Being an old pre-AWC blade (Sans anhedral
or taper) , the main pickled titanium spar was left intact (doesn't even look that the BIM blanket was exposed or that they popped the schrader valve) and the leading edge sheath assembly (nose taco shell, heater blanket, and abrasion strip) looks to be fully intact as well.
Once the skin+core afterbody departed, theres really not much left to come apart, other than the sheath-spar bondline, which is sized pretty stoutly.
Had they flown for much longer I am quite sure they would have lost the Sikorsky (patented) removable blade tip assembly as those fasteners are already a fatigue issue.
