ACTION: Final rule; request for comments. AGENCY: The FAA is superseding airworthiness directive (AD) 2018–25– 01 for all Rolls-Royce plc (RR) Trent 1000–A, Trent 1000–C, Trent 1000–D, Trent 1000–E, Trent 1000–G, and Trent 1000–H turbofan model engines. AD 2018–25–01 required initial and repetitive inspections of the intermediate-pressure compressor (IPC) stage 1 rotor (R1) blades, IPC stage 2 rotor (R2) blades, and IPC shaft stage 2 dovetail posts, and removing any cracked parts from service. This AD retains those inspections, revises certain reinspection intervals, and adds certain engine models to the applicability. This AD was prompted by a determination by the manufacturer of the need to revise inspection intervals for certain affected engines. In addition, the FAA added recently validated additional engine models to the applicability. The FAA is issuing this AD to address the unsafe condition on these products. jspears on DSK3GMQ082PROD with RULES SUMMARY: VerDate Sep<11>2014 17:38 Aug 26, 2019 Jkt 247001 This AD is effective September 11, 2019.

SUPPLEMENTARY INFORMATION: Discussion The FAA issued AD 2018–25–01, Amendment 39–19511 (83 FR 62694, December 6, 2018), (‘‘AD 2018–25–01’’), for all RR Trent 1000–A, Trent 1000–C, Trent 1000–D, Trent 1000–E, Trent 1000–G, and Trent 1000–H turbofan engine models. AD 2018–25–01 required initial inspections and repetitive inspections of the IPC R1 blades, IPC R2 blades, and IPC shaft stage 2 dovetail posts, and removal of any cracked parts from service. AD 2018–25–01 resulted from the manufacturer determining the need for repetitive inspections of the IPC R1 blades, IPC R2 blades, and IPC shaft stage 2 dovetail posts. The FAA issued AD 2018–25–01 to prevent failure of the IPC, which could result in failure of one or more engines, loss of thrust control, and loss of the airplane. Actions Since AD 2018–25–01 Was Issued Since the FAA issued AD 2018–25– 01, RR determined that inspection intervals for certain affected engines need to be revised. Also, since the FAA issued AD 2018–25–01, the European Union Aviation Safety Agency (EASA) has issued EASA AD 2019–0075, dated March 29, 2019 (‘‘the MCAI’’), which requires initial and repetitive inspections of IPC R1 blades, IPC R2 blades, and IPC shaft stage 2 dovetail posts installed on certain engines and removal of any cracked parts from service. Also, since the FAA issued AD 2018– 25–01, the type certificate (TC) for all Trent 1000 turbofan model engines was revised to add RR Trent 1000–AE2 and Trent 1000–CE2 engine models to the list of applicable engine models. Both Trent 1000–AE2 and Trent 1000–CE2 engine models were identified in EASA AD 2019–0075 and are subject to the same unsafe condition as the other models listed in the Applicability of this AD. In addition, Rolls-Royce plc transferred TC E00076EN to Rolls-Royce Deutschland Ltd & Co KG (RRD) on February 21, 2019. The FAA has therefore revised the TC holder name from ‘‘Rolls-Royce plc’’ in AD 2018–25– 01 to ‘‘Rolls-Royce Deutschland Ltd & Co KG’’ in this AD. Where applicable, for example when referring to the relevant service information, the FAA continues to use the name ‘‘Rolls-Royce plc’’ in this AD. The FAA also updated our estimate for labor hours when replacing the IPC E:\FR\FM\27AUR1.SGM 27AUR1 44684 Federal Register / Vol. 84, No. 166 / Tuesday, August 27, 2019 / Rules and Regulations blades and the IPC drum to be consistent with the estimates provided in the service information. The FAA is issuing this AD to address the unsafe condition on these products. Related Service Information Under 1 CFR Part 51 The FAA reviewed RR Alert NonModification Service Bulletin (NMSB) Trent 1000 72–AK130, Revision 4, dated March 4, 2019, and RR NMSB Trent 1000 72–K132, Revision 2, dated March 26, 2019. RR Alert NMSB Trent 1000 72–AK130 describes procedures for performing initial and repetitive inspections of the IPC R1 blades, IPC R2 blades, and IPC shaft stage 2 dovetail posts, and lists engine serial numbers. RR NMSB Trent 1000 72–K132, describes procedures for replacement of the IPC R1 blades, IPC R2 blades, and the IP compressor drum during refurbishment. 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. Other Related Service Information The FAA reviewed RR NMSB Trent 1000 72–K099, Revision 2, dated September 27, 2018, and earlier revisions; RR NMSB Trent 1000 72– K100, Initial Issue, dated June 11, 2018; RR NMSB Trent 1000 72–K129, Initial Issue, dated June 11, 2018; and RR NMSB Trent 1000 72–K129, Revision 3, dated February 28, 2019, and earlier revisions. RR NMSB Trent 1000 72– K099, Initial Issue, and RR NMSB Trent 1000 72–K099, Revision 2, and earlier revisions, describe procedure for an ultrasonic inspection of the IPC R1 blades. RR NMSB Trent 1000 72–K100, Initial Issue, describes procedures for a visual borescope inspection of the IPC R2 blades and IPC shaft stage 2 dovetail posts. RR NMSB Trent 1000 72–K129, Revision 3, and earlier revisions, describe procedures for an ultrasonic inspection of the IPC R2 blades. FAA’s Determination This product has been approved by EASA 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 EASA AD 2019–0075, dated March 29, 2019, and service information referenced above. The FAA is issuing this AD because we evaluated all the relevant information provided by EASA and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. AD Requirements This AD requires initial and repetitive inspections of the IPC R1 blades, IPC R2 blades, and IPC shaft stage 2 dovetail posts, and removal of any cracked parts from service. Differences Between This AD and the MCAI or Service Information This AD requires inspections of any affected IPC part to be completed within 15 days of the effective date of this AD. EASA AD 2019–0075, dated March 29, 2019, requires inspection of certain affected IPC parts to be completed within 30 days of the effective date of EASA AD 2019–0075. The FAA expects most operators have already complied with EASA AD and find that completing the inspections within 15 days of the effective date of this AD provides an appropriate level of safety. Interim Action The FAA considers this AD interim action. The manufacturer is still reviewing this unsafe condition and may develop follow-on actions. FAA’s Justification and Determination of the Effective Date No domestic operators use this product. Therefore, the FAA finds that notice and opportunity for prior public comment are unnecessary and that good cause exists for making this amendment effective in less than 30 days. Comments Invited This AD is a final rule that involves requirements affecting flight safety, and the FAA did not provide you with notice and an opportunity to provide your comments before it becomes effective. However, the FAA invites you to send any written data, views, or arguments about this final rule. Send your comments to an address listed under the ADDRESSES section. Include the docket number FAA–2019–0528 and product identifier 2018–NE–24–AD at the beginning of your comments. The FAA specifically invites comments on the overall regulatory, economic, environmental, and energy aspects of this final rule. The FAA will consider all comments received by the closing date and may amend this final rule because of those comments. The FAA will post all comments we receive, without change, to https:// www.regulations.gov, including any personal information you provide. The FAA will also post a report summarizing each substantive verbal contact we receive about this final rule. Regulatory Flexibility Act The requirements of the Regulatory Flexibility Act (RFA) do not apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and comment. Because the FAA has determined that it has good cause to adopt this rule without notice and comment, RFA analysis is not required. Costs of Compliance The FAA estimates that this AD affects 0 engines installed on airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: jspears on DSK3GMQ082PROD with RULES ESTIMATED COSTS Action Labor cost Inspect IPC blades and dovetail posts ........... 20 work-hours × $85 per hour = $1700 .........

