ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for all Airbus Model A300 B4–603, B4–605R, and B4–622R airplanes; Model A300 C4–605R Variant F airplanes; and Model A300 F4–600R series airplanes. This AD was prompted by a report that chafing was detected between the autopilot electrical wiring conduit and the wing bottom skin. This AD requires modifying the wiring installation on the right-hand wing. We are issuing this AD to prevent sparking due to electrical chafing when flammable vapors are present in the area, which could cause an uncontrolled fire. SUMMARY: E:\FR\FM\08AUR1.SGM 08AUR1 47274 Federal Register / Vol. 77, No. 153 / Wednesday, August 8, 2012 / Rules and Regulations This AD becomes effective September 12, 2012.

SUPPLEMENTARY INFORMATION: DATES: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on March 15, 2012 (77 FR 15291). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: During a scheduled general visual inspection in a zone adjacent to a fuel tank (zone 675) chafing was detected between the autopilot electrical wiring conduit and the wing bottom skin. This condition, in the scope of published FAA SFAR88 [Special Federal Aviation Regulation] and JAA [Joint Aviation Authority] Internal Policy INT/POL/25/12, is considered on ground to be a potential source of explosive condition due to the risk of a spark with electrical wire chafing when flammable vapours are present in the area. If left uncorrected, this condition could lead to an uncontrolled fire. For the reasons described above, this [EASA] AD requires modification of the wiring installation to improve the routing and the protection of the harnesses in the zone 675/Rib 6 of the Right Hand wing. You may obtain further information by examining the MCAI in the AD docket. wreier-aviles on DSK5TPTVN1PROD with RULES Comments We gave the public the opportunity to participate in developing this AD. We considered the comment received. Request To Extend the Compliance Time UPS requested that we extend the proposed compliance time. The NPRM (77 FR 15291, March 15, 2012) proposed a compliance time of ‘‘within 30 months or 4,500 flight hours after the effective date of this AD,’’ for modifying the wiring in zone 675 of the right-hand VerDate Mar<15>2010 13:48 Aug 07, 2012 Jkt 226001 wing. UPS stated that extending the compliance time to ‘‘within 40 months or 4,500 flight hours after the effective date of this AD,’’ would allow it to accomplish the required actions at its heavy maintenance facility during Ccheck visits. UPS stated that the line maintenance environment is not conducive to this type of work due to the required ground time, labor, and other resources, which are available at its major maintenance facility. UPS stated that its current maintenance program is based on a 30-month C-check interval. UPS also stated that in order to accommodate this modification at Ccheck in its major maintenance facility, it will need an additional 10 months to allow for planning and preparations, including developing engineering orders, prototyping, obtaining necessary management and finance approvals, parts acquisition, and parts lead-time. We do not agree to extend the compliance time specified in this final rule. In developing an appropriate compliance time for this action, we considered the urgency associated with the subject unsafe condition, the manufacturer’s recommendations, the availability of required parts, and the practical aspect of accomplishing the required modification within a period of time that corresponds to the normal scheduled maintenance for most affected operators. Under the provisions of paragraph (h)(1) of the final rule, we will consider requests for approval of an extension of the compliance time if sufficient data are submitted to substantiate that the new compliance time would provide an acceptable level of safety. We have not changed the AD in this regard. Conclusion We reviewed the available data, including the comment received, and determined that air safety and the public interest require adopting the AD as proposed. Costs of Compliance We estimate that this AD will affect 132 products of U.S. registry. We also estimate that it will take about 7 workhours 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 $1,720 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 PO 00000 Frm 00008 Fmt 4700 Sfmt 4700 this AD to the U.S. operators to be $305,580, or $2,315 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. 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. We prepared a regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD docket. Examining the AD Docket You may examine the AD docket on the Internet at https:// www.regulations.gov; or in person at the Docket Operations office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains the NPRM (77 FR 15291, March 15, 2012), the regulatory evaluation, any comments received, and other information.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM was published in the Federal Register on March 15, 2012 (77 
FR 15291). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    During a scheduled general visual inspection in a zone adjacent 
to a fuel tank (zone 675) chafing was detected between the autopilot 
electrical wiring conduit and the wing bottom skin.
    This condition, in the scope of published FAA SFAR88 [Special 
Federal Aviation Regulation] and JAA [Joint Aviation Authority] 
Internal Policy INT/POL/25/12, is considered on ground to be a 
potential source of explosive condition due to the risk of a spark 
with electrical wire chafing when flammable vapours are present in 
the area. If left uncorrected, this condition could lead to an 
uncontrolled fire.
    For the reasons described above, this [EASA] AD requires 
modification of the wiring installation to improve the routing and 
the protection of the harnesses in the zone 675/Rib 6 of the Right 
Hand wing.

You may obtain further information by examining the MCAI in the AD 
docket.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the comment received.

Request To Extend the Compliance Time

    UPS requested that we extend the proposed compliance time. The NPRM 
(77 FR 15291, March 15, 2012) proposed a compliance time of ``within 30 
months or 4,500 flight hours after the effective date of this AD,'' for 
modifying the wiring in zone 675 of the right-hand wing. UPS stated 
that extending the compliance time to ``within 40 months or 4,500 
flight hours after the effective date of this AD,'' would allow it to 
accomplish the required actions at its heavy maintenance facility 
during C-check visits. UPS stated that the line maintenance environment 
is not conducive to this type of work due to the required ground time, 
labor, and other resources, which are available at its major 
maintenance facility. UPS stated that its current maintenance program 
is based on a 30-month C-check interval. UPS also stated that in order 
to accommodate this modification at C-check in its major maintenance 
facility, it will need an additional 10 months to allow for planning 
and preparations, including developing engineering orders, prototyping, 
obtaining necessary management and finance approvals, parts 
acquisition, and parts lead-time.
    We do not agree to extend the compliance time specified in this 
final rule. In developing an appropriate compliance time for this 
action, we considered the urgency associated with the subject unsafe 
condition, the manufacturer's recommendations, the availability of 
required parts, and the practical aspect of accomplishing the required 
modification within a period of time that corresponds to the normal 
scheduled maintenance for most affected operators. Under the provisions 
of paragraph (h)(1) of the final rule, we will consider requests for 
approval of an extension of the compliance time if sufficient data are 
submitted to substantiate that the new compliance time would provide an 
acceptable level of safety. We have not changed the AD in this regard.

Conclusion

    We reviewed the available data, including the comment received, and 
determined that air safety and the public interest require adopting the 
AD as proposed.

Costs of Compliance

    We estimate that this AD will affect 132 products of U.S. registry. 
We also estimate that it will take about 7 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 $1,720 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 this AD to the 
U.S. operators to be $305,580, or $2,315 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.
    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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.
