13684 Federal Register / Vol. 75, No. 55 / Tuesday, March 23, 2010 / Proposed Rules 

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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

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 

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 adding 

the following new AD: 

Bombardier, Inc.: Docket No. FAA–2010– 

0273; Directorate Identifier 2009–NM– 

134–AD. 

Comments Due Date 

(a) We must receive comments by May 7, 

2010. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Bombardier, Inc. 

Model DHC–8–400, DHC–8–401, and DHC– 

8–402 series airplanes, certificated in any 

category; serial numbers 4001, 4003, 4004, 

4006, and 4008 through 4238 inclusive. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 32: Landing gear. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

Two in-service incidents have been 

reported on DHC–8 Series 400 aircraft in 

which the nose landing gear (NLG) trailing 

arm pivot pin retention bolt (part number 

NAS6204–13D) was damaged. One incident 

involved the left hand NLG tire which 

ruptured on take-off. Investigation 

determined that the retention bolt failure was 

due to repeated contact of the castellated nut 

with the towing device including both the 

towbar and the towbarless rigs. The loss of 

the retention bolt allowed the pivot pin to 

migrate from its normal position and resulted 

in contact with and rupture of the tire. The 

loss of the pivot pin could compromise 

retention of the trailing arm and could result 

in a loss of directional control due to loss of 

nose wheel steering. The loss of an NLG tire 

or the loss of directional control could 

adversely affect the aircraft during take off or 

landing. 

To prevent the potential failure of the pivot 

pin retention bolt, Bombardier Aerospace has 

developed a modification which includes a 

new retention bolt, a reverse orientation of 

the retention bolt and a rework of the weight 

on wheel (WOW) proximity sensor cover to 

provide clearance for the re-oriented 

retention bolt. 

Actions and Compliance 

(f) Unless already done, do the following 

actions. 

(1) Within 2,000 flight hours after the 

effective date of this AD: Modify the NLG 

trailing arm by incorporating Bombardier 

Modification Summary 4–113599, in 

accordance with the Accomplishment 

Instructions of Bombardier Service Bulletin 

84–32–65, Revision A, dated March 2, 2009. 

(2) Incorporating Bombardier Modification 

Summary 4–113599 in accordance with the 

Accomplishment Instructions of Bombardier 

Service Bulletin 84–32–65, dated December 

17, 2008, is also acceptable for compliance 

with the requirements of paragraph (f)(1) of 

this AD if done before the effective date of 

this AD. 

FAA AD Differences 

Note 1: This AD differs from the MCAI 

and/or service information as follows: No 

differences. 

Other FAA AD Provisions 

(g) The following provisions also apply to 

this AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, New York Aircraft 

Certification Office, ANE–170, FAA, has the 

authority to approve AMOCs for this AD, if 

requested using the procedures found in 14 

CFR 39.19. Send information to ATTN:

Safety, FAA, New York ACO, 1600 Stewart 

Avenue, Suite 410, Westbury, New York, 

11590; telephone 516–228–7300; fax 516– 

794–553. Before using any approved AMOC 

on any airplane to which the AMOC applies, 

notify your principal maintenance inspector 

(PMI) or principal avionics inspector (PAI), 

as appropriate, or lacking a principal 

inspector, your local Flight Standards District 

Office. The AMOC approval letter must 

specifically reference this AD. 

(2) Airworthy Product: For any requirement 

in this AD to obtain corrective actions from 

a manufacturer or other source, use these 

actions if they are FAA-approved. Corrective 

actions are considered FAA-approved if they 

are approved by the State of Design Authority 

(or their delegated agent). You are required 

to assure the product is airworthy before it 

is returned to service. 

(3) Reporting Requirements: For any 

reporting requirement in this AD, under the 

provisions of the Paperwork Reduction Act 

(44 U.S.C. 3501 et seq.), the Office of 

Management and Budget (OMB) has 

approved the information collection 

requirements and has assigned OMB Control 

Number 2120–0056.

ACTION: Supplemental notice of 

proposed rulemaking (NPRM); 

reopening of comment period. 

SUMMARY: We are revising an earlier 

NPRM for the products listed above that 

would supersede an existing AD. This 

action revises the earlier NPRM by 

expanding the scope. 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 earlier MCAI, Brazilian 

Airworthiness Directive 2007–08–01, 

effective September 27, 2007, describes 

the unsafe condition as: 

Fuel system reassessment, performed 

according to RBHA–E88/SFAR–88

new maintenance tasks in the Critical Design 

Configuration Control Limitations (CDCCL) 

and in the Fuel System Limitations (FSL), 

necessary to preclude ignition sources in the 

fuel system. * * * 

The new MCAI, Brazilian Airworthiness 

Directive 2009–08–03, effective August 

20, 2009, describes the unsafe condition 

as: 

An airplane fuel tank systems review 

required by Special Federal Aviation 

Regulation Number 88 (SFAR 88) and ‘‘RBHA 

Especial Nu ́mero 88’’ (RBHA E 88) has shown 

that additional maintenance and inspection 

instructions are necessary to maintain the 

design features required to preclude the 

existence or development of an ignition 

source within the fuel tanks of the airplane. 

