Airbus is making the Airbus 380 superjumbo model plane about 25% slower than originally planned say Airbus executives. This is partly because manufacturing is sequenced between France and Germany. The way the production system for the A380 is organized today is to split work between the French and German operations. The plane structure is built in Toulouse, France, and the cabin and interiors are fitted together in Hamburg, Germany. Tom Williams, Airbus executive vice president for programs, says this slows the completion and increases the cost. On the A330 models the work on the interior is done along the way as the structural work is being done, and this reduces cost and speeds up completion. Part of the problem is the sensitivity of the issue of moving work for unions and governments, but he now plans to push the A380 cabin outfitting back up to the earlier stage when the airplane is being built. A slower production rate means workers and engineers are learning more slowly how to build these planes efficiently by structuring tasks in a certain way and using different production methods. Boeing has also experienced similiar production delays and is working on moving up the learning curve the way EADS Airbus is doing. The A380 program has suffered delays over the years. In 2009 wiring the cabins was a problem. In 2010 a Rolls Royce engine on a A380 flight by Quantas Airways blew up on a flight after takeoff from Singapore. Because of manufacturing issues there were delays in delivery of Rolls Royce engines in 2011. Bot problems were resolved. In 2012 Airbus has found cracks in metal parts inside A380 wings which has slowed output. Airbus has delivered 77 A380 planes since 2007. The production rate is 3 A380 planes a month, compared to plans to make 4 a month by 2012. About 30 A380's are expected to be delivered in 2012, compared to 26 in 2011, 18 in 2010....
