Interesting! - There are two posts earlier in this thread (original post and (I presume) 4th post in the thread) from folk saying they have one on their T-67, and our CAMO has confirmed it is approved if we want to change.

Thanks to everyone for their comments. I have been in touch with MT-Propellers today, they confirm that the Supplemental Type Certificate 10070096 has been issued by EASA for T67M and T67M-MKII Firefly. A copy of the STC is suppled with the prop on delivery.
