ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to supersede airworthiness directive (AD) 2007–06– 12, that applies to certain Airbus Model A330–200 and A330–300 airplanes. AD 2007–06–12 requires, for certain airplanes, reinforcement of the structure of the center fuselage by installing external stiffeners (butt straps) at frame (FR) 53.3 on the fuselage skin between left-hand (LH) and right-hand (RH) stringer (STR) 13, and related investigative and corrective actions. Since we issued AD 2007–06–12, we have determined that the compliance times must be reduced in order to address the unsafe condition. This proposed AD would reduce the compliance times for reinforcing the structure of the center fuselage at FR 53.3. We are proposing this AD to prevent fatigue cracking of the fuselage, which could result in reduced structural integrity of the fuselage. DATES: We must receive comments on this proposed AD by April 14, 2014.

We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion On March 7, 2007, we issued AD 2007–06–12, Amendment 39–14993 (72 FR 12555, March 16, 2007) (‘‘AD 2007– 06–12’’). AD 2007–06–12 requires actions intended to address an unsafe condition on the products listed above. Since we issued AD 2007–06–12, Amendment 39–14993 (72 FR 12555, March 16, 2007), we have determined that the compliance times must be reduced in order to address the unsafe condition. We have also added the E:\FR\FM\27FEP1.SGM 27FEP1 Federal Register / Vol. 79, No. 39 / Thursday, February 27, 2014 / Proposed Rules compliance time for short- and longrange airplane utilization based on the new fatigue and damage tolerance evaluation. 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– 0016, dated January 16, 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 the fatigue tests (EF2) of the Airbus A330 test fuselage, initiation and development of cracks were evidenced at the circumferential joint of frame 53.3. This condition, if not corrected, could lead to a reduction in the structural integrity of the fuselage. EASA issued AD 2006–0266 [(https:// ad.easa.europa.eu/blob/easa_ad_2006_0266_ Superseded.pdf/AD_2006–0266_1), which corresponds to FAA AD 2007–06–12, Amendment 39–14993 (72 FR 12555, March 16, 2007)], which took over the requirements ´ ´ of Direction Generale de L’aviation Civile [DGAC] France AD F–2003–415 for A330– 300 pre-mod 41652S11819, and required reinforcement of the circumferential joint of frame 53.3 by application of Airbus Service Bulletin (SB) A330–53–3143 on A330–300 post modification 41652S11819 and pre-mod 49202, and all A330–200 pre-mod 49202 in order to improve the fatigue life. Since that [EASA] AD was issued, in the frame of a new fatigue and damage tolerance evaluation taking into account the aeroplane utilisation, the thresholds for the reinforcement were reassessed and the conclusion is that some thresholds must be reduced. For the reason described above, this [EASA] AD retains the requirements of EASA AD 2006–0266, which is superseded, and requires reinforcement of structure of the centre fuselage at the upper circumferential joint of frame 53.3 within the new thresholds. The initial compliance times range between 15,700 total flight cycles or 94,600 total flight hours, whichever occurs first; and 25,600 total flight cycles or 77,000 total flight hours, whichever occurs first; depending on airplane configuration. You may examine the MCAI in the AD docket on the Internet at https:// www.regulations.gov by searching for and locating it in Docket No. FAA– 2014–0061. Relevant Service Information Airbus has issued Mandatory Service Bulletin A330–53–3127 Revision 02, including Appendix 01, dated December 7, 2011, and Mandatory Service Bulletin A330–53–3143 Revision 05, including Appendix 01, dated May 29, 2012. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. FAA’s Determination and Requirements of This Proposed AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design. Repair Approvals In many FAA transport ADs, when the service information specifies to contact the manufacturer for further instructions if certain discrepancies are found, we typically include in the AD a requirement to accomplish the action using a method approved by either the FAA or the State of Design Authority (or its delegated agent). We have recently been notified that certain laws in other countries do not 11017 allow such delegation of authority, but some countries do recognize design approval organizations. In addition, we have become aware that some U.S. operators have used repair instructions that were previously approved by a State of Design Authority or a Design Approval Holder (DAH) as a method of compliance with this provision in FAA ADs. Frequently, in these cases, the previously approved repair instructions come from the airplane structural repair manual or the DAH repair approval statements that were not specifically developed to address the unsafe condition corrected by the AD. Using repair instructions that were not specifically approved for a particular AD creates the potential for doing repairs that were not developed to address the unsafe condition identified by the MCAI AD, the FAA AD, or the applicable service information, which could result in the unsafe condition not being fully corrected. To prevent the use of repairs that were not specifically developed to correct the unsafe condition, certain requirements of this proposed AD would require that the repair approval specifically refer to the FAA AD. This change is intended to clarify the method of compliance and to provide operators with better visibility of repairs that are specifically developed and approved to correct the unsafe condition. In addition, we use the phrase ‘‘its delegated agent, or the DAH with State of Design Authority design organization approval, as applicable’’ in this proposed AD to refer to a DAH authorized to approve certain required repairs for this proposed AD. Costs of Compliance We estimate that this proposed AD affects 9 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD. ESTIMATED COSTS Action Labor cost Parts cost Cost per product Installation ..................... Up to 327 work-hour × $85 per hour = $27,795 $17,850 Up to $45,645 .............. TKELLEY on DSK3SPTVN1PROD with PROPOSALS 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. VerDate Mar<15>2010 17:29 Feb 26, 2014 Jkt 232001 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 PO 00000 Frm 00019 Fmt 4702 Sfmt 4702 Cost on U.S. operators Up to $410,805. 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 proposed AD would not have federalism implications under Executive Order 13132. This E:\FR\FM\27FEP1.SGM 27FEP1 11018 Federal Register / Vol. 79, No. 39 / Thursday, February 27, 2014 / Proposed Rules proposed AD would 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 proposed regulation: 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. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by removing airworthiness directive (AD) 2007–06–12, Amendment 39–14993 (72 FR 12555, March 16, 2007), and adding the following new AD: ■ Airbus: Docket No. FAA–2014–0061; Directorate Identifier 2013–NM–029–AD.

