NWS, a worthwhile point re the external load operations impact on CRT’s ( Component Replacement Time ). SA’s eyes were opened after the S-64 started logging ( and the 61 as well ). Drive train cycle frequency went way up and naturally the fatigue spectrum compared to the spectrum used with the US Army was very, very different. I don’t know this with certitude, but that may have been a factor in selling the type certificate to Erickson i.e., the inability to get a handle on the real usage in the field when logging. Erickson is a sharp outfit-curious as to how they approach the issue.
