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

ACTION: Final rule.

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

SUMMARY: We are adopting a new 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 possibility of missing points of sealant 
application on the vapor barrier assembly in the wing stub rear box. 
In the event of fuel tank leak in this region associated with an 
unsealed vapor barrier assembly, migration of flammable vapors and 
fluids to middle electronic bay may occur, which then could lead to 
an uncontained fire event if the flammable vapors finds an ignition 
source.
* * * * *

We are issuing this AD to require actions to correct the unsafe 
condition on these products.

DATES: This AD becomes effective May 19, 2010.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of May 19, 2010.

ADDRESSES: You may examine the AD docket on the Internet at http://
www.regulations.gov or in person at the U.S. Department of 
Transportation, Docket Operations, M-30, West Building Ground Floor, 
Room W12-140, 1200 New Jersey Avenue, SE., Washington, DC.

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 January 5, 2010 (75 
FR 260). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    It has been found the possibility of missing points of sealant 
application on the vapor barrier assembly in the wing stub rear box. 
In the event of fuel tank leak in this region associated with an 
unsealed vapor barrier assembly, migration of flammable vapors and 
fluids to middle electronic bay may occur, which then could lead to 
an uncontained fire event if the flammable vapors finds an ignition 
source.
* * * * *

The required actions include a detailed inspection for gaps, voids, or 
holes in the sealant. Corrective actions include applying sealant into 
any gaps, voids, or holes. You may obtain further

[[Page 19202]]

information by examining the MCAI in the AD docket.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the single comment received.

Request To Change Paragraph Reference

    The manufacturer, EMBRAER, requests that we revise paragraph (g)(3) 
of the NPRM to refer to the inspection specified in paragraph (g)(1) of 
the NPRM rather than paragraph (f)(1) as stated in the NPRM, because 
the inspection is required by paragraph (g)(1) of the NPRM.
    We agree to revise paragraph (g)(3) of the AD to refer to paragraph 
(g)(1) of the AD. Paragraph (f)(1) of this AD does not exist and 
paragraph (f) has no inspection requirement; paragraph (g)(1) of this 
AD contains the AD's only inspection requirement. We have changed 
paragraph (g)(3) of the AD accordingly.

Conclusion

    We reviewed the available data, including the comment received, and 
determined that air safety and the public interest require adopting the 
AD with the change described previously. We determined that this change 
will not increase the economic burden on any operator or increase the 
scope of the 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 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.

Explanation of Change to Costs of Compliance

    Since issuance of the NPRM, we have increased the labor rate used 
in the Costs of Compliance from $80 per work-hour to $85 per work-hour. 
The Costs of Compliance information, below, reflects this increase in 
the specified hourly labor rate.

Costs of Compliance

    We estimate that this AD will affect about 197 products of U.S. 
registry. We also estimate that it will take about 5 work-hours per 
product to comply with the basic requirements of this AD. The average 
labor rate is $85 per work-hour. Based on these figures, we estimate 
the cost of this AD to the U.S. operators to be $83,725, or $425 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.

assembly, migration of flammable vapors and fluids to middle 
electronic bay may occur, which then could lead to an uncontained 
fire event if the flammable vapors finds an ignition source.
* * * * *
The required actions include a detailed inspection for gaps, voids, 
or holes in the sealant. Corrective actions include applying sealant 
into any gaps, voids, or holes.

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 6,000 flight hours or 24 months after the effective 
date of this AD, whichever occurs first, do a detailed inspection of 
the vapor barrier assembly in the wing stub rear box for missing 
sealant which forms gaps, voids or holes, in accordance with the 
Accomplishment Instructions of EMBRAER Service Bulletin 170-57-0036, 
dated March 13, 2009 (for Model ERJ 170-100 LR, -100 STD, -100 SE, -
100 SU, -200 LR, -200 STD, and -200 SU airplanes); or EMBRAER 
Service Bulletin 190-57-0027, dated March 18, 2009 (for Model ERJ
