SUPPLEMENTARY INFORMATION: jbell on DSK3GLQ082PROD with RULES Discussion The FAA learned of five commanded IFSD events that occurred on certain CFM LEAP–1B model turbofan engines beginning in August 2018. CFM’s investigations identified debris on the TGB scavenge screen, A-sump screen, VerDate Sep<11>2014 16:08 Jun 17, 2019 Jkt 247001 and other screens. Subsequently, CFM determined that these IFSD events were the result of inadequate oil flow to the RDS bearing, which caused the RDS bearing cage to fail. This condition, if not addressed, could result in failure of one or more engines, loss of thrust control, and loss of the airplane. 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 CFM Service Bulletin (SB) LEAP–1B–72–00–0222– 01A–930A–D, Issue 007, dated May 17, 2019. The SB describes procedures for inspections of TGB scavenge screens and borescope inspection (BSI) of the RDS bearing. 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 CFM SB LEAP– 1B–72–00–0256–01A–930A–D, Issue 003, dated May 17, 2019. The SB describes procedures for an optional BSI of the RDS bearing. CFM has cancelled this SB and transferred its content to CFM SB LEAP–1B–72–00–0222–01A– 930A–D, Issue 007, dated May 17, 2019. FAA’s Determination The FAA is issuing this AD because it 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. AD Requirements This AD requires initial and repetitive inspections of the TGB scavenge screens and, depending on the results of the inspection, possible removal of the engine from service. Interim Action The FAA considers this AD interim action. The manufacturer is currently developing a modification that will address the unsafe condition identified in this AD. Once this modification is developed, approved, and available, the FAA might consider additional rulemaking. FAA’s Justification and Determination of the Effective Date An unsafe condition exists that requires the immediate adoption of this AD without providing an opportunity for public comments prior to adoption. The FAA has found that the risk to the flying public justifies waiving notice PO 00000 Frm 00033 Fmt 4700 Sfmt 4700 28203 and comment prior to adoption of this rule. The affected CFM LEAP–1B model turbofan engines experienced multiple RDS bearing cage failures in the last five months resulting in five IFSDs. The TGB scavenge screens must be inspected before accumulating between 100–250 flight hours since new on the RDS bearing or within 50 FHs after the effective date of this AD to prevent the failure of the RDS bearing, which could lead to in-flight shutdown of both engines, loss of thrust control, and loss of the airplane. Therefore, the FAA finds good cause that notice and opportunity for prior public comment are impracticable. In addition, for the reason stated above, the FAA finds 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 was not preceded by notice and an opportunity for public comment. 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–2019–0414 and Product Identifier 2019–NE–15–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 received, 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 received 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 136 engines installed on airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: E:\FR\FM\18JNR1.SGM 18JNR1 28204 Federal Register / Vol. 84, No. 117 / Tuesday, June 18, 2019 / Rules and Regulations ESTIMATED COSTS Action Labor cost Inspect TGB scavenge screens ............................. 1 work-hour × $85 per hour = $85 ......... jbell on DSK3GLQ082PROD with RULES 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.

