EASA already requires 25 hours for the CVR for all transport class aircraft:
Under EASA’s Commission Regulation (EU) 2015/2338, aircraft with a maximum takeoff weight of 59,500 pounds manufactured after Jan. 1, 2021 must feature a CVR with a recording duration of at least 25 hours and the ability to accurately determine the location of an aircraft accident. Part of the new requirements also took effect as of Jan. 1, 2019, including the replacement of recorders featuring magnetic tape with solid-state CVRs.
