How do I get an FAA airframe and powerplant license with foreign experience?
If you are in the U.S. at the time you apply, you will need a letter from your country’s Civil Aviation Authority attesting that your training and experience level meets the U.S. requirements.
If you are not in the U.S. at the time you apply, you must show proof that you need the certificate to maintain U.S.- registered aircraft. Procedures for providing proof are located in FAA Order 8900.1, Flight Standards Information Management System, Volume 5, Chapter 5, Section 3, Certificate Foreign Applicants Located Outside the United States for Title 14 CFR Part 65, Mechanic Certificate Rating.
