Accomplishment Instructions of Airbus 

Mandatory Service Bulletin A330–71–3022 

(for Models A330–243, –341, –342, and –343 

airplanes) or A340–71–5004 (for Model 

A340–541 and –642 airplanes), both dated 

May 5, 2009. 

(1) For Model A330–243, –341, –342, and 

–343 airplanes: Within 4,500 flight cycles 

after the effective date of this AD. 

(2) For Model A340–541 and –642 

airplanes: Within 2,500 flight cycles after the 

effective date of this AD. 

(h) The actions specified in paragraph (g) 

of this AD are not required for any engine 

installed on the airplanes listed in paragraph 

(g)(1) of this AD, having serial number 964 

and subsequent; and the airplanes listed in 

paragraph (g)(2) of this AD, having serial 

number 981 and subsequent; if data records 

conclusively prove that this engine has not 

been replaced or re-installed since first flight 

of the airplane. 

(i) After the effective date of this AD, no 

person may install a Rolls Royce Trent 500 

or Trent 700 series engine on any airplane, 

unless it is in compliance with the 

requirements of this AD. 

(j) Although Airbus Mandatory Service 

Bulletins A330–71–3022 and A340–71–5004, 

both dated May 5, 2009, specify to submit 

certain information to the manufacturer, this 

AD does not include that requirement. 

FAA AD Differences 

Note 1: This AD differs from the MCAI 

and/or service information as follows: 

(1) The MCAI lists certain Airbus model 

A330–200 series and –300 series, and A340 

series airplanes. Airbus Mandatory Service 

Bulletins A330–71–3022 and A340–71–5004, 

both dated May 5, 2009, clarify this 

effectivity by adding ‘‘with Rolls-Royce Trent 

500 and Trent 700 series engines.’’ Airplanes 

with engines other than Rolls-Royce Trent 

500 and Trent 700 are not affected by this 

AD. 

(2) Although the MCAI or service 

information specifies submitting information 

to the manufacturer, paragraph (j) of this AD 

specifies that such submittal is not required. 

Other FAA AD Provisions 

(k) The following provisions also apply to 

this AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, International 

Branch, ANM–116, Transport Airplane 

Directorate, FAA, has the authority to 

approve AMOCs for this AD, if requested 

using the procedures found in 14 CFR 39.19.

(425) 227–1138; 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 FAAapproved 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.

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: During ERJ 170 airplane 

full scale fatigue test, cracks were found 

in some structural components of the 

airplane. Analysis of these cracks 

resulted in modifications on the 

airplane Airworthiness Limitation Items 

(ALI), to include new inspections tasks 

or modification of existing ones and its 

respective thresholds and intervals. 

Failure to inspect these components 

according to the new tasks, thresholds 

and intervals could prevent a timely 

detection of fatigue cracks. Undetected 

fatigue cracks in these areas could 

adversely affect the structural integrity 

of these airplanes. 

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 April 19, 2010.

Discussion 

The Ageˆncia Nacional de Aviac ̧a ̃o 

Civil (ANAC), which is the aviation 

authority for Brazil, has issued Brazilian 

Airworthiness Directive 2009–04–01, 

effective April 29, 2009 (referred to after 

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

condition for the specified products. 

The MCAI states: 

During ERJ 170 airplane full scale fatigue 

test, cracks were found in some structural 

components of the airplane. Analysis of these 

cracks resulted in modifications on the 

airplane Airworthiness Limitation Items 

(ALI), to include new inspections tasks or 

modification of existing ones and its 

respective thresholds and intervals. 

Failure to inspect these components 

according to the new tasks, thresholds and 

intervals could prevent a timely detection of 

fatigue cracks. Undetected fatigue cracks in 

these areas could adversely affect the 

structural integrity of these airplanes. 

* * * * * 

The corrective action is revising the 

Airworthiness Limitations Section of 

the Instructions for Continued 

Airworthiness to incorporate new 

structural inspection requirements. You 

may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

Embraer has issued temporary 

revisions to Appendix A—Part 2 of the 

Embraer 170 Maintenance Review Board 

Report MRB–1621, as identified in the 

following table. 

EMBRAER 170 TEMPORARY REVISIONS

Temporary 

revision Date 

TR 4–1 ............... October 15, 2007. 

TR 4–3 ............... December 6, 2007. 

TR 4–4 ............... January 18, 2008. 

The actions described in this service 

information are intended to correct the 

unsafe condition identified in the 

MCAI. 

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 166 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 $85 per work-hour. Based on 

these figures, we estimate the cost of the 

proposed AD on U.S. operators to be 

$14,110, 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 

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.

