Converting Your Overseas Pilot Licence:
A Six-Part CASA Guide
Part 2 – Applying for an ARN, Licence, and AIC
The Paper Trail Begins With You
Once you’ve confirmed you’re eligible to convert your licence, it’s time to start the formal process. Everything begins with the ARN—your unique identifier with CASA. Without it, you can’t lodge forms, book exams, or be issued a licence.
This is also the stage where your security check begins, which can take several weeks. Starting now means avoiding delays later.
What You’ll Learn in This Step:
- 🆔 How to apply for your Aviation Reference Number (ARN)
- 📄 What CASA Form 61-4A is and how to fill it
- 🔐 Why a security clearance (ASIC or AVID) is a must for your licence
Step 1: Apply for Your ARN
The Aviation Reference Number (ARN) is your CASA pilot ID. It links all your activity—applications, exams, licences, flight test bookings—to one unique number.
Apply online through CASA’s portal here:
🔗 Apply for an ARN – CASA

Step 3: Apply for Your Security Clearance
To be issued a CASA licence, you’ll need an aviation security check—this comes in two forms.
Time to process:
⏳ 4–6 weeks. Apply early!
🔗 Apply through CASA-accredited providers like AusCheck or AVID/ASIC card issuers linked on the CASA site.
Frequently Asked Questions
What is an ARN?
Your Aviation Reference Number is a personal ID code issued by CASA that you’ll use for all licensing and communication.
Can I submit Form 61-4A without my ARN?
No. You must include your ARN on the form—it’s essential for processing.
What’s the difference between an ASIC and an AVID?
ASICs allow you access to secure airport areas and are required for commercial flying. AVIDs are sufficient for general aviation pilots without airport access needs.
Do I need a CASA medical certificate before this step?
Not yet—but you will need a current CASA medical before your licence is officially issued or validated.
How long does the ASIC/AVID process take?
Between 4 and 6 weeks, so it’s smart to apply early in the conversion process to avoid bottlenecks later.
