Federal Register / Vol. 73, No. 89 / Wednesday, May 7, 2008 / Proposed Rules 25609 

inspections, intervals, or CDCCLs are part of 

a later revision of Appendix 2 of the MPG 

that is approved by the Manager, ANM–116, 

FAA, or ANAC (or its delegated agent); or 

unless the inspections, intervals, or CDCCLs 

are approved as an alternative method of 

compliance (AMOC) in accordance with the 

procedures specified in paragraph (g) 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. 

Other FAA AD Provisions 

(g) 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) 

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. 

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 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 May 27, 2008. 

ADDRESSES: You may send comments by 

any of the following methods:

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 

February 21, 2008 (73 FR 9497). That 

earlier NPRM proposed to require 

actions intended to address the unsafe 

condition for the products listed above. 

Since that earlier NPRM was issued, 

we have determined that for certain 

airplanes the initial compliance times 

for doing the tasks specified in 

paragraph (f)(2) of the earlier NPRM 


rwilkins on PROD1PC63 with PROPOSALS
25610 Federal Register / Vol. 73, No. 89 / Wednesday, May 7, 2008 / Proposed Rules 

must be reduced. That earlier NPRM 

resulted from Brazilian Airworthiness 

Directive 2007–08–02, effective 

September 27, 2007 (referred to after 

this as ‘‘the MCAI’’). 

The MCAI does not provide an initial 

compliance time for doing the tasks. In 

the original NPRM, we proposed an 

initial compliance time that started from 

the effective date of the AD; or the date 

of issuance of the original Brazilian 

standard airworthiness certificate or the 

date of issuance of the original Brazilian 

export certificate of airworthiness; 

whichever occurs later. Although 

unstated in the MCAI, we have 

determined that the intent of the MCAI 

is for the initial compliance time to start 

from the initial delivery date of the 

airplane in order to address the 

identified unsafe condition in a timely 

manner. We have also revised the initial 

compliance times for clarity by 

providing a threshold and grace period 

for each task. We have revised this 

supplemental NPRM by adding Table 1 

to specify the initial compliance times 

for each task. You may obtain further 

information by examining the MCAI in 

the AD docket. 

Comments 

We have considered the following 

comments received on the earlier 

NPRM. 

Request To Clarify Compliance Times 

EMBRAER and ExpressJet request that 

we revise the NPRM to include 

paragraph (section) A2.5.1 of Appendix 

2 of EMBRAER EMB–135/ERJ–140/ 

EMB–145 Maintenance Review Board 

Report (MRBR) MRB–145/1150, 

Revision 10, dated August 4, 2006. The 

commenters assert that paragraph 

A2.5.1 contains provisions to allow 

operators to implement the required fuel 

system limitation inspections in a 

timely manner. ExpressJet asserts that 

without the inclusion of paragraph 

A2.5.1, operators will be non-compliant 

with the AD immediately upon the 

inclusion of paragraph A.2.5.2 into the 

maintenance programs. Finally, 

ExpressJet asserts that operators will not 

have sufficient spare parts and states 

that they have been informed that the 

manufacturer of replacement parts 

required by these new limitations will 

be unable to meet the demand, which 

could lead to immediate grounding of 

airplanes. The commenters therefore 

request that we revise the NPRM to 

include paragraph A2.5.1 of the MRBR 

so operators are able to comply with the 

AD in an achievable time frame. 

We do not agree with this request to 

include MRBR paragraph A2.5.1, which 

describes deferring the first mandatory 

inspections to the next ‘‘C’’ check (5,000 

flight hours). However, as described 

previously, we have revised the initial 

compliance times specified in paragraph 

(f)(2) of the supplemental NPRM. With 

these revised compliance times, there 

should be sufficient spare parts. In 

addition, if an operator decides that 

more compliance time is needed, the 

operator may request an alternative 

method of compliance (AMOC) in 

accordance with paragraph (g)(1) of the 

supplemental NPRM. 

New Service Information 

Since the NPRM was issued, we have 

reviewed sections A2.5.2, Fuel System 

Limitation Items, and A2.4, Critical 

Design Configuration Control Limitation 

(CDCCL), of Appendix 2 of the 

EMBRAER EMB–135/ERJ–140/EMB–

145 MRBR MRB–145/1150, Revision 11, 

dated September 19, 2007 (we referred 

to the EMBRAER EMB–135/ERJ–140/ 

EMB–145 MRBR MRB–145/1150, 

Revision 10, dated August 4, 2006, as 

the appropriate source of service 

information for doing the actions 

specified in the NPRM). No changes 

were made to the tasks specified in the 

MRBR. We have revised this AD to refer 

to Revision 11 of the MRBR. 

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 704 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 

$56,320, 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

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 adding 

the following new AD: 

Empresa Brasileira De Aeronautica S.A. 

(Embraer): Docket No. FAA–2008–0182; 

Directorate Identifier 2007–NM–262–AD. 

Comments Due Date 

(a) We must receive comments by May 27, 

2008. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to EMBRAER Model 

EMB–135ER, –135KE, –135KL, and –135LR 

airplanes, and Model EMB–145, –145ER, 

–145MR, –145LR, –145XR, –145MP, and 

–145EP airplanes; certificated in any 

category; except for Model EMB–145LR 

airplanes modified according to Brazilian 

Supplemental Type Certificate 2002S06–09, 

2002S06–10, or 2003S08–01. 

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 (g) 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. 

Actions and Compliance 

(f) Unless already done, do the following 

actions. 

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

means the EMBRAER EMB–135/ERJ–140/ 

EMB–145 Maintenance Review Board Report 

(MRBR) MRB–145/1150, Revision 11, dated 

September 19, 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 MRBR. For all tasks identified in 

section A2.5.2 of Appendix 2 of the MRBR, 

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 MRBR, except as provided by paragraphs 

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

FAA AD Differences 

Note 2: This AD differs from the MCAI 

and/or service information as follows: 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. 

Other FAA AD Provisions 

(g) 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) 

has approved the information collection 

requirements and has assigned OMB Control 

Number 2120–0056.

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) 

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: 

Following in-flight test deployments, 

several Air-Driven generators (ADGs) failed 

to come on-line. Investigation revealed that, 

as a result of a wiring anomaly that had not 

been detected during ADG manufacture, a 

short circuit was possible between certain 

internal wires and their metallic over-braided 

shields, which could result in the ADG not 

providing power when deployed. * * *
