New spin placard, well not really new as it has been in FAR 23 for many years but only newly certified airplanes will have it. Worth noting as it emphasizes a limitation on the number of turns in a spin based on what was tested.
[(d) For acrobatic category airplanes and utility category airplanes approved for spinning, there must be a placard in clear view of the pilot--
(1) Listing the control action for recovery from spinning maneuvers; and
(2) Stating that recovery must be initiated when spiral characteristics appear, or after not more than six turns or not more than any greater number of turns for which the airplane has been certificated.]
Aerobatic category airplanes are normally tested to 6 turns and with a comprehensive spin matrix of configurations and modes so your favourite video on Youtube doesn't count for much. i.e. the recommended maximum number of turns in a spin is 6 (there are physiological effects on the pilot which also support that same limit).
