The Federal Aviation Administration (FAA) Part 121 air carrier certification is a rigorous process designed to ensure that applicants possess the capability to design, document, implement, and audit safety-critical processes. This certification serves two primary objectives:
At its core, the certification process evaluates whether an applicant can conduct operations in compliance with all relevant regulations while effectively managing risks in their operational systems. The FAA maintains a strict stance: applicants unwilling or unable to meet these standards will be denied certification.
The FAA certification process, as outlined in Order 8900.1, involves a pre-application phase followed by five distinct stages and three critical gates that must be successfully navigated.
The initial phase focuses on information collection and emphasizes the importance of implementing a Safety Management System (SMS). This foundational step sets the stage for the subsequent certification stages.
Title 49 of the U.S. Code clearly establishes safety as both the primary responsibility and legal obligation of certificate holders. The FAA's role is to ensure applicants fully understand and accept this responsibility before certification is granted. Key legal authorities include:
The FAA employs a system safety-based certification process, evaluating applicant documentation through this lens. The Safety Assurance System (SAS) serves as the FAA's framework for verifying compliance with regulations and safety standards while assessing an applicant's ability to manage system-related risks.
FAA's Role:
Applicant's Role:
No. SAS represents an FAA oversight methodology for certification and supervision, not a set of standards carriers must meet.
14 CFR Part 5 mandates that certificate holders under Part 119 maintain a safety management system that meets Part 5 requirements.
