Download as PDF Federal Register / Vol. 84, No. 226 / Friday, November 22, 2019 / Proposed Rules members of the general public and regulated entities.41 The comments the Bureau received in response to the Guidance RFI highlight the importance of guidance and compliance aids for regulatory implementation, specifically for implementing highly technical rules such as the TRID Rule.42 They also highlighted certain aspects of guidance that were not addressed or guidance styles that did not work well such as providing more guidance on what requirements of the TRID Rule apply to different segments of the market and providing specific examples to facilitate compliance. For assessment purposes of the TRID Rule, the Bureau is interested in learning more about any aspects of the Rule that were confusing or on which more guidance was needed, whether at the time the Rule took effect or afterwards, and the effects of this confusion or lack of guidance (including any unintended effects on market liquidity in any sectors of the housing finance system). Request for Comment The Bureau hereby invites members of the public to submit information and other comments relevant to the issues identified above and below, information relevant to enumerating costs and benefits of the TRID Rule to inform the assessment’s cost-benefit perspective, and any other information relevant to assessing the effectiveness of the TRID Rule in meeting the purposes and objectives of title X of the Dodd-Frank Act (section 1021) and the specific goals of the Bureau. In particular, the Bureau invites the public, including consumers and their advocates, housing counselors, mortgage creditors, settlement agents, and other industry participant, industry analysts, and other interested persons to submit comments on any or all of the following: (1) Comments on the feasibility and effectiveness of the assessment plan, the objectives of the TRID Rule that the Bureau intends to use in the assessment, and the outcomes, metrics, baselines, and analytical methods for assessing the effectiveness of the Rule as described in part IV above; khammond on DSKJM1Z7X2PROD with PROPOSALS 41 For the full electronic docket, see https:// www.regulations.gov/docket?D=CFPB-2018-0013. The Bureau received approximately 49 comments on this RFI (42 that addressed the substance of the RFI). The Bureau received a number of comments related to guidance but for the purpose of the TRID assessment, only comments received related to TRID guidance are mentioned. 42 The Bureau continues to update and improve its regulatory guidance and implementation aids. Several materials were, and will be, published after the implementation of the TRID Rule to provide more guidance and clarity, and the Bureau continues to work to identify and address additional guidance needs. VerDate Sep<11>2014 15:57 Nov 21, 2019 Jkt 250001 (2) Data and other factual information that the Bureau may find useful in executing its assessment plan and answering related research questions, particularly research questions that may be difficult to address with the data currently available to the Bureau, as described in part IV above; (3) Recommendations to improve the assessment plan, as well as data, other factual information, and sources of data that would be useful and available to the Bureau to execute any recommended improvements to the assessment plan; (4) Data and other factual information about the benefits and costs of the TRID Rule for consumers, creditors, or other stakeholders; (5) Data and other factual information about the effects of the Rule on transparency, efficiency, access, and innovation in the mortgage market; (6) Data and other factual information about the Rule’s effectiveness in meeting the purposes and objectives of title X of the Dodd-Frank Act (section 1021), which are listed in part IV above; (7) Data and other factual information on the disclosure dataset specified in the Assessing Firm Effects section above under part IV; (8) Comments on any aspects of the TRID Rule that were or are confusing or on which more guidance was or is needed during implementation including whether the issues have been resolved or remain unresolved; and (9) Recommendations for modifying, expanding, or eliminating the TRID Rule.

