This may sound simple to some but I think changing those faucet assemblies on the A320's proved challenging. I reckon Airbus was experimenting on a new assembly method whereby the fauctes were suspended on thin air and built the airplane around it.
Like Somefokker said?!, I must agree that the Death Cruiser 10 was Engineer friendly. The platform was smart, but you don't want to be up there when it's -30C and the wind howling like crazy.
