I agree whole heartedly, as would many others who operate on the AD.ENG. 4 system.
I had three Engines on the system and no problems to date. one of the engines went to nearly three times its recommended life without a problem, before I changed it out. when stripped for examination,. almost all the components were within limits. the few that weren't were non critical components and were still servicable.
