Download as PDF Federal Register / Vol. 82, No. 247 / Wednesday, December 27, 2017 / Rules and Regulations provided in § 1026.35(b)(2)(iii)(D)(1) and (2). Thus, the exemption applies, provided the other conditions of § 1026.35(b)(2)(iii) are satisfied, even if the creditor previously maintained escrow accounts for mortgage loans, provided it no longer maintains any such accounts except as provided in § 1026.35(b)(2)(iii)(D)(1) and (2). Once a creditor or its affiliate begins escrowing for loans currently serviced other than those addressed in § 1026.35(b)(2)(iii)(D)(1) and (2), however, the creditor and its affiliate become ineligible for the exemption in § 1026.35(b)(2)(iii) on higher-priced mortgage loans they make while such escrowing continues. Thus, as long as a creditor (or its affiliate) services and maintains escrow accounts for any mortgage loans, other than as provided in § 1026.35(b)(2)(iii)(D)(1) and (2), the creditor will not be eligible for the exemption for any higher-priced mortgage loan it may make. For purposes of § 1026.35(b)(2)(iii), a creditor or its affiliate ‘‘maintains’’ an escrow account only if it services a mortgage loan for which an escrow account has been established at least through the due date of the second periodic payment under the terms of the legal obligation. * * * * * Rolls-Royce Corporation (RRC) AE 3007A and AE 3007C model turbofan engines.

The NPRM published in the Federal Register on September 22, 2017 (82 FR 44357). The NPRM was prompted by an updated stress analysis that showed higher stress than previously calculated in the aft retainer flange scallop of the fan wheel, part number (P/N) 23061670. As a result, RRC reduced the published life of the affected fan wheel. The NPRM proposed to require removal of the affected fan wheel at new, lower life limits. We are issuing this AD to correct the unsafe condition on these products. Comments We gave the public the opportunity to participate in developing this final rule. We have considered the comment received. The Air Line Pilots Association supported the NPRM.

