Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA amends 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.

**§ 39.13 [Amended]**

■ 2. The FAA amends § 39.13 by adding the following new AD: 2013–05–20 Rolls-Royce Deutschland Ltd & Co KG (formerly Rolls-RoyceDeutschland GmbH, formerly RollsRoyce plc): Amendment 39–17392; Docket No. FAA–2012–1006; Directorate Identifier 2012–NE–28–AD.
(a) Effective Date

This airworthiness directive (AD) becomes effective April 24, 2013.
(b) Affected ADs

None. (c) Applicability

This AD applies to Rolls-Royce Deutschland Ltd & Co KG (RRD) Spey 511– 8 turbojet engines, serial numbers 8847, 8853, 8879, 8989, 8994, and 9817, with a date of the last shop visit before November 15,
2007.
(d) Reason

This AD was prompted by a recent quality review determination that bolts with reduced material properties may have been installed in some engines. We are issuing this AD to prevent uncontained turbine disc fracture and damage to the airplane.
(e) Actions and Compliance

Unless already done, do the following actions for engines with a date of the last shop visit before November 15, 2007:

(1) If engine cycles accumulated since the last engine shop visit are 4,400 cycles or more on the effective date of this AD, visually inspect the bolts installed in the low-pressure turbine (LPT) support assembly, high-pressure turbine (HPT) bearing support assembly, and HPT air seal sleeve within 100 engine cycles-in-service.

(2) If engine cycles accumulated since the last engine shop visit are fewer than 4,400 cycles on the effective date of this AD, visually inspect the bolts installed in the LPT support assembly, HPT bearing support assembly, and HPT air seal sleeve before accumulating 4,500 engine cycles since the last shop visit.

(3) If you identify any broken bolt, brown bolt, or bolt with a rough oxidized surface, replace all bolts of the inspected engine flange with new bolts before further flight.

(4) If you find any broken bolt in the LPT support assembly, visually inspect the LPT stage 2 disc for damage before further flight.

(5) If you find any broken bolt in the HPT shaft air seal sleeve, visually inspect the HPT stage 1 disc for damage before further flight.

(f) Installation Prohibition

After the effective date of this AD, do not install any LPT support assembly, HPT bearing support assembly, or HPT air seal sleeve into any engine, or any engine onto an airplane, unless the affected bolts have been inspected and replaced if necessary, and the LPT stage 2 disc and HPT stage 1 disc have been inspected if necessary, as specified in paragraph (e) of this AD.
(g) Definition

For the purpose of this AD, a shop visit is when the engine is inducted into the shop for any maintenance involving the separation of pairs of major mating engine flanges (lettered flanges). However, the separation of engine flanges solely for the purposes of transporting the engine without subsequent engine maintenance is not an engine shop visit.
(h) Alternative Methods of Compliance (AMOCs)

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

**SUPPLEMENTARY INFORMATION :**  History

On May 9, 2012, the FAA published in the Federal Register a notice of proposed rulemaking to modify controlled airspace at Scammon Bay, AK (77 FR 27146). Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal to the FAA. No comments were received.

Class E airspace designations 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 designations


### 17084 Federal Register / Vol. 78, No. 54 / Wednesday, March 20, 2013 / Rules and Regulations

listed in this document will be published subsequently in that Order.

The Rule

This action amends Title 14 Code of Federal Regulations (14 CFR) part 71 by modifying Class E airspace extending upward from 700 feet above the surface, at Scammon Bay Airport, Scammon Bay, AK. Additional controlled airspace is necessary to accommodate aircraft using the new RNAV (GPS) standard instrument approach procedures at Scammon Bay Airport and for the safety and management of IFR operations.

The FAA has determined this regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. Therefore, this 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 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 discusses 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 modifies controlled airspace at Scammon Bay Airport, Scammon Bay, AK.

Environmental Review

The FAA has determined that this action qualifies for categorical exclusion under the National Environmental Policy Act in accordance with FAA Order 1050.1E, ‘‘Environmental Impacts: Policies and Procedures,’’ paragraph 311a. This airspace action is not expected to cause any potentially significant environmental impacts, and no extraordinary circumstances exist that warrant preparation of an environmental assessment. List of Subjects in 14 CFR Part 71 Airspace, Incorporation by reference, Navigation (air). Adoption of the Amendment

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