AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above. This proposed 

AD results from mandatory continuing 

airworthiness information (MCAI) 

issued 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: 

During manufacture of a number of HP 

Compressor Stage 1 and 2 discs with axial 

dovetail slots, anomalies at the disc post 

corners have been found. Fatigue crack 

initiation and subsequent crack propagation 

at the disc post may result in release of two 

blades and the disc post. This may 

potentially be beyond the containment 

capabilities of the engine casings. Thus, these 

anomalies present at the disc posts constitute 

a potentially unsafe condition. 

We are proposing this AD to detect 

cracks in the high-pressure compressor 

(HPC) Stage 1 and 2 disc posts, which 

could result in failure of the disc post 

and HPC blades, release of uncontained 

engine debris, and damage to the 

airplane. 

DATES: We must receive comments on 

this proposed AD by July 30, 2010.

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directive 2009–0073R1, 

dated April 8, 2009, (referred to after 

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

condition for the specified products. 

The MCAI states: 

During manufacture of a number of HP 

Compressor Stage 1 and 2 discs with axial 

dovetail slots, anomalies at the disc post 

corners have been found. Fatigue crack 

initiation and subsequent crack propagation 

at the disc post may result in release of two 

blades and the disc post. This may 

potentially be beyond the containment 

capabilities of the engine casings. Thus, these 

anomalies present at the disc posts constitute 

a potentially unsafe condition. 

For the reasons described above, this AD 

requires repetitive inspections of the axial 

dovetail slots and follow-on corrective 

action, depending on findings. 

You may obtain further information 

by examining the MCAI in the AD 

docket. 

Relevant Service Information 

Rolls-Royce plc has issued Alert 

Service Bulletin RB.211–72–AF964, 

Revision 1, dated June 6, 2008. 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 the United 

Kingdom, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with the United 

Kingdom, they have notified us of the 

unsafe condition described in the MCAI 

and service information referenced 

above. We are proposing this AD 

because we evaluated all information 

provided by EASA, and determined the 

unsafe condition exists and is likely to 

exist or develop on other products of the 

same type design. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 371 products of U.S. 

registry. We also estimate that it would 

take about 20 work-hours per product to 

comply with this proposed AD. The 

average labor rate is $85 per work-hour. 

No parts would be required per product. 

Based on these figures, we estimate the 

cost of the proposed AD on U.S. 

operators to be $630,700. 

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 


sroberts on DSKD5P82C1PROD with PROPOSALS
Federal Register / Vol. 75, No. 114 / Tuesday, June 15, 2010 / Proposed Rules 33739 

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.

FK24009, FK26167, FK32580, FW11590, or FW61622. 

Reason 

(d) This AD results from reports that: 

‘‘During manufacture of a number of HP 

Compressor Stage 1 and 2 discs with axial 

dovetail slots, anomalies at the disc post 

corners have been found. Fatigue crack 

initiation and subsequent crack propagation 

at the disc post may result in release of two 

blades and the disc post. This may 

potentially be beyond the containment 

capabilities of the engine casings. Thus, these 

anomalies present at the disc posts constitute 

a potentially unsafe condition.’’ 

We are issuing this AD to detect cracks in 

the high-pressure compressor (HPC) Stage 1 

and 2 disc posts, which could result in 

failure of the disc post and HPC blades, 

release of uncontained engine debris, and 

damage to the airplane. 

Actions and Compliance 

(e) Unless already done, do the following 

actions. 

(1) Perform a fluorescent penetrant 

inspection of the HP compressor stage 1 to 

4 rotor discs at the first shop visit after 

accumulating 1000 cycles since new on the 

stage 1 to 4 rotor disks or at the next shop 

visit after the effective date of this AD which 

ever occurs later. Use paragraph 3.E.(1) 

through 3.E.(10)(i) of the Accomplishment 

Instructions of Rolls-Royce Alert Service 

Bulletin (ASB) RB.211–72–AF964, Revision 

1, dated June 6, 2008 to do the inspections. 

(2) Thereafter at every engine shop visit, 

perform the inspection specified by 

paragraph (e)(1) of this AD. 

Definitions 

(f) 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 without subsequent engine 

maintenance does not constitute an engine 

shop visit. 

Other FAA AD Provisions 

(g) Alternative Methods of Compliance 

(AMOCs): The Manager, Engine Certification 

Office, FAA, has the authority to approve 

AMOCs for this AD, if requested using the 

procedures found in 14 CFR 39.19.

