I did a little search for 8410 on faa.gov and found a couple .pdf files. I believe form 8410 is for a proficiency check. According to 61.56(d), a pilot who has, within 24 months, passed a pilot proficiency check need not accomplish the flight review. It appears that this would satisfy the BFR requirements.
This is all from some quick research, don't quote me.
Hey Eagle - yes I believe an 8410 prof check counts as a BFR. Call a Flight Safety center and ask them but I'm sure that's correct. I've been flying for a little over 10 years and have NEVER done a BFR. It's always been either a new license. type rating, or 135/121 prof check.
