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) Start Printed Page 18453continues 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.
