prepared a Statement of Energy Effects. 

L. Executive Order 12630 

Pursuant to Executive Order 12630, 

‘‘Governmental Actions and Interference 

with Constitutionally Protected Property 

Rights,’’ 53 FR 8859 (March 15, 1988), 

DOE has determined that this rule 

would not result in any takings that 

might require compensation under the 

Fifth Amendment to the U.S. 

Constitution. 

M. Section 32 of the Federal Energy 

Administration Act of 1974 

Under section 301 of the Department 

of Energy Organization Act (Pub. L. 95– 

91), the Department of Energy must 

comply with section 32 of the Federal 

Energy Administration Act of 1974 

(Pub. L. 93–275), as amended by the 

Federal Energy Administration 

Authorization Act of 1977 (Pub. L. 95– 

70). (15 U.S.C. 788) Section 32 provides 

that where a proposed rule authorizes or 

requires use of commercial standards, 

the notice of proposed rulemaking must 

inform the public of the use and 

background of such standards. In 

addition, section 32(c) requires DOE to 

consult with the Department of Justice 

and the Federal Trade Commission 

concerning the impact of the 

commercial or industry standards on 

competition. This interim final rule 

does not authorize or require the use of 

any commercial standards. Therefore, 

no consultation with either DOJ or FTC 

is required. 

N. Congressional Notification 

As required by 5 U.S.C. 801, DOE will 

report to Congress on the promulgation 

of today’s rule before its effective date. 

The report will state that it has been 

determined that the rule is not a ‘‘major 

rule’’ as defined by 5 U.S.C. 804(2). 

V. Approval of the Office of the 

Secretary 

The Secretary of Energy has approved 

publication of this interim final rule.

Authority: 42 U.S.C. 6861 et seq.; 42 U.S.C. 

7101 et seq. 

■ 2. Section 440.2 is amended by adding 

a new paragraph (e) to read as follows: 

§ 440.2 Administration of grants. 

* * * * * 

(e)(1) States, Tribes and their 

subawardees, including, but not limited 

to subrecipients, subgrantees, 

contractors and subcontractors that 

participate in the program established 

under this Part are required to treat all 

requests for information concerning 

applicants and recipients of WAP funds 

in a manner consistent with the Federal 

government’s treatment of information 

requested under the Freedom of 

Information Act (FOIA), 5 U.S.C. 552, 

including the privacy protections 

contained in Exemption (b)(6) of the 

FOIA, 5 U.S.C. 552(b)(6). Under 5 U.S.C. 

552(b)(6), information relating to an 

individual’s eligibility application or 

the individual’s participation in the 

program, such as name, address, or 

income information, are generally 

exempt from disclosure. 

(2) A balancing test must be used in 

applying Exemption (b)(6) in order to 

determine: 

(i) Whether a significant privacy 

interest would be invaded; 

(ii) Whether the release of the 

information would further the public 

interest by shedding light on the 

operations or activities of the 

Government; and 

(iii) Whether in balancing the privacy 

interests against the public interest, 

disclosure would constitute a clearly 

unwarranted invasion of privacy. 

(3) A request for personal information 

including but not limited to the names, 

addresses, or income information of 

WAP applicants or recipients would 

require the State or other service 

provider to balance a clearly defined 

public interest in obtaining this 

information against the individuals’ 

legitimate expectation of privacy. 

(4) Given a legitimate, articulated 

public interest in the disclosure, States 

and other service providers may release 

information regarding recipients in the 

aggregate that does not identify specific 

individuals. However, a State or service 

provider must apply an FOIA 

Exemption (b)(6) balancing test to any 

request for information that can not be 

satisfied by such less-intrusive methods.

ACTION: Final rule. 

SUMMARY: We are superseding an 

existing airworthiness directive (AD) for 

the products listed above. This 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: 

There have been several cases of wing 

leading edge anti-ice piccolo duct failure 

reported on CL–600–2B19 (CRJ) aircraft. 

Upon investigation, it was determined that 

ducts manufactured since May 2000 are 

susceptible to cracking due to the process 

used to drill holes in the ducts. This cracking 

may cause air leakage, with a possible 

adverse effect on the anti-ice air distribution 

pattern and anti-ice capability, without 

annunciation to the flight crew [and 

consequent reduced controllability of the 

airplane]. 

* * * * * 

It has subsequently been determined that 

faulty ducts may also have been installed in 

a number of leading edge assemblies built as 

spares and whose current locations are not 

specifically known. * * * 

* * * * * 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective 

April 15, 2010. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of April 15, 2010.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM was published in the Federal 

Register on July 24, 2009 (74 FR 36628), 

and proposed to supersede AD 2008– 

23–16, Amendment 39–15737 (73 FR 

67363, November 14, 2008). That NPRM 

proposed to correct an unsafe condition 

for the specified products. 

