■ 1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

**§ 39.13 [Amended]**

■ 2. The FAA amends § 39.13 by adding the following new airworthiness directive (AD): The Boeing Company: Docket No. FAA– 2008–0614; Directorate Identifier 2007– NM–351–AD.
(a) Comments Due Date

We must receive comments by March 18,
2013.
(b) Affected ADs

None. (c) Applicability

This AD applies to all The Boeing Company Model 737–300, –400, and –500 series airplanes, certificated in any category.
(d) Subject

Joint Aircraft System Component (JASC)/ Air Transport Association (ATA) of America Code 2800, Aircraft Fuel System.
(e) Unsafe Condition

This AD was prompted by reports of two in-service occurrences on Model 737–400 airplanes of total loss of boost pump pressure of the fuel feed system, followed by loss of fuel system suction feed capability on one engine, and in-flight shutdown of the engine. We are issuing this AD to detect and correct loss of the engine fuel suction feed capability of the fuel system, which in the event of total loss of the fuel boost pumps could result in dual engine flameout, inability to restart the engines, and consequent forced landing of the airplane.

Comply with this AD within the compliance times specified, unless already done.
(g) Operational Test and Corrective Actions

Within 7,500 flight hours or 24 months after the effective date of this AD, whichever occurs first: Perform an operational test of the engine fuel suction feed of the fuel system, and do all applicable corrective actions, in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin 737–28A1307, dated May 14, 2012. Do all applicable corrective actions before further flight. Repeat the operational test thereafter at intervals not to exceed 7,500 flight hours or 24 months, whichever occurs first. Thereafter, except as provided in paragraph (h) of this AD, no alternative procedures or repetitive test intervals are allowed.
(h) Alternative Methods of Compliance (AMOCs)

(1) The Manager, Seattle 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.

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

The FAA is proposing an amendment to Title 14, Code of Federal Regulations (14 CFR) part 71 to modify the Nashville International Airport Class C airspace area by removing a cutout from the Class C surface area that excluded the airspace within a 1.5 NM radius of the former Cornelia Fort Airpark from the Class C surface area. The exclusion was in place to solely accommodate operations at the Airpark, which was located about 4 NM north northwest of Nashville International Airport. The Airpark is now permanently closed and the property sold for non-aviation uses. Since the original purpose of the exclusion no longer exists, the FAA is proposing to remove the words ‘‘ * * * excluding that airspace within a 1.5- mile radius of lat. 36 ° 12 ′00 ′′ N., long.
86 ° 42 ′ 10 ′′ W. (in the vicinity of Cornelia Fort Airpark) * * * ’’ from the Class C airspace description. This would restore the Class C surface area to the standard configuration of a 5 NM radius around Nashville International Airport and would enhance the management of aircraft operations at the airport.

Also, a minor correction would be made to update the geographic coordinates of the Nashville International Airport to reflect the current information in the FAA’s aeronautical database. This change would remove ‘‘lat. 36 ° 07 ′ 31 ′′ N., long.
86 ° 40 ′ 35 ′′ W.,’’ and insert ‘‘lat. 36 ° 07 ′ 28 ′′ N., long. 86 ° 40 ′42 ′′ W.’’ in its place. Class C airspace areas are published in paragraph 4000 of FAA Order 7400.9W, dated August 8, 2012 and effective September 15, 2012, which is incorporated by reference in 14 CFR 71.1. The Class C airspace area modification proposed 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. Therefore, this proposed regulation: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866; (2) is not a ‘‘significant rule’’ under Department of Transportation (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 proposed 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 United States Code. Subtitle I, 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 the 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 modify terminal airspace as required to preserve the safe and efficient flow of air traffic in the Nashville, TN, area.
