What a joke! If there is a problem with the blades filing off an edge will not do it. Related to this and there is a lot of debate, what is the impact of the SB on a PT91 operator, does it have to be compiled with by the time stated or not? There seems to be a lot of debate on when or if a SB
has to be compiled with? I would definitely not want to be the first one in the shop for this "fix".
