Airworthiness Directives; Pratt & 

Whitney PW4000 Series Turbofan 

Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

Pratt & Whitney PW4000 series turbofan 

engines. This AD requires initial and 

repetitive borescope inspections (BSI) or 

fluorescent penetrant inspections (FPI) 

for cracks in the anti-vortex tube (AVT) 

shelf slots on the 10th stage disk of the 

high-pressure compressor (HPC) drum 

rotor disk assembly. This AD results 

from 47 reports received since 2007 of 

HPC 10th stage disks found cracked in 

the AVT shelf slots during shop visit 

inspections. We are issuing this AD to 

prevent failure of the HPC 10th stage 

disk, uncontained engine failure, and 

damage to the airplane. 

DATES: This AD becomes effective 

January 21, 2011. The Director of the 

Federal Register approved the 

incorporation by reference of certain 

publications listed in the regulations as 

of January 21, 2011. 

ADDRESSES: You can get the service 

information identified in this AD from 

Pratt & Whitney, 400 Main St., East 

Hartford, CT 06108; telephone (860)

SUPPLEMENTARY INFORMATION: The FAA 

proposed to amend 14 CFR part 39 with 

a proposed AD. The proposed AD 

applies to certain Pratt & Whitney 

PW4000 series turbofan engines. We 

published the proposed AD in the 

Federal Register on July 14, 2010 (75 FR 

40757). That action proposed to require 

initial and repetitive BSI or FPI for 

cracks in the AVT shelf slots on the 10th 

stage disk of the HPC drum rotor disk 

assembly. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Operations office between 9 a.m. 

and 5 p.m., Monday through Friday, 

except Federal holidays. The AD docket 

contains this AD, the regulatory 

evaluation, any comments received, and 

other information. The street address for 

the Docket Operations office (telephone 

(800) 647–5527) is provided in the 

ADDRESSES section. Comments will be 

available in the AD docket shortly after 

receipt. 

Comments 

We provided the public the 

opportunity to participate in the 

development of this AD. We have 

considered the comments received. 

Request for Airplane Model Changes in 

the Applicability 

One commenter, The Boeing 

Company, requests that we change the 

list of airplane models in the 

applicability paragraph. The commenter 

requests that we add the 747–400 and 

–400F airplane models, and remove the 

747–200 airplane model. These changes 

will make the list accurate. 

We agree. We changed the AD 

applicability to reflect these changes. 

Request To Include Engine Removal 

Disassembly Labor Costs 

One commenter, Japan Airlines, 

requests that we change the costs of 

compliance estimate to include engine 

removal and disassembly labor costs. 

The commenter states that their 

domestic routes can go 7,000 cycles-inservice or more between engine 

overhauls. Since the inspection 

compliance interval in the proposed AD 

is within every 7,200 cycles-in-service, 

some of their engines could be removed 

and disassembled before they would 

normally be scheduled. 

We do not agree. The inspection 

compliance interval of within every 

7,200 cycles-in-service captures when 

most of the fleet will remove the lowpressure turbine shaft, or overhaul the 

HPC. Most operators will incur no 

additional costs. We did not change the 

AD. 

Request To Add Service Bulletins as 

Terminating Action 

Two commenters, Martinair Holland 

and Delta Airlines, Inc., request that we 

add Pratt & Whitney Service Bulletin 

(SB) No. PW4ENG 72–801 to the AD as 

terminating action for the repeat 

inspection. The commenters state that 

Pratt & Whitney issued that SB, as well 

as SB No. PW4G–100–72–225, to 

introduce a redesigned HPC 9th stage 

stator that will correct the cracking 

problem. 

We agree. We modified the AD to 

include optional terminating action for 

the repetitive inspections. 

Reference the Latest Service Bulletin 

Since we issued the proposed AD, 

Pratt & Whitney has issued Revision 1 

of Pratt & Whitney SB No. PW4ENG 72– 

799. We updated the AD to reference 

Revision 1 of this SB.

78882 Federal Register / Vol. 75, No. 242 / Friday, December 17, 2010 / Rules and Regulations 

Conclusion 

We have carefully reviewed the 

available data, including the comments 

received, and determined that air safety 

and the public interest require adopting 

the AD with the changes described 

previously. We have determined that 

these changes will neither increase the 

economic burden on any operator nor 

increase the scope of the AD. 

Interim Actions 

These actions are interim actions and 

we may take further rulemaking actions 

in the future. 

Costs of Compliance 

We estimate that this AD will affect 

869 engines installed on airplanes of 

U.S. registry. We also estimate that it 

will take about one work-hour per 

engine to perform an inspection, and 

that the average labor rate is $85 per 

work-hour. Required parts will cost 

about $303,010 per HPC drum rotor disk 

assembly. About 61 HPC drum rotor 

disk assemblies will need replacement 

due to cracks. Based on these figures, 

we estimate the cost of the AD on U.S. 

operators to be $18,557,475. 

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 have determined that 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); 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 summary of the costs 

to comply with this AD and placed it in 

the AD Docket. You may get a copy of 

this summary at the address listed 

under ADDRESSES.

Implementation of Additional Changes 

From the Annual Review of the Entity 

List 

AGENCY: Bureau of Industry and 

Security, Commerce. 

ACTION: Final rule. 

SUMMARY: This rule amends the Export 

Administration Regulations (EAR) to 

implement additional changes to the 

Entity List (Supplement No. 4 to Part 

744) on the basis of the annual review 

of the Entity List conducted by the EndUser Review Committee (ERC). The 

changes from the annual review will be 

implemented in three rules. The first 

rule published on May 28, 2010 (75 FR 

29884) implemented the results of the 

annual review for listed entities located 

in Canada, Egypt, Germany, Hong Kong, 

Israel, Kuwait, Lebanon, Malaysia, 

South Korea, Singapore, and the United 

Kingdom. 

The second rule, published today, 

implements the results of the annual 

review for entities located in China and 

Russia. This rule removes five entities 

from the Entity List under Russia and 

makes twenty-one modifications to the 

Entity List (consisting of modifications 

to eighteen Chinese entries and three 

Russian entries currently on the Entity 

List) by adding additional addresses, 

aliases and/or clarifying the names for 

these twenty-one entities. 

The third rule, which will likely be 

published in early 2011, will implement 

the remaining results of the annual 

review. 

The Entity List provides notice to the 

public that certain exports, reexports, 

and transfers (in-country) to entities 

identified on the Entity List require a 

license from the Bureau of Industry and 

Security and that availability of license 

exceptions in such transactions is 

limited. 

DATES: Effective Date: This rule is 

effective December 17, 2010. Although 

there is no formal comment period, 

public comments on this regulation are 

welcome on a continuing basis. 

ADDRESSES: You may submit comments, 

identified by RIN 0694–AF01, by any of 

the following methods: 

E-mail: publiccomments@bis.doc.gov.
