Organfreak. TKT = Teflon/Kapton/Teflon (that's a much safer aromatic polyimide wiring insulation). That was the smart Airbus move.
Most of the Kapton is now in the boneyards in a vast array of military aircraft and airliners. In most cases, it was predominantly the Kapton that put them there. In many cases, because of the expensive innards (such as in P-3 Orions and S-3 Vikings) it was always cheaper to rewire at a major scheduled refit.
