Which maintenance step focuses on the initial establishment of a corrosion control program?

The focus of the maintenance step that emphasizes the initial establishment of a corrosion control program is critical for ensuring long-term effectiveness in managing corrosion in avionics and other aircraft components. This step involves developing a structured approach to prevent corrosion, which may include creating policies, procedures, and training programs tailored to address specific risks of corrosion in different environments.

The establishment of a corrosion control maintenance program lays the foundation for subsequent actions, such as routine inspections, preventive equipment checks, and periodic assessments. By systematically identifying potential corrosion problems and implementing control measures right at the start, the program serves as a proactive strategy to minimize the risk of corrosion-related damage in the future. This initial establishment sets clear guidelines that will inform all other maintenance practices aimed at sustaining the structural and functional integrity of fleet components over time.
