FAA AD Differences 

Note 2: This AD differs from the MCAI 

and/or service information as follows: 

(1) The MCAI specifies a compliance date 

of ‘‘Before December 31, 2008’’ for doing the 

ALI revisions. We have already issued 

regulations that require operators to revise 

their maintenance/inspection programs to 

address fuel tank safety issues. The 

compliance date for these regulations is 

December 16, 2008. To provide for 

coordinated implementation of these 

regulations and this AD, we are using this 

same compliance date in this AD. 

(2) EMBRAER EMB135/ERJ140/EMB145 

Maintenance Review Board Report MRB– 

145/1150, Revision 11, dated September 19, 

2007, specifies compliance times to do tasks 

28–41–01–720–001–A00 and 28–41–04–720– 

001–A00 for certain components based on 

flight hours of the airplane. This AD requires 

that the tasks be done at compliance times 

based on flight hours of the component. 

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.

any approved AMOC on any airplane to 

which the AMOC applies, notify your 

appropriate principal inspector (PI) in the 

FAA Flight Standards District Office (FSDO), 

or lacking a PI, your local FSDO. 

(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, 

the Office of Management and Budget (OMB)

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: 

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. * * * 

The proposed AD would require actions 

that are intended to address the unsafe 

condition described in the MCAI. 

DATES: We must receive comments on 

this proposed AD by November 17, 

2008. 

ADDRESSES: You may send comments by 

any of the following methods:

relevant data, views, or arguments about 

this proposed AD. Send your comments 

to an address listed under the 

ADDRESSES section. Include ‘‘Docket No. 

FAA–2008–1080; Directorate Identifier 

2008–NM–118–AD’’ at the beginning of 

your comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this proposed AD. We will 

consider all comments received by the 

closing date and may amend this 

proposed AD based on those comments. 

We will post all comments we

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact we receive 

about this proposed AD. 

Discussion 

On June 13, 2008, we issued AD 

2008–13–15, Amendment 39–15578 (73 

FR 35908, June 25, 2008). That AD 

requires actions intended to address an 

unsafe condition on the products listed 

above. 

The preamble to AD 2008–13–15 

explains that we were considering 

further rulemaking to address tasks 28– 

41–01–720–001–A00 and 28–46–05– 

720–001–A00 because the tasks are 

related to a functional check of the 

component rather than the aircraft 

system. Those tasks are specified in 

EMBRAER Legacy BJ—Maintenance 

Planning Guide MPG–1483, Revision 5, 

dated March 22, 2007 (which we 

referred to as the appropriate source of 

service information for the existing AD). 

We now have determined that further 

rulemaking is indeed necessary, and 

this proposed AD follows from that 

determination. We have proposed to 

require those tasks with compliance 

times based on the component flight 

hours in paragraph (g) of this proposed 

AD. 

Removed Reference to ‘‘Later 

Revisions’’ of Service Information 

We removed the reference to ‘‘later 

revisions’’ of the applicable service 

information in paragraph (f)(4) of this 

AD to be consistent with FAA policy 

and Office of the Federal Register 

regulations. We might consider 

approving the use of later revisions of 

the service information as an alternative 

method of compliance with this AD, as 

provided by paragraph (h)(1) of this AD. 

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 41 products of U.S. registry. 

We also estimate that it would take 

about 1 work-hour per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $80 per work-hour. Based on 

these figures, we estimate the cost of the 

proposed AD on U.S. operators to be 

$3,280, or $80 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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, 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 

November 17, 2008. 

Affected ADs 

(b) The proposed AD supersedes AD 2008– 

13–15, Amendment 39–15578. 


ebenthall on PROD1PC60 with PROPOSALS
Federal Register / Vol. 73, No. 201 / Thursday, October 16, 2008 / Proposed Rules 61377 

Applicability 

(c) This AD applies to all 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) 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) states: 

Fuel system reassessment, performed 

according to RBHA–E88/SFAR–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. * * * 

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 

(f) Unless already done, do the following 

actions. 

(1) The term ‘‘MPG,’’ as used in this AD, 

means the EMBRAER Legacy BJ— 

Maintenance Planning Guide (MPG) MPG– 

1483, Revision 5, dated March 22, 2007. 

(2) Before December 16, 2008, revise the 

ALS of the ICA to incorporate Section A2.5.2, 

Fuel System Limitation Items, of Appendix 2 

of the MPG. Except as required by paragraph 

(g) of this AD, for all tasks identified in 

Section A2.5.2 of Appendix 2 of the MPG, 

the initial compliance times start from the 

applicable times specified in Table 1 of this 

AD; and the repetitive inspections must be 

accomplished thereafter at the interval 

specified in Section A2.5.2 of Appendix 2 of 

the MPG, except as provided by paragraphs 

(f)(4) and (h) of this AD.

FAA AD Differences 

Note 2: This AD differs from the MCAI 

and/or service information as follows: 

(1) The MCAI specifies a compliance date 

of ‘‘Before December 31, 2008’’ for doing the 

ALI revisions. We have already issued 

regulations that require operators to revise 

their maintenance/inspection programs to 

address fuel tank safety issues. The 

compliance date for these regulations is 

December 16, 2008. To provide for 

coordinated implementation of these 

regulations and this AD, we are using this 

same compliance date in this AD. 

(2) The MCAI specifies a compliance time 

of 180 days to revise the ALS of the ICA to 

incorporate items 1, 2, and 3 of Section A2.4 

of Appendix 2 of the MPG. This AD requires 

a compliance time of 90 days to do this 

revision. This difference has been 

coordinated with ANAC. 

(3) EMBRAER Legacy BJ—Maintenance 

Planning Guide MPG–1483, Revision 5, dated 

March 22, 2007, specifies compliance times 

to do tasks 28–41–01–720–001–A00 and 28– 

46–05–720–001–A00 for certain components 

based on flight hours of the airplane. This AD 

requires that the tasks be done at compliance 

times based on flight hours of the 

component. 

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.

any approved AMOC on any airplane to 

which the AMOC applies, notify your 

appropriate principal inspector (PI) in the 

FAA Flight Standards District Office (FSDO), 

or lacking a PI, your local FSDO. 

(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

Airworthiness Directives; Boeing 

Model 767 Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Supplemental notice of 

proposed rulemaking (NPRM); 

reopening of comment period. 

SUMMARY: We are revising an earlier 

proposed airworthiness directive (AD) 

for certain Boeing Model 767 airplanes. 

The original NPRM would have 

required sealing certain fasteners and 

stiffeners in the fuel tank, and changing 

certain wire bundle clamp 

configurations on the fuel tank walls. 

The original NPRM resulted from fuel 

system reviews conducted by the 

manufacturer. This action revises the 

original NPRM by adding inspections, 

for certain airplanes, of additional 

fasteners in the fuel tanks and of the 

method of attachment of the vortex 

generators, and corrective action if 

necessary. We are proposing this 

supplemental NPRM to prevent possible 

ignition sources in the auxiliary fuel 

tank, main fuel tanks, and surge tanks 

caused by a wiring short or lightning
