Aviation safety—the Federal Aviation Administration’s (FAA) top priority—includes oversight of commercial passenger carriers’ safety programs. According to FAA regulations, each airline must establish and maintain a safety management system—a formal, top-down focus on managing safety risks. Using this approach, FAA and air carriers identify hazards and implement corrective actions that mitigate risk. For example, air carriers must identify root causes for hazards and proactively manage risk to prevent accidents.
