ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for certain Airbus Model A300 B4–600 and A300 B4–600R series airplanes. This AD was prompted by reports of cracks found in certain bottom wing skin stringers during full-scale fatigue testing and in service. This AD requires modifying the profile of stringer run-outs of both wings, including a high frequency eddy current inspection of the fastener holes for defects and, if necessary, repairs. We are issuing this AD to prevent cracking in the bottom wing skin stringers, which could result in reduced structural integrity of the wings. DATES: This AD becomes effective May 21, 2014. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of May 21, 2014.

SUPPLEMENTARY INFORMATION: necessary, repairs. You may examine the MCAI in the AD docket on the Internet at https://www.regulations.gov/ #!documentDetail;D=FAA-2013-06680002. Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Airbus Model A300 B4– 600 and A300 B4–600R series airplanes. The NPRM published in the Federal Register on August 1, 2013 (78 FR 46536). The NPRM was prompted by reports of cracks found in the bottom wing skin stringers at rib 14 during fullscale fatigue testing and in service. The NPRM proposed to require modifying the profile of stringer run-outs at rib 14 of both wings, including a high frequency eddy current inspection of the fastener holes for defects and repairs if necessary. We are issuing this AD to prevent cracking in the bottom wing skin stringers, which could result in reduced structural integrity of the wings. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2013–0008R1, dated January 22, 2013 (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: Request To Refer to New Service Information During full-scale fatigue testing, cracks were detected in the bottom wing skin stringers at rib 14. In addition, A300 aeroplane operators have also reported finding cracks in the same area. This condition, if not detected and corrected, could impair the structural integrity of the wings. Additional analysis results showed that the improved design of the stringer run-out is necessary for aeroplanes operating beyond the ESG 1 [extended service goal 1: 42,500 flight cycles]. For the reasons described above, this [EASA] AD requires the removal of the stringer end run-out plate at stringer 19 on the bottom wing skin and the re-profiling modification of the stringers 10, 11, 12, 17 and 19. * * * * * The modification also includes doing a high frequency eddy current inspection of the fastener holes for defects and, if PO 00000 Frm 00008 Fmt 4700 Sfmt 4700 Comments We gave the public the opportunity to participate in developing this AD. The following presents the comment received on the NPRM (78 FR 46536, August 1, 2013) and the FAA’s response to the comment. UPS requested that the source of work instructions for accomplishing the proposed actions be revised to Airbus Mandatory Service Bulletin A300–57– 6046, Revision 02, dated June 21, 2013. UPS noted that the NPRM (78 FR 46536, August 1, 2013) referenced Airbus Mandatory Service Bulletin A300–57– 6046, Revision 01, dated April 18, 2011, as the source of work instructions. We agree. We have revised paragraph (g) of this final rule to refer to Airbus Mandatory Service Bulletin A300–57– 6046, Revision 02, dated June 21, 2013, instead. We have revised paragraph (i) of this AD to also identify Airbus Mandatory Service Bulletin A300–57– 6046, Revision 01, dated April 18, 2011, as an acceptable source of instructions if those actions are accomplished before the effective date of this AD. Additional Change We have revised paragraph (g) of this final rule to clarify when the applicable repairs are required to be done. Conclusion We reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting this AD with the changes described previously and minor editorial changes. We have determined that these changes: • Are consistent with the intent that was proposed in the NPRM (78 FR 46536, August 1, 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 46536, August 1, 2013). We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD. 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: E:\FR\FM\16APR1.SGM 16APR1 Federal Register / Vol. 79, No. 73 / Wednesday, April 16, 2014 / Rules and Regulations 21393 ESTIMATED COSTS Action Labor cost Parts cost Cost per product Cost on U.S. operators Modification of the profile of stringer run-outs. 60 work-hours × $85 per hour = $5,100.

We have no way of determining the number of aircraft that might need this repair. 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. pmangrum on DSK3VPTVN1PROD with RULES Regulatory Findings Examining the AD Docket You may examine the MCAI in the AD docket on the Internet at https:// 14:43 Apr 15, 2014 List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

ACTION: Final rule. AGENCY: This rule amends the Export Administration Regulations (EAR) by adding one person under two entries to the Entity List. The person who is added to the Entity List has been determined by the U.S. Government to be acting contrary to the national security or foreign policy interests of the United States. This person will be listed on the Entity List under the destination of Crimea (Occupied) with a cross reference added under Ukraine. DATES: Effective Date: This rule is effective April 16, 2014.

