14 CFR Part 135 Certification Process

ANNOUNCEMENT

Beginning on September 30, 2026, the Part 135 Air Carrier/Operator Certification Application process is transitioning to Aviation Integrated Safety (AIS) Services.

Applicants can complete certain certification activities on the updated system, replacing the legacy Safety Assurance System (SAS). During this transition, some FAA resources may still reference SAS as content is updated to reflect the new process.

Visit AIS Services to submit a Part 135 application.


The certification process utilizes a phase and gate system that has 5 distinct phases and 3 gates. All items in a phase must be successfully completed prior to continuing past a gate and into the next phase of the process. An applicant will not be certificated until the FAA is confident that the prospective certificate holder is capable of fulfilling the required responsibilities and will comply with 14 CFR in an appropriate and continuing manner.

Below is a brief overview of the Phases of Certification with a link provided for more detailed information on each phase. Applicants should review the information contained in the provided links, as well as any additional links contained within.
