I am writing a study for college on Aircraft parts and I am covering bonding leads. It says bonding leads are available to: AGS, LN, CSP, JN -- what are these? are they abbreviations? Also.... Seals in the CSP, AS, SP, PAN, MBB, VFN, JN, BS range ---- what are these abbreviations? Any help would really help me, I'm clueless! Thanks
