Subject

(d) Air Transport Association (ATA) of America Code 34: Navigation.

Unsafe Condition

(e) This AD results from reports of anomalies with TCAS units during a flight test over a high density airport. The TCAS units dropped several reduced surveillance aircraft tracks because of interference limiting. The Federal Aviation Administration is issuing this AD to prevent TCAS units from dropping tracks, which could compromise separation of air traffic and lead to subsequent mid-air collisions. Compliance

(f) You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done. Upgrade Software

(g) Within 48 months after the effective date of this AD, upgrade software for the ACSS TCAS, in accordance with the Accomplishment Instructions of the applicable ACSS service bulletin identified in Table 1 of this AD.

Note 1: ACSS Publication Number 8008233–001, dated June 4, 2010, ATA Service Bulletin 9000000–34–6016, contains three part numbers (P/Ns 9000000–10007, –20007, and –55007) which were never produced. Alternative Methods of Compliance (AMOCs)

(h)(1) The Manager, Los Angeles Aircraft Certification Office (ACO), FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to Attn: Abby Malmir, Aerospace Engineer, Systems and Equipment Branch, ANM–130L, FAA, Los Angeles ACO, 3960 Paramount Boulevard, Lakewood, California 90712–4137; telephone (562) 627–5351; fax (562) 627–5210.

(2) To request a different method of compliance or a different compliance time for this AD, follow the procedures in 14 CFR 39.19. Before using any approved AMOC on any airplane to which the AMOC applies, notify your principal maintenance inspector (PMI) or principal avionics inspector (PAI), as appropriate, or lacking a principal inspector, your local Flight Standards District Office. The AMOC approval letter must specifically reference this AD.

Issued in Renton, Washington, on December 13, 2010. Ali Bahrami, Manager, Transport Airplane Directorate, Aircraft Certification Service.

You may review the public docket containing the proposal, any comments received and any final disposition in person in the Dockets Office ( see **ADDRESSES** section for address and phone number) between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. An informal docket may also be examined during normal business hours at the office of the Central Service Center, 2601 Meacham Blvd., Fort Worth, TX 76137.

Persons interested in being placed on a mailing list for future NPRMs should contact the FAA’s Office of Rulemaking (202) 267–9677, to request a copy of Advisory Circular No. 11–2A, Notice of Proposed Rulemaking Distribution System, which describes the application procedure. The Proposal

This action proposes to amend Title 14, Code of Federal Regulations (14 CFR), part 71 by amending Class E airspace extending upward from 700 feet above the surface for SIAP operations at M. Graham Clark-Taney Field Airport, Point Lookout, MO. Controlled airspace is needed for the safety and management of IFR operations at the airport. The airport name also would be changed from M. Graham Clark Airport to M. Graham Clark-Taney Field Airport.

Class E airspace areas are published in Paragraph 6005 of FAA Order 7400.9U, dated August 18, 2010 and effective September 15, 2010, which is incorporated by reference in 14 CFR 71.1. The Class E airspace designation listed in this document would be published subsequently in the Order.

The FAA has determined that this proposed regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. It, therefore, (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) does not warrant preparation of a Regulatory Evaluation as the anticipated impact is so minimal. Since this is a routine matter that will only affect air traffic procedures and air navigation, it is certified that this rule, when promulgated, will not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

The FAA’s authority to issue rules regarding aviation safety is found in Title 49 of the U.S. Code. Subtitle 1, section 106 describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the agency’s authority. This rulemaking is promulgated under the authority described in subtitle VII, part A, subpart I, section 40103. Under that section, the FAA is charged with prescribing regulations to assign the use of airspace necessary to ensure the safety of aircraft and the efficient use of airspace. This regulation is within the scope of that authority as it would amend controlled airspace at M. Graham Clark-Taney Field Airport, Point Lookout, MO. List of Subjects in 14 CFR Part 71

Airspace, Incorporation by reference, Navigation (Air). The Proposed Amendment

In consideration of the foregoing, the Federal Aviation Administration proposes to amend 14 CFR part 71 as follows:

**PART 71—DESIGNATION OF CLASS A, B, C, D, AND E AIRSPACE AREAS; AIR**  **TRAFFIC SERVICE ROUTES; AND REPORTING POINTS** 

1. The authority citation for part 71 continues to read as follows:

**§ 71.1 [Amended]**

2. The incorporation by reference in 14 CFR 71.1 of FAA Order 7400.9U, Airspace Designations and Reporting Points, dated August 18, 2010, and effective September 15, 2010, is amended as follows:
Paragraph 6005 Class E Airspace areas extending upward from 700 feet or more above the surface of the earth.

119 ° bearing from the airport extending from the 6.5-mile radius to 9.7 miles southeast of the airport, and within 3.9 miles each side of the 299 ° bearing from the airport extending from the 6.5-mile radius to 10.6 miles southeast of the airport.
