What is the FAA AC 20 27G

The FAA AC 20 27G, or Advisory Circular 20 27G, provides guidelines for the acceptance of amateur-built aircraft. This document outlines the standards and practices that must be followed to ensure these aircraft meet safety and regulatory requirements. It is essential for builders and operators of experimental aircraft to understand this advisory circular, as it lays the foundation for compliance with Federal Aviation Administration (FAA) regulations. The AC 20 27G serves as a reference point for the design, construction, and operation of amateur-built aircraft, ensuring that they are safe for flight and adhere to the necessary legal frameworks.

How to Use the FAA AC 20 27G

Using the FAA AC 20 27G involves familiarizing oneself with its contents and applying its guidelines during the construction and certification of amateur-built aircraft. Builders should start by reviewing the document to understand the requirements for materials, design, and safety protocols. It is important to maintain detailed records throughout the building process, including plans, modifications, and inspections. Following the guidelines in AC 20 27G helps ensure that the aircraft can be certified as airworthy and legally operated under FAA regulations.

Key Elements of the FAA AC 20 27G

Several key elements are outlined in the FAA AC 20 27G that builders must pay attention to. These include:

• Design Standards: Specifications for materials and construction methods that ensure safety and structural integrity.
• Documentation: Requirements for keeping records of the building process, including plans and modifications.
• Inspections: Guidelines for conducting and documenting inspections during the building process.
• Certification Process: Steps necessary to obtain an airworthiness certificate for the completed aircraft.

Steps to Complete the FAA AC 20 27G

Completing the FAA AC 20 27G involves several important steps:

1. Review the advisory circular thoroughly to understand all requirements.
2. Gather necessary materials and tools for building the aircraft.
3. Document each phase of construction, including any changes made to the original plans.
4. Schedule inspections at key milestones to ensure compliance with safety standards.
5. Prepare for the final inspection and certification by compiling all documentation.

Legal Use of the FAA AC 20 27G

The legal use of the FAA AC 20 27G is crucial for ensuring that amateur-built aircraft are compliant with FAA regulations. Builders must adhere to the guidelines set forth in the advisory circular to avoid legal issues. This includes obtaining the necessary permits and certifications, as well as ensuring that the aircraft meets the safety standards outlined in the document. Failure to comply with these regulations can result in penalties, including the inability to legally operate the aircraft.

Examples of Using the FAA AC 20 27G

Examples of how the FAA AC 20 27G is applied in practice include:

• A builder following the guidelines to construct a homebuilt aircraft, ensuring all materials meet safety standards.
• An individual documenting the construction process to prepare for the FAA inspection.
• Builders collaborating with experienced professionals to ensure compliance with the advisory circular.
