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:

    [T]he occurrence of drill marks [has been found] at the lower 
ring region of the rear pressure bulkhead between [the] 
circumferential splice joint and rear skin located between stringers 
12 and 13. These marks may result in formation of fatigue cracks 
accelerated by corrosion reducing the structural strength of the 
rear pressure bulkhead, which may cause a sudden decompression of 
the passenger cabin.
* * * * *
We are issuing this AD to require actions to correct the unsafe 
condition on these products.

DATES: This AD becomes effective June 15, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of June 15, 
2011.

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 February 10, 2011 
(76 FR 7511). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    [T]he occurrence of drill marks [has been found] at the lower 
ring region of the rear pressure bulkhead between [the] 
circumferential splice joint and rear skin located between stringers 
12 and 13. These marks may result in formation of fatigue cracks 
accelerated by corrosion reducing the structural strength of the 
rear pressure bulkhead, which may cause a sudden decompression of 
the passenger cabin.
* * * * *
    The required actions include doing a detailed inspection for signs 
of drill marks and repairing if necessary. 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.

[[Page 27238]]

Costs of Compliance

    We estimate that this AD will affect 241 products of U.S. registry. 
We also estimate that it will take about 1 work-hour 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 $20,485, or $85 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 2 work-hours and require parts costing $20, for a cost of 
$190 per product. We have no way of determining the number of products 
that may need these actions.

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.

Subject

    (d) Air Transport Association (ATA) of America Code 53: 
Fuselage.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:

    [T]he occurrence of drill marks [has been found] at the lower 
ring region of the rear pressure bulkhead between [the] 
circumferential splice joint and rear skin located between stringers 
12 and 13. These marks may result in formation of fatigue cracks 
accelerated by corrosion reducing the structural strength of the 
rear pressure bulkhead, which may cause a sudden decompression of 
the passenger cabin.
* * * * *

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) Before the accumulation of 20,000 flight cycles, do a 
detailed inspection for signs of drill marks at the left and right 
lower ring region of the rear pressure bulkhead between the 
circumferential splice joint and rear skin between stringers 12 and 
13, in accordance with EMBRAER Service Bulletin 170-53-0082 or 190-
53-0042, both Revision 01, both dated April 28, 2010, as applicable. 
If drill marks are found, repair before further flight, in 
accordance with EMBRAER Service Bulletin 170-53-0082 or 190-53-0042, 
both Revision 01, both dated April 28, 2010, as applicable.

    Note 1:  For the purposes of this AD, a detailed inspection is: 
``An intensive examination of a specific item, installation, or 
assembly to detect damage, failure, or irregularity. Available 
lighting is normally supplemented with a direct source of good 
lighting at an intensity deemed appropriate. Inspection aids such as 
mirror, magnifying lenses, etc., may be necessary. Surface cleaning 
and elaborate procedures may be required.''

FAA AD Differences

    Note 2:  This AD differs from the MCAI and/or service 
information as follows:
    Although EMBRAER Service Bulletins 170-53-0082 and 190-53-0042, 
both Revision 01, both dated April 28, 2010, specify doing a general 
visual inspection, this AD requires doing a detailed inspection.
