Re: Brantly Issues New Service Bulletin

Hi Bryan....I know that you "get it". I can tell by your posts. I just wanted to steer the discussions towards a positive attitude of attempting to obtain results. Hopefully those who read my comments will understand that. re: the mods to existing blades......seems like we could get hold of a "bad" blade, caused to be rated as unusable by the sb111, and dissect it, step by photographed step, and with certifiable documentation by an authoratative person with roots in the aviation engineering community. I am of the opinion that would provide a definable "position" that could be taken by Brantly owners regarding the validity of the issuance of the sb111. We might find that the sb indeed has value for us all if we open up a couple of rejected blades and they are all truly compromised. In fact, perhaps the question should be asked of the FAA, and even Mr Hardman, how many "bad" blades were discovered during the compilation of facts that caused the service bulletin. So many questions......so little time.
(and I wonder how many of our readers know what a spoke shave really is? ha! The old Bell 47 blades were made out of wood, weren't they? your idea might actually have some merit! ) although.... "tongue in cheek" quickly comes to mind.
There is a tape advertised for use with Robinson blades that helps to prevent delamination.....something like that might very well add strength to the blade if applied long the leading edge. How much?....who knows that answer? the problem with all of this is that one has to literally be an aeronautical engineer to analyze/examine/determine/report, etc. upon anything like that. or have the time and money to experiment. Anyway, think I'll step back and draft some reading for the FAA and Mr. Hardman. take care.
