In particular, the Bureau invites the public, including consumers and their advocates, housing counselors, mortgage loan servicers and other industry representatives, industry analysts, and other interested persons to submit the following: (1) Comments on the feasibility and effectiveness of the assessment plan, the objectives of the 2013 RESPA Servicing Rule that the Bureau intends to emphasize in the assessment, and the outcomes, metrics, baselines, and analytical methods for assessing the effectiveness of the rule as described in part IV above; (2) Data and other factual information that may be useful for executing the Bureau’s assessment plan, 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 execute any recommended improvements to the assessment plan; (4) Data and other factual information about the benefits and costs of the rule for consumers, servicers, and others in the mortgage industry; and about the effects of the rule on transparency, efficiency, access, and innovation in the mortgage market; (5) 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; and (6) Recommendations for modifying, expanding or eliminating the 2013 RESPA Servicing Rule. V. Request for Comment To inform the assessment, the Bureau hereby invites members of the public to submit information and other comments relevant to the issues identified below, as well as any information relevant to assessing the effectiveness of the 2013 RESPA Servicing Rule in meeting the purposes and objectives of title X of the Dodd-Frank Act (section 1021) and the specific goals of the Bureau (enumerated pmangrum on DSK3GDR082PROD with PROPOSALS other than the rule itself may affect observable outcomes. The Bureau has data sources, currently available or in development, with which to undertake these analyses, and the Bureau is also planning to secure additional data. These data sources include the National Mortgage Database (NMDB) and the American Survey of Mortgage Borrowers (ASMB),24 data from consumer complaints submitted to the Bureau, servicing data from a private vendor, and applicable information obtained from Bureau supervision and enforcement activities. The Bureau is also exploring the availability and utility of other sources of administrative data for conducting the assessment. The Bureau intends to seek input from housing counselors, legal aid attorneys, and mortgage servicers as it analyzes the data described above and interprets the findings. The Bureau is also seeking to obtain deidentified loanlevel data from a small number of servicers. This would potentially allow the Bureau to correlate mandated servicer activity (e.g., the early intervention requirements of the 2013 RESPA Servicing Rule) with consumer activity (e.g., additional consumer payments or additional loss mitigation applications occurring shortly after early intervention communications). It would also potentially allow the Bureau to correlate consumer and servicer activity with the measures of immediate consumer outcomes discussed earlier (fees and charges, delinquency resolution, time to resolution). Dated: April 29, 2017. Richard Cordray, Director, Bureau of Consumer Financial Protection. 24 The NMDB and the ASMB are multi-year projects being jointly undertaken by the Federal Housing Finance Agency (FHFA) and the Bureau.

Discussion pmangrum on DSK3GDR082PROD with PROPOSALS EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD No. 2015– 0016, dated January 30, 2015, to correct an unsafe condition for Airbus Model AS 332 L2 and EC 225 LP helicopters with certain part-numbered attachment pins installed. EASA advises of three cracked attachment pins on a Model AS 332 L2 helicopter. According to EASA, the cracks resulted from a combination of factors including corrosion that had initiated in the inner diameter area of the attachment pin chamfer. EASA states that if this condition is not detected and corrected, it may lead to failure of the attachment pin with loss of control of the helicopter. Due to design similarity, Model EC225LP helicopters are also affected by this issue. For these reasons, EASA AD No. 2015–0016 requires repetitive inspections of the attachment pins for corrosion. FAA’s Determination These helicopters have been approved by the aviation authority of France and are approved for operation in the United States. Pursuant to our bilateral agreement with France, EASA, its technical representative, has notified us of the unsafe condition described in its VerDate Sep<11>2014 14:38 May 10, 2017 Jkt 241001 AD. We are proposing this AD because we evaluated all known relevant information and determined that an unsafe condition is likely to exist or develop on other products of these same type designs. Related Service Information Under 1 CFR Part 51 We reviewed Airbus Helicopters Alert Service Bulletin (ASB) No. AS332– 05.00.99, Revision 0, dated December 22, 2014 (AS332–05.00.99), for Model AS332L2 helicopters and Airbus Helicopters ASB No. EC225–05A040, Revision 0, dated December 22, 2014 (EC225–05A040), for Model EC225LP helicopters. Airbus Helicopters advises of cracks discovered in attachment pins that resulted from a combination of factors, but mainly corrosion which initiated in the inner diameter at the chamfer. This service information specifies repetitively inspecting for corrosion and cracks and ensuring there are no corrosion pits in the attachment pins. If there is corrosion, this service information allows an attachment pin to be reworked up to four times before removing it from service. If there is a crack, this service information specifies contacting and sending the attachment pin to Airbus Helicopters. 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. Proposed AD Requirements This proposed AD would require an initial and recurring inspection of each attachment pin for corrosion, a crack, and any pitting. If there is a crack or any pitting, this proposed AD would require replacing the attachment pin. If there is corrosion, this proposed AD would require removing the corrosion up to a maximum of four times. This proposed AD would also require performing these inspections prior to installing an attachment pin. Differences Between This Proposed AD and the EASA AD The EASA AD does not require an inspection of the protective coating of each attachment pin for Model EC225LP helicopters. This proposed AD would require inspecting the protective coating of each attachment pin for both model helicopters. The EASA AD requires ensuring there are no corrosion pits without a corresponding corrective action. This proposed AD would require replacing an attachment pin that has any pitting. The EASA AD requires a non-destructive inspection if in doubt about whether there is a crack, while PO 00000 Frm 00006 Fmt 4702 Sfmt 4702 21957 this proposed AD would not. Lastly, the EASA AD requires contacting and returning to Airbus Helicopters any attachment pin with a crack, and this proposed AD would not. Costs of Compliance We estimate that this proposed AD would affect 5 helicopters of U.S. Registry. We estimate that operators may incur the following costs in order to comply with this proposed AD. Labor costs are estimated at $85 per workhour. For Model AS332L2 helicopters, there would be no costs of compliance with this proposed AD because there are no helicopters with this type certificate on the U.S. Registry. For Model EC225LP helicopters, which have ten attachment pins installed, inspecting the attachment pins would take about 1 work-hour for a total cost of $85 per helicopter and $425 for the U.S. fleet. Removing corrosion would take about 1 work-hour for a total cost of $85 per attachment pin. Replacing an attachment pin would take negligible additional labor time and required parts would cost about $5,720. 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. 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, I certify this proposed regulation: E:\FR\FM\11MYP1.SGM 11MYP1 21958 Federal Register / Vol. 82, No. 90 / Thursday, May 11, 2017 / Proposed Rules 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 to the extent that it justifies making a regulatory distinction; 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. We prepared an economic evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket.

