Welcome To AvSource auditing group

We’ve Walked in Your Shoes That’s why our work actually works.

Who We Are?

We’re not just auditors or manual writers. We’ve managed operations, flown the trips, fixed the aircraft, and gone through audits ourselves. That’s why everything we deliver is practical, audit-smart, and built for the real world—not just the bookshelf.

Got questions? We’re here before, during, and long after the job is done.

Why Do Operators Turn to Us?

Because documentation is often the biggest roadblock during an IS-BAO audit. Operators tell us:

I don’t even know where and how to start with manuals.

Looks like we may need to rewrite the manuals we have.

We bought templates, but they don’t match our operation.

I don’t have extra time to fix documents on top of running flights.

We get it! You’re busy running a safe operation so writing compliance documents shouldn’t be your full-time job.

We Write the Manuals, You Focus on Operations

AvSource specializes in IS-BAO-compliant documentation. No long-term commitment, just easy-to-use manuals that are tailored to your operation, and you own them.

We build:

  • Safety Management System (SMS) Manuals
  • Emergency Response Plans (ERP)
  • Flight Operations Manuals (FOM)
  • Pre-audit documentation packages

Our manuals are aligned with current IS-BAO protocols, ICAO Annex 19, and FAA AC 120-92B. They’re written to be readable, easy to update, and formatted the way you like.
