Brief Description: Attach FWD Center Section to FWD Fuselage Ribs
There was some curve in the bottom skin making it difficult to get proper alignment of the unsupported fuselage bulkheads. The mis-alignment was obvious when looking at the seat rail supports as they were not parallel with the F-1048 ribs and F-1043C attach angles. The F-1043D-L cover was installed in order help alignment while the F-1043A FWD fuselage bulkheads were riveted to F-1043C attach angles.