The FAA will also post a report summarizing each substantive verbal contact received about this NPRM. Discussion The FAA received several reports of failures of the affected LPT 3rd-stage blades. These failures appear to be caused by debris passing through the engine. The manufacturer has determined the need to replace any affected LPT 3rd-stage blade with an LPT blade made of a different material that is less susceptible to impact damage. This condition, if not addressed, could result in uncontained release of the LPT 3rd-stage blades, failure of one or more engines, loss of thrust control, and loss of the airplane. Related Service Information The FAA reviewed Pratt & Whitney Service Bulletin PW1000G–C–72–00– 0111–00A–930A–D, Issue No. 002, dated October 18, 2019. The service information describes procedures for removal of the affected LPT 3rd-stage blades and their replacement with parts eligible for installation. FAA’s Determination The FAA is proposing this AD because the Agency 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 removal from service of LPT 3rd-stage blades part/number (P/N) 5387343, 5387493, 5387473, or 5387503, and their replacement with parts eligible for installation. Costs of Compliance The FAA estimates that this proposed AD affects 65 engines installed on airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: ESTIMATED COSTS Labor cost Parts cost Replace set of LPC 3rd-stage blades .. 0 work-hours × $85 per hour = $0 ....... $750,000 per blade set ...... Authority for This Rulemaking khammond on DSKJM1Z7X2PROD with PROPOSALS Cost per product Action 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 VerDate Sep<11>2014 15:57 Nov 21, 2019 Jkt 250001 applicable to engines, propellers, and associated appliances to the Manager, Engine and Propeller Standards Branch, Policy and Innovation Division. Regulatory Findings The FAA 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, the FAA certifies this proposed regulation: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, (2) Will not affect intrastate aviation in Alaska, and (3) 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.

Discussion

    The FAA received several reports of failures of the affected LPT 
3rd-stage blades. These failures appear to be caused by debris passing 
through the engine. The manufacturer has determined the need to replace 
any affected LPT 3rd-stage blade with an LPT blade made of a different 
material that is less susceptible to impact damage. This condition, if 
not addressed, could result in uncontained release of the LPT 3rd-stage 
blades, failure of one or more engines, loss of thrust control, and 
loss of the airplane.

Related Service Information

    The FAA reviewed Pratt & Whitney Service Bulletin PW1000G-C-72-00-
0111-00A-930A-D, Issue No. 002, dated October 18, 2019. The service 
information describes procedures for removal of the affected LPT 3rd-
stage blades and their replacement with parts eligible for 
installation.

FAA's Determination

    The FAA is proposing this AD because the Agency 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 removal from service of LPT 3rd-
stage blades part/number (P/N) 5387343, 5387493, 5387473, or 5387503, 
and their replacement with parts eligible for installation.

Costs of Compliance

    The FAA estimates that this proposed AD affects 65 engines 
installed on airplanes of U.S. registry.
    The FAA estimates 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.
    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

    The FAA 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, the FAA certifies this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Will not affect intrastate aviation in Alaska, and
    (3) 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.

(e) Unsafe Condition

    This AD was prompted by reports of failure of certain LPT 3rd-
stage blades. The FAA is issuing this AD to prevent failure of these 
LPT 3rd-stage blades. The unsafe condition, if not addressed, could 
result in uncontained release of the LPT 3rd-stage blades, failure 
of one or more engines, loss of thrust control, and loss of the 
airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Required Actions

    At the next engine shop visit after the effective date of this 
AD, remove from service any LPT 3rd-stage blade, P/N 5387343, 
5387493, 5387473, or 5387503, and replace with a part eligible for 
installation.

(h) Definitions

    (1) For the purpose of this AD, an ``engine shop visit'' is the 
induction of an engine into the shop for maintenance involving the 
separation of pairs of major mating engine flanges, except that the 
separation of engine flanges solely for the purposes of 
transportation of the engine without subsequent engine maintenance 
does not constitute an engine shop visit.
    (2) For the purpose of this AD, a ``part eligible for 
installation'' is any LPT 3rd-stage blade that does not have a P/N 
5387343, 5387493, 5387473, or 5387503.

(i) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, ECO Branch, FAA, has the authority to approve 
AMOCs for this AD, if requested using the procedures found in 14 CFR 
39.19. In accordance with 14 CFR 39.19, send your request to your 
principal inspector or local Flight Standards District Office, as 
appropriate. If sending information directly to the manager of the 
certification office, send it to the attention of the person 
identified in paragraph (j)(1) of this AD. You may email your 
request to: [email protected].
    (2) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager
