FOREWORD

The Metallic Materials Properties Development and Standardization (MMPDS) Handbook, is an accepted source for metallic material and fastener system allowables for the Federal Aviation Administration (FAA), all Departments and Agencies of the Department of Defense (DoD), and the National Aeronautics and Space Administration (NASA). Per guidance provided by FAA Advisory Circular (AC) 25.613-1 and FAA policy memorandum PS-AIR100-2006-MMPDS, the A and B values contained in the MMPDS have been determined to satisfy the regulatory requirements defined in Title 14 of the Code of Federal Regulations (CFR) 27.613(d), 29.613(d), 25.613(b) and 23.613(b).

MMPDS-04 is the replacement to MMPDS-03 and prior editions as well as the replacement for all editions of MIL-HDBK-5, Metallic Materials and Elements for Aerospace Vehicle Structures Handbook that was maintained by the U.S. Air Force. The last edition, MIL-HDBK-5J, was classified as noncurrent in the Spring of 2004.

This document contains design information on the strength properties of metallic materials and elements for aircraft and aerospace vehicle structures. All information and data contained in this Handbook has been reviewed and approved in a standardized development process. The development and ongoing maintenance process involves certifying agencies, including the FAA, DoD, and NASA, and major material suppliers and material users worldwide. The data and procedures in this Handbook are continuously reviewed, and if needed, are modified or removed for consistency. With advances in materials and fastener systems, and with the review process of existing information, annual updates of the MMPDS are expected. As such, it is recommended that the latest version of the MMPDS be used.

Beneficial comments (recommendations, additions, deletions) and any pertinent data that may be of use in improving this document should be addressed to Secretariat, MMPDS Coordination Activity (614- 424-4433 voice or bcommpds@battelle.org email), Battelle, Mechanical Analysis Group, Room 11-1-080, 505 King Avenue, Columbus, OH 43201.

This Handbook has been approved for public release with unlimited distribution.
