ACTION: Final rule. AGENCY: We are superseding airworthiness directive (AD) 2000–12– 11, for certain Model A300 B4–600 and Model A300 B4–600R series airplanes. AD 2000–12–11 required repetitive inspections to detect cracks in the bolt holes inboard and outboard of rib 9 on the bottom booms of the front and rear wing spars, and repair if necessary. This new AD reduces the initial inspection compliance time and repetitive inspection interval. This AD was prompted by a fleet survey and an updated fatigue and damage tolerance analysis indicating a high risk for fatigue cracking on the front and rear spar bottom booms. We are issuing this AD to detect and correct fatigue cracks in the bolt holes of the wing spars, which could result in reduced structural integrity of a wing spar. DATES: This AD becomes effective December 2, 2013. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of December 2, 2013.

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. The NPRM published in the Federal Register on July 3, 2013 (78 FR 40069), and proposed to supersede AD 2000– 12–11, Amendment 39–11789 (65 FR 37853, June 19, 2000). The NPRM proposed to correct an unsafe condition for the specified products. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2012–0138, dated July 26, 2012 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: Full fatigue tests carried out by the manufacturer revealed crack initiation from the bolts holes at inboard and outboard of rib 9, on the front and rear spar bottom booms. Similar cracks at the same area were reported by A300–600 aeroplane operators. This condition, if not detected and corrected, could affect the structural integrity of the aeroplane. To address this unsafe condition, ´ ´ [Direction Generale de l’Aviation Civile] DGAC France issued AD 94–208–169(B)R2 (http://ad.easa.europa.eu/blob/19942082tb_ superseded.pdf/AD_F-1994-208-169R2_2) [which corresponds to FAA AD 95–07–05, Amendment 39–9187 (60 FR 17990, April 10, 1995)] to require an ultrasonic inspection of holes inboard and outboard of rib 9 on the front and rear spar bottom booms on Left Hand and Right Hand wings. Since that [DGAC] AD was issued, a fleet survey and updated Fatigue and Damage E:\FR\FM\28OCR1.SGM 28OCR1 64160 Federal Register / Vol. 78, No. 208 / Monday, October 28, 2013 / Rules and Regulations Tolerance analysis have been performed in order to substantiate the second A300–600 Extended Service Goal (ESG2) exercise. The results of these analyses have shown that the risk for these aeroplanes is higher than initially determined and that, consequently, the inspection threshold and interval must be reduced to allow timely detection of cracks and the accomplishment of an applicable corrective action [and related investigative action]. For the reasons explained above, this new [EASA] AD retains the requirements of DGAC France AD 94–208–169(B)R2, which is superseded, and requires the accomplishment instructions within the new thresholds and intervals specified in Revision 04 of Airbus Mandatory Service Bulletin (SB) A300–57–6037 [dated February 24, 2011]. corrective actions include oversizing holes and installing new fasteners, and for certain conditions, contacting the FAA or EASA (or its delegated agent) for instructions. You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/ #!documentDetail;D=FAA-2013-05390002. The related investigative action includes doing inspections for cracking. The We reviewed the available data and determined that air safety and the Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (78 FR 40069, July 3, 2013) or on the determination of the cost to the public. Conclusion public interest require adopting this AD as proposed—except for minor editorial changes and re-formatting of the estimates cost data. The estimated cost data has not been changed. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM (78 FR 40069, July 3, 2013) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (78 FR 40069, July 3, 2013). Costs of Compliance We estimate that this AD affects 29 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Action Labor cost Parts cost Cost per product Inspection [new action] .......... 18 work-hours × $85 per hour = $1,530 [per inspection cycle]. $0 $1,530 [per inspection cycle] We have received no definitive data that would enable us to provide cost estimates for the on-condition workhours specified in this AD. The oncondition parts cost estimate is $2,874. According to the manufacturer, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. wreier-aviles on DSK5TPTVN1PROD with RULES 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. VerDate Mar<15>2010 12:59 Oct 25, 2013 Jkt 232001 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.

ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for all Airbus Model A318, A319, A320, and A321 series airplanes. This AD was prompted by a determination that oxygen generators installed on a certain batch of passenger emergency oxygen container assemblies might become detached by extreme pulling of the mask tube at the end of the oxygen supply causing a high temperature oxygen generator and mask to fall down. This AD requires modifying the passenger emergency oxygen container assembly. We are issuing this AD to prevent a high temperature oxygen generator and mask from falling down and possibly resulting in an ignition source in the passenger compartment, injury to wreier-aviles on DSK5TPTVN1PROD with RULES SUMMARY: passengers, and reduced availability of supplemental oxygen. DATES: This AD becomes effective December 2, 2013. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of December 2, 2013. ADDRESSES: You may examine the AD on the Internet at http:// www.regulations.gov/ #!docketDetail;D=FAA-2013-0465; or in person at the U.S. Department of Transportation, Docket Operations, M– 30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue SE., Washington, DC.

