Airworthiness Directives; Embraer S.A. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Embraer S.A. Model ERJ 170 and ERJ 190 airplanes. This proposed 
AD was prompted by reports of failures of the emergency slide on the 
forward passenger door, which prevented the door from opening. This 
proposed AD would require repetitive re-packing of certain forward door 
escape slides. We are proposing this AD to prevent failure of the 
emergency slide, preventing the forward passenger door from opening, 
which could result in impeded emergency evacuation and possible 
subsequent injury to passengers and flightcrew.

DATES: We must receive comments on this proposed AD by December 10, 
2012.

ADDRESSES: You may send comments by any of the following methods:
     Federal eRulemaking Portal: Go to http://www.regulations.gov. Follow the instructions for submitting comments.

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 2011-12-01 and 2011-12-02, both effective 
December 27, 2011 (referred to after this as ``the MCAI''), to correct 
an unsafe condition for the specified products. MCAI Brazilian 
Airworthiness Directive 2011-12-01 states:

    During operational checks of escape slide P/N 4A4030-5, some 
operators have reported failure in the escape slide preventing the 
forward passenger door opening. This [Brazilian] AD is being issued 
to prevent failure of this system which could impede an emergency 
evacuation and increase the chance of injury to passengers and 
flight crew.
* * * * *
MCAI Brazilian Airworthiness Directive 2011-12-02 states:

    During scheduled deployment tests of escape slide P/N 104003-2, 
some operators have reported failure in the escape slide preventing 
the forward passenger door opening. This [Brazilian] AD is being 
issued to prevent failure of this system which could impede an 
emergency evacuation and increase the chance of injury to passengers 
and flight crew.
* * * * *
The required action is repetitive re-packing of certain forward door 
escape slides. You may obtain further information by examining the MCAI 
in the AD docket.

Relevant Service Information

    Goodrich has issued Alert Service Bulletins 4A4030-25A402 and 
104003-25A403, both dated June 30, 2011. Embraer S.A. has issued 
Section 1 of EMBRAER 170 Maintenance Review Board Report, MRB-1621, 
Revision 7, dated November 11, 2010; and Section 1 of EMBRAER 190 
Maintenance Review Board Report, MRB-1928, Revision 5, dated November 
11, 2010. The actions described in this service information are 
intended to correct the unsafe condition identified in the MCAI.

[[Page 65145]]

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.

Difference Between the Service Information and This Proposed AD

    Where Goodrich Alert Service Bulletins 4A4030-25A402 and 104003-
25A403, both dated June 30, 2011, specify that Goodrich Service 
Bulletin 25-394 should be accomplished as a prior or concurrent action, 
this proposed AD would not require that service bulletin.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 253 products of U.S. registry. We also estimate that 
it would take about 2 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $85 per 
work-hour. Required parts would cost between $435 and $542 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 the proposed AD on U.S. 
operators to be between $153,065 and $180,136, or $605 and $712 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);
    3. Will not affect intrastate aviation in Alaska; and
    4. 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.
