SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to adding an AD that would ¨ apply to Ballonbau Worner GmbH Model NL–280/STU, NL–380/STU, NL– 510/STU, NL–640/STU, NL–840/STU, and NL–1000/STU airplane. The NPRM was published in the Federal Register on January 31, 2014 (79 FR 5319). The NPRM proposed to correct an unsafe condition for the specified products and was based on mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country. The MCAI states: The results of an analysis of NL–STU maintenance data revealed that the current inspection intervals are no longer adequate to ensure timely detection of deterioration or damage, which could affected the structural integrity of the balloon. This condition, if not detected and corrected, could lead to failure of balloon components or envelope, possibly resulting in loss of the balloon. To address this potential unsafe condition, ¨ Ballonbau Worner developed new, more detailed and descriptive Instructions for Continued Airworthiness (at the same time separated from the Flight Manual) and issued Technische Mitteilung/Technical Note EASA.BA.009–6 to inform all operators. For the reasons described above, EASA issued AD 2013–0293 to require compliance PO 00000 Frm 00006 Fmt 4700 Sfmt 4700 with the updated Instructions for Continued Airworthiness. This AD is revised to extend the compliance time for the initial porosity test, for balloons which have already exceeded the relevant threshold. The MCAI can be found in the AD docket on the Internet at: http:// www.regulations.gov/ #!documentDetail;D=FAA-2014-00410002. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (79 FR 5319, January 31, 2014) or on the determination of the cost to the public. Conclusion We reviewed the relevant data and determined that air safety and the public interest require adopting the 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 (79 FR 5319, January 31, 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 5319, January 31, 2014). Costs of Compliance We estimate that this AD will affect 6 products of U.S. registry. The scope of the inspections may vary depending on the condition of the balloon. We have no way of knowing how extensive an inspection may be necessary for each balloon. The scope of damage found in the inspections could vary significantly from balloon to balloon. We have no way of determining how much damage may be found on each balloon or the cost to repair damaged parts on each balloon or the number of balloons that may require 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 E:\FR\FM\22APR1.SGM 22APR1 Federal Register / Vol. 79, No. 77 / Tuesday, April 22, 2014 / Rules and Regulations 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 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.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2012–03–04, Amendment 39–16945 (77 FR 21397, April 10, 2012). AD 2012–03–04 applied to certain Airbus Model A310 series airplanes. The NPRM published in the Federal Register on January 14, 2014 (79 FR 2391). The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2012–0188, dated September 19, 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: Within the scope of the Fuel System Safety Program (FSSP), analyses of the wire routing showed that the route 2S of the fuel electrical circuit in the Right Hand (RH) wing ensures insufficient segregation between fuel quantity indication wires and the 115 Volts Alternating Current (VAC) wires of route 2S which could, under certain conditions, lead to a short circuit and subsequent arcing, creating a potential ignition source in the fuel tank vapour space. This condition, if not detected, could result in a fuel tank explosion and consequent loss of the aeroplane. To address this potential unsafe condition, DGAC France issued [an] AD *** to require improvements of the design as specified in Airbus Service Bulletin (SB) A310–28–2148 PO 00000 Frm 00008 Fmt 4700 Sfmt 4700 original issue or Revision 01. EASA AD 2007–0230 [(http://ad.easa.europa.eu/blob/ easa_ad_2007_0230_Superseded.pdf/AD_ 2007-0230_1)], which superseded [a] DGAC France AD ***, [which] required those same actions, plus additional work 1, as defined in Airbus SB A310–28–2148 Revision 02. Since EASA AD 2007–0230 was issued, an operator reported the possibility of chafing between the new routing of the wire bundle 2S in the RH wing pylon area and the wire bundle of No.2 engine generator. The modification of this zone was introduced by Airbus SB A310–28–2148 Revision 02 as additional work 1. Investigation results showed that, to avoid the risk of chafing, the affected wiring harnesses must be installed at a higher position to provide sufficient clearance with the newly routed wire bundle 2S conduit. Airbus published Revision 03 of SB A310– 28–2148 to implement these changes as additional work 2. Subsequently, a new potential interference due to insufficient clearance was found, which prompted Airbus to issue SB A310–28–2148 Revision 04. Prompted by these findings and actions, EASA issued AD 2011–0005 [(http:// ad.easa.europa.eu/blob/easa_ad_2011_0005_ Superseded.pdf/AD_2011-0005_1)], retaining the requirements of EASA AD 2007–0230, which was superseded, and required the additional work 2 as specified in Revisions 03 and 04 of Airbus SB A310–28–2148. Since EASA AD 2011–0005 was issued, several operators of aeroplanes not having been modified in-service through Airbus SB A310–36–2015, or without having Airbus modification 07633 applied in production, reported to have embodied Airbus SB A310– 28–2148 at Revision 02 or Revision 03 on the aeroplane. However, the adequate instructions to avoid the new interferences were only introduced in Airbus SB A310–28– 2148 Revision 04. For the reasons described above, this new [EASA] AD retains the requirements of EASA AD 2011–0005, which is superseded, and requires, for certain aeroplanes, the additional work 3 [segregating wire route 2S in the RH pylon area or modifying the wire routings] as defined in Airbus SB A310–28– 2148 Revision 06. As SB A310–28–2148 Revision 07 was issued to clarify the additional work 1, 2 and 3 [segregating wire route 2S in the RH pylon area or modifying the wire routings] for aeroplanes that have previously embodied that SB at original issue, Revision 01 or Revision 02, this AD also clarifies the required additional work. You may examine the MCAI in the AD docket on the Internet at http:// www.regulations.gov/ #!documentDetail;D=FAA-2013-10720002. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (79 FR 2391, January 14, 2014) or on the determination of the cost to the public.

