FAA Advisory Circulars Explained: FAA AC 0056B, FAA Codes, and Aviation Safety Programs
Introduction: What Are FAA Advisory Circulars?
Have you ever wondered what FAA Advisory Circulars are and why they matter?
In the world of aviation and quality management, these circulars are essential guides. They help organizations meet Federal Aviation Administration (FAA) safety and compliance standards.
In this article, you’ll learn about FAA AC 0056B, FAA Codes, and other important circulars like AC43-13-1B and AC 00-46. Let’s break them down one by one in simple, clear terms.
What Is FAA AC 0056B?
FAA AC 0056B is an official Advisory Circular issued by the Federal Aviation Administration (FAA).
It outlines the accreditation requirements for aviation suppliers and distributors.
In other words, it sets the standard for how aviation parts distributors should manage quality, documentation, and traceability.
Organizations that comply with FAA AC 0056B prove that they have:
- A strong quality management system.
- Reliable supplier evaluation processes.
- Proper document and parts traceability.
- Commitment to continuous improvement.
This circular aligns closely with AS9120, ISO 9001, and TAC 2000, making it essential for aviation businesses aiming for top-level quality assurance.
What Is an FAA Advisory Circular?
An FAA Advisory Circular (AC) is a document that explains how to meet FAA regulations effectively.
These circulars are not laws, but they describe acceptable methods for complying with aviation standards. The FAA uses ACs to help pilots, maintenance facilities, manufacturers, and suppliers operate safely and efficiently.
Simply put, FAA Advisory Circulars serve as the bridge between the regulations and how you apply them in real operations.
What Is an FAA Code?
An FAA Code identifies specific aircraft, facilities, or regulatory references within the FAA system.
There are several types of FAA Codes, including:
- Aircraft Type Codes: Identify aircraft models.
- Airport Location Identifiers: Identify airports.
- Certificate Numbers: Identify airmen, maintenance organizations, and repair stations.
Understanding these codes ensures accuracy in documentation, traceability, and compliance during audits or inspections.
What Is the FAA AC 00-46 Aviation Safety Reporting Program?
FAA AC 00-46 introduces the Aviation Safety Reporting Program (ASRP). This program encourages aviation professionals to report safety hazards and incidents voluntarily.
The goal is to promote a just safety culture where people report problems without fear of punishment.
NASA collects and reviews these reports, helping the FAA identify safety trends and prevent future accidents.
This circular is key to maintaining open communication and proactive safety management in aviation.
What Is FAA AC43-13-1B?
FAA AC43-13-1B is one of the most referenced FAA Advisory Circulars in aircraft maintenance.
It provides acceptable methods and techniques for aircraft inspection and repair when manufacturer data is unavailable.
This circular covers:
- Structural repairs
- Systems and components maintenance
- Corrosion control
- Materials and repair practices
Mechanics often call AC43-13-1B the “Mechanic’s Bible” because it helps ensure that all repairs meet FAA airworthiness standards.
What Does AC Stand For in Aviation?
In aviation, AC stands for Advisory Circular.
An Advisory Circular provides non-mandatory guidance on compliance, safety, and maintenance practices.
Even though ACs are not legally required, following them strengthens compliance, safety, and audit readiness.
What Are the Four Major Categories of Aircraft per FAA?
The FAA classifies aircraft into four main categories:
- Airplanes – Fixed-wing aircraft powered by engines or propellers.
- Rotorcraft – Aircraft with rotating blades, such as helicopters.
- Gliders – Aircraft that fly without engines, using lift and air currents.
- Lighter-than-Air Aircraft – Balloons and airships that float using lighter gases.
Each category has its own certification and maintenance standards defined by the FAA.
Why FAA Advisory Circulars Matter
FAA Advisory Circulars play a critical role in aviation safety and compliance. They ensure that every organization operates under consistent, FAA-approved practices.
For companies aiming for ISO 9001, AS9120, or TAC 2000 certification, understanding these circulars is vital.
They help you document, implement, and maintain quality systems that meet FAA expectations.
At Quality Innovations, we help aviation businesses interpret FAA standards, prepare documentation, and achieve compliance smoothly and efficiently.
Frequently Asked Questions (FAQs)
Q1: Are FAA Advisory Circulars mandatory?
No. FAA Advisory Circulars are guidelines, not legal requirements. However, following them ensures compliance with FAA expectations and builds credibility during audits.
Q2: How do I comply with FAA AC 0056B?
You’ll need to establish a documented quality system that meets AC 0056B requirements. Many organizations also align this with ISO 9001 or AS9120 standards.
Q3: Does FAA AC43-13-1B replace manufacturer data?
It can only be used when manufacturer data is unavailable. Always ensure compliance with FAA-approved repair practices.
Q4: Why is AC 00-46 important for aviation safety?
It promotes voluntary safety reporting, helping identify risks and prevent future incidents across the aviation industry.
Conclusion
FAA Advisory Circulars such as AC 0056B, AC43-13-1B, and AC 00-46 are the foundation of aviation compliance and safety.
They guide organizations on best practices for quality management, maintenance, and operational safety.
