My sparkplug wires did the same thing. I think it's a surface
phenomenon, based on the rubber they used in the Adel clamp. Klaus
included white rubber Adel clamps with the electronic ignition system and I wish
I'd used those everywhere.

Subject: [LML] Tygon tubing
discoloration
My
Legacy brake lines use the standard poly-flo tubing inside yellow Tygon tubing
for protection. I just noticed that the Tygon has turned black where it comes
in contact with the Adel clamps. This photo shows where the Tygon was zip-tied
to the fuel return line in the wing stub. It appears that some sort of
chemical reaction occurred with the rubber in the Adel clamp. I installed the
brake lines in 2005 (ouch!). The plane has not flown yet.
Has
anyone ever seen this before? Is it serious?
Thanks,
Adam
