(d) Reason

This AD was prompted by RRD performing an evaluation that determined that certain HPT stage 1 and stage 2 discs from a specific supplier may contain steel inclusions that may cause the discs to fail before they reach their current life limits. We are issuing this AD to prevent failure of the HPT stage 1 and stage 2 discs, which could result in uncontained failure of the engine and damage to the airplane. (e) Actions and Compliance

Unless already done, remove from service the HPT stage 1 and stage 2 discs listed by S/N in Table 1 to paragraph (c) of this AD, at the following:

(1) For BR700–710A1–10, BR700–710A2– 20, and BR700–710C4–11 engine models (without RRD Mod 72–101466), remove the HPT stage 1 and stage 2 discs from service before accumulating 3,000 cycles-since-new (CSN).

(2) For the BR700–710C4–11 engine model (with RRD Mod 72–101466), remove the HPT stage 1 and stage 2 discs from service before accumulating 2,300 CSN.
(f) Installation Prohibition

After the effective date of this AD, do not install an HPT stage 1 and an HPT stage 2 disc, identified by S/N in Table 1 to paragraph (c) of this AD, in the same engine. (g) Alternative Methods of Compliance (AMOCs)

The Manager, Engine Certification Office, may approve AMOCs for this AD. Use the procedures found in 14 CFR 39.19 to make your request.

### 68717 Federal Register / Vol. 77, No. 222 / Friday, November 16, 2012 / Proposed Rules

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 to accommodate new standard instrument approach procedures at Hot Springs Municipal Airport, Hot Springs, SD. Controlled airspace is needed for the safety and management of IFR operations at the airport. The airport’s geographic coordinates also would be updated to coincide with the FAA’s aeronautical database.

Class E airspace areas are published in Paragraph 6005 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 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 Hot Springs Municipal Airport, Hot Springs, SD. Environmental Review
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. 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 7400.9W, Airspace Designations and Reporting Points, dated August 8, 2012, and effective September 15, 2012, is amended as follows:

Paragraph 6005 Class E airspace areas extending upward from 700 feet or more above the surface of the earth.
