Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. 
(EMBRAER) Model ERJ 190 Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the

[[Page 21286]]

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 routine inspection procedures on the wing assembly line 
it was identified the possibility of cracks and deformation 
developing during assembly on the internal wing spars and rib 
flanges, causing a safe[ty] margin reduction.
* * * * *
    The unsafe condition is cracking and deformation of wing spar and 
rib flanges, which could result in loss of structural integrity of the 
wing. 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 June 8, 2009.

Discussion

    The Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC), 
which is the aviation authority for Brazil, has issued Brazilian 
Airworthiness Directive 2008-10-03, effective October 21, 2008 
(referred to after this as ``the MCAI''), to correct an unsafe 
condition for the specified products. The MCAI states:

    During routine inspection procedures on the wing assembly line 
it was identified the possibility of cracks and deformation 
developing during assembly on the internal wing spars and rib 
flanges, causing a safe[ty] margin reduction.
* * * * *
    The unsafe condition is cracking and deformation of wing spar and 
rib flanges, which could result in loss of structural integrity of the 
wing. Corrective actions include performing a detailed inspection for 
damage on wing spar I, II, and III flanges and on certain rib flanges, 
and contacting ANAC (or its delegated agent) and Embraer for an 
approved repair. You may obtain further information by examining the 
MCAI in the AD docket.

Relevant Service Information

    Embraer has issued Service Bulletin 190-57-0023, dated June 9, 
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 27 products of U.S. registry. We also estimate that it 
would take 10 work-hours 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 $21,600, or $800 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,

[[Page 21287]]

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, 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.

Sec.  39.13  [Amended]

    2. The FAA amends Sec.  39.13 by adding the following new AD:

Empresa Brasileira de Aeronautica S.A. (Embraer): Docket No. FAA-
2009-0418; Directorate Identifier 2009-NM-020-AD.

Comments Due Date

    (a) We must receive comments by June 8, 2009.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to EMBRAER Model ERJ 190-100 ECJ, -100 LR, -
100 IGW, -100 STD, -200 STD, -200 LR, and -200 IGW airplanes, 
certificated in any category, serial numbers 19000002, 19000004, and 
19000006 through 19000062 inclusive.

Subject

    (d) Air Transport Association (ATA) of America Code 57: Wings.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    During routine inspection procedures on the wing assembly line 
it was identified the possibility of cracks and deformation 
developing during assembly on the internal wing spars and rib 
flanges, causing a safe[ty] margin reduction.
* * * * *
    The unsafe condition is cracking and deformation of wing spar 
and rib flanges, which could result in loss of structural integrity 
of the wing. Corrective actions include performing a detailed 
inspection for damage on wing spar I, II, and III flanges and on 
certain rib flanges, and contacting Ag[ecirc]ncia Nacional de 
Avia[ccedil][atilde]o Civil (ANAC) (or its delegated agent) and 
Embraer for an approved repair.

Actions and Compliance

    (f) Unless already done, do the following actions.
    (1) Before 5,000 total flight cycles on the airplane, or within 
1,000 flight cycles after the effective date of this AD, whichever 
occurs later: Perform a detailed inspection of the left and right 
wing rib and spars I, II, and III flanges, in accordance with the 
Accomplishment Instructions of Embraer Service Bulletin 190-57-0023, 
dated June 9, 2008.
    (2) If any cracking or deformation is detected during the 
inspection required by paragraph (f)(1) of this AD, before further 
flight, send the inspection results and request for repair 
instructions to ANAC (or its delegated agent) and Embraer Technical 
Support; e-mail structure@embraer.com.br; and do the repair.

FAA AD Differences

    Note 1:  This AD differs from the MCAI and/or service 
information as follows: Although the MCAI or service information 
allows further flight after cracks are found during compliance with 
the required action, paragraph (f)(2) of this AD requires that you 
repair the crack(s) before further flight.

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, Transport Airplane Directorate, 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: 
Kenny Kaulia, Aerospace Engineer, International Branch, ANM-116, 
Transport Airplane Directorate, FAA, 1601 Lind Avenue, SW., Renton, 
Washington 98057-3356; telephone (425) 227-2848; 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.
    (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.
