[C320-list] Leak at Propeller Shaft Strut

[Dennis Harris]

Thanks for your reply.  I don't have a blister problem now, and didn't want 
to create one with this repair.  Therefore, my preventive effort will be 
local to the repair area.  It has been recommended to me that if we use 
epoxy to fill and repair the ground away area that we will be protected 
against future blisters.  That's likely the way that I will go.
