For minimum costs with the manufacturing preparation necessary to make a single airplane, an adjustable jig was designed that will be used to assemble: the horizontal stabilizer, elevator, horizontal stabilizer, rudder, left/right aileron, and left/right flaps. It is under construction, design is not finished yet for some of them. The design started from an existing jig which is not used any more and will be modified according to the new requirements.
What you see in the pictures was made in the 3DEXPERIENCE platform, CATIA Assembly Design, Part Design, and ENOVIA Design Review apps.
