Airworthiness Directives; ATR--GIE Avions de Transport Reacutegional 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 Reacutegional 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 Reacutegional 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 Reacutegional 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:
-
Is not a ``significant regulatory action'' under Executive Order 12866;
-
Is not a ``significant rule'' under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979);
-
Will not affect intrastate aviation in Alaska; and
-
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.
