It is critical to understand that the type of damage that is essential to address in a metal prop because of the risk of the damage acting as stress riser and starting a fatigue crack is not going to be as critical on the protective strip on the leading edge of am MT prop.

As said above these blades don't have a life and the only place in Europe that you can get new leading edges fitted is the factory, perhaps being so far from the factory a Southern Hemisphere repair facility is needed.