SUPPLEMENTARY INFORMATION: SUMMARY: Background The Entity List (Supplement No. 4 to Part 744) notifies the public about entities that have engaged in activities that could result in an increased risk of the diversion of exported, reexported or transferred (in-country) items to weapons of mass destruction (WMD) programs. Since its initial publication, grounds for inclusion on the Entity List have expanded to include activities sanctioned by the State Department and activities contrary to U.S. national security or foreign policy interests, including terrorism and export control violations involving abuse of human rights. Certain exports, reexports, and transfers (in-country) to entities identified on the Entity List require licenses from BIS and are usually subject to a policy of denial. The availability of license exceptions in such transactions is very limited. The license review policy for each entity is identified in the license review policy column on the Entity List and the availability of license exceptions is noted in the Federal Register notices adding persons to the Entity List. BIS places entities on the Entity List based PO 00000 Frm 00010 Fmt 4700 Sfmt 4700 on certain sections of part 744 (Control Policy: End-User and End-Use Based) of the EAR. The End-User Review Committee (ERC), composed of representatives of the Departments of Commerce (Chair), State, Defense, Energy and, where appropriate, the Treasury, makes all decisions regarding additions to, removals from, or other modifications to the Entity List. The ERC makes all decisions to add an entry to the Entity List by majority vote and all decisions to remove or modify an entry by unanimous vote. The Departments represented on the ERC approved these changes to the Entity List. ERC Entity List Decisions Addition to the Entity List This rule implements the decision of the ERC to add one person under two entries to the Entity List on the basis of § 744.11 (License requirements that apply to entities acting contrary to the national security or foreign policy interests of the United States) of the EAR. The two entries added to the Entity List consist of one entry in Crimea (Occupied) with an additional entry added to provide a cross reference from Ukraine. The ERC’s decision to add ‘Crimea (Occupied)’ to the Country column of the Entity List results from the U.S. government’s decision to use ‘Crimea (Occupied)’ to describe the purported annexation of Crimea by the Russian Federation. The ERC reviewed § 744.11(b) (Criteria for revising the Entity List) in making the determination to add this one person under two entities to the Entity List. Under that paragraph, persons for whom there is reasonable cause to believe, based on specific and articulable facts, have been involved, are involved, or pose a significant risk of being or becoming involved in, activities that are contrary to the national security or foreign policy interests of the United States and those acting on behalf of such persons may be added to the Entity List. The one person under two entries being added to the entity list is a regional oil and gas company in Crimea, Chernomorneftegaz, a.k.a. Chornomornaftogaz and NJSC Chornomornaftogaz, which is a subsidiary of Naftogaz. Chernomorneftegaz, a.k.a. Chornomornaftogaz and NJSC Chornomornaftogaz, has been determined by the ERC to be involved in activities that are contrary to the national security or foreign policy interests of the United States. The U.S. Government has determined that the E:\FR\FM\16APR1.SGM 16APR1

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Airbus Model A300 B4-600 and A300 B4-600R series airplanes. This AD was 
prompted by reports of cracks found in certain bottom wing skin 
stringers during full-scale fatigue testing and in service. This AD 
requires modifying the profile of stringer run-outs of both wings, 
including a high frequency eddy current inspection of the fastener 
holes for defects and, if necessary, repairs. We are issuing this AD to 
prevent cracking in the bottom wing skin stringers, which could result 
in reduced structural integrity of the wings.

DATES: This AD becomes effective May 21, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of May 21, 
2014.

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 Airbus Model A300 
B4-600 and A300 B4-600R series airplanes. The NPRM published in the 
Federal Register on August 1, 2013 (78 FR 46536). The NPRM was prompted 
by reports of cracks found in the bottom wing skin stringers at rib 14 
during full-scale fatigue testing and in service. The NPRM proposed to 
require modifying the profile of stringer run-outs at rib 14 of both 
wings, including a high frequency eddy current inspection of the 
fastener holes for defects and repairs if necessary. We are issuing 
this AD to prevent cracking in the bottom wing skin stringers, which 
could result in reduced structural integrity of the wings.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2013-0008R1, dated January 22, 2013 (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:

