentation. Do not rely on second-hand figures from forums or training providers. Confirm the current criterion directly with ANAC, and aim to be comfortably above any minimum by covering every domain rather than excelling in a few.
Can I retake the exam if I fail?
Retake rules, waiting periods and any limits on attempts are administrative matters set by ANAC. They are not fixed across time, so check the official source for the current policy. Practically, treat a first attempt as diagnostic: note which domains cost you marks and rebuild your study plan around those before reapplying.
How difficult is it?
It is a professional-level exam aimed at people already working in airworthiness. The difficulty is breadth plus judgement: you need regulatory precision across certification, maintenance and oversight, and the ability to reason about incomplete scenarios. Candidates with several years of hands-on airworthiness or quality experience generally find it demanding but fair.
In what order should I study the domains?
Start with the RBAC regulatory framework, because every other domain uses its vocabulary. Then take certification and continuing airworthiness together, followed by inspection and audit technique and organisation oversight. Finish with safety management, occurrence reporting, human factors and ICAO harmonisation, which are lighter in weight but easy marks if revised close to the exam.
Why do candidates fail?
The usual causes are shallow regulation knowledge, confusing certification with continuing airworthiness responsibilities, and weak audit reasoning, such as failing to distinguish a finding from an observation or to identify the correct corrective-action path. Others misread scenario questions. Practise explaining, in writing, why an answer is correct under a specific RBAC provision.
How should I prepare in the final weeks?
Move from reading to retrieval. Work scenario questions under time pressure, then review every wrong answer against the actual regulatory text. Summarise each domain on one page in your own words and test yourself from those summaries. Re-read occurrence reporting and human factors last, since they are commonly under-revised relative to their weight.