The preamble to AD 2008–23–16 

explains that we consider those 

requirements ‘‘interim action’’ and were 

considering further rulemaking. We now 

have determined that further 

rulemaking is indeed necessary to 

require the previously optional 

terminating action, and this AD follows 

from that determination. Transport 

Canada Civil Aviation (TCCA), which is 

the aviation authority for Canada, 

previously issued Canadian 

Airworthiness Directive CF–2008–30, 

dated October 7, 2008 (referred to after 

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

condition for the specified products. 

The unsafe condition is cracked 

piccolo ducts, which could result in air 

leakage, a possible adverse effect on the 

anti-ice distribution pattern and anti-ice 

capability without annunciation to the 

flight crew, and consequent reduced 

controllability of the airplane. Required 

actions include revising the airplane 

flight manual, inspecting to determine if 

certain anti-ice piccolo ducts are 

installed, and replacing or repairing the 

piccolo duct if necessary. You may 

obtain further information by examining 

the MCAI in the AD docket. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM or 

on the determination of the cost to the 

public. 

Explanation of Changes Made to the AD 

We have revised this AD to identify 

the legal name of the manufacturer as 

published in the most recent type 

certificate data sheet for the affected 

airplane models. 

We have revised paragraph (j)(5) of 

this AD to remove reference to Master 

Minimum Equipment List (MMEL) 

Entry 30–12–03. However, we have 

approved operation of the airplane 

according to MMEL Entry 30–12–03 as 

a method for complying with the 

requirements of paragraph (j)(5) of this 

AD. Operators may contact the Manager, 

New York ACO, ANE–170, for 

information regarding the use of MMEL 

Entry 30–12–03 for compliance with the 

requirements of paragraph (j)(5) of this 

AD. We have included a new Note 1 in 

this AD to specify that guidance on 

operating the airplane under certain 

conditions according to the MMEL can 

be found in MMEL Entry 30–12–03, and 

have renumbered subsequent notes 

accordingly. 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting the AD 

with the changes described previously. 

We determined that these changes will 

not increase the economic burden on 

any operator or increase the scope of the 

AD. 

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 required different 

actions in this AD from those in the 

MCAI in order to follow our FAA 

policies. Any such differences are 

highlighted in a NOTE within the AD. 

Explanation of Change to Costs of 

Compliance 

Since issuance of the NPRM, we have 

increased the labor rate used in the 

Costs of Compliance from $80 per workhour to $85 per work-hour. The Costs of 

Compliance information, below, reflects 

this increase in the specified hourly 

labor rate. 

Costs of Compliance 

We estimate that this AD will affect 

about 711 products of U.S. registry. 

The actions that are required by AD 

2008–23–16 and retained in this AD 

take about 3 work-hours per product, at 

an average labor rate of $85 per work 

hour. Required parts cost about $0 per 

product. Based on these figures, the 

estimated cost of the currently required 

actions is $181,305, or $255 per 

product. 

We estimate that it will take about 12 

work-hours per product to comply with 

the new basic requirements of this AD. 

The average labor rate is $85 per workhour. Required parts will cost about $0 

per product. Where the service 

information lists required parts costs 

that are covered 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 

this AD to the U.S. operators to be 

$725,220, or $1,020 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 AD will not 

have federalism implications under 

Executive Order 13132. This AD will 

not have a substantial direct effect on 


jlentini on DSKJ8SOYB1PROD with RULES
11424 Federal Register / Vol. 75, No. 47 / Thursday, March 11, 2010 / Rules and Regulations 

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 AD: 

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 AD and placed it in the AD docket. 

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 the NPRM, the regulatory 

evaluation, any comments received, and 

other information. The street address for 

the Docket Operations office (telephone 

(800) 647–5527) is in the ADDRESSES

Adoption of the Amendment 

■ Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 14 CFR part 39 as 

follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

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

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by 

removing Amendment 39–15737 (73 FR 

67363, November 14, 2008) and adding 

the following new AD: 

2009–22–05 Bombardier, Inc.: Amendment 

39–16056. Docket No. FAA–2009–0656; 

Directorate Identifier 2009–NM–038–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective April 15, 2010. 

Affected ADs 

(b) This AD supersedes AD 2008–23–16, 

Amendment 39–15737. 

Applicability 

(c) This AD applies to Bombardier, Inc. 

