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 airplanes. This proposed AD was 
prompted by

[[Page 17462]]

reports of ``BLEED 1(2) LEAK'' messages displayed on the Engine 
Indication and Crew Alert System (EICAS), and indirect damage to 
components of the Electrical Wiring Interconnection System (EWIS) in 
the engine pylon area. This proposed AD would require inspecting the 
EWIS components for damage, and repair if necessary. This proposed AD 
would also require installing pre-cooler deflectors on the left- and 
right-hand pylons, and applying silicone sealant. We are proposing this 
AD to prevent indirect damage to EWIS components near the engine bleed 
air pre-coolers, which could result in a dual engine roll back to idle 
and consequent dual engine power loss and reduced controllability of 
the airplane.

DATES: We must receive comments on this proposed AD by May 12, 2014.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Discussion

    The Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC), 
which is the aviation authority for Brazil, has issued Brazilian 
Airworthiness Directive 2013-11-01, effective November 4, 2013 
(referred to after this as the Mandatory Continuing Airworthiness 
Information, or ``the MCAI''), to correct an unsafe condition for 
certain Embraer S.A. Model ERJ 170 airplanes. The MCAI states:

    This [ANAC] AD results from reports of ``BLEED 1(2) LEAK'' 
messages being displayed on the Engine Indication and Crew Alert 
system (EICAS) panel, and indirect damages to components of the 
Electrical Wiring Interconnection System (EWIS) on the engine pilone 
area, zones 419 and 429, adjacent to the exhaust flange of the 
engine bleed air precooler.
    Further investigation has shown that a leakage on the flange of 
the precooler refrigerating air exhaust duct caused the damage and 
triggered the message. We are issuing this [ANAC] AD to prevent EWIS 
components indirect damage, near to engine bleed air precooler, 
which could result in a dual engine roll back to idle and the 
consequent dual engine power loss.

Required actions include inspecting the EWIS components adjacent to the 
left- and right-hand pre-cooler for damage, and repair if necessary; 
installing pre-cooler deflectors on the left- and right-hand pylons, 
and applying silicone sealant. You may examine the MCAI in the AD 
docket on the Internet at http://www.regulations.gov by searching for 
and locating Docket No. FAA-2014-0172.

Relevant Service Information

    Embraer has issued EMBRAER Service Bulletin 170-36-0019, dated 
August 23, 2011; and Subject 20-62-00, ``Requirements for EWIS 
Components Inspections and Checks--Maintenance Practices'' of EMBRAER 
170/175/190/195 Standard Wiring Practices Manual SWPM-1590, Revision 
25, dated June 3, 2013. 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.

Costs of Compliance

    We estimate that this proposed AD would affect 181 products of U.S. 
registry.
    We also estimate that it would take about 6 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 about $366 
per product. Based on these figures, we estimate the cost of the 
proposed AD on U.S. operators to be $158,556, or $876 per product.
    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this proposed 
AD.

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

[[Page 17463]]

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.
