With Boeing's North Charleston plant building a 787 once every month, there is an expectation that we would be seeing more airplanes on the ramp at Charleston. However it has been more than a month since Boeing rolled out an airplane from building 88-03.
The planes being worked on (currently) at this plant are earmarked for Air India and two of the three Chinese customers (Hainan and China Southern). Given the issues surrounding these customers, it is not anticipated that deliveries will be made anytime soon or if they are delivered, it would be a glacially slow pace. 787 assembly at Charleston is completed in four position, just like the 787 line in Everett. It is my belief that Boeing is going to take its time rolling these airplanes out of the Charleston factory and will use the extra positions within the assembly hall to store a couple of airplanes. There are 8 flightline spots at Charleston so there isn't a lack of room. The only reason to keep them inside to to ensure all assembly tasks are completed and to protect the airplanes from the elements.
I've listed LN 76 as stored but its location is inside building 88-03 in Charleston.
