Download as PDF 51170 Proposed Rules Federal Register Vol. 82, No. 212 Friday, November 3, 2017 This section of the FEDERAL REGISTER contains notices to the public of the proposed issuance of rules and regulations. The purpose of these notices is to give interested persons an opportunity to participate in the rule making prior to the adoption of the final rules. OFFICE OF PERSONNEL MANAGEMENT 5 CFR 890 RIN: 3206–AN33 Federal Employees Health Benefits (FEHB) Program: FEHB Employee Premium Contributions for Employees in Leave Without Pay or Other Nonpay Status U.S. Office of Personnel Management. ACTION: Proposed rule; withdrawal. AGENCY: The United States Office of Personnel Management (OPM) is withdrawing a previously published Notice of Proposed Rulemaking (NPRM) that would have amended the Federal Employees Health Benefits (FEHB) regulations at 5 CFR part 890 to provide flexibility to agencies regarding payment for FEHB coverage for employees entering leave without pay (LWOP) or any other type of nonpay status, except when nonpay is as a result of a lapse of appropriations. The regulation also would have affected employees who have insufficient pay to cover their premium contribution, and certain categories of employees were exempt. DATES: OPM is withdrawing the proposed rule published August 30, 2016 (81 FR 59518) as of November 3, 2017. FOR FURTHER INFORMATION CONTACT: Julia Elam, Program Analyst at (202) 606– 0004. SUPPLEMENTARY INFORMATION: On August 30, 2016, OPM published an NPRM (81 FR 59518) that would complement the FEHB Modification of Eligibility final regulation (79 FR 62325, published on October 17, 2014) which allows generally for certain temporary, intermittent and seasonal employees to enroll in the FEHB Program if they are expected to work at least 130 hours per month for at least 90 days. In the NPRM, OPM recognized that the expansion of eligibility for FEHB coverage may jstallworth on DSKBBY8HB2PROD with PROPOSALS SUMMARY: VerDate Sep<11>2014 15:06 Nov 02, 2017 Jkt 244001 impact an agency’s budget due to the required FEHB Government health benefit contributions for newly eligible employees who elect to participate in FEHB coverage and go into LWOP or other nonpay status based on the intermittent nature of the work performed. The NPRM would have provided flexibility to agencies regarding payment for FEHB coverage for employees entering leave without pay (LWOP) or any other type of nonpay status, except when nonpay is as a result of a lapse of appropriations. OPM received comments from Federal employees, Federal agencies, a Federal shared service provider, and unions representing Federal employees. The majority of commenters objected to the regulation based on concerns that the rule would place an undue financial burden on Federal employees on LWOP or other nonpay status and would make it difficult for these employees to maintain health insurance. OPM also received comments about the impact of the rule on Permanent Seasonal Employees (PSEs). The commenters stated that PSEs are placed in nonpay status annually and there is a reasonable expectation that these employees will return to employment and repay the unpaid premiums that have been incurred as a debt. In reviewing these objections, OPM attempted to determine whether the potential cost savings from this proposed rulemaking outweighs the negative impact asserted by commenters. To estimate cost savings, OPM requested the current amount of unrecoverable premium debt from employees on LWOP and nonpay status from several agencies with large numbers of temporary, seasonal and intermittent employees. However, these agencies were generally unable to provide this data. Agencies do not have reliable data on unrecoverable FEHB debt because, due to constantly changing circumstances, these amounts are difficult to track. OPM did obtain one estimate of unpaid FEHB debt or FEHB debt in default for all employees on seasonal and intermittent Schedules in LWOP or insufficient pay for one agency for FY2016. The agency reported that total FEHB debt incurred by the agency for these employees was $1,068,065, but that only $48,797 of this total debt remained unpaid by employees once they returned to pay (or PO 00000 Frm 00001 Fmt 4702 Sfmt 4702 sufficient pay) status. Further, there are debt collection mechanisms in place to recover the remaining $48,797. Agencies must already comply with the Debt Collection Improvement Act (DCIA) of 1996 (DCIA) to collect delinquent debt, including FEHB debt. Therefore, appropriate actions are being taken for the collection of FEHB debt for employees entering leave without pay (LWOP) or any other type of nonpay status. OPM determined that the potential cost savings from this proposed rulemaking does not outweigh the potential negative impact of the undue financial burden or risk of losing health insurance on certain Federal employees. Withdrawal of this NPRM (81 FR 59518, August 30, 2016) does not preclude the agency from issuing future rulemakings on this issue, nor does it commit the agency to any course of action in the future.

Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA AD No. 2016–0235, dated November 24, 2016 (referred to hereinafter as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: Some cases were reported of ruptured front support pins on ARRIEL 1E2 engines. That condition, if not detected and corrected, could lead to the loss of the load path integrity of the engine front support. ´ Consequently, Turbomeca issued Mandatory Service Bulletin (MSB) 292 72 0842 to provide instructions for the inspection of the pins and front support replacement, and EASA issued AD 2015–0064 (later revised) to require those actions. Since EASA AD 2015– 0064R1 was issued, SAFRAN Helicopter Engines developed a new pin design, in order to increase the mechanical strength of the pin, through modification TU380, for ARRIEL 1E2 engines. Although no cases of front support pin rupture have been reported on ARRIEL 2E engines, since the ARRIEL 1E2 and 2E type designs have the same front support, SAFRAN Helicopter Engines decided to also apply this new pin design on ARRIEL 2E engines through modification TU197. To address this potential unsafe condition, SAFRAN Helicopter Engines decided, as precautionary measure, to replace the front support on ARRIEL 2E engines, and published MSB 292 72 2197 to provide instructions for in-service front support replacement. For the reasons described above, this AD requires modification of the affected engines by replacement of each premod TU197 front support. 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–2017– 0838. Related Service Information We reviewed Safran Helicopter Engines, S.A., Mandatory Service Bulletin (MSB) No. 292 72 2197, Version A, dated September 15, 2016. The MSB describes procedures for replacement of the accessory gearbox front support. 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. FAA’s Determination and Requirements of This Proposed AD This product has been approved by the aviation authority of France, and is approved for operation in the United States. Pursuant to our bilateral agreement with the European Community, EASA has notified us of the unsafe condition described in the MCAI. We are proposing this AD because we evaluated all information provided by EASA and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. This proposed AD would require for replacement of the accessory gearbox front support. Costs of Compliance We estimate that this proposed AD affects 28 engines installed on aircraft of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS jstallworth on DSKBBY8HB2PROD with PROPOSALS Action Labor cost Front support replacement .............................. 2 work-hours × $85 per hour = $170 ............. 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: VerDate Sep<11>2014 15:06 Nov 02, 2017 Jkt 244001 Parts cost Aviation Programs,’’ describes in more detail the scope of the Agency’s authority.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
AD No. 2016-0235, dated November 24, 2016 (referred to hereinafter as 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    Some cases were reported of ruptured front support pins on 
ARRIEL 1E2 engines. That condition, if not detected and corrected, 
could lead to the loss of the load path integrity of the engine 
front support. Consequently, Turbom[eacute]ca issued Mandatory 
Service Bulletin (MSB) 292 72 0842 to provide instructions for the 
inspection of the pins and front support replacement, and EASA 
issued AD 2015-0064 (later revised) to require those actions. Since 
EASA AD 2015-0064R1 was issued, SAFRAN Helicopter Engines developed 
a new pin design, in order to increase the mechanical strength of 
the pin, through modification TU380, for ARRIEL 1E2 engines. 
Although no cases of front support pin rupture have been reported on 
ARRIEL 2E engines, since the ARRIEL 1E2 and 2E type designs have the 
same front support, SAFRAN Helicopter Engines decided to also apply 
this new pin design on ARRIEL 2E engines through modification TU197. 
To address this potential unsafe condition, SAFRAN Helicopter 
Engines decided, as precautionary measure, to replace the front 
support on ARRIEL 2E engines, and published MSB 292 72 2197 to 
provide instructions for in-service front support replacement. For 
the reasons described above, this AD requires modification of the 
affected engines by replacement of each pre-mod TU197 front support.

docket on the Internet at http://www.regulations.gov by searching for 
and locating Docket No. FAA-2017-0838.

Related Service Information

    We reviewed Safran Helicopter Engines, S.A., Mandatory Service 
Bulletin (MSB) No. 292 72 2197, Version A, dated September 15, 2016. 
The MSB describes procedures for replacement of the accessory gearbox 
front support. 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.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of France, 
and is approved for operation in the United States. Pursuant to our 
bilateral agreement with the European Community, EASA has notified us 
of the unsafe condition described in the MCAI. We are proposing this AD 
because we evaluated all information provided by EASA and determined 
the unsafe condition exists and is likely to exist or develop on other 
products of the same type design. This proposed AD would require for 
replacement of the accessory gearbox front support.

Costs of Compliance

    We estimate that this proposed AD affects 28 engines installed on 
aircraft of U.S. registry.
    We estimate the following costs to comply with this proposed AD:

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

[[Page 51172]]

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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to engines, propellers, and 
associated appliances to the Manager, Engine and Propeller Standards 
Branch, Policy and Innovation Division.

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, 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.