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede airworthiness directive (AD) 2007-06-
12, that applies to certain Airbus Model A330-200 and A330-300 
airplanes. AD 2007-06-12 requires, for certain airplanes, reinforcement 
of the structure of the center fuselage by installing external 
stiffeners (butt straps) at frame (FR) 53.3 on the fuselage skin 
between left-hand (LH) and right-hand (RH) stringer (STR) 13, and 
related investigative and corrective actions. Since we issued AD 2007-
06-12, we have determined that the compliance times must be reduced in 
order to address the unsafe condition. This proposed AD would reduce 
the compliance times for reinforcing the structure of the center 
fuselage at FR 53.3. We are proposing this AD to prevent fatigue 
cracking of the fuselage, which could result in reduced structural 
integrity of the fuselage.

DATES: We must receive comments on this proposed AD by April 14, 2014.

Discussion

    On March 7, 2007, we issued AD 2007-06-12, Amendment 39-14993 (72 
FR 12555, March 16, 2007) (``AD 2007-06-12''). AD 2007-06-12 requires 
actions intended to address an unsafe condition on the products listed 
above.
    Since we issued AD 2007-06-12, Amendment 39-14993 (72 FR 12555, 
March 16, 2007), we have determined that the compliance times must be 
reduced in order to address the unsafe condition. We have also added 
the

