1. You must be
   • at least 18 years old;
   • able to read, write, and understand English.

    

2. You must get 18 months of practical experience with either power plants or airframes, or 30 months of practical experience working on both at the same time. As an alternative to this experience requirement, you can graduate from an FAA-Approved Aviation Maintenance Technician School.
   
    
3. You must pass a written examination, an oral test, and a practical test for both power plants and airframes within any 24 month period.

You must meet all the requirements listed above for United States citizens. You must also meet the following requirements:

1. Demonstrate you need a mechanic certificate to maintain U.S.-registered civil aircraft and you are neither a U.S. citizen nor a resident alien.

3. Provide a detailed statement from your employer saying what specific types of maintenance you preformed on each aircraft, and how long you performed it.

The FAA may waive the language requirement if you live outside the United States. They would stamp your certificate "Valid only outside of the U.S."

Do I need any other certificate to work on avionics equipment?

If you have an airframe certificate you don't need any other certificate, but you must be properly trained and qualified and have the proper tools and equipment. You can even work on avionics equipment without a certificate if you have avionics repair experience from the military or from working for avionics manufacturers and related industries.
