57-10-51 Inboard Diagonal Strut Fitting Construction
In this posting here were just going to go through the process of manufacturing 57-10-51 inboard diagonal strut fitting.

This is just kind of an inside look into what takes place during the manufacturing process of some of the components on the aircraft.

The drawings on the builder database are PDF files that are used both by the builders or the assemblers of the aircraft as well as during the part manufacturing process.

The PDF file gives and in context orientation of the part for the overview of where the part is used As well as a detailed three view drawing for manufacturing purposes.

Once again we remind you every time we post something on one of these postings that the drawings are only updated on the builder database and not on these postings.
