We propose to adopt a new airworthiness directive (AD) for certain ATR-GIE Avions de Transport R[eacute]gional Model ATR42-500 airplanes, and Model ATR72-102, -202, -212, and -212A airplanes. This proposed AD was prompted by a report of chafed wires between electrical harnesses. This proposed AD would require inspections for wiring discrepancies, and corrective actions if necessary. We are proposing 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.

Airworthiness Directives; ATR-GIE Avions de Transport 
R[eacute]gional 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 ATR-GIE Avions de Transport R[eacute]gional Model ATR42-500 
airplanes, and Model ATR72-102, -202, -212, and -212A airplanes. This 
proposed AD was prompted by a report of chafed wires between electrical 
harnesses. This proposed AD would require inspections for wiring 
discrepancies, and corrective actions if necessary. We are proposing 
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.

DATES: We must receive comments on this proposed AD by June 26, 2015.

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 European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2014-0052R1, dated April 7, 2014 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for certain ATR-

[[Page 27115]]

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 aircraft. 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.
    This condition, if not detected and corrected, could lead to 
wiring harness chafing and arcing, possibly resulting in an on-board 
fire.
    To address this potential unsafe condition, ATR issued Service 
Bulletin (SB) ATR42-92-0024 and SB ATR72-92-1032, as applicable to 
aeroplane model, to provide inspection instructions.
    For the reasons described above, EASA issued AD 2014-0052 
[http://www.casa.gov.au/wcmswr/_assets/main/lib100154/2014-0052.pdf] 
to require a one-time visual inspection of the affected area 
including a systematic bracket position check and, depending on 
findings, accomplishment of applicable corrective actions.
    This [EASA] AD is revised to make the bracket position check 
dependent on findings, determined during the inspection of the 
electrical bundle and air duct routing. Corrective actions include 
repairing damaged wiring, correctly installing the bracket which 
supports bundle 2M-2S-6M, and routing bundle 2M-2S-6M and the air 
conditioning flexible hose in the correct positions.

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-2015-
1280.

Related Service Information Under 1 CFR Part 51

    ATR-GIE Avions de Transport R[eacute]gional has issued Service 
Bulletin ATR42-92-0024, Revision 01, dated January 16, 2014. The 
service information describes procedures for inspecting the electrical 
harness routing on the top of 90VU electric rack and to modify it if 
necessary.
    ATR-GIE Avions de Transport R[eacute]gional has also issued Service 
Bulletin ATR72-92-1032, Revision 01, dated January 16, 2014. The 
service information describes procedures for inspecting the electrical 
harness routing on the top of 90VU electric rack and to modify it if 
necessary.
    The actions described in this service information are intended to 
correct the unsafe condition identified in the MCAI. 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 of this NPRM.

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 these 
same type designs.

Costs of Compliance

    We estimate that this proposed 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 proposed AD. The average 
labor rate is $85 per work-hour. Based on these figures, we estimate 
the cost of this proposed 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 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.
