If that is the blade that caused the crash, the fracture point is not at the suspect stress riser location. Does that mean the whole blade is prone to stress cracks across the chord? Or is that even the correct blade? Or was there another cause entirely?
I'm not feeling super duper flying around on my -7 blades these days. Even after I get them back from the body shop with their precision stress riser elimination operation performed by Bud, the best bondo man in the county.
