First locate your nearest FSDO at http://www.faa.gov/about/office_org/field_offices/fsdo/ then make an appointment to meet with an Airman Inspector prior to your CFI certificate expiration date. The wait time for an appointment can be several weeks depending on the FSDO. Ask if you should bring a paper 8710 application or if they want you to apply through IACRA. Lastly, bring the following: a. Your signed Graduation Certificate (date of issuance must fall within three calendar months prior to CFI certificate expiration date) b. Your completed and signed 8710-1 (if they accept paper applications) c. Your valid US Driver’s License, Passport or Military ID d. Your unexpired Flight Instructor Certificate (hard copy).
