26An open-loop card usually carries the logo of 

a major payment network, such as American 

Express, Discover, MasterCard, or Visa, and can be 

used wherever those cards are accepted. 

27A closed-loop card usually can be used only at 

one store, chain of stores, or group of stores (such 

as stores in a shopping mall). See Act § 1002(28)(B) 

(setting forth exclusion for certain closed-loop 

cards). 

28Electronic benefits transfer cards are made 

available by the Federal government and by state 

and local governments to allow individuals to 

access government benefits such as Social Security 

or unemployment compensation. 

29Payroll cards are made available by employers 

to employees to access their salaries.

33Principally, these providers offer to reduce 

consumers’ credit card debt, but some providers 

offer to reduce medical or tax debt. Not included 

in the debt relief market are providers of debt relief 

services that relate to mortgage debt, commonly 

referred to as mortgage loan modification or 

foreclosure relief services. Section 1024(a)(1)(A) 

and (b) of the Act gives the CFPB authority to 

supervise those providers without regard to size.

and brokers. Relevant products include, 

for example, secured credit such as 

automobile loans, and unsecured 

consumer installment loans. Revenues 

in auto lending and financing, and other 

sales financing, total $60 billion 

annually.23 The CFPB’s authority 

relating to consumer credit providers is 

subject to important exceptions in the 

Act, including exceptions relating to 

vehicle dealerships and retailers and 

merchants.24 The CFPB will need to 

consider carefully how the respective 

consumer credit-related product and 

service markets should be defined. 

D. Money Transmitting, Check Cashing, 

and Related Activities 

Money transmitting generally 

involves the receipt of funds by a 

transmitter that then sends the funds via 

wire transfer, ACH transfer, or other 

means to a recipient in another location 

on behalf of a consumer, for a fee. The 

check cashing business generally 

involves the cashing of consumer 

checks by retail establishments for a fee. 

The sale of money orders and related 

items provides products consumers can 

use to pay bills or conduct other 

financial transactions. Typically, 

businesses engaged in the foregoing 

activities offer a menu of several of 

these products and services to 

consumers. 

Money transmitting is a significant 

industry. Total transaction volume for 

money transmission was approximately 

$72 billion in 2005, with $40 billion of 

that amount transmitted 

internationally.25 The CFPB will need to 

consider whether to include money 

transmitting alone, or money 

transmitting and related consumer 

financial products and services such as 

check cashing, as a market or markets to 

be covered in an initial rule. If multiple 

products are included, the CFPB will 

need to consider carefully how the 

respective product and service markets 

should be defined. 

E. Prepaid Cards 

A prepaid card product is one in 

which funds are paid into an individual 

or pooled account by, or on behalf of, 

a consumer and can be accessed by the 

consumer via a card (and in some cases, 

by alternative means). Prepaid card 

products include general purpose 

reloadable open-loop payment cards,26

non-reloadable open loop payment 

cards, closed-loop gift or store cards,27

electronic benefits transfer cards,28 and 

payroll cards.29 Multiple parties may be 

involved in offering or providing a 

prepaid card product. However, under 

the Act, the definition of ‘‘consumer 

financial product or service’’ would not 

include the sale or reloading of prepaid 

cards by persons that do not exercise 

‘‘substantial control’’ over the terms or 

conditions of the stored value provided 

to the consumer.30

Prepaid card products affect a large 

number of consumers. Over $140 billion 

dollars in transactions were made with 

reloadable open-loop prepaid cards in 

2009.31 Over 11 million households 

have used these cards.32 The CFPB will 

need to consider carefully whether to 

cover all or only certain types of prepaid 

card products in an initial rule, and, for 

those included, how to define the 

relevant market or markets. 

