CFI renewal records
All I ever did was, per the FARs, was keep a record of the students I sent up for practicals and the results of their tests in the back of my logbooks. Most of mine were 141 self-examining stage checks, but I tracked them just the same as if they were regular Part 61 flight tests.
I brought my logbooks and a typed 8710 to the FSDO, stated to the person at the counter that I wanted to renew based on activity, and walked out with a fresh temporary. For the most part, just as easy as that.
Perhaps I should qualify what I just wrote by saying that was my experience at the SDL FSDO eleven years ago. FSDOs may be more anal now.