* * * * * 

The proposed AD would require actions 

that are intended to address the unsafe 

condition described in the MCAI.

Discussion 

We proposed to amend 14 CFR part 

39 with an earlier NPRM for the 

specified products, which was 

published in the Federal Register on 

October 16, 2008 (73 FR 61375). That 

earlier NPRM proposed to supersede AD 

2008–13–15, Amendment 39–15578 (73 

FR 35908, June 25, 2008), to require 

actions intended to address the unsafe 

condition for the products listed above. 

Since that NPRM was issued, the 

Ageˆncia Nacional de Aviac ̧a ̃o Civil 

(ANAC), which is the aviation authority 

for Brazil, has issued Airworthiness 

Directive 2009–08–03, dated August 20, 

2009 (referred to after this as ‘‘the 

MCAI’’), to correct an unsafe condition 

for the specified products. The MCAI 

states: 

An airplane fuel tank systems review 

required by Special Federal Aviation 

Regulation Number 88 (SFAR 88) and ‘‘RBHA 

Especial Nu ́mero 88’’ (RBHA E 88) has shown 

that additional maintenance and inspection 

instructions are necessary to maintain the 

design features required to preclude the 

existence or development of an ignition 

source within the fuel tanks of the airplane. 

* * * * * 

The corrective action is revising the 

Airworthiness Limitations Section 

(ALS) of the Instructions for Continued 

Airworthiness (ICA) to incorporate new 

limitations for fuel tank systems. You 

may obtain further information by 

examining the MCAI in the AD docket. 

Additional Actions Since NPRM Was 

Issued 

Since we issued the earlier NPRM, 

which included a proposal to require 

incorporation of critical design 

configuration control limitations 

(CDCCLs), we have determined that it is 

necessary to clarify the proposed AD’s 

intended effect on spare and on-airplane 

fuel tank system components, regarding 

the use of maintenance manuals and 

instructions for continued 

airworthiness. 

Section 91.403(c) of the Federal 

Aviation Regulations (14 CFR 91.403(c)) 

specifies the following: 

No person may operate an aircraft for 

which a manufacturer’s maintenance manual 

or instructions for continued airworthiness 

has been issued that contains an 

airworthiness limitation section unless the 

mandatory procedures have been complied 

with. 

Some operators have questioned 

whether existing components affected 

by the new CDCCLs must be reworked. 

We did not intend for the AD to 

retroactively require rework of 

components that had been maintained 

using acceptable methods before the 

effective date of the AD. Owners and 

operators of the affected airplanes 

therefore are not required to rework 

affected components identified as 

airworthy or installed on the affected 

airplanes before the required revisions 

of the ALS of the ICA. But once the 

CDCCLs are incorporated into the ALS 

of the ICA, future maintenance actions 

on components must be done in 

accordance with those CDCCLs. 

Comments 

We have considered the following 

comment received on the earlier NPRM. 

Request To Revise Actions Specified in 

Table 2 of the NPRM 

Embraer requests that we revise the 

actions specified in Table 2 of the 

NPRM (functional checks of the fuel 

conditioning unit and the ventral fuel 

conditioning unit). Embraer states that a 

functional check of the fuel 

conditioning unit would not entirely 

address the unsafe condition and that a 

functional check of the safe-life features 

in connection with internal and external 


wwoods2 on DSK1DXX6B1PROD with PROPOSALS_PART 1
13686 Federal Register / Vol. 75, No. 55 / Tuesday, March 23, 2010 / Proposed Rules 

inspections is necessary. Embraer notes 

that Parker revised Component 

Maintenance Manual (CMM) 28–41–36 

on March 5, 2007, to include a 

functional check of the safe-life features 

for fuel conditioning unit part number 

(P/N) 367–934–001. Embraer 

recommends that a functional check of 

the safe-life features and inspections to 

ensure the safe-life features be included 

in Table 2 of the NPRM. Embraer also 

suggests that Parker Service Bulletin 

367–934–28–110, Revision A, dated 

December 19, 2006, be included as an 

optional method of compliance for 

doing the safe-life check. 

