14 CFR Part 39

[Docket No. FAA-2008-0562; Directorate Identifier 2008-NM-010-AD]
RIN 2120-AA64

 
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. 
(EMBRAER) Model ERJ 170 and 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 
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:

    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.

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 19, 2008.

Discussion

    The Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC), 
which is the aviation authority for Brazil, has issued Brazilian 
Airworthiness Directives 2007-11-01 and 2007-11-02, both dated December 
12, 2007 (referred to after this as ``the MCAI''), 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 and, if 
necessary, installing pressure equalization valves. You may obtain 
further information by examining the MCAI in the AD docket.

Relevant Service Information

    Embraer has issued Service Bulletins 170-21-0032 and 190-21-0019, 
both dated August 10, 2007. 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 about 101 products of U.S. registry. We also estimate that 
it would take about 1 work-hour per product to

[[Page 29086]]

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 $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 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.

    Air transportation, Aircraft, Aviation safety, 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-
2008-0562; Directorate Identifier 2008-NM-010-AD.

Comments Due Date

    (a) We must receive comments by June 19, 2008.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Embraer Model ERJ 170-100 LR, -100 STD, -
100 SE, and -100 SU, -200 LR, -200 STD, and -200 SU airplanes, 
having serial numbers (S/N) 17000002, 17000004 through 17000013, and 
17000015 through 17000154; and Model ERJ 190-100 STD, -100 LR, -100 
IGW, -100 ECJ, -200 STD, -200 LR, and -200 IGW airplanes, having S/N 
19000002, 19000004, and 19000006 through 19000060; certificated in 
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 in 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 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.

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:

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 appropriate principal inspector (PI) in the FAA 
Flight Standards District Office (FSDO), or lacking a PI, your local 
FSDO.
    (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.
