### 15295 Federal Register / Vol. 77, No. 51 / Thursday, March 15, 2012 / Proposed Rules

(d) Subject

Air Transport Association (ATA) of America Code 24: Electrical Power.

(e) Reason

This AD was prompted by a determination that additional actions are necessary to address the identified unsafe condition identified in AD 2010–18–03, Amendment 39–16416 (75 FR 51931, August 24, 2010). We are issuing this AD to detect and correct a leakage failure mode of transient voltage suppression (TVS) diodes used on power distribution control units (PDCU) cards or generator control units (GCU) cards in the primary power distribution boxes, which, in combination with other system failures, could lead to loss of controllability of the airplane.
(f) Compliance

You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
(g) Retained Airplane Flight Manual Revision (AFM)

This AFM revision is retained from AD 2010–18–03, Amendment 39–16416 (75 FR 51931, August 24, 2010): Within 30 days after September 8, 2010 (the effective date of AD 2010–18–03, Amendment 39–16416 (75 FR 51931, August 24, 2010)), revise the Abnormal Procedures and Limitations sections of the Dassault F7X AFM to include the following statement. This may be done by inserting copies of this AD into the AFM Limitations section and Abnormal Procedures section.

‘‘Upon display of ELEC:BUS MISCONFIG TIED in Crew Alerting System (Abnormal procedure 3–190–20), land at nearest suitable airport

Upon display of ELEC:LH ESS PWR LO or ELEC:LH ESS NO PWR (Abnormal procedure 3–190–40), land at nearest suitable airport

Upon display of ELEC:RH ESS PWR LO and ELEC:RH ESS NO PWR (Abnormal procedure 3–190–45), land at nearest suitable airport

Upon display of HYD:BACKUP PUMP HI TEMP (Abnormal procedure 3–250–15), set off the pump and if the backup pump is still rotating (green) in hydraulic synoptic, descend to a safe altitude or below 15,000 ft

Caution: These temporary amendments take precedence over the same procedures displayed through the Electronic Check List (ECL) in the aeroplane.’’

Note 1 to paragraph (g) of this AD: When a statement identical to that in paragraph (g) of this AD has been included in the Limitations section and Abnormal Procedures section in the general revisions of the AFM, the general revisions may be inserted into the AFM, and the copy of this AD may be removed.

(h) New Requirements of This AD: Test the PDCU and GCU Cards

For airplanes identified in Dassault Mandatory Service Bulletin 7X–133, dated December 4, 2009: Within 9 months after the effective date of this AD, perform a test of the PDCU and GCU cards to detect faulty components, in accordance with the Accomplishment Instructions of Dassault Mandatory Service Bulletin 7X–133, dated December 4, 2009. If any faulty components are found, before further flight, replace any affected PDCU or GCU card, in accordance with the Accomplishment Instructions of Dassault Aviation Mandatory Service Bulletin 7X–133, dated December 4, 2009.
(i) Optional Method of Compliance

For airplanes identified in Dassault Mandatory Service Bulletin 7X–133, dated December 4, 2009: Accomplishing the actions specified in paragraph (h) of this AD, within 9 months after the effective date of this AD, in accordance with the service information specified in paragraphs (i)(1), (i)(2), and (i)(3) of this AD, is acceptable for compliance with the actions specified in paragraph (h) of this
AD.

(2) Goodrich Service Bulletin 80232191– 24–01, dated August 13, 2009.

(3) Goodrich Service Bulletin 80232192– 24–01, dated August 13, 2009.
(j) Other FAA AD Provisions

The following provisions also apply to this
AD:

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 by modifying Class E airspace extending upward from 700 feet above the surface at Dillon Airport, Dillon, MT. Controlled airspace is necessary to accommodate aircraft using the new RNAV (GPS) standard instrument approach procedures at Dillon Airport. The geographic coordinates of the airport also would be updated to coincide with the FAA’s aeronautical database. This action would enhance the safety and management of aircraft operations at Dillon Airport.

Class E airspace designations are published in paragraph 6005, of FAA Order 7400.9V, dated August 9, 2011, and effective September 15, 2011, which is incorporated by reference in 14 CFR 71.1. The Class E airspace designation listed in this document will be published subsequently in this Order.

The FAA has determined 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 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 this proposed rule, when promulgated, would 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 for 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 create additional controlled airspace at Dillon Airport, Dillon, MT.

This proposal will be subject to an environmental analysis in accordance with FAA Order 1050.1E. ‘‘Environmental Impacts: Policies and Procedures’’ prior to any FAA final regulatory action.

The Proposal

The FAA is considering an amendment to Title 14, Code of Federal Regulations (14 CFR) part 71 to establish Class D airspace, Class E surface area airspace and amend existing Class E airspace extending upward from 700 feet above the surface at East Hampton Airport, East Hampton, NY. Controlled airspace is necessary to support the operation of the new air traffic control tower, and would enhance the safety and management of IFR operations at the airport. Also, the geographic coordinates would be adjusted for the airport’s existing controlled airspace area to be in concert with the FAAs aeronautical database.

Class D and E airspace designations are published in Paragraphs 5000, 6002, and 6005 respectively, of FAA Order 7400.9V, dated August 9, 2011, and effective September 15, 2011, which is incorporated by reference in 14 CFR 71.1. The Class D and E airspace designations listed in this document will 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 proposed rule, when promulgated, would not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
