Usually, Boeing send the aircraft straight from final assembly to the paint hangar with perhaps a couple of days outside. With the current situation, Boeing is now sending airplanes directly to the EMC to finish assembly activities before they are painted.
Using my data along with Matt Cawby's Tweets of 787 movements out of the paint hangar, I was able to get an idea of time from roll out from final assembly through painting. Matt Cawby has been tweeting when 787s exit final assembly as well as when they come out of the paint hangar. For the last few 787s I've created a table that explores the additional time that is needed to finish these aircraft. I am assuming that when the aircraft is transferred from the EMC (Everett Modification Center) to the flightline or the paint hangar, that it is completed all necessary travelled work and is now resuming the normal production sequence to prepare it for first flight and eventual delivery to the customer.
According to the data, the average time between roll out of the aircraft fro final assembly to the time it is taken out of the paint hangar or is observed on the flightline is about 15 days. Painting itself would take anywhere from 4 to 7 days depending on the complexity of the scheme being applied and the customer's satisfaction with the paint job.
Using these assumptions along with observed data, it is reasonable to assume that the aircraft spends anywhere from 10 to 12 days at the EMC to finish off the traveled work resulting from the problems at Charleston. I do expect that this should go down as the number of contracted workers increase and reduce the number of jobs over the next few months.
The most interesting question is will Boeing need to hire these contracted employees on a permanent basis in South Carolina in order to stay at rate (not to mention to assist when they increase to 12 and eventually 14 aircraft per month)? If so, one has to wonder what this would cost Boeing and the 787 program in terms of profitability.
