Actually their was an AD issued for the tail incident, but only for AA1x’s and the AA5 Traveler. AD 2021-14-12, referencing SB 195A. It only applies to part B of the SB not part A. The FAA issued a NPRM in December of 2021 for part A of SB 195A which would have included the AA5, AA5A and AA5B but this was withdrawn by the FAA in April 2022 after efforts by GOPA, AOPA and others convinced them it was unnecessary.
