This dataverse contains the configuration controlled documentation for the SOFIA Telescope Assembly subsystem 4000 Flange Assembly (FA): The Flange Assembly (the mechanical interface to all science instruments) comprises the Instrument Flange and the Pressure Window Subassemblies as well as the Balancing Subassembly and the Cable Load Alleviator.

The SOFIA TA Technology and Operations Archive Manual contains a guide how to use the archive as well as an overview of the SOFIA TA Hardware Breakdown Structure (HBS).

The FA component is organized according to the HBS and contains subsystems as listed in the following tree structure:
