Metallic Materials Properties Development and Standardization 
(MMPDS) Handbook

AGENCY: Federal Aviation Administration (DOT).

ACTION: Notice of availability and request for public comment.

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

SUMMARY: This notice announces the availability of and request comments 
on the proposed Metallic Materials Properties Development and 
Standardization (MMPDS) Handbook to be used as the primary source of 
metallic properties for compliance. This proposed handbook will replace 
the now cancelled ``Department of Defense Handbook: Metallic Materials 
and Elements for Aerospace Vehicle Structures,'' (MIL-HDBK-5).

DATES: Submit comments on or before June 20, 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 
815, Federal Aviation Administration, Aircraft Certification Service, 
Aircraft Engineering Division, 800 Independence Avenue, SW., 
Washington, DC 20591, Telephone (202) 267-9274, FAX: (202) 267-5340.

SUPPLEMENTARY INFORMATION: 

Comments Invited

    You are invited to comment on the proposed Handbook identified in 
this notice by submitting written data, views, or arguments to the 
address listed above. You may examine all comments revised on the 
proposed Handbook before and after the comment closing date at the 
Federal Aviation Administration, Room 815, 800 Independence Avenue, 
SW., Washington, DC 20591, weekdays except Federal holidays, between 
8:30 a.m. and 4:30 p.m. The Director of the Aircraft Certification 
Service will consider all communications received on or before the 
closing date before issuing the final Handbook.

Background

    Though now cancelled, ``Metallic Materials and Elements for 
Aerospace Vehicle Structures'' (MIL-HDBK-5)

[[Page 18453]]

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.
    The FAA acknowledges the value of MIL-HDBK-5, and now the MMPDS, to 
commercial aircraft certification and maintenance of the commercial 
fleet. However, as such, the FAA's current budget constraints make 
continued funding of MMPDS uncertain.

How To Obtain Copies

    You may get a copy of the proposed Handbook from the Internet at: 
http://www.faa.gov/certification/aircraft/DraftDoc/CommNotice.htm. You 
may also request a copy from Mr. John J. Petrakis. See the section 
entitled ``FOR FURTHER INFORMATION CONTACT'' for the complete address.

    Issued in Washington, DC, on March 31, 2005.

Assistant Manager, Aircraft Engineering Division, Aircraft 
Certification Service.
