Changes to Application for Certification Process

This action announces the implementation of an update to the process for an applicant to withdraw, or for the FAA to deny, an application for certification to better address the expectations of applicants and the FAA with respect to certification timelines. The change supports the FAA's mission and the Certification Services Oversight Process (CSOP) by enhancing engagement with air carrier, air operator, or air agency certification applicants and further streamlining the certification process. This update is intended to reduce wait times and better utilize FAA resources for processing complete applications from prepared applicants, thus increasing efficiency in accomplishing the certification process.
