ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for certain Airbus Model A320–211, –212, –214, –231, –232, and –233 airplanes. This AD was prompted by a report of cracking at the splice plate of the frame (FR) 47 butt joint crossing area found during fullscale fatigue testing. This AD requires repetitive inspections for cracking of both sides of the splice plate of that frame butt joint crossing area, and corrective action if necessary. This AD also provides for an optional modification, which terminates the repetitive inspections. We are issuing this AD to detect and correct fatigue cracking of the splice plate of the FR 47 butt joint crossing area, which could result in reduced structural integrity of the airplane. DATES: This AD becomes effective January 20, 2015.

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 A320– 211, –212, –214, –231, –232, and –233 airplanes. The NPRM published in the Federal Register on July 18, 2014 (79 FR 41940). The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2013–0203, dated September 6, 2013 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Airbus Model A320–211, –212, –214, –231, –232, and –233 airplanes. The MCAI states: During the full scale fatigue test on A320– 200, cracks were reported at the splice plate of the frame (FR) 47 butt joint crossing area, both sides. This condition, if not detected and corrected, could affect the structural integrity of the aeroplane. Prompted by these findings, Airbus developed Mod 31012 and introduced this on the production line to modify the current 2 fastener row butt joint into a 3 fastener row butt joint to prevent further damage. For inservice aeroplanes, a corresponding modification was developed and published E:\FR\FM\16DER1.SGM 16DER1 74598 Federal Register / Vol. 79, No. 241 / Tuesday, December 16, 2014 / Rules and Regulations as Airbus Service Bulletin (SB) A320–53– 1271. For the reason described above, this [EASA] AD requires repetitive special detailed inspections (SDI) of the splice plate of the FR47 butt joint crossing area and, depending on findings, accomplishment of applicable corrective action(s). You may examine the MCAI in the AD docket on the Internet at http:// www.regulations.gov/#!documentDetail; D=FAA-2014-0453-0002. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comment received on the NPRM (79 FR 41940, July 18, 2014) and the FAA’s response. Request to Extend the Compliance Time Allegiant Air, LLC asked that we extend the threshold for the initial inspection for the airplanes identified in paragraph (g)(3) of the proposed AD (79 FR 41940, July 18, 2014) to 44,000 flight cycles or 88,000 flight hours, whichever occurs first. Allegiant Air asserted that an equivalent level of safety would be maintained by extending the compliance time as proposed. Allegiant Air noted that paragraph (g)(2) of the proposed AD specified a threshold of 45,000 total flight cycles or 91,000 total flight hours, whichever occurs first. We do not agree with the commenter’s request to extend the compliance time. We infer that Allegiant Air, LLC expected 44,000 total flight cycles or 88,000 total flight hours to be the threshold for crack growth propagation based on full-scale fatigue testing; however, Allegiant Air, LLC did not provide data to support this inference. Based on our risk assessment, taking into consideration the worldwide fleet utilization, as well as fatigue and crack growth analysis, we have determined that the compliance time specified in paragraph (g)(3) of this AD will ensure an acceptable level of safety and allow the inspections to be done in a timely manner. However, under the provisions of paragraph (j) of this AD, we may approve requests for adjustments to the compliance time if data are submitted to substantiate that such an adjustment would provide an acceptable level of safety. We have not changed this final rule in this regard. tkelley on DSK3SPTVN1PROD with RULES Conclusion We reviewed the relevant data, considered the comment received, 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: VerDate Sep<11>2014 16:25 Dec 15, 2014 Jkt 235001 • Are consistent with the intent that was proposed in the NPRM (79 FR 41940, July 18, 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 41940, July 18, 2014). Costs of Compliance We estimate that this AD affects 229 airplanes of U.S. registry. We also estimate that it will take about 98 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this AD on U.S. operators to be $1,907,570, or $8,330 per product. We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this AD. In addition, we estimate that any necessary follow-on actions take about 100 work-hours and require parts costing $1,150, for a cost of $9,650 per product. We have no way of determining the number of aircraft that might need these actions. 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: PO 00000 Frm 00014 Fmt 4700 Sfmt 4700 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.

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Airbus Model A320-211, -212, -214, -231, -232, and -233 airplanes. This 
AD was prompted by a report of cracking at the splice plate of the 
frame (FR) 47 butt joint crossing area found during full-scale fatigue 
testing. This AD requires repetitive inspections for cracking of both 
sides of the splice plate of that frame butt joint crossing area, and 
corrective action if necessary. This AD also provides for an optional 
modification, which terminates the repetitive inspections. We are 
issuing this AD to detect and correct fatigue cracking of the splice 
plate of the FR 47 butt joint crossing area, which could result in 
reduced structural integrity of the airplane.