Model CL–600–2B19 (Regional Jet Series 100 

& 440) airplanes, certificated in any category; 

serial numbers (S/Ns) 7003 through 7067 

inclusive, 7069 through 7990 inclusive, 8000 

through 8076 inclusive, 8082, 8086, 8090 

through 8092 inclusive, 8096, and 8097. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 30: Ice and rain protection. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

‘‘There have been several cases of wing 

leading edge anti-ice piccolo duct failure 

reported on CL–600–2B19 (CRJ) aircraft. 

Upon investigation, it was determined that 

ducts manufactured since May 2000 are 

susceptible to cracking due to the process 

used to drill holes in the ducts. This cracking 

may cause air leakage, with a possible 

adverse effect on the anti-ice air distribution 

pattern and anti-ice capability, without 

annunciation to the flight crew [and 

consequent reduced controllability of the 

airplane]. 

The faulty ducts were installed on aircraft 

SN 7417 through 7990 and 8000 through 

8055 in production, and as replacement parts 

on in service aircraft SN 7014, 7017, 7037, 

7046, 7059, 7076, 7105, 7127, 7151, 7157, 

7163, 7179, 7203, 7228, 7271, 7347, 7359, 

7362, 7378 and 7381. Service Bulletin (SB) 

601R–30–029, Revision B and AD CF–2005– 

26R1 previously covered the above aircraft 

serial numbers. 

It has subsequently been determined that 

faulty ducts may also have been installed in 

a number of leading edge assemblies built as 

spares and whose current locations are not 

specifically known. As they may have been 

installed on any of the aircraft serial numbers 

in the Applicability section of this directive, 

checking of records and/or inspection * * * 

is now required for all applicable aircraft. 

‘‘This directive, which supersedes and 

cancels AD CF–2005–26R1 [which 

corresponds to FAA AD 2005–17–12, 

amendment 39–14223], mandates the 

amendment of the Airplane Flight Manual 

(AFM) procedures, in addition to checking 

the part numbers and serial numbers of 

installed and spare wing anti-ice piccolo 

ducts, as required, and inspecting, replacing 

or repairing them as necessary. Terminating 

action is also introduced.’’ 

Required actions include revising the 

airplane flight manual, inspecting to 

determine if certain anti-ice piccolo ducts are 

installed, and replacing or repairing the 

piccolo duct if necessary. 

Restatement of Requirements of AD 2005– 

17–12 

Identification of Affected Piccolo Tubes 

(f) Unless already done, for airplanes 

having S/Ns 7013, 7017, 7037, 7046, 7059, 

7076, 7105, 7127, 7151, 7157, 7163, 7174, 

7179, 7203, 7204, 7228, 7271, 7347, 7362, 

7378, 7417 through 7990 inclusive, 8000 

through 8076 inclusive, 8082, 8086, 8090 

through 8092 inclusive, 8096 and 8097: 

Before the airplane accumulates 3,000 total 

flight hours, or within 14 days after 

September 7, 2005 (the effective date of AD 

2005–17–12, which was superseded by AD 

2008–23–16), whichever occurs later, 

determine whether any affected piccolo tube 

is installed on the airplane. Affected piccolo 

tubes are identified in paragraph 1.A. of 

Bombardier Service Bulletin 601R–30–029, 

Revision A, dated July 7, 2005. Doing the 

action required by paragraph (p), (q), (r), (w), 

or (y) of this AD terminates the requirements 

of this paragraph. 

Revision to Airplane Flight Manual (AFM) 

(g) Unless already done, for airplanes with 

an affected or unidentifiable piccolo tube 

found during the action required by 

paragraph (f) of this AD: Before the airplane 

accumulates 3,000 total flight hours, or 

within 14 days after September 7, 2005, 

whichever occurs later, revise the Operating 

Limitations and Abnormal Procedures 

sections of the Canadair Regional Jet AFM, 

CSP A–012, to include the information in 

Canadair Temporary Revision (TR) RJ/155, 

dated July 5, 2005, as specified in the TR. 

This may be done by inserting a copy of the 

TR into the AFM. This TR introduces new 

procedures for operation in icing conditions. 

Operate the airplane according to the 

limitations and procedures in the TR except 

as required by paragraph (n) of this AD. 

When this TR has been included in general 

revisions of the AFM, the general revisions 

may be inserted in the AFM, provided the 

relevant information in the general revision 

is identical to that in the TR. After the AFM 

revision required by paragraph (n) of this AD 

has been done, remove the AFM limitation 

specified in this paragraph. 