SUPPLEMENTARY INFORMATION: 

Paperwork Reduction Act 

The collection of information 

contained in this notice of proposed 

rulemaking has been approved by the 

Office of Management and Budget in 

accordance with the Paperwork 

Reduction Act of 1995 (44 U.S.C. 

3507(d)) and assigned control number 

1545–2177. Comments on the collection 

of information should be sent to the 

Office of Management and Budget, Attn: 

Desk Officer for the Department of the 

Treasury, Office of Information and 

Regulatory Affairs, Washington, DC 

20503, with copies to the Internal 

Revenue Service, Attn: IRS Reports 

Clearance Officer, 

SE:W:CAR:MP:T:T:SP, Washington, DC 

20224. Comments on the collection of 

information should be received by 

September 13, 2010. Comments are 

specifically requested concerning: 

Whether the proposed collection of 

information is necessary for the proper 

performance of the functions of the 

Internal Revenue Service, including 

whether the information will have 

practical utility; 

The accuracy of the estimated burden 

associated with the proposed collection 

of information; 

How the quality, utility, and clarity of 

the information to be collected may be 

enhanced; 

How the burden of complying with 

the proposed collections of information 

may be minimized, including through 

the application of automated collection 

techniques or other forms of information 

technology; and 

Estimates of capital or start-up costs 

of operation, maintenance, and 

purchase of service to provide 

information. 

The collection of information in this 

proposed regulation is in proposed 

§ 49.5000B–1(d)(2). This information is 

required to be maintained in order for 

providers of indoor tanning services to 

accurately calculate the tax on indoor 

tanning services when those services are 

offered with other goods and services. 

The likely recordkeepers are providers 

of indoor tanning services. 

Estimated total average annual 

recordkeeping burden: 10,000 hours. 

Estimated average annual burden 

hours per recordkeeper: 30 minutes. 

Estimated number of recordkeepers: 

20,000. 

An agency may not conduct or 

sponsor, and a person is not required to 

respond to, a collection of information 

unless the collection of information 

displays a valid control number 

assigned by the Office of Management 

and Budget. 

Books or records relating to a 

collection of information must be 

retained as long as their contents may 

become material in the administration 

of any internal revenue law. Generally, 

tax returns and tax return information 

are confidential, as required by 26 

U.S.C. 6103. 

Background 

This document contains proposed 

amendments to the Excise Tax 

Procedural Regulations (26 CFR part 40) 

and the Facilities and Services Excise 

Tax Regulations (26 CFR part 49) under 

section 5000B of the Internal Revenue 

Code (Code). Section 5000B of the Code 

was enacted by section 10907 of the 

Patient Protection and Affordable Care 

Act, Public Law 111–148 (124 Stat. 119 

(2010)) to impose an excise tax on 

indoor tanning services. The text of 

temporary regulations published in this 

issue of the Federal Register also serves 

as the text of these proposed 

regulations. The preamble to the 

temporary regulations explains the 

temporary regulations. 

Special Analyses 

It has been determined that this notice 

of proposed rulemaking is not a 

significant regulatory action as defined 

in Executive Order 12866. Therefore, a 

regulatory assessment is not required. It 

has been determined that section 553(b) 

of the Administrative Procedure Act (5 

U.S.C. chapter 5) does not apply to these 

regulations. It is hereby certified that 

these regulations will not have a 

significant economic impact on a 

substantial number of small entities. 

This certification is based on the fact 

that these regulations are designed to 

accommodate the recordkeeping 

methods currently used by small 

entities that provide indoor tanning 

services. The regulations merely 

implement the tax imposed by section 

5000B of the Code, and section 6001 of 

the Code already requires taxpayers to 

keep books and records sufficient to 

show whether or not they are liable for 

tax. The information necessary to 

prepare these records is readily 

available to providers, and this 

recordkeeping will take little additional 

time to complete. Accordingly, a 

Regulatory Flexibility Analysis under 

the Regulatory Flexibility Act (5 U.S.C. 

chapter 6) is not required. Pursuant to 

section 7805(f) of the Code, this 

regulation has been submitted to the 

Chief Counsel for Advocacy of the Small 

Business Administration for comment 

on its impact on small business. 

Comments and Requests for a Public 

Hearing 

Before these proposed regulations are 

adopted as final regulations, 

consideration will be given to any 

written comments (a signed original and 

eight (8) copies) or electronic comments
