May 20, 2015, c. Leeham Co. The 27th Airbus A350 has started its journey in the Final Assembly Line (FAL) in Toulouse and one can do a first analysis of how the initial batch of A350s has fared on the final production line. For this purpose, we have been closely monitoring the through-flow times for each of the nine steps that constitute the final assembly of the A350.
Initial serial production was done without a dedicated station for post certification rework. This was introduced from the third production aircraft as station L70.
From initially spending up to four months in this station, the rework situation has improved fast.
FAL production times are now stabilizing and when rework is no longer needed the profile of a learning curve can be seen.
