comply with this AD. The average labor rate is $85 per hour. Based on these figures, we estimate the cost of this AD on U.S. operators to be $23,800. Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety. 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.

We are issuing this rulemaking under the authority described in ‘‘Subtitle VII, Part A, Subpart III, Section 44701: General requirements.’’ Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. Regulatory Findings

We determined that this AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.

For the reasons discussed above, I certify this AD:

(1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866,

(2) Is not a ‘‘significant rule’’ under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979),

(3) Will not affect intrastate aviation in Alaska to the extent that it justifies making a regulatory distinction, and

(4) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. List of Subjects in 14 CFR Part 39

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 airworthiness directive (AD):
2015–04–06 Rolls-Royce plc Turbofan Engines: Amendment 39–18108; Docket No. FAA–2014–0328; Directorate Identifier 2014–NE–07–AD.

(a) Effective Date

This AD becomes effective April 8, 2015.

(b) Affected ADs

None. (c) Applicability

This AD applies to all Rolls-Royce plc (RR) RB211 Trent 875–17, 877–17, 884–17, 884B– 17, 892–17, 892B–17, and 895–17 turbofan engines.
(d) Reason

This AD was prompted by failure of the intermediate pressure (IP) turbine disk drive arm and subsequent overspeed and burst of the IP turbine disk on an RR RB211 Trent turbofan engine. We are issuing this AD to prevent overspeed of the IP turbine disk, resulting in failure of the turbine blades or the IP turbine disk and subsequent uncontained release of the turbine disk and/ or blades, which could lead to damage to the engine and damage to the airplane.
(e) Actions and Compliance

Twelve months after the effective date of this AD, do not operate any engine with an electronic engine control (EEC) software standard earlier than B7.2.

(f) Installation Prohibition

After removing any software standard earlier than B7.2 from an ECC on any engine, do not operate that engine with any software standard earlier than B7.2.
(g) 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. You may email your request to: ANE-AD-AMOC@faa.gov.

**SUPPLEMENTARY INFORMATION :**  Background

On February 9, 2015, the FAA published a final rule technical amendment entitled, ‘‘Automatic Dependent Surveillance-Broadcast (ADS–B) Out Performance Requirements To Support Air Traffic Control (ATC) Service; Technical Amendment.’’ In that final rule, which became effective February 9, 2015, the FAA amended 14 CFR part 91. The FAA inadvertently listed the incorrect Amendment Number for part 91 in the header information of the final rule as 91–334. The correct amendment number is 91–336.

Correction

In the final rule, FR Doc. 2015–02579, published on February 9, 2015, at 80 FR 6899 make the following correction:

1. On page 6899 in the heading of the final rule, revise ‘‘Amdt. No. 91–334’’ to read ‘‘91–336’’.

**Air Carrier Contract Maintenance Requirements** 

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Final rule.

**SUMMARY :**  The Federal Aviation Administration (FAA) amends the maintenance regulations for domestic, flag, and supplemental operations, and for commuter and on-demand operations for aircraft type certificated with a passenger seating configuration of 10 seats or more (excluding any pilot seat). The new rules require affected air carriers and operators to develop policies, procedures, methods, and instructions for performing contract maintenance that are acceptable to the FAA, and to include them in their maintenance manuals. The rules also require the air carriers and operators to provide a list to the FAA of all persons with whom they contract their maintenance. These changes are needed because contract maintenance has increased to over 70 percent of all air carrier maintenance, and numerous investigations have shown deficiencies in maintenance performed by contract maintenance providers. These rules will help ensure consistency between contract and in-house air carrier maintenance and enhance the oversight capabilities of both the air carriers and the FAA.

**DATES :**  Effective May 4, 2015 except for §§ 121.368 and 135.426 which contain information collection requirements that have not been approved by the Office of Management and Budget (OMB). The FAA will publish a document in the Federal Register announcing the effective date.

**SUPPLEMENTARY INFORMATION :**  Authority for This Rulemaking

The FAA’s authority to issue rules on 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 III, Section 447, Section 44701(a)(2)(A) and (B) and (5). Under that section, the FAA is charged with prescribing regulations and minimum standards in the interest of safety for inspecting, servicing, and overhauling aircraft, aircraft engines, propellers, and appliances, and equipment and facilities for, and the timing of and manner of, the inspecting, servicing and overhauling the FAA finds necessary for safety and commerce. This regulation is within the scope of that authority.

In addition, Public Law 112–95 (February 14, 2012), the ‘‘FAA Modernization and Reform Act of 2012’’ (the Act), in section 319 (Maintenance providers), requires the FAA to issue regulations ‘‘requiring that covered work on an aircraft used to provide air transportation under part 121 . . ., be performed by persons in accordance with subsection (b).’’ Subsection (b), in addition to listing persons authorized under existing regulations, referenced additional terms and conditions in subsection (c) that would apply to persons who provide contract maintenance workers, services, or maintenance functions to a part 121 air carrier for covered work. The Act mandates that the contracting part 121 air carrier be directly in charge of covered work, as defined by the Act, being performed for the carrier under contract, and that the work be done under the supervision and control of the air carrier. These statutory requirements are addressed in this rule.

I. Overview of Final Rule

The FAA is amending Title 14, Code of Federal Regulations (14 CFR) §§ 121.368, 121.369, 135.426, and 135.427. These amendments apply to certificate holders who conduct domestic, flag, or supplemental operations under part 121, and to certificate holders who conduct commuter operations or on-demand operations with aircraft type certificated for a passenger seating configuration, excluding any pilot seat, of ten seats or

more 1 under part 135, if the carriers contract any of their maintenance, preventive maintenance, or alteration work to an outside source. 2 As required by the Act, this final rule addresses the performance of ‘‘covered work.’’ It codifies the statutory definition of the term, and includes requirements for the performance of that work, to include that the certificate holder must be directly in charge of it; the covered work must be carried out in accordance with
