DEPARTMENT OF TRANSPORTATION

Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2014-0172; Directorate Identifier 2013-NM-222-AD; 
Amendment 39-17929; AD 2014-16-05]
RIN 2120-AA64


Airworthiness Directives; Embraer S.A. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Embraer S.A. Model ERJ 170 airplanes. This AD was prompted by 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 AD requires inspecting the EWIS components for damage, and 
repair if necessary. This AD also requires installing pre-cooler 
deflectors on the left- and right-hand pylons, and applying silicone 
sealant. We are issuing 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: This AD is effective October 2, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of October 2, 
2014.

ADDRESSES: You may examine the AD docket on the Internet at http://www.regulations.gov/#!docketDetail;D=FAA-2014-0172 or in person at the

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain Embraer S.A. Model 
ERJ 170 airplanes. The NPRM published in the Federal Register on March 
28, 2014 (79 FR 17461).
    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 [Brazilian] 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 [Brazilian] 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/#!docketDetail;D=FAA-2014-0172-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (79 FR 17461, March 28, 
2014) or on the determination of the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this AD with the changes described 
previously and minor editorial changes. We have determined that these 
minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (79 FR 17461, March 28, 2014) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (79 FR 17461, March 28, 2014).
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Costs of Compliance

    We estimate that this AD affects 181 airplanes of U.S. registry.
    We also estimate that it takes about 6 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour. Required parts cost about $366 per product. Based 
on these figures, we estimate the cost of the 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 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,

[[Page 51230]]

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

    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 that 
this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under 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.

    You may examine the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2014-
0172; or in person at the Docket Management Facility between 9 a.m. and
