Tapping a composite rotorblade for voids 

I have a coin also, I use it if I have a questionable spot.

@@TractorMan104 I worked for Australia's biggest airline and they literally spent 20 cents on our tappers...if you get my drift. 😀

@Daniel Capers thanks for the feedback . For me it's better to limited the surface before we do the tape test in order to ensure that we don't forget some surface.

Sometimes you have to throw away the whole part.

If the void is small enough and depending the location no repair is needed. If it is along the edge we do an injection repair. Raise the edge and inject adhesive.
