Manufacturer Design & Engineering Standards

A curated library of rare, original engineering and manufacturing normative documents issued by the world's leading aircraft manufacturers. These are not aircraft-specific manuals — they are the cross-fleet design and production standards that governed how entire families of aircraft were engineered, built, tested, and maintained.

This collection spans manufacturers from Germany, the United States, the United Kingdom, the Soviet Union, Italy, Japan, and beyond — covering the full arc of aviation's golden age from the 1930s through the Cold War era.