Authority for This Rulemaking List of Subjects in 14 CFR Part 39 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. The FAA is 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.

AGENCY: ACTION: The Federal Trade Commission (the ‘‘Commission’’) is amending its Telemarketing Sales Rule (‘‘TSR’’) by updating the fees charged to entities accessing the National Do Not Call Registry (the ‘‘Registry’’) as required by the Do-Not-Call Registry Fee Extension Act of 2007. DATES: This final rule (the revised fees) is effective October 1, 2019. ADDRESSES: Copies of this document are available on the internet at the Commission’s website: https:// www.ftc.gov. FOR FURTHER INFORMATION CONTACT: Ami Joy Dziekan (202–326–2648), Bureau of Consumer Protection, Federal Trade Commission, 600 Pennsylvania Avenue NW, Room CC–9225, Washington, DC 20580. SUPPLEMENTARY INFORMATION: To comply with the Do-Not-Call Registry Fee Extension Act of 2007 (Pub. L. 110–188, 122 Stat. 635) (‘‘Act’’), the Commission is amending the TSR by updating the SUMMARY: PO 00000 Frm 00006 Fmt 4700 Sfmt 4700 fees entities are charged for accessing the Registry as follows: The revised rule increases the annual fee for access to the Registry for each area code of data from $63 to $65 per area code; and increases the maximum amount that will be charged to any single entity for accessing area codes of data from $17,406 to $17,765. Entities may add area codes during the second six months of their annual subscription period, and the fee for those additional area codes of data remains $32. These increases are in accordance with the Act, which specifies that beginning after fiscal year 2009, the dollar amounts charged shall be increased by an amount equal to the amounts specified in the Act, multiplied by the percentage (if any) by which the average of the monthly consumer price index (for all urban consumers published by the Department of Labor) (‘‘CPI’’) for the most recently ended 12month period ending on June 30 exceeds the CPI for the 12-month period ending June 30, 2008. The Act also states that any increase shall be rounded to the nearest dollar and that there shall be no increase in the dollar amounts if the change in the CPI since the last fee increase is less than one percent. For fiscal year 2009, the Act specified that the original annual fee for access to the Registry for each area code of data was $54 per area code, or $27 per area code of data during the second six months of an entity’s annual subscription period, and that the maximum amount that would be charged to any single entity for accessing area codes of data would be $14,850. The determination whether a fee change is required and the amount of the fee change involves a two-step process. First, to determine whether a fee change is required, we measure the change in the CPI from the time of the previous increase in fees. There was an increase in the fees for fiscal year 2019. Accordingly, we calculated the change in the CPI since last year, and the increase was 2.07 percent. Because this change is over the one percent threshold, the fees will change for fiscal year 2020. Second, to determine how much the fees should increase this fiscal year, we use the calculation specified by the Act set forth above: The percentage change in the baseline CPI applied to the original fees for fiscal year 2009. The average value of the CPI for July 1, 2007 to June 30, 2008 was 211.702; the average value for July 1, 2018 to June 30, 2019 was 253.268, an increase of 19.63 percent. Applying the 19.63 percent increase to the base amount from fiscal year 2009, leads to a $65 fee for access E:\FR\FM\27AUR1.SGM 27AUR1

