**Federal Employees’ Group Life Insurance Program: Providing Option**  **C Coverage for Children of Same-Sex Domestic Partners; Withdrawal** 

**AGENCY :**  U.S. Office of Personnel Management.

**ACTION :**  Notice of proposed rulemaking; withdrawal.

**SUMMARY :**  The United States Office of Personnel Management (OPM) hereby withdraws a notice of proposed rulemaking (NPRM) to amend the Federal Employees’ Group Life Insurance (FEGLI) regulations to allow children of same-sex domestic partnersliving in states that do not allow samesex couples to marry to be covered as family members under an eligible individual’s FEGLI Option C enrollment.

**DATES :**  The proposed rule, published on October 15, 2014, in the Federal Register (79 FR 61788 –61790), is withdrawn as of November 10, 2015.

**FOR FURTHER INFORMATION CONTACT :**  Ronald Brown, Policy Analyst, (202) 606–0004, or by email to Ronald.Brown@opm.gov.

**SUPPLEMENTARY INFORMATION :**  The Office of Personnel Management is withdrawing the proposed rule published October 15, 2014 entitled, ‘‘Federal Employees’ Group Life Insurance Program: Providing Option C Coverage for Children of Same-Sex Domestic Partners’’ (79 FR 61788– 61790). The proposed regulation would have allowed children of same-sex domestic partners living in states that do not allow same-sex couples to marry to be covered as family members under an eligible individual’s FEGLI Option C enrollment. On June 26, 2015, the United States Supreme Court ruled in Obergefell v. Hodges that the Fourteenth Amendment requires a State to license a marriage between two people of the same sex and to recognize a marriage between two people of the same sex when their marriage was lawfully licensed and performed out-of-State. As a result, all states are required to allow same-sex couples to marry, meaning no additional children would be eligible for coverage based on the proposed rule. For this reason, the Office of Personnel Management withdraws the proposed rule to amend the FEGLI regulation to allow children of same-sex domestic partners living in states that do not allow same-sex couples to marry to be covered as family members under an eligible individual’s FEGLI Option C enrollment. U.S. Office of Personnel Management. Beth F. Cobert, Acting Director.

**Airworthiness Directives; Pratt & Whitney Canada Corp. Turboprop**  **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 Pratt & Whitney Canada Corp. (PWC) PT6A–60AG, –65AG, –67AF, and –67AG turboprop engines. This proposed AD was prompted by incidents of corrosion and perforation of the two-ply Cu-Be bellows in Woodward fuel control units (FCUs). This proposed AD would require removing the Woodward FCU and installing an FCU that is eligible for installation. We are proposing this AD to prevent failure of the Woodward FCU, which could lead to failure of the engine, in-flight shutdown, and loss of control of the airplane.

Discussion

The Transport Canada Civil Aviation, which is the aviation authority for Canada, has issued Canada AD CF– 2015–23, dated July 23, 2015 (referred to hereinafter as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states:

There have been in-service incidents involving corrosion and perforation of the two-ply Cu-Be bellows in Woodward Fuel Control Units (FCU) fitted to PT6A–60, –65 and –67 series engines. In certain instances, associated bellows leakage has resulted in loss of engine power, in-flight shutdowns (IFSD) and even accidents. Engines installed on the aeroplanes that are used for crop dusting, due to the operational environment, are more susceptible to corrosion damage to the subject bellows.

Loss of engine power or shut down in flight by itself usually is not considered a catastrophic event. However, on an aeroplane with single engine installation, an engine power loss or IFSD at a critical phase of flight could adversely affect the safe operation of the aeroplane.

This AD affects the PT6A–60AG, PT6A–65AG, PT6A–67AF, and PT6A– 67AG engine models because they have the affected Woodward FCUs installed.

You may obtain further information by examining the MCAI in the AD docket on the Internet at http:// www.regulations.gov by searching for and locating Docket No. FAA–2015–
3732.

Related Service Information Under 1 CFR Part 51

PWC has issued Service Bulletin (SB) No. PT6A–72–14389, Revision 3, dated January 27, 2011 and SB No. PT6A–72– 13473, Revision 1, dated May 26, 2015. The service information describes procedures for replacing Woodward FCUs. 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 and Requirements of This Proposed AD

This product has been approved by the aviation authority of Canada, and is approved for operation in the United States. Pursuant to our bilateral agreement with Canada, they have notified us of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all information provided by Transport Canada Civil Aviation and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. This NPRM would require replacing the Woodward FCU. Costs of Compliance

We estimate that this proposed AD affects 341 engines installed on airplanes of U.S. registry. We also estimate that it would take about 1.5 hours per engine to comply with this proposed AD. The average labor rate is $85 per hour. Required parts cost about $1,000 per engine. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $384,478. 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. List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
