My understanding as explained by a friend/A&P/IA/Part137 guy who is working
with MT to apply one of their models to PT6 driven AirTractors is that the
interior hub and bearing work is fairly normal however after the blades are
ground they are built back up and finished to original factory specs.

People are claiming 3-5 knots extra on the new prop but the
interesting thing about the new prop is that it (in theory) has an
unlimited life span. During overhaul the blades do not get smaller as
metal blades do so you can overhaul it as many times as necessary.

What's involved with overhauling a composite prop?