Optional Inspections 

(h) Unless already done, for airplanes with 

an affected or unidentifiable piccolo tube 

found during the action required by 

paragraph (f) of this AD: The operating 

limitations and abnormal procedures 

specified in Canadair TR RJ/155, dated July 

5, 2005, as required by paragraph (g) of this 

AD, may be removed from the AFM, 

provided all requirements of this paragraph 

have been satisfied. 

(1) A fluorescent dye penetrant inspection 

for cracks of the piccolo tubes is done and 

repeated thereafter within 2,000-flight-hour 

intervals in accordance with the 

Accomplishment Instructions of Bombardier 

Service Bulletin 601R–30–029, Revision A, 

dated July 7, 2005. An inspection done before 

September 7, 2005, in accordance with 

Bombardier Service Bulletin 601R–30–029, 

dated June 17, 2005, is acceptable for 

compliance with the requirements of 

paragraph (h)(1) of this AD. Doing the 

inspection required by paragraph (u) of this 

AD terminates the actions required by this 

paragraph. 

(2) All applicable corrective actions are 

done as specified in paragraph (j) of this AD. 

AFM Limitations Required for Exceeding 

Inspection Interval 

(i) Unless already done, for airplanes 

having S/Ns 7013, 7017, 7037, 7046, 7059,

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This 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: 

Cracks have been found on pylon side 

panels (upper section) at rib 8 on Airbus 

A300, A310 and A300–600 aircraft equipped 

with General Electric engines. Investigation 

of these findings indicates that this problem 

is likely to affect aircraft of this type design 

with other engine installations. This 

condition, if not corrected, can lead to 

reduced strength [structural integrity] of the 

pylon primary structure. 

* * * * * 

The unsafe condition is reduced 

structural integrity of the pylon primary 

structure, which could cause 

detachment of the engine from the 

fuselage. We are issuing this AD to 

require actions to correct the unsafe 

condition on these products. 

DATES: This AD becomes effective April 

15, 2010. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of April 15, 2010.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM was published in the Federal 

Register on September 21, 2009 (74 FR 

48024). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

Cracks have been found on pylon side 

panels (upper section) at rib 8 on Airbus 

A300, A310 and A300–600 aircraft equipped 

with General Electric engines. Investigation 

of these findings indicates that this problem 

is likely to affect aircraft of this type design 

with other engine installations. This 

condition, if not corrected, can lead to 

reduced strength [structural integrity] of the 

pylon primary structure. 

In order to detect any crack propagation at 

an early stage, thus avoiding an extensive 

repair, Airbus issued Service Bulletins (SB) 

A300–54–0075, A310–54–2018 and A300– 

54–6015. * * * 

This AD requires the implementation of 

this * * * inspection programme. 

The unsafe condition is reduced 

structural integrity of the pylon primary 

structure, which could cause 

detachment of the engine from the 

fuselage. Required actions include 

repetitive detailed visual inspections, or 

repetitive eddy current and detailed 

visual inspections, to detect cracks, 

depending on the airplane 

configuration, and corrective actions if 

necessary. The corrective actions 

include repairing the cracking, and 

contacting Airbus for repair instructions 

and doing the repair, as applicable. You 

may obtain further information by 

examining the MCAI in the AD docket. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

considered the comments received. 

Request To Clarify Reporting 

Requirement 

American Airlines requests that we 

remove the requirement for reporting 

findings to Airbus. The commenter 

states that Appendix 1, 2, and 3 in 

Airbus Service Bulletin A300–54–6015 

require findings to be reported; 

however, the proposed rule specifically 

excludes Appendix 1, 2, and 3 in Table 

2 of this AD. American Airlines states 

the difference is not addressed in the 

proposed rule. The commenter also 

states that reporting findings within a 

specified time period has no effect on 

improving safety and should not be 

mandated by the proposed rule. 

We agree that reporting inspection 

findings to Airbus is not necessary in 

this AD for the reasons stated by the 

commenter. Since the MCAI requires 

reporting inspection findings to Airbus 

and it is not our intent to require those 

reports, we have added Note 2 in this 

AD to clarify that this AD does not 

include a reporting requirement. 

Request To Refer to Paragraph 3.B. in 

Airbus Mandatory Service Bulletin 

A300–54–6015, Revision 02, Dated June 

26, 2008, for Inspection Task 

The commenter, R. L. Vernon, 

requests that paragraph (f)(1) of the 

NPRM refer to paragraph 3.B. of Airbus 

Mandatory Service Bulletin A300–54– 

6015, Revision 02, dated June 26, 2008, 

rather than paragraph 3.E., for the 

inspection task. The commenter states
