Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2010-1310; Directorate Identifier 2010-NM-067-AD; 
Amendment 39-16786; AD 2011-18-04]
RIN 2120-AA64


Airworthiness Directives; Empresa Brasileira de Aeronautica 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 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 reported during operational checks that some 
failures of the Escape Slide * * * installed on the forward 
passenger and service door have occurred which prevented the door 
from opening.
    * * * [T]his condition * * * could delay an emergency evacuation 
and increase the chance of injury to passengers and flight crew * * 
*.

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

DATES: This AD becomes effective October 14, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of October 14, 
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.

FOR FURTHER INFORMATION CONTACT: Kenny Kaulia, Aerospace Engineer, 
International Branch, ANM-116, Transport Airplane Directorate, FAA,

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 13, 2011 (76 
FR 2279). That NPRM proposed to correct an unsafe condition for the 
specified products. MCAI Brazilian Airworthiness Directive 2009-11-01 
states:

    It has been reported during operational checks that some 
failures of the Escape Slide P/N [part number] 4A4030-2 and P/N 
4A4030-4 installed on the forward passenger and service door have 
occurred which prevented the door from opening.
    Since this condition * * * could delay an emergency evacuation 
and increase the chance of injury to passengers and flight crew, a 
corrective action is required.

MCAI Brazilian Airworthiness Directive 2009-08-02 states:

    It has been reported during operational checks some failures in 
the deployment of the Escape Slide P/N 104003-1 installed in the 
forward passenger and service door, preventing the door opening.
    Since this condition * * * could impede an emergency evacuation 
and increase the chance of injury to passengers and flight crew, a 
corrective action is required.

The required actions include modifying the escape slides of the forward 
passenger and service doors, and doing borescope inspections for damage 
of the aspirator body and inlet cross valve. Corrective actions include 
replacing the aspirator body. 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 considered the comments received.

Request To Delay the AD

    Goodrich requested that issuance of this AD be delayed until 
further notice pending completion of their ongoing investigations into 
the root cause of additional door stall events. The commenter 
anticipates that a reduced overhaul cycle might be required to mitigate 
future occurrences until a complete and final action is developed.
    We disagree with the request to delay the AD. To delay this action 
would be inappropriate, in light of the identified unsafe condition. We 
might consider additional rulemaking action, however, if we receive new 
information indicating the need to change the AD. We have not changed 
the AD in this regard.

Request To Expand the Applicability of the AD

    EMBRAER requested that post-modification part number (P/N) 4A4030-5 
for the ERJ 170, and P/N 104003-2 for the ERJ 190, be included in the 
Applicability, Actions, and Parts Installation paragraphs of the NPRM 
(paragraphs (c), (g), and (i) respectively). The commenter made this 
request in response to reports of door stall caused by the forward 
escape slide of those part numbers post-modification using the version 
of the Goodrich service information cited in the NPRM.
    We disagree with the request to add the part numbers. While we are 
aware of the reports of door stall caused by the forward escape slides 
with those other parts that had been modified per the Goodrich service 
information cited in the NPRM, we understand that the root cause of the 
door stall is still under investigation, as mentioned by the previous 
commenter. Further, we choose to not delay issuance of the AD as 
mentioned previously, because the known unsafe condition exists on the 
part numbers specified in the NPRM. When that investigation is complete 
we might take further rulemaking action. We have not changed the AD in 
this regard.

Conclusion

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

[[Page 55782]]

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 236 products of U.S. 
registry. We also estimate that it will take about 12 work-hours per 
product to comply with the basic requirements of this AD. The average 
labor rate is $85 per work-hour. Required parts will cost about $0 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 parts. 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 this AD to the 
U.S. operators to be $240,720, or $1,020 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.
