I read that the engine nacelles are 3 inches larger than the current ones and due to this they have to redesign the nose and main gear. There is a suggestion that the lengthened nose gear - which will not fit into the fuselage - and the main gear struts should compress hydralically as they are retracted and expanding hydraulically as they are lowered. This will give the necessary clearance for landing. I can imagine something going wrong and all three wheels stuck in their wells!
