SUPPLEMENTARY INFORMATION: tkelley on DSK3SPTVN1PROD with PROPOSALS Background Rural Development is a mission area within the U.S. Department of Agriculture comprising the Rural Utilities Service, Rural Housing Service and Rural Business/Cooperative Service. Rural Development’s mission is to increase economic opportunity and improve the quality of life for all rural Americans. Rural Development meets its mission by providing loans, loan guarantees, grants and technical assistance through more than 40 programs aimed at creating and improving housing, businesses and infrastructure throughout rural America. The Rural Utilities Service (RUS) loan, loan guarantee and grant programs act as a catalyst for economic and community development. By financing improvements to rural electric, water and waste, and telecom and broadband infrastructure, RUS also plays a big role in improving other measures of quality of life in rural America, including public health and safety, environmental protection, conservation and cultural and historic preservation. In order to continue to facilitate the programmatic interest of the Rural Electrification Act of 1936 (the ‘‘RE Act’’), as amended (7 U.S.C. 901 et seq.), that loans and loans guaranteed by RUS are adequately secured, RUS has established the use of certain standardized forms for materials, equipment, and construction of electric and telecommunications systems. The use of standard forms, construction contracts, and procurement procedures help to assure that appropriate standards and specifications are maintained by the borrower in order to VerDate Sep<11>2014 19:05 Sep 30, 2015 Jkt 238001 not adversely affect RUS’s loan security, and ensure that loan and loan guarantee funds are effectively used for the intended purpose(s). RUS may, from time to time, promulgate new contract forms or revise or eliminate existing contract forms. In so doing, RUS is required by 7 CFR 1755.29, to publish a notice of rulemaking in the Federal Register announcing, as appropriate, a revision in, or a proposal to amend § 1755.30(c), List of telecommunications standard contract forms. On February 12, 2014, RUS published a proposed rule in the Federal Register, (79 FR 8327) to establish a New Equipment Contract and associated Policies for Telecommunications and Broadband Borrowers, RUS Form 395 under 7 CFR parts 1753 and 1755. RUS Form 395, reflects present business and RUS practices, as well as changes in technology, services and equipment. It has come to the attention of the Agency that the proposed rule published in the Federal Register was not clear on how or where to obtain a copy of the proposed new Equipment Contract, RUS Form 395. RUS is issuing this Request for comments to provide an opportunity for interested persons to obtain a copy of the new RUS Form 395 for their review and comment. The information collection and recordkeeping requirements associated with the new RUS Form 395 and its associated forms were submitted to OMB on February 12, 2014 and filed with comment. The purpose of this undertaking is to improve the customer service provided by RUS’s rural telecommunications and broadband borrowers. Changes in competition, legislation, technologies, and regulation have resulted in changes to business practices in the communications industry. In response to these changes RUS has undertaken a comprehensive review of its Telecommunications and Broadband Programs’ contracts and contracting procedures. The new Equipment Contract, RUS Form 395 and the associated close-out documents (Forms 395a, 395b, 395c and 395d) will replace the current Equipment Specific Contracts, RUS Forms 397, 398, 525, 545, and the associated close-out documents (Forms 231, 396, 396a, 517, 744, 752, 752a, and 754). The contract terms and obligations included in the new RUS Form 395, Equipment Contract, reflect current RUS and private sector industry practices, as well as changes in technology, services and equipment. The intent here is to streamline the contractual process for RUS borrowers and expedite the process of approving equipment procurement PO 00000 Frm 00005 Fmt 4702 Sfmt 4702 59081 during RUS funded construction projects.

Airworthiness Directives; Engine Alliance Turbofan Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Engine Alliance (EA) GP7270 turbofan engines. This proposed AD 
was prompted by the manufacturer informing us that the inspection and 
repair criteria in the maintenance manual for aft bolt holes of the 
high-pressure compressor (HPC) cone shaft on the affected engines is 
incorrect. This proposed AD would require inspection of the HPC cone 
shaft and repair of affected parts, if needed. We are proposing this AD 
to prevent failure of the HPC cone shaft, which could lead to 
uncontained engine failure and damage to the airplane.

DATES: We must receive comments on this proposed AD by November 30, 
2015.

SUPPLEMENTARY INFORMATION: 

Comments Invited

    We invite you to send any written relevant data, views, or 
arguments about this proposal. Send your comments to an address listed 
under the ADDRESSES section. Include ``Docket No. FAA-2015-3585; 
Directorate Identifier 2015-NE-22-AD'' at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of this proposed AD. We 
will consider all comments received by the closing date and may amend 
this proposed AD because of those comments.
    We will post all comments we receive, without change, to https://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this proposed AD.

Discussion

    We learned from the manufacturer that the inspection criteria and 
the repair procedures for the aft bolt holes of the HPC cone shaft, 
also referred to as the ``HPC forward stub shaft,'' were listed 
incorrectly in the maintenance manual for the Engine Alliance GP7270 
turbofan engines. HPC cone shafts inspected or repaired using the 
incorrect criteria in the maintenance manual could result in premature 
cracking of these parts. This condition, if not corrected, could result 
in failure of the HPC cone shaft, which could lead to uncontained 
engine failure and damage to the airplane.

Relevant Service Information Under 1 CFR Part 51

    Engine Alliance has issued EA Service Bulletin (SB) No. EAGP7-72-
329, dated July 21, 2015; and EA SB No. EAGP7-72-330, dated July 21, 
2015. The SBs describe procedures for shotpeening and inspection of the 
HPC cone shaft. This service information is reasonably available 
because the interested parties have access to it through their normal 
course of business or by the means identified in the ADDRESSES section 
of this NPRM.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would require inspection of the HPC cone shaft and 
repair of affected parts, if needed.

Costs of Compliance

    We estimate that this proposed AD affects zero engines installed on 
airplanes of U.S. registry. The average labor rate is $85 per hour. 
Based on these figures, we estimate the cost of this proposed AD on 
U.S. operators to be $0.

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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 proposed 
regulation:
    (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.