    During full-scale fatigue testing, cracks were detected in the 
bottom wing skin stringers at rib 14. In addition, A300 aeroplane 
operators have also reported finding cracks in the same area.
    This condition, if not detected and corrected, could impair the 
structural integrity of the wings.
    Additional analysis results showed that the improved design of 
the stringer run-out is necessary for aeroplanes operating beyond 
the ESG 1 [extended service goal 1: 42,500 flight cycles].
    For the reasons described above, this [EASA] AD requires the 
removal of the stringer end run-out plate at stringer 19 on the 
bottom wing skin and the re-profiling modification of the stringers 
10, 11, 12, 17 and 19.
* * * * *
The modification also includes doing a high frequency eddy current 
inspection of the fastener holes for defects and, if necessary, 
repairs. You may examine the MCAI in the AD docket on the Internet at 
https://www.regulations.gov/#!documentDetail;D=FAA-2013-0668-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comment received on the NPRM (78 FR 
46536, August 1, 2013) and the FAA's response to the comment.

Request To Refer to New Service Information

    UPS requested that the source of work instructions for 
accomplishing the proposed actions be revised to Airbus Mandatory 
Service Bulletin A300-57-6046, Revision 02, dated June 21, 2013. UPS 
noted that the NPRM (78 FR 46536, August 1, 2013) referenced Airbus 
Mandatory Service Bulletin A300-57-6046, Revision 01, dated April 18, 
2011, as the source of work instructions.
    We agree. We have revised paragraph (g) of this final rule to refer 
to Airbus Mandatory Service Bulletin A300-57-6046, Revision 02, dated 
June 21, 2013, instead. We have revised paragraph (i) of this AD to 
also identify Airbus Mandatory Service Bulletin A300-57-6046, Revision 
01, dated April 18, 2011, as an acceptable source of instructions if 
those actions are accomplished before the effective date of this AD.

Additional Change

    We have revised paragraph (g) of this final rule to clarify when 
the applicable repairs are required to be done.

Conclusion

    We reviewed the relevant data, considered the comment received, and 
determined that air safety and the public interest require adopting 
this AD with the changes described previously and minor editorial 
changes. We have determined that these changes:
     Are consistent with the intent that was proposed in the 
NPRM (78 FR 46536, August 1, 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 46536, August 1, 2013).
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

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:

    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.

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2014-08-02 Airbus: Amendment 39-17826. Docket No. FAA-2013-0668; 
Directorate Identifier 2013-NM-017-AD.

(a) Effective Date

    This AD becomes effective May 21, 2014.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Airbus Model A300 B4-601, B4-603, B4-620, and 
B4-622 airplanes; and Airbus Model A300 B4-605R and B4-622R 
airplanes; certificated in any category, except airplanes on which 
Airbus Modification 10324 or 10325 has been embodied in production.

(d) Subject

    Air Transport Association (ATA) of America Code 57, Wings.

(e) Reason

    This AD was prompted by reports of cracks found in the bottom 
wing skin stringers at rib 14 during full-scale fatigue testing and 
in service. We are issuing this AD to prevent cracking in the bottom 
wing skin stringers, which could result in reduced structural 
integrity of the wings.

(f) Compliance

    You are responsible for having the actions required by this AD 
performed within the compliance times specified, unless the actions 
have already been done.

(g) Modification of Rib 14

    Before the accumulation of 42,500 total flight cycles, or within 
2,000 flight cycles after the effective date of this AD, whichever 
occurs later, modify the profile of stringer run-outs at rib 14 of 
both wings, including a high frequency eddy current inspection of 
the fastener holes for defects and all applicable repairs, in 
accordance with the Accomplishment Instructions of Airbus Mandatory 
Service Bulletin A300-57-6046, Revision 02, dated June 21, 2013, 
except as required by paragraph (h) of this AD. Do all applicable 
repairs before further flight.

(h) Exception to the Service Information

    Where Airbus Mandatory Service Bulletin A300-57-6046, Revision 
02, dated June 21, 2013, specifies to contact Airbus for repair 
instructions, this AD requires contacting the Manager, ANM-116, 
International Branch, Transport Airplane Directorate, FAA, or the 
European Aviation Safety Agency (EASA) (or its delegated agent) for 
repair instructions and doing those repairs before further flight.

(i) Credit for Previous Actions

    This paragraph provides credit for actions required by paragraph 
(g) of this AD, if those actions were performed before the effective 
date of this AD using Airbus Service Bulletin A300-57-6046, dated 
January 18, 1994; or Airbus Mandatory Service Bulletin A300-57-6046,