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: The FAA is superseding airworthiness directive (AD) 2018-25-01 
for all Rolls-Royce plc (RR) Trent 1000-A, Trent 1000-C, Trent 1000-D, 
Trent 1000-E, Trent 1000-G, and Trent 1000-H turbofan model engines. AD 
2018-25-01 required initial and repetitive inspections of the 
intermediate-pressure compressor (IPC) stage 1 rotor (R1) blades, IPC 
stage 2 rotor (R2) blades, and IPC shaft stage 2 dovetail posts, and 
removing any cracked parts from service. This AD retains those 
inspections, revises certain reinspection intervals, and adds certain 
engine models to the applicability. This AD was prompted by a 
determination by the manufacturer of the need to revise inspection 
intervals for certain affected engines. In addition, the FAA added 
recently validated additional engine models to the applicability. The 
FAA is issuing this AD to address the unsafe condition on these 
products.

DATES: This AD is effective September 11, 2019.
    The Director of the Federal Register approved the incorporation by

SUPPLEMENTARY INFORMATION:

Discussion

    The FAA issued AD 2018-25-01, Amendment 39-19511 (83 FR 62694, 
December 6, 2018), (``AD 2018-25-01''), for all RR Trent 1000-A, Trent 
1000-C, Trent 1000-D, Trent 1000-E, Trent 1000-G, and Trent 1000-H 
turbofan engine models. AD 2018-25-01 required initial inspections and 
repetitive inspections of the IPC R1 blades, IPC R2 blades, and IPC 
shaft stage 2 dovetail posts, and removal of any cracked parts from 
service. AD 2018-25-01 resulted from the manufacturer determining the 
need for repetitive inspections of the IPC R1 blades, IPC R2 blades, 
and IPC shaft stage 2 dovetail posts. The FAA issued AD 2018-25-01 to 
prevent failure of the IPC, which could result in failure of one or 
more engines, loss of thrust control, and loss of the airplane.

Actions Since AD 2018-25-01 Was Issued

    Since the FAA issued AD 2018-25-01, RR determined that inspection 
intervals for certain affected engines need to be revised. Also, since 
the FAA issued AD 2018-25-01, the European Union Aviation Safety Agency 
(EASA) has issued EASA AD 2019-0075, dated March 29, 2019 (``the 
MCAI''), which requires initial and repetitive inspections of IPC R1 
blades, IPC R2 blades, and IPC shaft stage 2 dovetail posts installed 
on certain engines and removal of any cracked parts from service.
    Also, since the FAA issued AD 2018-25-01, the type certificate (TC) 
for all Trent 1000 turbofan model engines was revised to add RR Trent 
1000-AE2 and Trent 1000-CE2 engine models to the list of applicable 
engine models. Both Trent 1000-AE2 and Trent 1000-CE2 engine models 
were identified in EASA AD 2019-0075 and are subject to the same unsafe 
condition as the other models listed in the Applicability of this AD.
    In addition, Rolls-Royce plc transferred TC E00076EN to Rolls-Royce 
Deutschland Ltd & Co KG (RRD) on February 21, 2019. The FAA has 
therefore revised the TC holder name from ``Rolls-Royce plc'' in AD 
2018-25-01 to ``Rolls-Royce Deutschland Ltd & Co KG'' in this AD. Where 
applicable, for example when referring to the relevant service 
information, the FAA continues to use the name ``Rolls-Royce plc'' in 
this AD.
    The FAA also updated our estimate for labor hours when replacing 
the IPC