ACTION: Final rule. AGENCY: SUMMARY: The Consumer Product Safety Improvement Act of 2008 (CPSIA) requires the United States Consumer Product Safety Commission (CPSC) to adopt safety standards for durable infant or toddler products. To comply with the CPSIA, the Commission is issuing a safety standard for stationary activity centers (SACs). This rule incorporates by reference ASTM F2012–18ε1, Standard Consumer Safety Performance Specification for Stationary Activity Centers (ASTM F2012–18ε1). This rule also amends the regulations for third party conformity assessment bodies to include the safety standard for SACs in the list of notices of requirements (NORs). DATES: The rule will become effective on December 18, 2019. The incorporation by reference of the publication listed in this rule is approved by the Director of the Federal Register as of December 18, 2019. PO 00000 Frm 00035 Fmt 4700 Sfmt 4700 28205 FOR FURTHER INFORMATION CONTACT: Keysha Walker, Office of Compliance and Field Operations, U.S. Consumer Product Safety Commission; 4330 EastWest Highway, Bethesda, MD 20814; telephone: (301) 504–6820; email: KWalker@cpsc.gov. SUPPLEMENTARY INFORMATION: I. Background and Statutory Authority Congress enacted the CPSIA (Pub. L. 110–314, 122 Stat. 3016), including the Danny Keysar Child Product Safety Notification Act, on August 14, 2008. Section 104(b) of the CPSIA requires the Commission to: (1) Examine and assess the effectiveness of voluntary consumer product safety standards for durable infant or toddler products, in consultation with representatives of consumer groups, juvenile product manufacturers, and independent child product engineers and experts; and (2) issue consumer product safety standards for durable infant or toddler products. 15 U.S.C. 2056a(b)(1). Any standard the Commission adopts under this mandate must be ‘‘substantially the same as’’ the voluntary standard, or more stringent than the voluntary standard if the Commission determines that more stringent requirements would further reduce the risk of injury associated with the product. Id. Section 104(f)(1) of the CPSIA defines the term ‘‘durable infant or toddler product’’ as ‘‘a durable product intended for use, or that may be reasonably expected to be used, by children under the age of 5 years,’’ and lists SACs as a durable infant or toddler product. Id. 2056a(f). On June 19, 2018, the Commission issued a notice of proposed rulemaking (NPR), proposing to incorporate by reference the voluntary standard for SACs, ASTM F2012–18ε1, without modifications. 83 FR 28390. ASTM F2012–18ε1 is still the current version of the standard. In this final rule, the Commission incorporates by reference ASTM F2012– 18ε1, with no modifications, as the mandatory safety standard for SACs. CPSC staff consulted with manufacturers, retailers, trade organizations, laboratories, consumer advocacy groups, consultants, and the public to develop this standard, largely through the ASTM standarddevelopment process. In addition, this final rule amends the list of NORs in 16 CFR part 1112 to include the standard for SACs. This rule is based on information in CPSC staff’s briefing package, ‘‘Staff’s Draft Final Rule for Stationary Activity Centers Under the Danny Keysar Child Product Safety Notification Act,’’ which is available on CPSC’s website.

SUPPLEMENTARY INFORMATION:

Discussion

    The FAA learned of five commanded IFSD events that occurred on 
certain CFM LEAP-1B model turbofan engines beginning in August 2018. 
CFM's investigations identified debris on the TGB scavenge screen, A-
sump screen, and other screens. Subsequently, CFM determined that these 
IFSD events were the result of inadequate oil flow to the RDS bearing, 
which caused the RDS bearing cage to fail. This condition, if not 
addressed, could result in failure of one or more engines, loss of 
thrust control, and loss of the airplane. 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 CFM Service Bulletin (SB) LEAP-1B-72-00-0222-01A-
930A-D, Issue 007, dated May 17, 2019. The SB describes procedures for 
inspections of TGB scavenge screens and borescope inspection (BSI) of 
the RDS bearing. 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 CFM SB LEAP-1B-72-00-0256-01A-930A-D, Issue 003, 
dated May 17, 2019. The SB describes procedures for an optional BSI of 
the RDS bearing. CFM has cancelled this SB and transferred its content 
to CFM SB LEAP-1B-72-00-0222-01A-930A-D, Issue 007, dated May 17, 2019.

FAA's Determination

    The FAA is issuing this AD because it 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.

AD Requirements

    This AD requires initial and repetitive inspections of the TGB 
scavenge screens and, depending on the results of the inspection, 
possible removal of the engine from service.

Interim Action

    The FAA considers this AD interim action. The manufacturer is 
currently developing a modification that will address the unsafe 
condition identified in this AD. Once this modification is developed, 
approved, and available, the FAA might consider additional rulemaking.

FAA's Justification and Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD without providing an opportunity for public comments prior to 
adoption. The FAA has found that the risk to the flying public 
justifies waiving notice and comment prior to adoption of this rule. 
The affected CFM LEAP-1B model turbofan engines experienced multiple 
RDS bearing cage failures in the last five months resulting in five 
IFSDs. The TGB scavenge screens must be inspected before accumulating 
between 100-250 flight hours since new on the RDS bearing or within 50 
FHs after the effective date of this AD to prevent the failure of the 
RDS bearing, which could lead to in-flight shutdown of both engines, 
loss of thrust control, and loss of the airplane. Therefore, the FAA 
finds good cause that notice and opportunity for prior public comment 
are impracticable. In addition, for the reason stated above, the FAA 
finds 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 was not preceded by notice and an opportunity for public 
comment. 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-
0414 and Product Identifier 2019-NE-15-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 received, 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 received 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 136 engines installed on 
airplanes of U.S. registry.
    The FAA estimates the following costs to comply with this 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.
    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.