We agree to revise Table 2 of the 

supplemental NPRM to include new 

actions to check and inspect safe-life 

features to adequately address the 

identified unsafe condition. However, 

we have not included fuel conditioning 

unit P/N 367–934–001, as the part is not 

installed on Model EMB–135BJ 

airplanes. We have revised Table 2 of 

this AD to include fuel conditioning 

unit P/Ns 367–934–002, 367–934–004, 

and 367–934–006. However, we have 

not included Parker Service Bulletin 

367–934–28–110, Revision A, dated 

December 19, 2006, as an optional 

method of compliance because that 

service bulletin does not refer to a 

specific component maintenance 

manual. Instead, we have included the 

Parker CMMs for these part numbers in 

Table 2 of this AD, as specified in the 

following table. We have coordinated 

this action with ANAC.

We have also revised the ‘‘Grace 

Period’’ specified in Table 2 of the 

supplemental NPRM from ‘‘Within 90 

days after December 16, 2008’’ to 

‘‘Within 90 days after the effective date 

of this AD.’’ 

We have also revised paragraph (g)(1) 

of this AD to clarify that the new tasks 

are part of the ALS of the ICA and 

added a 30-day compliance time to 

revise the ALS of the ICA to incorporate 

the new tasks. 

Clarification of Service Information 

Paragraph (f)(1) of the original NPRM 

defines the term ‘‘MPG’’ as EMBRAER 

Legacy BJ–Maintenance Planning Guide 

(MPG) MPG–1483, Revision 5, dated 

March 22, 2007. However, instead of 

using the term ‘‘MPG’’ in this 

supplemental NPRM, we have used the 

full document citation throughout this 

supplemental NPRM, as appropriate. 

Therefore, we have removed paragraph 

(f)(1) of the NPRM from this 

supplemental NPRM and have revised 

the subsequent paragraph identifiers 

accordingly. 

Explanation of Change to Costs of 

Compliance 

Since issuance of the original NPRM, 

we have increased the labor rate used in 

the Costs of Compliance from $80 per 

work-hour to $85 per work-hour. The 

Costs of Compliance information, 

below, reflects this increase in the 

specified hourly labor rate. 

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. 

Certain changes described above 

expand the scope of the earlier NPRM. 

As a result, we have determined that it 

is necessary to reopen the comment 

period to provide additional 

opportunity for the public to comment 

on this proposed 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 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 43 products of U.S. registry. 

The actions that are required by AD 

2008–13–15 and retained in this 

proposed AD take about 1 work-hour 

per product, at an average labor rate of 

$85 per work hour. Based on these 

figures, the estimated cost of the 

currently required actions is $85 per 

product. 

We estimate that it would take about 

1 work-hour per product to comply with 

the new basic requirements of this 

proposed AD. The average labor rate is 

$85 per work-hour. Based on these 

figures, we estimate the cost of the 

proposed AD on U.S. operators to be 

$3,655, or $85 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 


wwoods2 on DSK1DXX6B1PROD with PROPOSALS_PART 1
Federal Register / Vol. 75, No. 55 / Tuesday, March 23, 2010 / Proposed Rules 13687 

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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

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 

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 39–15578 (73 FR 

35908, June 25, 2008) and adding the 

following new AD: 

Empresa Brasileira de Aeronautica S.A. 

(EMBRAER): Docket No. FAA–2008– 

1080; Directorate Identifier 2008–NM– 

118–AD. 

Comments Due Date 

(a) We must receive comments by April 19, 

2010. 

Affected ADs 

(b) This AD supersedes AD 2008–13–15, 

Amendment 39–15578. 

Applicability 

(c) This AD applies to all Empresa 

Brasileira de Aeronautica S.A. (EMBRAER) 

Model EMB–135BJ airplanes, certificated in 

any category. 

Note 1: This AD requires revisions to 

certain operator maintenance documents to 

include new inspections. Compliance with 

these inspections is required by 14 CFR 

91.403(c). For airplanes that have been 

previously modified, altered, or repaired in 

the areas addressed by these inspections, the 

operator may not be able to accomplish the 

inspections described in the revisions. In this 

situation, to comply with 14 CFR 91.403(c), 

the operator must request approval for an 

alternative method of compliance according 

to paragraph (h)(1) of this AD. The request 

should include a description of changes to 

the required inspections that will ensure the 

continued operational safety of the airplane. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 28: Fuel. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI), Brazilian 

Airworthiness Directive 2007–08–01, 

effective September 27, 2007, states: 

Fuel system reassessment, performed 

according to RBHA–E88/SFAR–88 

(Regulamento Brasileiro de Homologacao 

Aeronautica 88/Special Federal Aviation 

Regulation No. 88), requires the inclusion of 

new maintenance tasks in the Critical Design 

Configuration Control Limitations (CDCCL) 

and in the Fuel System Limitations (FSL), 

necessary to preclude ignition sources in the 

fuel system. * * * 

And the MCAI, Brazilian Airworthiness 

Directive 2009–08–03, effective August 20, 

2009, states: 

An airplane fuel tank systems review 

required by Special Federal Aviation 

Regulation Number 88 (SFAR 88) and ‘‘RBHA 

Especial Nu ́mero 88’’ (RBHA E 88) has shown 

that additional maintenance and inspection 

instructions are necessary to maintain the 

design features required to preclude the 

existence or development of an ignition 

source within the fuel tanks of the airplane. 

