Following delivery last week of the first 787-9 rudder built in China by Chengdu Civil Aviation (CCAC), Boeing extended its supply chain further for yet another airfoil subassembly, choosing the UK’s GKN Aerospace to build the winglet for the 737 Max. GKN joins Korean Air Aerospace Division (KAL-ASD) in South Korea as co-supplier of the raked, dual-feather-design winglet.
