What must the holder of an expired CFI certificate do to receive a new certificate?

To receive a new Certified Flight Instructor (CFI) certificate after it has expired, passing the appropriate practical test is essential. This practical test is a demonstration of the instructor's flying skills and knowledge of the instructional process. The Federal Aviation Administration (FAA) requires this test to ensure that the instructor maintains proficiency and is capable of safely and effectively teaching flight operations. This assessment covers various maneuvers, emergency procedures, and the ability to instruct a student in a flight setting.

While there are other steps involved in the certification process, such as completing training requirements and possibly attending courses, the key factor that reinstates an expired CFI certificate is the successful completion of the practical test. This ensures that the instructor is still up to date on current practices and safety standards essential for teaching flight to students.
