tinyclark Posted August 8, 2014 Share Posted August 8, 2014 If you are talking about the outer wing break panel, we had quite a few problems with those over the years, but many times it was the lower connectors. However, I think you get monsoon rains over there that we rarely see. Attached is guide to system wiring I did many years ago. There are procedures in T.O. 1-1A-14 that deal with sealing, in chapter 025 00. Most of it deals with silicone or urethane tapes wrapped around the connectors. You could use Silicone or any other approved sealant on the top of and around the sides the connectors. Since these large connectors usually don't get disconnected, you could be very liberal with the sealant, but leave the bottom part unsealed to allow any moisture that might get in to drain out. The USAF has begun replacing all of those connectors during depot maintenance. Quote Link to comment Share on other sites More sharing options...

tinyclark Posted August 8, 2014 Share Posted August 8, 2014 I think this was a TCTO to be done during depot maintenance. I have been retired for 3 1/2 years so I am not exactly sure of the status. I don't know if it is being done at overseas depot locations or on any foreign military service aircraft, since the USAF is paying for it. They will be replaced only one time, this is not part of any scheduled depot work. Quote Link to comment Share on other sites More sharing options...
