Hello
I am working on understanding why The Hamilton Standard 54H60 blades used on the C-130's and the P-3 have been cracking . An example would be the 10 July 2017 KC-130 mishap in Mississippi as well as others. Usually it not the gears, but than it does happen. But i am interested in any info regarding any incidents that you all may recall of a blade separating from an aircraft. I am a NDT Specialist looking into where,when and how this happens and and information you may have could be very helpful in my research.
Thank you for your time.
