One of these bellcranks was just recently found cracked in my local area. Visible (red) dye penetrant inspection may well reveal a crack but will not guarantee that there is no crack. Fluorescent dye penetrant inspection (FLPI) is far better but is still subject to factors that could hide a very small crack. Assuming that there is reasonabe access the best inspection method is Eddy Current. This could possibly be done without removing the balance arm. I would suggest you contact a reputable NDT company in your area for advice.

I expect I need to pull the balance weight to dye pen the bracket attachment? ========== rget="_blank">http://www.matronics.com/Navigator?Yak-List ========== http://forums.matronics.com ========== le, List Admin. ="_blank">http://www.matronics.com/contribution ========== ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message yak-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Yak-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/yak-list Browse Digests http://www.matronics.com/digest/yak-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
