On May 30, 1991, the FAA issued AD 91-08-51, amendment 39-7031 (56 FR 26610, June 10, 1991) (originally issued on April 5, 1991, as telegraphic AD T91-08-51). That AD applies to certain
McDonnell Douglas Model MD-11 airplanes, and Boeing Model 747-400, 757, and 767 series airplanes. That AD requires a revision to the FAA-approved Airplane Flight Manual (AFM) and installation of a placard to
prohibit the use of Nondirectional Beacon (NDB) approaches for landing. That action was prompted by an anomaly in the Honeywell Flight Management System (FMS) one million word (1M or 700K) data bases (9104 cycle or earlier). The actions required by that AD are intended to prevent an airplane deviating from the published approach to the
runway, which could lead to premature ground contact before reaching the runway.
Actions Since Previous AD Was Issued
In February 2004, the FAA Office of Rulemaking (ARM-20) asked the public to tell us which regulations we should amend, eliminate, or simplify. We received about 100 comments from more than 30 commenters. One of the comments was on AD 91-08-51. The commenter stated that the navigational databases are upgraded monthly and no flight crew will be using a 13-year-old navigational database today.
We agree with the commenter that AD 91-08-51 is no longer necessary and therefore we will rescind the AD. We have received confirmation from the airplane and equipment manufacturers that the Honeywell FMS one million word (1M or 700K) databases (9104 cycle or earlier) no longer exist on any of the affected airplanes worldwide.
FAA's Determination
Upon further consideration, we have determined that we need to rescind AD 91-08-51 to eliminate an unnecessary regulation. Operators may remove the AFM revision and the placard that prohibit the use of NDB approaches for landing.
Since this action rescinds a requirement to perform an unnecessary action, it has no adverse economic impact and imposes no additional burden on any person. Therefore, providing notice and opportunity for public comment is unnecessary before this AD is issued, and this AD may be made effective in less than 30 days after it is published in the
Federal Register.
Explanation of Change to Applicability
We have revised the applicability of the existing AD to identify model designations as published in the most recent type certificate data sheet for the affected models.
Comments Invited
Although this is a final rule that was not preceded by notice and an opportunity for public comment, we invite you to submit any written relevant data, views, or arguments regarding this AD. Send your comments to an address listed under ADDRESSES. Include ``Docket No. FAA-2005-22585; Directorate Identifier 2005-NM-041-AD'' at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of the AD. We will consider all comments received by the closing date and may amend the AD in light of those comments.
We will post all comments we receive, without change, to http://dms.dot.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact with FAA personnel concerning this AD. Using the search function of our docket web site, anyone can find and read the comments in any of our dockets,
including the name of the individual who sent the comment (or signed the comment on behalf of an association, business, labor union, etc.). You can review the DOT's complete Privacy Act Statement in the Federal Register published on April 11, 2000 (65 FR 19477-78), or you can visit http://dms.dot.gov.
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, Section 106, describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes inmore detail the scope of the Agency's authority.
We are issuing this rulemaking under the authority described in subtitle VII, part A, subpart III, section 44701, ``General
requirements.'' Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this rulemaking action.
Regulatory Impact
The regulations adopted herein will not have a substantial direct effect on the States, on the relationship between the national Government and the States, or on the distribution of power and responsibilities among the various levels of government. Therefore, it is determined that this final rule does not have federalism implications under Executive Order13132.
For the reasons discussed above, I certify that this action (1) is not a ``significant regulatory action'' under Executive Order 12866; (2) is not a ``significant rule'' under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and (3) will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. A final evaluation has been prepared for this action and it is contained in the Rules Docket. A copy of it may be obtained from the Rules Docket at the location provided under the caption

List of Subjects in 14 CFR Part 39

The Rescission
Accordingly, according to the authority delegated to me by the Administrator, the FAA proposes to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) as follows:
PART 39--AIRWORTHINESS DIRECTIVES
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
2. The Federal Aviation Administration (FAA) amends Sec. 39.13 by adding an airworthiness directive (AD) that removes amendment 39-7031 (56 FR 26610, June 10, 1991), to read as follows:
