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 chafing between the auxiliary power unit 
(APU) electronic starter controller (ESC) power cables and the airplane 
tail cone firewall. This proposed AD would require a detailed 
inspection for damage to the insulation and inner conductors of the APU 
ESC power cables, installing

[[Page 12257]]

new grommet support in the tail cone firewall, and corrective actions 
if necessary. We are proposing this AD to detect and correct damage to 
the APU ESC power cable harness, which if not corrected, could result 
in reduced structural integrity of the fuselage and empennage in the 
event of fire penetration through the firewall.

DATES: We must receive comments on this proposed AD by April 8, 2013.

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 2012-03-03 and 2012-03-04, both dated April 
13, 2012 (referred to after this as ``the MCAI''), to correct an unsafe 
condition for the specified products. The MCAI states:

    It has been found the occurrences of chafing between the 
Auxiliary Power Unit (APU) Electronic Starter Controller (ESC) power 
cables (harness W205) and the airplane tail cone firewall due to the 
grommet installed in the tail cone firewall moves out of its place. 
This condition, if not corrected, may result in reduced structural 
integrity of the fuselage and empennage in an event of fire 
penetration through the firewall.

The required actions include a detailed inspection for damage to the 
harness insulation and inner conductors of the APU ESC power cables, 
installing a new grommet support in the tail cone firewall, and 
corrective actions if necessary. Corrective actions include repairing 
the harness W205 insulation or replacing the harness W205 of the APU 
ESC power cables with a new harness. You may obtain further information 
by examining the MCAI in the AD docket.

Relevant Service Information

    Embraer has issued Service Bulletin 170-53-0093, Revision 01, dated 
March 16, 2012 (for Model ERJ 170 airplanes); Service Bulletin 190-53-
0054, Revision 01, dated March 16, 2012 (for Model ERJ 190 airplanes); 
and Service Bulletin 190LIN-53-0059, Revision 01, dated March 16, 2012 
(for Model ERJ 190-100 ECJ airplanes). 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

    Although Brazilian Airworthiness Directive AD 2012-03-04, dated 
April 13, 2012, specifies a compliance time of ``within 3,000 flight 
hours (FH)'' after the effective date of this AD for performing a 
detailed inspection on the APU ESC power cables for damage, this AD 
requires the action be done within 3,000 flight hours (FH) or 18 months 
after the effective date of this AD, whichever occurs first. This 
proposed compliance time aligns with the compliance time listed in 
Brazilian AD 2012-03-03, dated April 13, 2012.

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 15 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 $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 the proposed AD on U.S. operators to 
be $322,575, or $1,275 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.

[[Page 12258]]

    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.

    (2) If any damage is found during any inspection required in 
paragraph (g) of this AD, that affects only the insulation of 
harness W205 of the APU ESC power cables: Before further flight, 
repair the insulation and install a new grommet support having P/N 
191-21716-003 in the tail cone firewall, in accordance with the 
Accomplishment Instructions of Embraer Service Bulletin 170-53-0093,

    (3) If any damage is found during any inspection required in 
paragraph (g) of this AD that affects the insulation of harness W205 
of the APU ESC power cables and the inner conductors: Before further 
flight, replace the harness with a new harness and install a new 
grommet support having P/N 191-21716-003 in the tail cone firewall,