SUPPLEMENTARY INFORMATION: It has been determined that oxygen generators, installed on a specific batch of Type 1 (22 minute) passenger emergency oxygen container assemblies, may become detached by extreme pulling of the mask tube at the end of oxygen supply. Investigations revealed that such detachment can be caused by the increase in temperature towards the end of the generator operation, which may weaken the plastic housing in the attachment area of the bracket. This condition, if not corrected, could make the rivets slip through the plastic housing, causing a ‘hot’ oxygen generator and mask to fall down, possibly resulting in injury to passengers. For the reasons described above, this [EASA] AD requires modification of the affected oxygen container assemblies. This [EASA] AD also prohibits the installation of the affected (unmodified) containers on any aeroplane as replacement parts. 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. The NPRM published in the Federal Register on July 3, 2013 (78 FR 40074). The NPRM proposed to correct an unsafe condition for the specified products. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2012–0055, dated April 3, 2012 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: We reviewed the available data and determined that air safety and the public interest require adopting this AD as proposed–except for minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM (78 FR 40074, July 3, 2013) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (78 FR 40074, July 3, 2013). The modification consists of adding a reinforcement plate at the rear outside of the container and adding two washers to the rivets at the inside of the container to prevent the generator from detaching. You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/ #!documentDetail;D=FAA-2013-04650002. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (78 FR 40074, July 3, 2013) or on the determination of the cost to the public. Conclusion Costs of Compliance We estimate that this AD affects 4 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Action Labor cost Modification ..................................................... 2 work-hours × $85 per hour = $170 .............

Airworthiness Directives; Airbus Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are superseding airworthiness directive (AD) 2000-12-11, 
for certain Model A300 B4-600 and Model A300 B4-600R series airplanes. 
AD 2000-12-11 required repetitive inspections to detect cracks in the 
bolt holes inboard and outboard of rib 9 on the bottom booms of the 
front and rear wing spars, and repair if necessary. This new AD reduces 
the initial inspection compliance time and repetitive inspection 
interval. This AD was prompted by a fleet survey and an updated fatigue 
and damage tolerance analysis indicating a high risk for fatigue 
cracking on the front and rear spar bottom booms. We are issuing this 
AD to detect and correct fatigue cracks in the bolt holes of the wing 
spars, which could result in reduced structural integrity of a wing 
spar.

DATES: This AD becomes effective December 2, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of December 2, 
2013.

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. 
The NPRM published in the Federal Register on July 3, 2013 (78 FR 
40069), and proposed to supersede AD 2000-12-11, Amendment 39-11789 (65 
FR 37853, June 19, 2000). The NPRM proposed to correct an unsafe 
condition for the specified products.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2012-0138, dated July 26, 2012 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    Full fatigue tests carried out by the manufacturer revealed 
crack initiation from the bolts holes at inboard and outboard of rib 
9, on the front and rear spar bottom booms. Similar cracks at the 
same area were reported by A300-600 aeroplane operators.
    This condition, if not detected and corrected, could affect the 
structural integrity of the aeroplane.
    To address this unsafe condition, [Direction 
G[eacute]n[eacute]rale de l'Aviation Civile] DGAC France issued AD 
94-208-169(B)R2 (http://ad.easa.europa.eu/blob/19942082tb_superseded.pdf/AD_F-1994-208-169R2_2) [which corresponds to FAA AD 
95-07-05, Amendment 39-9187 (60 FR 17990, April 10, 1995)] to 
require an ultrasonic inspection of holes inboard and outboard of 
rib 9 on the front and rear spar bottom booms on Left Hand and Right 
Hand wings.
    Since that [DGAC] AD was issued, a fleet survey and updated 
Fatigue and Damage

[[Page 64160]]

Tolerance analysis have been performed in order to substantiate the 
second A300-600 Extended Service Goal (ESG2) exercise. The results 
of these analyses have shown that the risk for these aeroplanes is 
higher than initially determined and that, consequently, the 
inspection threshold and interval must be reduced to allow timely 
detection of cracks and the accomplishment of an applicable 
corrective action [and related investigative action].
    For the reasons explained above, this new [EASA] AD retains the 
requirements of DGAC France AD 94-208-169(B)R2, which is superseded, 
and requires the accomplishment instructions within the new 
thresholds and intervals specified in Revision 04 of Airbus 
Mandatory Service Bulletin (SB) A300-57-6037 [dated February 24, 
2011].

The related investigative action includes doing inspections for 
cracking. The corrective actions include oversizing holes and 
installing new fasteners, and for certain conditions, contacting the 
FAA or EASA (or its delegated agent) for instructions. You may examine 
the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2013-0539-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (78 FR 40069, July 3, 
2013) or on the determination of the cost to the public.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting this AD as proposed--except for 
minor editorial changes and re-formatting of the estimates cost data. 
The estimated cost data has not been changed. We have determined that 
these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (78 FR 40069, July 3, 2013) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (78 FR 40069, July 3, 2013).

Costs of Compliance

    We estimate that this AD affects 29 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------

                                   cycle].
----------------------------------------------------------------------------------------------------------------

    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition work-hours specified in this AD. 
The on-condition parts cost estimate is $2,874.
    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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.
