Airworthiness Directives; ATR--GIE Avions de Transport 
R[eacute]gional Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
ATR--GIE Avions de Transport R[eacute]gional Model ATR42-500 airplanes, 
and Model ATR72-212A airplanes. This AD was prompted by a report that, 
during an inspection of an airplane on the production line, 
interference was detected between the electrical harness and a bonding 
lead due to an incorrect installation of the affected bonding lead. 
This AD requires a detailed inspection for damage or incorrect routing 
of the bonding lead routing above the 120VU shelf, and if any damage or 
incorrect routing is found, repairing damage or modifying the bonding 
lead routing. We are issuing this AD to detect and correct installation 
of the bonding lead, which could cause arcing and chafing, and could 
possibly result in an uncontrolled fire.

DATES: This AD becomes effective February 25, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of February 25, 
2015.

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-
212A airplanes. The NPRM published in the Federal Register on August 
13, 2014 (79 FR 47390).
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued 
Airworthiness Directive 2014-0056, dated March 7, 2014 (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 ATR72-212A airplanes. The MCAI states:

    During inspection of an aeroplane on the production line, 
interference was detected between electrical harnesses (2M-2S-6M) 
and a bonding lead, located in zone 214, positioned above and 
forward of the 120VU shelf. Subsequent investigation revealed that 
the interference was a result of an incorrect installation of the 
affected bonding lead.
    This condition, if not detected and corrected, could lead to 
arcing and chafing, possibly resulting in an uncontrolled fire.
    To address this potential unsafe condition, ATR issued Service 
Bulletin (SB) ATR42-92-0025 and SB ATR72-92-1034, as applicable to 
aeroplane model, to provide inspection instructions.
    For the reasons described above, this [EASA] AD requires a one-
time [detailed] inspection [for damage or incorrect routing of the 
bonding lead routing above the 120VU shelf] of the electrical 
harness 2M-2S-6M in zone 214 and, depending on findings, 
accomplishment of corrective action(s) [repairing damage or 
modifying the bonding lead routing].

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2014-0530-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (79

[[Page 2818]]

FR 47390, August 13, 2014) or on the determination of the cost to the 
public.

Clarification of Corrective Actions

    In paragraph (h) of the NPRM (79 FR 47390, August 13, 2014), we 
specify modifying the bonding lead routing if any damage or incorrect 
routing is found and we refer to ATR Service Bulletin ATR42-92-0025, 
dated November 7, 2013; and ATR Service Bulletin ATR72-92-1034, dated 
November 7, 2013; as the appropriate sources of service information. 
However, ATR Service Bulletin ATR42-92-0025, dated November 7, 2013; 
and ATR Service Bulletin ATR72-92-1034, dated November 7, 2013, only 
provide corrective action if incorrect routing is found. Therefore, 
operators would have to contact the FAA for corrective action if any 
damage is found.
    We have re-designated paragraph (h) of the NPRM (79 FR 47390, 
August 13, 2014) as paragraph (h)(1) of this AD. In paragraph (h)(1) of 
this AD, we specify modifying the bonding lead routing if any incorrect 
routing is found, in accordance with ATR Service Bulletin ATR42-92-
0025, dated November 7, 2013; or ATR Service Bulletin ATR72-92-1034, 
dated November 7, 2013. We have also added paragraph (h)(2) to this AD 
to specify doing a repair if any damage is found, in accordance with a 
method approved by the Manager, International Branch, ANM-116, 
Transport Airplane Directorate, FAA.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this AD with the change described 
previously and except for minor editorial changes. We have determined 
that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (79 FR 47390, August 13, 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 47390, August 13, 2014).

Costs of Compliance

    We estimate that this AD affects 5 airplanes of U.S. registry.
    We also estimate that it will take about 2 work-hours per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85 per work-hour. Required parts will cost about $0 per 
product. Based on these figures, we estimate the cost of this AD on 
U.S. operators to be $850, or $170 per product.
    In addition, we estimate that any necessary follow-on actions will 
take about 2 work-hours and require parts costing $0, for a cost of 
$170 per product. We have no way of determining the number of aircraft 
that might need this action.

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.