ACTION: Final rule; correcting amendments. AGENCY: In this final rule, the Bureau of Industry and Security corrects certain provisions in the Export Administration Regulations (EAR) to provide accurate references and fix typographical errors, and amend several Export Control Classification Numbers (ECCNs) to enhance consistency with the other ECCNs on the Commerce Control List (CCL). The corrections are editorial in nature and do not affect license requirements. SUMMARY: This rule is effective December 27, 2017. FOR FURTHER INFORMATION CONTACT: Ivan Mogensen, Office of Exporter Services, Bureau of Industry and Security, by telephone: (202) 482–2440 or email: Ivan.Mogensen@bis.doc.gov. SUPPLEMENTARY INFORMATION: daltland on DSKBBV9HB2PROD with RULES DATES: VerDate Sep<11>2014 18:49 Dec 26, 2017 Jkt 244001 Overview This final rule updates six parts of the EAR to correct typographical errors, clarify inaccurate or unclear internal references, and correct inconsistencies in certain entries on the Commerce Control List (CCL). Part 732 Section 732.4(b) discusses steps to be taken when reviewing license exceptions for exports and reexports. In § 732.4(b)(7)(ii), there is a reference to § 740.20(g) listing ECCNs that may be eligible for subsequent export or reexport under license exception STA, following submission of a license application. However, only ECCN 9A610.a is listed in § 732.4(b)(7)(ii), while ECCNs 0A606.a, 8A609.a, 8A620.a, 8A620.b, ‘‘spacecraft’’ in ECCN subparagraphs 9A515.a.1, a.2, a.3, a.4, 9A515.g, and 9E515.b, .d, .e, and .f (which also now appear in § 740.20(g)), are inadvertently omitted. This correction adds the omitted items listed in § 740.20(g) to § 732.4(b)(7)(ii). Additionally, because these items include both commodities and technology, the term ‘‘aircraft’’ in the reference to 9A610.a is replaced with ‘‘item.’’ This rule also clarifies and corrects the Export Control Decision Tree diagram in supplement No. 1 to part 732 that was last revised in a final rule published February 6, 2004 (69 FR 5686 (Feb. 6, 2004)). Several of the decision ‘‘blocks’’ in the flowchart contain references that are unclear or incorrect. This rule provides clarity by changing references to the general prohibitions to citations of specific sections of the EAR, and correcting improper citations to ensure that the citations contained in all decision blocks coincide with the appropriate sections of the EAR. Specifically, the changes are as follows: In the block which begins ‘‘Is your item classified under an ECCN on the CCL,’’ a direct citation to § 736.2(b)(1) through (3) replaces a reference to General Prohibitions 1 through 3, which did not inform the reader where the prohibitions could be found in the EAR; in the block which begins ‘‘Is there an ‘X’ in the box,’’ the EAR citations now directly follow references to the Commerce Country Chart and the CCL, respectively; and, in the block which begins ‘‘Use License Exception,’’ the citation to § 740.1, which is an introduction, is replaced with a reference to the whole of part 740. Additionally, several grammatical errors are addressed, and the section symbol (‘‘§ ’’) is added wherever a section of the EAR is referenced in the decision blocks PO 00000 Frm 00025 Fmt 4700 Sfmt 4700 61153 for clarity. Finally, this final rule changes the supplement’s name from ‘‘Decision Tree’’ to ‘‘Export Control Decision Tree’’ to match the title of the diagram, and the duplicative parenthetical in the graphic title reading ‘‘(Supp. No. 1 to Part 732)’’ is deleted. Part 734 Section 734.18 was created in the rule Revisions to Definitions in the Export Administration Regulations (81 FR 35586 (June 3, 2016)) and discusses activities that are not exports, reexports, or transfers. The note following the end of § 734.18(a)(5)(iv) discusses data in transit via the internet, but the note is incorrectly described as the note to paragraph (a)(4)(iv). This rule changes the note to refer to § 734.18(a)(5)(iv). Part 738 In § 738.2(d)(1), Composition of an entry, there is a description of the meaning attached to each alphanumeric character making up an Export Control Classification Number. This paragraph currently explains that the second ‘‘digit’’ in an ECCN indicates the ‘‘Reason for Control.’’ However, in paragraph (d)(1)(i) of this section, the paragraph refers to the Reason for Control as the third ‘‘digit.’’ This final rule amends § 738.2(d)(1)(i) to replace the word ‘‘digit’’ with ‘‘alphanumeric character’’ in order to maintain consistency and prevent confusion. Additionally, in § 738.2, this final rule makes a correction in § 738.2(d)(2)(iv)(C)(2). The text of this paragraph uses ECCN 2B992 as an example when providing an overview of how to read an ECCN heading on the Commerce Control List (CCL). However, in the latter part of the section, the text erroneously references ECCN 2B999 instead of 2B992. This rule replaces the reference to ECCN 2B999 with 2B992 in this section to correct the ECCN reference. Part 740 Section 740.20(g)(1) lists 9x515 and ‘‘600 series’’ ECCNs that are eligible for license exception Strategic Trade Authorization. This includes ECCNs 9A515.a.1, .a.2, .a.3, .a.4, and .g, 9A610.a, and technology ECCNs 9E515.b, .d, .e, and .f. In the final rule Revisions to the Export Administration Regulations (EAR): Control of Spacecraft Systems and Related Items the President Determines No Longer Warrant Control under the United States Munitions List (USML) (82 FR 2875 (Jan. 10, 2017)), the phrase ‘‘that provide space-based logistics, assembly or servicing of any spacecraft (e.g., refueling)’’ following the list of ECCN E:\FR\FM\27DER1.SGM 27DER1

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Rolls-Royce Corporation (RRC) AE 3007A and AE 3007C model turbofan 
engines. This AD was prompted by an updated analysis that lowered the 
life limit of fan wheels installed on the affected engines. This AD 
requires removal of the affected fan wheel at new, lower life limits. 
We are issuing this AD to address the unsafe condition on these 
products.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain RRC AE 3007A and AE 
3007C model turbofan engines. The NPRM published in the Federal 
Register on September 22, 2017 (82 FR 44357). The NPRM was prompted by 
an updated stress analysis that showed higher stress than previously 
calculated in the aft retainer flange scallop of the fan wheel, part 
number (P/N) 23061670. As a result, RRC reduced the published life of 
the affected fan wheel. The NPRM proposed to require removal of the 
affected fan wheel at new, lower life limits. We are issuing this AD to 
correct the unsafe condition on these products.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. We have considered the comment received. The Air Line 
Pilots Association supported the NPRM.

Conclusion

    We reviewed the relevant data, considered the comment received, and 
determined that air safety and the public interest require adopting 
this final rule as proposed except for minor editorial changes. We have 
determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    We reviewed RRC Alert Service Bulletin (ASB) AE 3007A-A-72-424/ASB 
AE 3007C-A-72-327 (one document), Revision 1, dated April 20, 2017. The 
ASB provides updated life limits for the affected fan wheels. 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.

Costs of Compliance

    We estimate that this AD affects 341 engines installed on airplanes 
of U.S. registry.
    We estimate 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.
    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

    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,
    (2) Is not a ``significant rule'' under DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979),
    (3) Will not affect intrastate aviation in Alaska, and