[[Page 44684]]

blades and the IPC drum to be consistent with the estimates provided in 
the service information.
    The FAA is issuing this AD to address the unsafe condition on these 
products.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed RR Alert Non-Modification Service Bulletin (NMSB) 
Trent 1000 72-AK130, Revision 4, dated March 4, 2019, and RR NMSB Trent 
1000 72-K132, Revision 2, dated March 26, 2019. RR Alert NMSB Trent 
1000 72-AK130 describes procedures for performing initial and 
repetitive inspections of the IPC R1 blades, IPC R2 blades, and IPC 
shaft stage 2 dovetail posts, and lists engine serial numbers. RR NMSB 
Trent 1000 72-K132, describes procedures for replacement of the IPC R1 
blades, IPC R2 blades, and the IP compressor drum during refurbishment. 
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.

Other Related Service Information

    The FAA reviewed RR NMSB Trent 1000 72-K099, Revision 2, dated 
September 27, 2018, and earlier revisions; RR NMSB Trent 1000 72-K100, 
Initial Issue, dated June 11, 2018; RR NMSB Trent 1000 72-K129, Initial 
Issue, dated June 11, 2018; and RR NMSB Trent 1000 72-K129, Revision 3, 
dated February 28, 2019, and earlier revisions. RR NMSB Trent 1000 72-
K099, Initial Issue, and RR NMSB Trent 1000 72-K099, Revision 2, and 
earlier revisions, describe procedure for an ultrasonic inspection of 
the IPC R1 blades. RR NMSB Trent 1000 72-K100, Initial Issue, describes 
procedures for a visual borescope inspection of the IPC R2 blades and 
IPC shaft stage 2 dovetail posts. RR NMSB Trent 1000 72-K129, Revision 
3, and earlier revisions, describe procedures for an ultrasonic 
inspection of the IPC R2 blades.

FAA's Determination

    This product has been approved by EASA 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 EASA AD 2019-0075, dated March 29, 2019, and 
service information referenced above. The FAA is issuing this AD 
because we evaluated all the relevant information provided by EASA and 
determined the unsafe condition described previously is likely to exist 
or develop in other products of the same type design.

AD Requirements

    This AD requires initial and repetitive inspections of the IPC R1 
blades, IPC R2 blades, and IPC shaft stage 2 dovetail posts, and 
removal of any cracked parts from service.

Differences Between This AD and the MCAI or Service Information

    This AD requires inspections of any affected IPC part to be 
completed within 15 days of the effective date of this AD. EASA AD 
2019-0075, dated March 29, 2019, requires inspection of certain 
affected IPC parts to be completed within 30 days of the effective date 
of EASA AD 2019-0075. The FAA expects most operators have already 
complied with EASA AD and find that completing the inspections within 
15 days of the effective date of this AD provides an appropriate level 
of safety.

Interim Action

    The FAA considers this AD interim action. The manufacturer is still 
reviewing this unsafe condition and may develop follow-on actions.

FAA's Justification and Determination of the Effective Date

    No domestic operators use this product. Therefore, the FAA finds 
that notice and opportunity for prior public comment are unnecessary 
and that good cause exists for making this amendment effective in less 
than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and the FAA did not provide you with notice and an opportunity 
to provide your comments before it becomes effective. However, the FAA 
invites you to send any written data, views, or arguments about this 
final rule. Send your comments to an address listed under the ADDRESSES 
section. Include the docket number FAA-2019-0528 and product identifier 
2018-NE-24-AD at the beginning of your comments. The FAA specifically 
invites comments on the overall regulatory, economic, environmental, 
and energy aspects of this final rule. The FAA will consider all 
comments received by the closing date and may amend this final rule 
because of those comments.
    The FAA will post all comments we receive, without change, to 
https://www.regulations.gov, including any personal information you 
provide. The FAA will also post a report summarizing each substantive 
verbal contact we receive about this final rule.

Regulatory Flexibility Act

    The requirements of the Regulatory Flexibility Act (RFA) do not 
apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt 
a rule without prior notice and comment. Because the FAA has determined 
that it has good cause to adopt this rule without notice and comment, 
RFA analysis is not required.

Costs of Compliance

    The FAA estimates that this AD affects 0 engines installed on 
airplanes of U.S. registry.
    The FAA estimates the following costs to comply with this AD:

                                                 Estimated Costs

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

    The FAA estimates the following costs to do any necessary 
replacements that would be required based on the results of the 
inspection. The FAA has no way of determining the number of aircraft 
that might need these replacements:

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.
    The FAA is 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

    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 that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866, and
    (2) Will not affect intrastate aviation in Alaska.

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