[[Page 11017]]

compliance time for short- and long-range airplane utilization based on 
the new fatigue and damage tolerance evaluation. The European Aviation 
Safety Agency (EASA), which is the Technical Agent for the Member 
States of the European Community, has issued EASA Airworthiness 
Directive 2013-0016, dated January 16, 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 the fatigue tests (EF2) of the Airbus A330 test fuselage, 
initiation and development of cracks were evidenced at the 
circumferential joint of frame 53.3.
    This condition, if not corrected, could lead to a reduction in 
the structural integrity of the fuselage.
    EASA issued AD 2006-0266 [(https://ad.easa.europa.eu/blob/easa_ad_2006_0266_Superseded.pdf/AD_2006-0266_1), which corresponds 
to FAA AD 2007-06-12, Amendment 39-14993 (72 FR 12555, March 16, 
2007)], which took over the requirements of Direction 
G[eacute]n[eacute]rale de L'aviation Civile [DGAC] France AD F-2003-
415 for A330-300 pre-mod 41652S11819, and required reinforcement of 
the circumferential joint of frame 53.3 by application of Airbus 
Service Bulletin (SB) A330-53-3143 on A330-300 post modification 
41652S11819 and pre-mod 49202, and all A330-200 pre-mod 49202 in 
order to improve the fatigue life.
    Since that [EASA] AD was issued, in the frame of a new fatigue 
and damage tolerance evaluation taking into account the aeroplane 
utilisation, the thresholds for the reinforcement were reassessed 
and the conclusion is that some thresholds must be reduced.
    For the reason described above, this [EASA] AD retains the 
requirements of EASA AD 2006-0266, which is superseded, and requires 
reinforcement of structure of the centre fuselage at the upper 
circumferential joint of frame 53.3 within the new thresholds.

    The initial compliance times range between 15,700 total flight 
cycles or 94,600 total flight hours, whichever occurs first; and 25,600 
total flight cycles or 77,000 total flight hours, whichever occurs 
first; depending on airplane configuration. You may examine the MCAI in 
the AD docket on the Internet at https://www.regulations.gov by 
searching for and locating it in Docket No. FAA-2014-0061.

Relevant Service Information

    Airbus has issued Mandatory Service Bulletin A330-53-3127 Revision 
02, including Appendix 01, dated December 7, 2011, and Mandatory 
Service Bulletin A330-53-3143 Revision 05, including Appendix 01, dated 
May 29, 2012. The actions described in this service information are 
intended to correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Repair Approvals

    In many FAA transport ADs, when the service information specifies 
to contact the manufacturer for further instructions if certain 
discrepancies are found, we typically include in the AD a requirement 
to accomplish the action using a method approved by either the FAA or 
the State of Design Authority (or its delegated agent).
    We have recently been notified that certain laws in other countries 
do not allow such delegation of authority, but some countries do 
recognize design approval organizations. In addition, we have become 
aware that some U.S. operators have used repair instructions that were 
previously approved by a State of Design Authority or a Design Approval 
Holder (DAH) as a method of compliance with this provision in FAA ADs. 
Frequently, in these cases, the previously approved repair instructions 
come from the airplane structural repair manual or the DAH repair 
approval statements that were not specifically developed to address the 
unsafe condition corrected by the AD. Using repair instructions that 
were not specifically approved for a particular AD creates the 
potential for doing repairs that were not developed to address the 
unsafe condition identified by the MCAI AD, the FAA AD, or the 
applicable service information, which could result in the unsafe 
condition not being fully corrected.
    To prevent the use of repairs that were not specifically developed 
to correct the unsafe condition, certain requirements of this proposed 
AD would require that the repair approval specifically refer to the FAA 
AD. This change is intended to clarify the method of compliance and to 
provide operators with better visibility of repairs that are 
specifically developed and approved to correct the unsafe condition. In 
addition, we use the phrase ``its delegated agent, or the DAH with 
State of Design Authority design organization approval, as applicable'' 
in this proposed AD to refer to a DAH authorized to approve certain 
required repairs for this proposed AD.

Costs of Compliance

    We estimate that this proposed AD affects 9 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD.

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 proposed AD would not have federalism 
implications under Executive Order 13132. This

[[Page 11018]]

proposed AD would 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 proposed 
regulation:
    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.