Discussion

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD No. 2015-0016, dated January 30, 
2015, to correct an unsafe condition for Airbus Model AS 332 L2 and EC 
225 LP helicopters with certain part-numbered attachment pins 
installed. EASA advises of three cracked attachment pins on a Model AS 
332 L2 helicopter. According to EASA, the cracks resulted from a 
combination of factors including corrosion that had initiated in the 
inner diameter area of the attachment pin chamfer. EASA states that if 
this condition is not detected and corrected, it may lead to failure of 
the attachment pin with loss of control of the helicopter. Due to 
design similarity, Model EC225LP helicopters are also affected by this 
issue.
    For these reasons, EASA AD No. 2015-0016 requires repetitive 
inspections of the attachment pins for corrosion.

FAA's Determination

    These helicopters have been approved by the aviation authority of 
France and are approved for operation in the United States. Pursuant to 
our bilateral agreement with France, EASA, its technical 
representative, has notified us of the unsafe condition described in 
its AD. We are proposing this AD because we evaluated all known 
relevant information and determined that an unsafe condition is likely 
to exist or develop on other products of these same type designs.

Related Service Information Under 1 CFR Part 51

    We reviewed Airbus Helicopters Alert Service Bulletin (ASB) No. 
AS332-05.00.99, Revision 0, dated December 22, 2014 (AS332-05.00.99), 
for Model AS332L2 helicopters and Airbus Helicopters ASB No. EC225-
05A040, Revision 0, dated December 22, 2014 (EC225-05A040), for Model 
EC225LP helicopters. Airbus Helicopters advises of cracks discovered in 
attachment pins that resulted from a combination of factors, but mainly 
corrosion which initiated in the inner diameter at the chamfer. This 
service information specifies repetitively inspecting for corrosion and 
cracks and ensuring there are no corrosion pits in the attachment pins. 
If there is corrosion, this service information allows an attachment 
pin to be reworked up to four times before removing it from service. If 
there is a crack, this service information specifies contacting and 
sending the attachment pin to Airbus Helicopters.
    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.

Proposed AD Requirements

    This proposed AD would require an initial and recurring inspection 
of each attachment pin for corrosion, a crack, and any pitting. If 
there is a crack or any pitting, this proposed AD would require 
replacing the attachment pin. If there is corrosion, this proposed AD 
would require removing the corrosion up to a maximum of four times. 
This proposed AD would also require performing these inspections prior 
to installing an attachment pin.

