FAA AC 20-150 Composite Repair Structural Testing
The FAA Advisory Circular (AC) 20-150 is a critical reference for the structural integrity of composite repairs in civil aviation. This service ensures that any repair or modification to a composite structure adheres to strict standards set forth by the Federal Aviation Administration (FAA). These guidelines are essential for maintaining airworthiness and ensuring passenger safety.
Composite materials, such as carbon fiber reinforced polymers (CFRP), have become increasingly popular in aerospace due to their lightweight properties. However, these materials present unique challenges when it comes to repair and maintenance. The FAA AC 20-150 provides detailed procedures for assessing the structural integrity of composite repairs, including:
- Visual inspection
- Destructive testing (if necessary)
- Nondestructive evaluation methods such as ultrasonic testing and radiography
- Loading tests to simulate flight conditions
- Mechanical testing to assess strength and fatigue properties
The service involves a rigorous process that begins with the initial inspection of the repair site. This includes checking for any visible damage, cracks, or delamination. If these issues are present, they must be addressed before proceeding with repairs.
Once the repair is completed, it undergoes multiple stages of testing to ensure its structural integrity. These tests include:
- Visual inspection
- Destructive and nondestructive evaluation methods
- Loading tests that simulate operational loads
- Mechanical testing to assess tensile, compressive, and shear strength
The primary goal of this service is to provide comprehensive data that supports the airworthiness of an aircraft. By adhering strictly to FAA AC 20-150 guidelines, we ensure that any composite repair meets or exceeds industry standards.
| Test Method | Description | Purpose |
|---|---|---|
| Visual Inspection | Checking the visible condition of the repaired area | To identify any remaining damage or imperfections |
| NDE Methods (Ultrasonic, Radiography) | Evaluating internal structure without damaging it | To ensure no hidden defects are present |
| Loading Tests | Simulating operational loads on the repair site | To verify structural integrity under stress |
| Mechanical Testing | Assessing tensile, compressive, and shear strength | To confirm material properties meet specifications |
The process also involves detailed documentation of all tests conducted. This includes photographs, videos, and reports that outline the findings from each stage of testing.