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part

Federal Register / Vol. 75, No. 42 / Thursday, March 4, 2010 / Proposed Rules 9813 

§ 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–2010– 

0176; Directorate Identifier 2009–NM– 

201–AD. 

Comments Due Date 

(a) We must receive comments by April 19, 

2010. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to all Empresa 

Brasileira de Aeronautica S.A. (EMBRAER) 

Model ERJ 170–100 LR, –100 STD, –100 SE, 

–100 SU, –200 LR, –200 STD, and –200 SU 

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. 

The FAA has provided guidance for this 

determination in Advisory Circular (AC) 25– 

1529–1A. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 53: Fuselage; 57: Wings. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

During ERJ 170 airplane full scale fatigue 

test, cracks were found in some structural 

components of the airplane. Analysis of these 

cracks resulted in modifications on the 

airplane Airworthiness Limitation Items 

(ALI), to include new inspections tasks or 

modification of existing ones and its 

respective thresholds and intervals. 

Failure to inspect these components 

according to the new tasks, thresholds and 

intervals, could prevent a timely detection of 

fatigue cracks. Undetected fatigue cracks in 

these areas could adversely affect the 

structural integrity of these airplanes. 

* * * * * 

The corrective action is revising the 

Airworthiness Limitations Section (ALS) of 

the Instructions for Continued Airworthiness 

to incorporate new structural inspection 

requirements. 

Compliance 

(f) You are responsible for having the 

actions required by this AD performed within 

the compliance times specified, unless the 

actions have already been done. 

Actions 

(g) Unless already done, do the following 

actions. 

(1) Within 90 days after the effective date 

of this AD revise the ALS of the Instructions 

for Continued Airworthiness (ICA) to 

incorporate the inspection tasks identified in 

the Embraer temporary revisions (TRs) to 

Appendix A—Part 2 of the Embraer 170 

Maintenance Review Board Report MRB– 

1621, listed in Table 1 of this AD. The initial 

compliance times for the tasks start from the 

applicable threshold times specified in the 

TRs for the corresponding tasks of the 

maintenance review board report or within 

500 flight cycles after the effective date of 

this AD, whichever occurs later. For certain 

tasks, the compliance times depend on the 

pre-modification and post-modification 

status of the actions specified in the 

associated service bulletin, as specified in the 

‘‘Applicability’’ column of the applicable TRs 

identified in Table 1 of this AD. The 

threshold values stated in the TRs referenced 

in Table 1 of this AD are total flight cycles 

on the airplane since the date of issuance of 

the original Brazilian airworthiness 

certificate or the date of issuance of the 

original Brazilian export certificate of 

airworthiness.

(or its delegated agent); or unless the 

inspection or interval is approved as an 

alternative method of compliance (AMOC) in 

accordance with the procedures specified in 

paragraph (h)(1) of this AD. 

FAA AD Differences 

Note 2: This AD differs from the MCAI 

and/or service information as follows: No 

differences. 

Other FAA AD Provisions 

(h) The following provisions also apply to 

this AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, International

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: During ERJ 190 airplane 

full scale fatigue test, cracks were found 

in some structural components of the 

airplane. Analysis of these cracks 

resulted in modifications on the 

airplane Airworthiness Limitation Items 

(ALI), to include new inspections tasks 

or modification of existing ones and its 

respective thresholds and intervals. 

Failure to inspect these components 

according to the new tasks, thresholds 

and intervals could prevent a timely 

detection of fatigue cracks. Undetected 

fatigue cracks in these areas could 

adversely affect the structural integrity 

of these airplanes. 

The proposed AD would require 

actions that are intended to address the 

unsafe condition described in the MCAI.

Discussion 

The Ageˆncia Nacional de Aviac ̧a ̃o 

Civil (ANAC), which is the aviation 

authority for Brazil, has issued Brazilian 

Airworthiness Directive 2009–04–02, 

effective April 29, 2009 (referred to after 

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

condition for the specified products. 

The MCAI states: 

During ERJ 190 airplane full scale fatigue 

test, cracks were found in some structural 

components of the airplane. Analysis of these 

cracks resulted in modifications on the 

airplane Airworthiness Limitation Items 

(ALI), to include new inspections tasks or 

modification of existing ones and its 

respective thresholds and intervals. 

Failure to inspect these components 

according to the new tasks, thresholds and 

intervals could prevent a timely detection of 

fatigue cracks. Undetected fatigue cracks in 

these areas could adversely affect the 

structural integrity of these airplanes. 

* * * * * 

The corrective action is revising the 

Airworthiness Limitations Section of 

the Instructions for Continued 

Airworthiness to incorporate new and 

modified structural inspections. You 

may obtain further information by 

examining the MCAI in the AD docket.
