No idea how the stats stand, but I also get the impression that people think the T67 is problematic in spins because it's a popular aircraft for FTOs to do the compulsory spinning bits of ratings, particularly FI's. E.g. a couple of instructors were killed near Oxford doing just that. The problem is, this skews the perception of how dangerous they are, since these people are not in current practice for spinning, for the most part. So they make the headlines disproportionately often.
It's a theory...
