I know all about CFI reinstatements. I did mine in October and I did it in my Mooney. Mine was expired for nine years and my material/library was from ‘89/‘90. The first thing I did was decide to be over prepared since my initial CFI was a two day affair with a discontinuance and an aircraft grounding. I took the AOPA CFI online course twice while building a completely new library, the first book I bought was the CFI practical test standards. In there is a specific list of areas to be covered during a reinstatement checkride. I then complied a complete set of lesson plans since I would be expected to teach any of the certificates and ratings I originally had, and I had everything, CFII, MEI. Then I studied for a solid month while practicing the maneuvers and ground lessons with a local, on the ball CFI. By the way, he had been teaching full time for years and was still learning stuff in helping me with my reinstatement. Finally I contacted a recommended DPE and we chatted about my background and my plan to get my CFI back. He pretty much specified what we would do during the oral exam and the flying portion. Even though my goal was to show up over prepared, the DPE found a few areas that I was weak on. The main portion of the oral exam or discussion was logbook endorsements, runway incursions, foreign student pilot training, and get this: English as a second language. Those four areas are the latest problems that Oklahoma City is having in aviation training right now, so expect focused attention there. Please feel free to contact me if you have any question.
