Foreign Aircraft Operations in Mexico: Understanding Mexico's Documentation Review Process
A developing documentation review process is affecting foreign aircraft operations in Mexico. While no official publication formally establishing this process has been published, operators have been asked to submit extensive documentation packages for review prior to flight authorization.
While existing authorization processes remain in place, operational experience suggests that some operators may now be subject to an additional documentation review prior to flight authorization.
Based on local communications outlining a process requiring operators to submit a complete documentation package in a specific format for AFAC Central review, the level of detail provided offers valuable insight into the information currently being requested.
What Documentation Is Being Requested?
Based on documentation reviewed and operational experience, the package may include some or all of the following items, depending on the type of operation:
Formal request letter addressed to AFAC.
Single Entry Authorization (AIU).
AIU payment receipt.
Foreign Air Operator Certificate (AOC), if applicable.
Operations Specifications (OpSpecs), if applicable.
Part 135 authorization, if applicable.
Aircraft Registration.
Airworthiness Certificate.
Valid insurance policy with Mexico coverage.
AFAC Insurance Validation (for operators with a validated AOC)
Pilot licenses and valid medical certificates for the PIC and SIC, if applicable.
LOPA/Cabin Layout.
Passenger and crew manifest.
Departure Flight Plan.
Operational Flight Plan (OFP) or flight package.
The submission process itself appears to be highly standardized.
Documentation is submitted to AFAC Central for review through coordinacion.safety@afac.gob.mx.
Depending on the location, local AFAC authorities may also request to be copied on the submission as part of the coordination process.
The process specifies that all documentation should be consolidated into a single PDF file and submitted using a standardized naming convention. The email subject line is also expected to follow a predefined format.
File Name Format: REGISTRATION_COMPANY_ROUTE_DATE
Example: N22MX_ADAMS-AVIATION_MMTC-MMJC_04MAY2026.pdf
Email Subject Format: DATE / REGISTRATION / COMPANY / ROUTE / REGION
Example: 04-05-2026 / N920PT / TVPX AIRCRAFT SOLUTIONS / MMTC-MMMZ / REGION II
The level of standardization involved suggests a structured review process rather than isolated documentation requests.
Who Does the Process Apply To?
Operational experience suggests that implementation does not currently appear to be consistent; in some cases, authorities have indicated that the review primarily applies to U.S.-registered aircraft. However, documentation requests have also been observed involving non-U.S.-registered aircraft conducting international operations.
As a result, operators should avoid assuming that the process applies exclusively to N-registered aircraft or that procedures observed at one location will necessarily apply at another.
Operational Impact: Why This Matters Beyond Documentation
While the documentation requirements themselves may appear manageable, the potential operational impact deserves careful consideration.
Operational experience has shown that delays may occur while awaiting AFAC Central review and confirmation. In some cases, delays of up to two hours have been observed before final authorization was received.
Although these delays may seem minor, they can affect multiple aspects of the operation.
One example involves U.S. Customs and Border Protection (CBP) Permission to Land approvals. Depending on the airport of entry, many CBP offices authorize arrivals within a specific time window, often limited to approximately
+/- 30 minutes from the approved arrival time.
Depending on the CBP port of entry, significant departure delays may require operators to update arrival information, coordinate revised arrival times, or communicate directly with the port of entry.
Beyond CBP considerations, departure delays may also affect:
Airport slots and arrival approvals.
Ground transportation schedules.
Passenger itineraries.
Handling and support services at destination airports.
These considerations become increasingly important as Mexico prepares for elevated levels of international aviation activity associated with the World Cup.
During high-demand periods, even short delays can have a greater operational impact due to increased traffic and additional coordination requirements.
For this reason, operators should view the documentation review process not simply as an administrative requirement, but as a planning factor that may influence the overall timing of an operation.
What Operators Should Do
Operators planning flights to Mexico should consider the following best practices:
Build additional flexibility into flight schedules.
Coordinate closely with your Handling company to identify documentation requirements before departure.
In the case of flights to the United States, review CBP Permission to Land timing limitations and establish alternate plans in the event of delays.
Avoid assuming that procedures applied at one airport will necessarily be applied at another in the same way.
Looking Ahead
At this stage, the industry's greatest challenge may not be the documentation itself, but the apparent lack of a fully standardized implementation process.
The information currently available suggests that AFAC Central is increasing its review of certain foreign aircraft operations, but questions remain regarding applicability, timelines, and long-term implementation.
As implementation continues to evolve, CST Flight Services remains actively engaged in supporting operators through direct operational coordination, regulatory monitoring, and real-time guidance. By combining local expertise with day-to-day operational experience, CST Flight Services helps operators anticipate challenges, adapt to changing requirements, and maintain operational continuity throughout Mexico.
During periods of increased traffic and heightened operational complexity, informed planning and experienced support can often make the difference between a smooth operation and an avoidable delay.
