The Metallic Materials Properties Development and Standardization handbook, and its predecessor MIL-HDBK-5, are the preeminent sources for aerospace component design allowables. It is an accepted source for metallic material and fastener system specifications for the FAA, DoD, and NASA. It contains design information on the strength properties of metallic materials and elements for aircraft and aerospace vehicles. The MMPDS replaces the prior editions of the MMPDS as well as all editions of MIL-HDBK-5.
