Download as PDF pmangrum on DSK3GDR082PROD with PROPOSALS1 42752 Federal Register / Vol. 82, No. 175 / Tuesday, September 12, 2017 / Proposed Rules the best position to help CBP identify rules that are obsolete, unnecessary, unjustified, or simply no longer make sense, or rules that could be better modernized to accomplish their objectives. Consistent with CBP’s commitment to public participation in the rulemaking process, CBP is soliciting views from the public on specific regulations or paperwork requirements that could be altered or eliminated to reduce burdens while still allowing CBP to meet its mission. While CBP promulgates rules in accordance with the law and to the best of its analytic capability, it is difficult to be certain of the consequences of a rule, including its costs and benefits, until it has been tested. Because knowledge about the full effects of a rule is widely dispersed in society, members of the public are likely to have useful information and perspectives on the benefits and burdens of existing requirements and how regulatory obligations may be updated, streamlined, revised, or repealed to better achieve regulatory objectives, while minimizing regulatory burdens, consistent with applicable law. Accordingly, CBP is asking you to consider the following questions when providing your input: (1) Are there CBP rules or reporting requirements that have become outdated and, if so, how can they be modernized to better accomplish their objective? (2) Are there CBP rules that are still necessary, but have not operated as well as expected such that a modified, or slightly different approach at lower cost is justified? (3) Are there CBP rules that unnecessarily obstruct, delay, curtail, or otherwise impose significant costs on the secure flow of legitimate trade and travel to and from the United States? (4) Does CBP currently collect information that it does not need or use effectively? (5) Are there regulations, reporting requirements, or regulatory processes that are unnecessarily complicated or could be streamlined to achieve statutory obligations in more efficient ways? (6) Are there rules or reporting requirements that have been overtaken by technological developments? Can new technologies be leveraged to modify, streamline, or do away with existing regulatory or reporting requirements? To allow CBP to more effectively evaluate suggestions, CBP requests that commenters identify with specificity the regulation (in either Title 19 CFR Chapter I, or Title 8 CFR, Chapter I) or VerDate Sep<11>2014 15:03 Sep 11, 2017 Jkt 241001 reporting requirement at issue, and provide the legal citation where available. Please note that certain regulations which reflect statutory requirements cannot be eliminated until the statute is amended or repealed to eliminate that requirement. CBP also requests that the submitter provide, in as much detail as possible, an explanation why a regulation or reporting requirement should be modified, streamlined, or repealed, as well as specific suggestions of ways CBP can do so while achieving its regulatory objectives. In addition, supporting data or other information, such as cost information, for any suggestions would be useful. Comments from the public are crucial to understanding regulatory burden and helping CBP find solutions that are cost effective, facilitate legitimate trade and travel, and enhance homeland security. While CBP intends to fully consider all input received in response to this notice, CBP will not respond individually to comments and none of the comments submitted will bind CBP to take any further action.

We will post all comments we receive, without change, to http:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this NPRM. Discussion We received a report of an LPT uncontainment on a CF6–80A2. Investigation determined the 42753 uncontainment was the result of HCF cracking of the LPT stage 3 nozzles. This condition, if not corrected, could result in failure of the LPT stage 3 nozzle, damage to the engine, and damage to the airplane. and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. Related Service Information We reviewed GE CF6–80A Service Bulletin (SB) 72–0749, Revision 2, dated August 31, 2016. The SB describes procedures for replacement of the LPT stage 3 nozzles. This proposed AD would require replacement of the LPT stage 3 nozzles. FAA’s Determination We are proposing this AD because we evaluated all the relevant information Proposed AD Requirements Costs of Compliance We estimate that this proposed AD affects 7 engines installed on airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Labor cost Replacement of LPT stage 3 nozzles ............ pmangrum on DSK3GDR082PROD with PROPOSALS1 Action 0 work-hours × $85 per hour = $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. 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 VerDate Sep<11>2014 15:03 Sep 11, 2017 Jkt 241001 Parts cost $368,260 Cost per product $368,260 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. § 39.13 List of Subjects in 14 CFR Part 39 Cost on U.S. operators $2,577,820 (e) Unsafe Condition Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
General Electric Company (GE) CF6-80A, -80A1, -80A2, and -80A3 turbofan 
engines. This proposed AD was prompted by high cycle fatigue (HCF) 
cracking of the low-pressure turbine (LPT) stage 3 nozzles. This 
proposed AD would require replacement of the LPT stage 3 nozzles. We 
are proposing this AD to address the unsafe condition on these 
products.

economic, environmental, and energy aspects of this NPRM. We will 
consider all comments received by the closing date and may amend this 
NPRM because of those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this NPRM.

Discussion

    We received a report of an LPT uncontainment on a CF6-80A2. 
Investigation determined the uncontainment was the result of HCF 
cracking of the LPT stage 3 nozzles. This condition, if not corrected, 
could result in failure of the LPT stage 3 nozzle, damage to the 
engine, and damage to the airplane.

Related Service Information

    We reviewed GE CF6-80A Service Bulletin (SB) 72-0749, Revision 2, 
dated August 31, 2016. The SB describes procedures for replacement of 
the LPT stage 3 nozzles.

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 replacement of the LPT stage 3 
nozzles.

Costs of Compliance

    We estimate that this proposed AD affects 7 engines installed on 
airplanes 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 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.