Differences Between This Proposed AD and the EASA AD

    The EASA AD does not require an inspection of the protective 
coating of each attachment pin for Model EC225LP helicopters. This 
proposed AD would require inspecting the protective coating of each 
attachment pin for both model helicopters. The EASA AD requires 
ensuring there are no corrosion pits without a corresponding corrective 
action. This proposed AD would require replacing an attachment pin that 
has any pitting. The EASA AD requires a non-destructive inspection if 
in doubt about whether there is a crack, while this proposed AD would 
not. Lastly, the EASA AD requires contacting and returning to Airbus 
Helicopters any attachment pin with a crack, and this proposed AD would 
not.

Costs of Compliance

    We estimate that this proposed AD would affect 5 helicopters of 
U.S. Registry. We estimate that operators may incur the following costs 
in order to comply with this proposed AD. Labor costs are estimated at 
$85 per work-hour.
    For Model AS332L2 helicopters, there would be no costs of 
compliance with this proposed AD because there are no helicopters with 
this type certificate on the U.S. Registry.
    For Model EC225LP helicopters, which have ten attachment pins 
installed, inspecting the attachment pins would take about 1 work-hour 
for a total cost of $85 per helicopter and $425 for the U.S. fleet. 
Removing corrosion would take about 1 work-hour for a total cost of $85 
per attachment pin. Replacing an attachment pin would take negligible 
additional labor time and required parts would cost about $5,720.

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.

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, I certify this proposed regulation:

[[Page 21958]]

    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 to the extent that 
it justifies making a regulatory distinction; 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.
    We prepared an economic evaluation of the estimated costs to comply 
with this proposed AD and placed it in the AD docket.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13   [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

Airbus Helicopters: Docket No. FAA-2017-0419; Directorate Identifier 
2015-SW-077-AD.

(a) Applicability

    This AD applies to the following helicopters, certificated in 
any category:
    (1) Model AS332L2 helicopters with a main rotor (M/R) blade 
attachment pin (attachment pin) part number (P/N) 332A31-2123-00 or 
P/N 332A31-2115-20 installed; and
    (2) Model EC225LP helicopters with an attachment pin P/N 332A31-
3204-20 installed.

(b) Unsafe Condition

    This AD defines the unsafe condition as corrosion or a crack in 
an attachment pin. This condition could result in loss of an M/R 
blade and subsequent loss of control of the helicopter.

(c) Comments Due Date

    We must receive comments by July 10, 2017.

(d) Compliance

    You are responsible for performing each action required by this 
AD within the specified compliance time unless it has already been 
accomplished prior to that time.

(e) Required Actions

    (1) For Model AS332L2 helicopters, within 410 hours time-in-
service (TIS), and for Model EC225LP helicopters within 660 hours 
TIS, remove each attachment pin and inspect the protective coating 
on the inside of the attachment pin for scratches and missing 
protective coating.
    (i) If there is a scratch or any missing protective coating, 
sand the attachment pin to remove the varnish in the area depicted 
as ``Area A'' in Figure 1 of Airbus Helicopters Alert Service 
Bulletin (ASB) No. AS332-05.00.99, Revision 0, dated December 22, 
2014 (AS332-05.00.99), or Airbus Helicopters ASB No. EC225-05A040, 
Revision 0, dated December 22, 2014 (EC225-05A040), as applicable to 
your model helicopter.
    (ii) Using a 10X or higher power magnifying glass, inspect for 
corrosion and pitting at the chamfer. An example of pitting is shown 
in the Accomplishment Instructions, paragraph 3.B.3., Note 1, of 
AS332-05.00.99, and paragraph 3.B.2., Note 1, of EC225-05A040. If 
there is any corrosion, remove the corrosion. If there is any 
pitting, replace the attachment pin. Do not sand the attachment pin 
to remove a corrosion pit.
    (iii) Using a 10X or higher power magnifying glass, inspect the 
inside and outside of the attachment pin for a crack in the areas 
depicted as ``Area A'' and ``Area B'' in Figure 1 of AS332-05.00.99 
or EC225-05A040, as applicable to your model helicopter. Pay 
particular attention to the chamfer in ``Area A.'' If there is a 
crack, remove the attachment pin from service.
    (2) Thereafter, for Model AS332L2 helicopters, at intervals not 
to exceed 825 hours TIS or 26 months, whichever occurs first; and 
for Model EC225LP helicopters, at intervals not to exceed 1,320 
hours TIS or 26 months, whichever occurs first; perform the actions 
specified in paragraph (e)(1) of this AD. Corrosion may be removed 
from an attachment pin as specified in paragraph (e)(1)(ii) of this 
AD a maximum of four times. If there is a fifth occurrence of 
corrosion on an attachment pin, before further flight, remove the 
attachment pin from service.
    (3) Do not install an attachment pin P/N 332A31-2123-00, P/N 
332A31-2115-20, or P/N 332A31-3204-20 on any helicopter unless you 
have complied with the actions in paragraph (e)(1) of this AD.

(f) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Safety Management Group, FAA, may approve AMOCs
