From: teamgrumman@AOL.COM


I'm in the process of getting an STC to repair the horizontal bracing 
using an approved metal-to-metal bonding similar to that used to make 
the part in the first place.  This wll eliminate the row of rivets down 
the side.  Plus, the fuel tank sealant currently being used is not a 
bonding agent and the rivets being used are only a fraction of the 
strength of the original bonding.

Does anyone know what the name, maunfacture, and the bonding strength 
characteristics (shear and tensile strengths) of the bonding material 
used in our planes?  A lot has happened since metal-to-metal bonding of 
our planes began.  Today, there are several approved procedures.  I 
just need to find one that meets or exceeds the original specifications.

On my tour of Chem Fab they said they used Hysol 9309 Epoxy paste 
http://www.loctite.com/int_henkel/loctite/binarydata/pdf/Hysol_EA_9309_3N
A.pdf for cold bonding to fill any after bonding voids or in areas where 
hot bonding wasn't needed or couldn't be done. I assume you are talking 
about cold bonding. From what they were saying to get any approval at 
that time for using this stuff for field repairs was almost impossible 
due to the stringent controls on preparation and proper priming of the 
surfaces. I did ask them if it was going to be possible to use it for 
bond repairs and they indicated it would most likely be included in 
Tiger's maintenance manual once they had their production certificate, 
but I never saw it produced.