* * * * * 

The corrective action is revising the 

Airworthiness Limitations Section (ALS) of 

the Instructions for Continued Airworthiness 

(ICA) to incorporate new limitations for fuel 

tank systems. 

Restatement of Requirements of AD 2008– 

13–15 

Actions and Compliance 

(f) Unless already done, do the following 

actions. 

(1) Before December 16, 2008, revise the 

ALS of the ICA to incorporate Section A2.5.2, 

Fuel System Limitation Items, of Appendix 2 

of EMBRAER Legacy BJ—Maintenance

paragraph (h) of this AD. 

Explanation of CDCCL Requirements 

Note 2: Notwithstanding any other 

maintenance or operational requirements, 

components that have been identified as 

airworthy or installed on the affected 

airplanes before the revision of the ALS of 

the ICA, as required by paragraph (f)(3) of 

this AD, do not need to be reworked in 

accordance with the CDCCLs. However, once 

the ALS of the ICA has been revised, future 

maintenance actions on these components 

must be done in accordance with the 

CDCCLs. 

FAA AD Differences 

Note 3: This AD differs from the MCAI 

and/or service information as follows: 

(1) Brazilian Airworthiness Directive 2009– 

08–03, effective August 20, 2009, specifies 

that actions accomplished before the effective 

date of that AD, in accordance with Parker 

Service Bulletin 367–934–28–110, Revision 

A, dated December 19, 2006, are considered 

acceptable for compliance with the 

corresponding actions specified in the AD. 

This AD specifies that actions accomplished 

in accordance with applicable Parker CMM 

listed in Table 2 of this AD are considered 

acceptable for compliance. 

(2) The applicability of Brazilian 

Airworthiness Directive 2009–08–03, 

effective August 20, 2009, includes models 

other than Model EMB–135BJ airplanes. 

However, this AD does not include those 

other models. Those models are included in 

the applicability of FAA AD 2008–13–14, 

Amendment 39–15577. We are considering 

further rulemaking to revise AD 2008–13–14. 

(3) Although Brazilian Airworthiness 

Directive 2009–08–03, effective August 20, 

2009, specifies both revising the 

airworthiness limitations and repetitively 

inspecting, this AD only requires the 

revision. Requiring a revision of the 

airworthiness limitations, rather than 

requiring individual repetitive inspections, 

requires operators to record AD compliance 

status only at the time they make the 

revision, rather than after every inspection. 

Repetitive inspections specified in the 

airworthiness limitations must be complied 

with in accordance with 14 CFR 91.403(c). 

Other FAA AD Provisions 

(h) The following provisions also apply to 

this AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, International 

Branch, ANM–116, FAA, has the authority to 

approve AMOCs for this AD, if requested 

using the procedures found in 14 CFR 39.19. 

Send information to ATTN: Todd Thompson, 

Aerospace Engineer, International Branch, 

ANM–116, Transport Airplane Directorate, 

FAA, 1601 Lind Avenue, SW., Renton, 

Washington 98057–3356; telephone (425) 

227–1175; fax (425) 227–1149. Before using 

any approved AMOC on any airplane to 

which the AMOC applies, notify your 

principal maintenance inspector (PMI) or 

principal avionics inspector (PAI), as 

appropriate, or lacking a principal inspector, 

your local Flight Standards District Office. 

The AMOC approval letter must specifically 

reference this AD. 

(2) Airworthy Product: For any requirement 

in this AD to obtain corrective actions from 

a manufacturer or other source, use these 

actions if they are FAA-approved. Corrective 

actions are considered FAA-approved if they 

are approved by the State of Design Authority 

(or their delegated agent). You are required 

to assure the product is airworthy before it 

is returned to service. 

(3) Reporting Requirements: For any 

reporting requirement in this AD, under the 

provisions of the Paperwork Reduction Act 

(44 U.S.C. 3501 et seq.), the Office of 

Management and Budget (OMB) has 

approved the information collection 

requirements and has assigned OMB Control 

Number 2120–0056.

ACTION: Supplemental notice of 

proposed rulemaking (NPRM); 

reopening of comment period. 

SUMMARY: We are revising an earlier 

NPRM for the products listed above that 

would supersede an existing AD. This 

action revises the earlier NPRM by 

expanding the scope. 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 earlier MCAI, Brazilian 

Airworthiness Directive 2007–08–02, 

effective September 27, 2007, describes 

the unsafe condition as: 

Fuel system reassessment, performed 

according to RBHA–E88/SFAR–88
