DEPARTMENT OF TRANSPORTATION

Federal Aviation Administration


Metallic Materials Properties Development and Standardization 
(MMPDS) Handbook

AGENCY: Federal Aviation Administration (DOT).

ACTION:  Notice of availability and request for public comment; 
correction.

-----------------------------------------------------------------------

SUMMARY: This notice corrects the ``How To Obtain Copies'' Web address 
published April 11, 2005 (70 FR 18452) that announced the availability 
of and requested comments for a proposed plan to manage the Metallic 
Materials Properties Development and Standardization (MMPDS) Handbook 
which has replaced the now cancelled ``Department of Defense Handbook: 
Metallic Materials and Elements for Aerospace Vehicle Structures,'' 
(MIL-HDBK-5) and our intention to make the MMPDS Handbook the primary 
source of metallic materials and fastener allowable properties 
demonstrated to comply with FAA airworthiness requirements.

DATES: The comment period is extended to July 5, 2005.

ADDRESSES: Send all comments on the proposals to: John J. Petrakis, 
National Aging Aircraft Program Manager, Technical Program & Continued 
Airworthiness Branch, AIR-120, 800 Independence Ave., SW., Washington, 
DC 20591; telephone (202) 267-9274; fax (202) 267-5340. You may deliver 
comments to: Federal Aviation Administration, Room 815, 800 
Independence Avenue, SW., Washington, DC 20591, or electronically 
submit comments to the following Internet address e-mail [email protected]. Include in the subject line of your 
message the title of the document on which you are commenting.

FOR FURTHER INFORMATION CONTACT: Mr. John J. Petrakis, AIR-120, Room

Background

    Though now cancelled, ``Metallic Materials and Elements for 
Aerospace Vehicle Structures'' (MIL-HDBK-5) continues to be used as a 
primary source of statistically based design allowables for metallic 
materials and fastened joints used in the U.S. military and commercial 
aerospace design. As such, the handbook was kept current for almost 50 
years by joint government and industry effort.
    In 1997, the Air Force began to shift from military to commercial 
specifications which forced the aviation industry to find an 
alternative approach to sustain MIL-HDBK-5. Because MIL-HDBK-5 remains 
critical to commercial aircraft certification and the maintenance and 
continued airworthiness of the commercial fleet, the FAA has assumed 
responsibility for the management of this essential reference document.
    In support of aircraft certification, the FAA intends to make the 
MMPDS Handbook the primary source of metallic materials and fastener 
allowable properties demonstrated to comply with FAA airworthiness 
requirements.
    In addition, the FAA is proposing a plan to sustain the Handbook 
and secure funding for maintaining MMPDS from multiple sources, 
including other government agencies, industry stakeholders, the private 
sector, and from sales of the handbook and related products.
