The FAA Flight Standards Service (FS) is making key improvements to application processing by combining elements of the certification process.

Effective January 24, 2024, FS is utilizing a new process to increase applicant readiness for initial certifications, which is applicable to applicants for an air carrier, air operator, or air agency certificate, or the issuance of management specifications (MSpec) in accordance with Title 14 of the Code of Federal Regulations (14 CFR) parts 91 subpart K (part 91K), 125, 133, 135, 137, 141, 142, 145 (Domestic), and 147.

This new process is a continuation of our efforts to enhance the certification process.  FS is committed to designing long term, sustainable improvements that reduce certification wait times and improve application processing times. Please see FAA Notice 8900.687 for further information.
