I called the examiner who I took my CFI ride with and asked him if the ride reset the BFR clock and he said yes. His reason was because of the wording in the CFI PTS which says that the applicant must "demonstrate" not just "instruct" the required maneuvers to commercial standards. After we talked I emailed him the FAA letter that was posted a few posts earlier and he called me and recommended that I stop by and get the endorsement so make sure all is good. Glad I read this thread and thanks for the letter. This issue needs to be clarified in the regs...
