"The final rule amends the existing Part 107 in Title 14 of the Code of Federal Regulations. The rule has been sent to the Office of the Federal Register and will become effective 60 days after the publication date in the Federal Register.
Publication is expected in January 2021." If you look at the copy of the Final Rule itself, you will see "Effective dates: Except for subpart C of part 89, this rule is effective [INSERT DATE 60 DAYS AFTER DATE OF PUBLICATION IN THE FEDERAL REGISTER]. Subpart C of part 89 is effective INSERT DATE 60 DAYS AND 18 MONTHS AFTER DATE OF PUBLICATION IN THE FEDERAL REGISTER]." I was surprised how fast this can occur.

Not
just a guess on my part - the FAA will notify certificate/endorsement holders of the compliance dates for the changes to Part 107 once the date has been established following publication. I believe they use the same address you established in IACRA. My last recurrent exam, I towed my RV to a park near the test site and slept there the night before the exam - it was that far away... Not gonna miss that hassle the way I missed my $150 every two years. Way to go FAA!
