I have to remove the bearings for inspection. Some are really stuck with primer others almost fall out. I was smart enough to ring out the replacement heater mat before bonding it on. That would have sucked if it was bad! KevinTWe always just used a lot of tape to hold them to the tail paddles while the adhesive cured. Our main rotor blades rarely had the abrasion strip fail.
Gah I so hated changing the elastomeric bearings on the tail paddles. I could always find some electronic gripe to work on when that job popped up!
Well this one is owned and operated by a friendly country in the "gulf" region and I doubt it gets used at all. However we can't send it back not working. From personal experience it does get cold enough there to need it. KevinTWe never actually used the anti-ice system except for one time. Usually the harness was removed from the main rotor head and the plugs were cut off the tail rotor.
But like I said we used the de-ice system once when we were doing a North Star in the North Atlantic in January. It looked like a lightning show when they flipped the switch on deck! They quickly shut down and we had to change 3 blades and both tail paddles.
