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 ATR--GIE Avions de 
Transport R[eacute]gional Model ATR42-500 airplanes, and Model ATR72-
102, -202, -212, and -212A airplanes. The NPRM published in the Federal 
Register on May 12, 2015 (80 FR 27114) (``the NPRM''). The NPRM was 
prompted by a report of chafed wires between electrical harnesses. The 
NPRM proposed to require inspections for wire discrepancies, and 
corrective actions if necessary. We are issuing this AD to detect and 
correct damaged wiring and incorrect installation of the wiring harness 
and adjacent air ducts, which could lead to wire harness chafing and 
arcing, possibly resulting in an on-board fire.
    Since the NPRM was issued, the European Aviation Safety Agency 
(EASA), which is the Technical Agent for the Member States of the 
European Union, has issued EASA Airworthiness Directive 2015-0171, 
dated August 20, 2015 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for certain ATR--GIE Avions de Transport 
R[eacute]gional Model ATR42-500 airplanes, and Model ATR72-102, -202, -
212, and -212A airplanes. The MCAI states:

    An erroneous cockpit indication has been reported on an in-
service aeroplane. Subsequent investigation identified chafed wiring 
between harnesses (2M-2S-6M) and the metallic structure of the cargo 
lining panel above the electronic rack 90VU shelf. The chafing was 
most likely the result of incorrect harness installation. In some 
cases, the bracket, which supports the harnesses, could be 
incorrectly positioned. Consequently, the wiring harnesses, and in 
certain configurations, the adjacent air duct, could be incorrectly 
routed.

[[Page 9747]]

    This condition, if not detected and corrected, could lead to 
wiring harness chafing and arcing, possibly resulting in an on-board 
fire.
    Prompted by this unsafe condition, EASA issued AD 2014-0052 
(later revised) [http://www.casa.gov.au/wcmswrs/main/lib100154/2014-0052.pdf] to require a one-time visual inspection of the affected 
area including a bracket position check and, depending on findings, 
accomplishment of applicable corrective actions.
    Since EASA AD 2014-0052R1 [http://ad.easa.europa.eu/blob/easa_ad_2014_0052_R1_superseded.pdf/AD_2014-0052R1_1] was issued, 
ATR determined that more aeroplanes are potentially affected 
(referred as Group B aeroplanes) than originally identified. It was 
also determined that some aeroplanes, originally addressed by AD 
2014-0052, are not affected due to their specific configuration. 
Taking into account these findings, ATR issued Revision 03 of 
Service Bulletin (SB) ATR42-92-0024 and SB ATR72-92-1032 to reflect 
the reidentified population of affected aeroplanes.
    For the reasons described above, this [EASA] AD retains the 
requirements of EASA AD 2014-0052R1, which is superseded, and 
requires inspection, and, depending on findings, applicable 
corrective action(s), on the adjusted range of aeroplanes.

    EASA AD 2015-0171, dated August 20, 2015, replaces EASA AD 2014-
0052R1, dated April 7, 2014, which was the referenced MCAI in the NPRM. 
The revised MCAI adds certain airplanes and removes others from the 
applicability, but does not affect any U.S.-registered airplanes. You 
may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2015-1280-0003.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM or on the determination of 
the cost to the public.

Changes to This AD

    Since the NPRM was issued, Avions de Transport R[eacute]gional has 
issued Service Bulletin ATR42-92-0024, Revision 03, dated January 21, 
2015; and Service Bulletin ATR72-92-1032, Revision 03, dated January 
21, 2015. No additional work is required for airplanes that have 
accomplished the actions specified in any previous version. We have 
revised paragraphs (g) and (h) of this AD to reference this revised 
service information. We have revised paragraph (i) of this AD to give 
credit for actions done before the effective date of this AD using the 
following service bulletins.
     Avions de Transport R[eacute]gional Service Bulletin 
ATR42-92-0024, Revision 01, dated January 16, 2014.
     Avions de Transport R[eacute]gional Service Bulletin 
ATR42-92-0024, Revision 02, dated April 17, 2014.
     Avions de Transport R[eacute]gional Service Bulletin 
ATR72-92-1032, Revision 01, dated January 16, 2014.
     Avions de Transport R[eacute]gional Service Bulletin 
ATR72-92-1032, Revision 02, dated April 17, 2014.
    We have also revised paragraph (c) of this AD to refer to the 
manufacturer serial numbers of the affected airplanes as identified in 
EASA AD 2015-0171, dated August 20, 2015.

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 for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Related Service Information Under 1 CFR Part 51

    ATR--GIE Avions de Transport R[eacute]gional has issued the 
following service bulletins.
     Avions de Transport R[eacute]gional Service Bulletin 
ATR42-92-0024, Revision 03, dated January 21, 2015. The service 
information describes procedures for inspecting the electrical harness 
routing on top of the 90VU electrical rack, and modification if 
necessary.
     Avions de Transport R[eacute]gional Service Bulletin 
ATR72-92-1032, Revision 03, dated January 21, 2015. The service 
information describes procedures for inspecting the electrical harness 
routing on top of the 90VU electrical rack, and modification if 
necessary.
    This service information is reasonably available because the 
interested parties have access to it through their normal course of 
business or by the means identified in the ADDRESSES section.

Costs of Compliance

    We estimate that this AD affects 1 airplane of U.S. registry.
    We also estimate that it would take about 1 work-hour per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85 per work-hour. Based on these figures, we estimate the cost 
of this AD on U.S. operators to be $85, or $85 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 3 work-hours and require parts costing $82, for a cost of 
$337 per product. We have no way of determining the number of aircraft 
that might need these actions.

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 that 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);
    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.
