Final rule.

This final rule replaces Special Federal Aviation Regulation 100 (SFAR 100). SFAR 100 allowed Flight Standards District Offices (FSDO) to accept expired flight instructor certificates, expired inspection authorizations for renewals, and expired airman written test reports for certain practical tests from U.S. military and civilian personnel (U.S. personnel) who are assigned outside the United States in support of U.S. Armed Forces operations. This action is necessary to avoid penalizing these U.S. personnel who are unable to meet the regulatory time limits of their flight instructor certificate, inspection authorization, or airman written test report because they are serving outside the United States. The effect of this action is to give these U.S. personnel extra time to meet the eligibility requirements under the current rules.
