(EMBRAER) Model ERJ 170 and ERJ 190 Airplanes

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 cases where the pressure equalization valve 
was not installed in the left-hand bulkhead blowout panel, on the 
forward and/or aft cargo compartments, thus affecting the 
effectiveness of fire detection, containment and suppression.

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

DATES: This AD becomes effective October 14, 2008.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of October 14, 
2008.

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 May 20, 2008 (73 FR 
29085). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    It has been found cases where the pressure equalization valve 
was not installed in the left-hand bulkhead blowout panel, on the 
forward and/or aft cargo compartments, thus affecting the 
effectiveness of fire detection, containment and suppression.

Corrective actions include inspecting for the presence of pressure 
equalization valves and, if necessary, installing pressure equalization 
valves. 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 101 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 $80 per work-hour. Based on these figures, we estimate 
the cost of this AD to the U.S. operators to be $8,080, or $80 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.

any category.

Subject

    (d) Air Transport Association (ATA) of America Code 21: Air 
Conditioning.

Reason

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

    It has been found cases where the pressure equalization valve 
was not installed in the left-hand bulkhead blowout panel, on the 
forward and/or aft cargo compartments, thus affecting the 
effectiveness of fire detection, containment and suppression.

Corrective actions include inspecting for the presence of pressure 
equalization valves and, if necessary, installing pressure 
equalization valves.

Actions and Compliance

    (f) Unless already done, do the following actions.
    (1) Within 500 flight hours after the effective date of this AD, 
perform a general visual inspection on the left-hand bulkhead 
blowout panel of both the forward and aft cargo compartments to 
determine whether the pressure equalization valves, part number (P/
N) 120-48865-003, are installed. If both pressure equalization 
valves are installed in their respective blowout panels, no 
additional action is required by this AD.
    (2) If any valve is not installed, within 700 flight hours after 
the effective date of this AD, install valve P/N 120-48865-003, in 
accordance with the Accomplishment Instructions of EMBRAER Service 
Bulletin 170-21-0032 or 190-21-0019, both dated August 10, 2007; as 
applicable.

    Note 1: For the purpose of this AD, a general visual inspection 
(GVI) is: ``A visual examination of an interior or exterior area, 
installation or assembly to detect obvious damage, failure or 
irregularity. This level of inspection is made from within touching 
distance, unless otherwise specified. A mirror may be necessary to 
enhance visual access to all exposed surfaces in the inspection 
area. This level of inspection is made under normally available 
lighting conditions such as daylight, hangar lighting, flashlight or 
drop-light, and may require removal or opening of access panels or 
doors. Stands, ladders or platforms may be required to gain 
proximity to the area being checked.''

FAA AD Differences

    Note 2: This AD differs from the MCAI and/or service information 
as follows: No differences.