F. Debt Relief Services 

Debt relief services refer to consumer 

financial products and services offered 

to reduce a consumer’s debt.33 Providers 

generally offer one of two products or 

services.34 Providers of ‘‘debt 

management plans,’’ typically nonprofit credit counseling agencies, work 

with creditors to develop repayment 

plans for consumers. These plans 

typically permit a consumer to repay the 

full credit balance owed under 

renegotiated terms, such as substantially 

reduced interest rates and fees. For 

consumers who are unable to repay the 

full balance owed, ‘‘debt settlement’’ 

entities offer to negotiate with a 

consumer’s creditors to enable the 

consumer to make a lump-sum payment 

of less than the entire balance owed to 

the creditor, thereby settling the debt 

obligation. Statistics on the size of these 

industries, as well as the size of other 

debt relief services, are not readily 

available.35 The CFPB will need to 

consider carefully how to define any 

debt relief provider market or markets 

included in an initial rule. 

The CFPB seeks public comment on 

the following: 

• What consumer financial product or 

service markets should be included in 

the initial rule? 

• How should the financial product 

or service markets included in the 

initial rule be defined? In addition to 

considerations relating to how to define 

the relevant product markets, should all 

markets be national in scope, or should 

the CFPB consider regional or other 

geographic markets in certain instances? 

If regional or other geographic markets 

should be considered, describe with 

specificity how they could be defined. 

• What specific criteria should be 

measured, and threshold levels set, to 

define a larger participant in the 

markets identified above, and in any 

other markets that should be included 

in an initial rule? What data should be 

used to assess whether the thresholds 

have been met?

products listed above. This proposed 


srobinson on DSK4SPTVN1PROD with PROPOSALS
Federal Register / Vol. 76, No. 125 / Wednesday, June 29, 2011 / Proposed Rules 38063 

AD results from mandatory continuing 

airworthiness information (MCAI) 

originated by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

Cracked nuts * * * were found on 

aircraft’s production line during routine post 

assembly inspection. Investigation revealed 

that the cracks resulted from hydrogen 

embrittlement combined with high hardness. 

Non-conformity with certified mechanical 

properties of this fastener can potentially 

lead to an unsafe condition. 

The unsafe condition is cracked nuts in 

multiple locations (including aileron 

fittings, rudder tab assembly and 

mounting structure for power drive 

units) could result in failure of affected 

locations and consequent reduced 

controllability or reduced structural 

capability of the airplane. The proposed 

AD would require actions that are 

intended to address the unsafe 

condition described in the MCAI.

Discussion 

The Civil Aviation Authority of Israel 

(CAAI), which is the aviation authority 

for Israel, has issued Israeli 

Airworthiness Directive 57–10–06–18, 

dated July 27, 2010 (referred to after this 

as ‘‘the MCAI’’), to correct an unsafe 

condition for the specified products. 

The MCAI states: 

Cracked nuts (P/N [part number] MS– 

21042L3) were found on aircraft’s production 

line during routine post assembly inspection. 

Investigation revealed that the cracks 

resulted from hydrogen embrittlement 

combined with high hardness. Nonconformity with certified mechanical 

properties of this fastener can potentially 

lead to an unsafe condition. 

The unsafe condition is cracked nuts in 

multiple locations (including aileron 

fittings, rudder tab assembly and 

mounting structure for power drive 

units) could result in failure of affected 

locations and consequent reduced 

controllability or reduced structural 

capability of the airplane. The required 

actions include replacing nuts having 

P/N MS–21042L3, and in certain 

locations, a one time radiographic 

inspection for cracked nuts and 

replacing any cracked nuts. You may 

obtain further information by examining 

the MCAI in the AD docket. 

Relevant Service Information 

Gulfstream Aerospace LP has issued 

Service Bulletin 200–51–366, dated 

March 30, 2010, including Appendix A: 

Israel Aircraft Industries Document 

IS951400E, Radiographic Inspection of 

Self-Locking Nut P/N MS21042L3, 

Revision A, dated January 25, 2010. The 

actions described in this service 

information are intended to correct the 

unsafe condition identified in the 

MCAI. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with the State of 

Design Authority, we have been notified 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all pertinent 

information and determined an unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Differences Between This AD and the 

MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 

general, agree with their substance. But 

we might have found it necessary to use 

different words from those in the MCAI 

to ensure the AD is clear for U.S. 

operators and is enforceable. In making 

these changes, we do not intend to differ 

substantively from the information 

provided in the MCAI and related 

service information. 