Airworthiness Directives; Ballonbau W[ouml]rner GmbH Balloons

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for 
Ballonbau W[ouml]rner GmbH Models NL-280/STU, NL-380/STU, NL-510/STU, 
NL-640/STU, NL-840/STU, and NL-1000/STU balloons. This AD results from 
mandatory continuing airworthiness information (MCAI) issued by an 
aviation authority of another country to identify and correct an unsafe 
condition on an aviation product. The MCAI describes the unsafe 
condition as current inspection intervals are no longer adequate to 
ensure timely detection of deterioration or damage. We are issuing this 
AD to require actions to address the unsafe condition on these 
products.

DATES: This AD is effective May 27, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of May 27, 2014.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to adding an AD that would apply to Ballonbau W[ouml]rner GmbH 
Model NL-280/STU, NL-380/STU, NL-510/STU, NL-640/STU, NL-840/STU, and 
NL-1000/STU airplane. The NPRM was published in the Federal Register on 
January 31, 2014 (79 FR 5319). The NPRM proposed to correct an unsafe 
condition for the specified products and was based on mandatory 
continuing airworthiness information (MCAI) originated by an aviation 
authority of another country. The MCAI states:

    The results of an analysis of NL-STU maintenance data revealed 
that the current inspection intervals are no longer adequate to 
ensure timely detection of deterioration or damage, which could 
affected the structural integrity of the balloon.
    This condition, if not detected and corrected, could lead to 
failure of balloon components or envelope, possibly resulting in 
loss of the balloon.
    To address this potential unsafe condition, Ballonbau 
W[ouml]rner developed new, more detailed and descriptive 
Instructions for Continued Airworthiness (at the same time separated 
from the Flight Manual) and issued Technische Mitteilung/Technical 
Note EASA.BA.009-6 to inform all operators.
    For the reasons described above, EASA issued AD 2013-0293 to 
require compliance with the updated Instructions for Continued 
Airworthiness. This AD is revised to extend the compliance time for 
the initial porosity test, for balloons which have already exceeded 
the relevant threshold.

    The MCAI can be found in the AD docket on the Internet at: http://www.regulations.gov/#!documentDetail;D=FAA-2014-0041-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (79 FR 5319, January 31, 
2014) or on the determination of the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting the 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 (79 FR 5319, January 31, 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 5319, January 31, 2014).

Costs of Compliance

    We estimate that this AD will affect 6 products of U.S. registry. 
The scope of the inspections may vary depending on the condition of the 
balloon. We have no way of knowing how extensive an inspection may be 
necessary for each balloon. The scope of damage found in the 
inspections could vary significantly from balloon to balloon. We have 
no way of determining how much damage may be found on each balloon or 
the cost to repair damaged parts on each balloon or the number of 
balloons that may require 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

[[Page 22363]]

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 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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

     Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new AD:

2014-07-10 Ballonbau W[ouml]orner GmbH: Amendment 39-17824; Docket 
No. FAA-2014-0041; Directorate Identifier 2013-CE-053-AD.

(a) Effective Date

    This airworthiness directive (AD) becomes effective May 27, 
2014.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Ballonbau W[ouml]rner GmbH Model NL-280/STU, 
NL-380/STU, NL-510/STU, NL-640/STU, NL-840/STU, and NL-1000/STU 
balloons, all serial numbers, certificated in any category.

(d) Subject

    Air Transport Association of America (ATA) Code 5: Time Limits/
Maintenance Checks.

(e) Reason

    This AD was prompted by mandatory continuing airworthiness 
information (MCAI) originated by an aviation authority of another 
country to identify and correct an unsafe condition on an aviation 
product. The MCAI describes the unsafe condition as current 
inspection intervals are no longer adequate to ensure timely 
detection of deterioration or damage. If this condition is 
uncorrected, it could result in reduced structural integrity of the 
balloon.

(f) Actions and Compliance

    Unless already done, do the actions in paragraphs (f)(1) through 
(f)(4) of this AD:
    (1) Before further flight after May 27, 2014 (the effective date 
of this AD), complete all inspections and maintenance tasks 
described in the Chapter 5, Annual Inspection, in the Ballonbau 
W[ouml]rner GmbH Instructions for Continued Airworthiness, Gas 
Balloon Model NL-STU, Issue 1, pages 44 through 53 and 55 through 
69, dated November 2013, and page 54 dated December 2013.
    (2) If any discrepancies are found during the inspection 
required in paragraph (f)(1) of this AD, before further flight, 
repair as applicable following Chapter 6, Standard Repair 
Procedures, in the Ballonbau W[ouml]rner GmbH Instructions for 
Continued Airworthiness, Gas Balloon Model NL-STU, Issue 1, dated 
November 2013.
    (3) If on May 27, 2014 (the effective date of this AD), a 
balloon has already exceeded the threshold compliance time for the 
porosity test as defined in Sections 5.1.1.4, 5.1.2.4 and 5.1.3.4 of
