The pneumatic system in the hangar had problems with one of the retractitle hose hanging from the ceiling. The hose did not get tangle up again so we fixed it reassembling the entire mechanism and tighting the inside spring to add extra tension. Wealsoi updatedtra the Rack E wrapping with paper the tables where the empennage skins lay on.
TIP: Be careful before assembling again, so you do not miss the direction in which the hose will tangle.
