For nearly six decades, the FAA has required all air carriers to conduct continuous evaluations of their maintenance programs. Specifically, regulations require air carriers and commercial operators—both Part 121 and 135 (for aircraft with more than 10 passenger seats)—to establish a continuing analysis and surveillance system (CASS) to monitor, analyze, and optimize the performance and effectiveness of their maintenance and inspection programs.

The regulations (CFR 14 121.373 and 135.431) that define CASS are performance-based. According to FAA AC 120-79A, a performance-based regulation is a regulatory approach that focuses on measurable outcomes, rather than prescriptive processes, techniques, or procedures. This perspective leads to defined results without a specific direction or instruction in the regulation regarding how to obtain those results.
