Airworthiness Directives; Empresa Brasileira de 
Aeron[aacute]utica S.A. (EMBRAER) Model ERJ 170 and ERJ 190 Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are superseding an existing airworthiness directive (AD) 
for the products listed above. This 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:

    It has been found the occurrence of two events of aircraft being 
dispatched with the cargo door opened without indication. In one of 
the events the aircraft took off with the cargo door opened.
* * * * *
    The unsafe condition is a cargo door opening during flight, which 
could result in reduced structural integrity and consequent rapid 
decompression of the airplane. We are issuing this AD to require 
actions to correct the unsafe condition on these products.

DATES: This AD becomes effective December 17, 2009.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of December 17, 
2009.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM was published in the Federal Register on August 18, 2009 (74 
FR 41642), and proposed to supersede AD 2007-06-53, Amendment 39-15035 
(72 FR 21088, April 30, 2007). That NPRM proposed to correct an unsafe 
condition for the specified products. The MCAI states:

    It has been found the occurrence of two events of aircraft being 
dispatched with the cargo door opened without indication. In one of 
the events the aircraft took off with the cargo door opened.

    The unsafe condition is a cargo door opening during flight, which 
could result in reduced structural integrity and consequent rapid 
decompression of the airplane. Required actions include repetitive 
inspections of the forward and aft cargo doors to detect signs of 
interference between the lock handle and the aft edge liner assembly 
and

[[Page 58192]]

reworking the assembly; a one-time inspection for signs of damage of 
the lateral roller fitting on the forward and aft cargo door frames at 
the fuselage and replacement of the roller if necessary, and 
modification of the cargo door, which ends the repetitive inspections. 
After accomplishing the modification, the actions include incorporating 
information into the maintenance program to include the operational 
(OPC) and functional (FNC) checks of the forward and aft cargo doors 
and accomplishing repetitive OPC and FNC checks. You may obtain further 
information by examining the MCAI in the AD docket.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting the AD as proposed.

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 required different actions in this AD from those 
in the MCAI in order to follow our FAA policies. Any such differences 
are highlighted in a Note within the AD.

Costs of Compliance

    We estimate that this AD will affect about 145 products of U.S. 
registry.
    The actions that are required by AD 2007-06-53 and retained in this 
AD take about 1 work-hour per product, at an average labor rate of $80 
per work hour. Based on these figures, the estimated cost of the 
currently required actions is $80 per product.
    We estimate that it would take about 7 work-hours per product to 
comply with the new basic requirements of this AD. The average labor 
rate is $80 per work-hour. Required parts will cost about $17,162 per 
product. Where the service information lists required parts costs that 
are covered under warranty, we have assumed that there will be no 
charge for these costs. As we do not control warranty coverage for 
affected parties, some parties may incur costs higher than estimated 
here. Based on these figures, we estimate the cost of the AD on U.S. 
operators to be $2,569,690, or $17,722 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 AD will not have federalism implications 
under Executive Order 13132. This AD will 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 AD:
    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 AD and placed it in the AD docket.

Examining the AD Docket

    You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Operations office 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The AD docket contains the NPRM, the regulatory evaluation, 
any comments received, and other information. The street address for 
the Docket Operations office (telephone (800) 647-5527) is in the 
ADDRESSES section. Comments will be available in the AD docket shortly 
after receipt.

    Note 4: For the purposes of this AD, a functional check (FNC) 
is: ``A quantitative check to determine if one or more functions of 
an item perform within specified limits.''


    Note 5:  For the purposes of this AD, an operational check (OPC) 
is: ``A task to determine if an item is fulfilling its intended 
purpose. Since it is a failure finding task, it does not require 
quantitative tolerances.''

FAA AD Differences

    Note 6:  This AD differs from the MCAI and/or service 
information as follows: Where the MCAI includes a compliance time of 
``after accomplishment of the modification'' for revising the 
maintenance program for Model ERJ-170 airplanes, we have determined 
that a compliance time of ``within 12 months after the effective 
date of the AD or within 12 months after accomplishment of the 
modification, whichever occurs later'' is appropriate. This 
compliance time is equivalent to the compliance time required for 
Model ERJ-190 airplanes. The manufacturer and ANAC agree with this 
compliance time.

Other FAA AD Provisions

    (l) The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Branch, 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, FAA, Transport Airplane Directorate, 
1601 Lind Avenue, SW., Renton, Washington 98055-4056; 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. The AMOC approval letter must 
specifically reference this AD. AMOCs approved previously in 
accordance with AD 2007-06-53, are approved as AMOCs for the 
corresponding provisions of paragraph (i) of 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.