We might also have proposed 

different actions in this AD from those 

in the MCAI in order to follow FAA 

policies. Any such differences are 

highlighted in a NOTE within the 

proposed AD. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 2 products of U.S. registry. 

We also estimate that it would take 

about 227 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. Required 

parts would cost about $0 per product. 

Where the service information lists 

required parts costs that are covered 


srobinson on DSK4SPTVN1PROD with PROPOSALS
38064 Federal Register / Vol. 76, No. 125 / Wednesday, June 29, 2011 / Proposed Rules 

under warranty, we have assumed that 

there will be no charge for these costs. 

As we do not control warranty coverage 

for affected parties, some parties may 

incur costs higher than estimated here. 

Based on these figures, we estimate the 

cost of the proposed AD on U.S. 

operators to be $38,590, or $19,295 per 

product. 

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 above, I 

certify this proposed regulation: 

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); 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the 

AD docket.

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above that would 

supersede an existing AD. This 

proposed AD results from mandatory 

continuing airworthiness information 

(MCAI) originated by an aviation 

authority of another country to identify 

and correct an unsafe condition on an 

aviation product. The MCAI describes 

the unsafe condition as: 

Seven cases of on-ground hydraulic 

accumulator screw cap/end cap failure have 

been experienced on CL–600–2B19 

aeroplanes, resulting in the loss of the 

associated hydraulic system and high-energy 

impact damage to adjacent systems and 

structure. * * * 

* * * * * 

A detailed analysis of the calculated line 

of trajectory of a failed screw cap/end cap for 

each of the accumulators has been 

conducted, resulting in the identification of 

several areas where systems and/or structural 

components could potentially be damaged. 

Although all of the failures to date have 

occurred on the ground, an in-flight failure 

affecting such components could potentially 

have an adverse effect on the controllability 

of the aeroplane. 

* * * * * 

The proposed AD would require actions 

that are intended to address the unsafe 

condition described in the MCAI.

Discussion 

On October 7, 2010, we issued AD 

2010–22–02, Amendment 39–16481 (75 

FR 64636, October 20, 2010). That AD 

required actions intended to address an 

unsafe condition on Bombardier, Inc. 

Model CL–600–2B19 (Regional Jet 

Series 100 & 440) airplanes. 

Since we issued AD 2010–22–02, we 

have determined that further 

rulemaking is necessary. While AD 

2010–22–02 did not require the removal 

of the hydraulic system No. 3 

accumulator, or replacement of the 

hydraulic system No. 1, inboard brake, 

and outboard brake accumulators, as 

specified in Part IV and Part VII of the 

Canadian Airworthiness Directive CF– 

2010–24, dated August 3, 2010, this 

NPRM proposes to require those actions. 

Also, for airplanes on which 

Bombardier Service Bulletin 601R–29– 

035, dated May 11, 2010, is done and 

reducer having part number 

MS21916D8–6 installed, this NPRM 

proposes to require replacing the 

reducer with a new reducer. We have 

coordinated with Transport Canada 

Civil Aviation (TCCA) on this issue. 

Relevant Service Information 

Bombardier has issued Service 

Bulletin 601R–29–035, Revision A; and 

Service Bulletin 601R–32–107, Revision 

B; both dated December 8, 2010. The 

actions described in this service 

information as outlined in the 

‘‘Discussion’’ section above, are 

intended to correct the unsafe condition 

identified in the MCAI. 

Change to Existing AD 

This proposed AD would retain all 

requirements of AD 2010–22–02. Since 

AD 2010–22–02 was issued, the AD 

format has been revised, and certain 

paragraphs have been rearranged. As a 

result, the corresponding paragraph 

identifiers have changed in this 

proposed AD, as listed in the following