DATES: This AD becomes effective January 20, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of January 20,

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 A320-
211, -212, -214, -231, -232, and -233 airplanes. The NPRM published in 
the Federal Register on July 18, 2014 (79 FR 41940).
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2013-0203, dated September 6, 2013 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for certain Airbus Model 
A320-211, -212, -214, -231, -232, and -233 airplanes. The MCAI states:

    During the full scale fatigue test on A320-200, cracks were 
reported at the splice plate of the frame (FR) 47 butt joint 
crossing area, both sides.
    This condition, if not detected and corrected, could affect the 
structural integrity of the aeroplane.
    Prompted by these findings, Airbus developed Mod 31012 and 
introduced this on the production line to modify the current 2 
fastener row butt joint into a 3 fastener row butt joint to prevent 
further damage. For in-service aeroplanes, a corresponding 
modification was developed and published

[[Page 74598]]

as Airbus Service Bulletin (SB) A320-53-1271.
    For the reason described above, this [EASA] AD requires 
repetitive special detailed inspections (SDI) of the splice plate of 
the FR47 butt joint crossing area and, depending on findings, 
accomplishment of applicable corrective action(s).

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2014-0453-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comment received on the NPRM (79 FR 
41940, July 18, 2014) and the FAA's response.

Request to Extend the Compliance Time

    Allegiant Air, LLC asked that we extend the threshold for the 
initial inspection for the airplanes identified in paragraph (g)(3) of 
the proposed AD (79 FR 41940, July 18, 2014) to 44,000 flight cycles or 
88,000 flight hours, whichever occurs first. Allegiant Air asserted 
that an equivalent level of safety would be maintained by extending the 
compliance time as proposed. Allegiant Air noted that paragraph (g)(2) 
of the proposed AD specified a threshold of 45,000 total flight cycles 
or 91,000 total flight hours, whichever occurs first.
    We do not agree with the commenter's request to extend the 
compliance time. We infer that Allegiant Air, LLC expected 44,000 total 
flight cycles or 88,000 total flight hours to be the threshold for 
crack growth propagation based on full-scale fatigue testing; however, 
Allegiant Air, LLC did not provide data to support this inference. 
Based on our risk assessment, taking into consideration the worldwide 
fleet utilization, as well as fatigue and crack growth analysis, we 
have determined that the compliance time specified in paragraph (g)(3) 
of this AD will ensure an acceptable level of safety and allow the 
inspections to be done in a timely manner. However, under the 
provisions of paragraph (j) of this AD, we may approve requests for 
adjustments to the compliance time if data are submitted to 
substantiate that such an adjustment would provide an acceptable level 
of safety. We have not changed this final rule in this regard.

Conclusion

    We reviewed the relevant data, considered the comment received, 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 (79 FR 41940, July 18, 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 41940, July 18, 2014).

Costs of Compliance

    We estimate that this AD affects 229 airplanes of U.S. registry.
    We also estimate that it will take about 98 work-hours per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85 per work-hour. Based on these figures, we estimate the cost 
of this AD on U.S. operators to be $1,907,570, or $8,330 per product.
    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this AD.
    In addition, we estimate that any necessary follow-on actions take 
about 100 work-hours and require parts costing $1,150, for a cost of 
$9,650 per product. We have no way of determining the number of 
aircraft that might need these actions.

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.

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

2014-25-07 Airbus: Amendment 39-18049. Docket No. FAA-2014-0453; 
Directorate Identifier 2013-NM-205-AD.

(a) Effective Date

    This AD becomes effective January 20, 2015.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Airbus Model A320-211, -212, -214, -231, -
232, and -233 airplanes, certificated in any category, all 
manufacturer serial numbers, except those on which Airbus 
Modification 31012 has been embodied in production.

[[Page 74599]]

(d) Subject

    Air Transport Association (ATA) of America Code 53, Fuselage.

(e) Reason

    This AD was prompted by a report of cracking at the splice plate 
of the frame (FR) 47 butt joint crossing area found during full-
scale fatigue testing. We are issuing this AD to detect and correct 
fatigue cracking of the splice plate of the FR47 butt joint crossing 
area, which could result in reduced structural integrity of the 
airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Repetitive Inspections

    At the applicable time specified in paragraph (g)(1), (g)(2), or 
(g)(3) of this AD: Do a special detailed inspection (rototest) for 
cracking of both sides of the splice plate of the FR47 butt joint 
crossing area, in accordance with the Accomplishment Instructions of 
Airbus Service Bulletin A320-53-1260, dated December 19, 2012. 
Repeat the inspection thereafter at intervals not to exceed 14,800 
flight cycles or 29,600 flight hours, whichever occurs first.
    (1) For airplanes that, as of the effective date of this AD, 
have accumulated 44,000 or more total flight cycles or 88,000 or 
more total flight hours since first flight of the airplane: Do the 
inspection within 1,500 flight cycles or 3,000 flight hours after 
the effective date of this AD, whichever occurs first.
    (2) For airplanes that, as of the effective date of this AD, 
have accumulated 27,700 or more total flight cycles or 55,400 or 
more total flight hours, but fewer than 44,000 total flight cycles 
or 88,000 total flight hours since first flight of the airplane: Do 
the inspection within 3,000 flight cycles or 6,000 flight hours 
after the effective date of this AD, without exceeding 45,500 total 
flight cycles or 91,000 total flight hours since first flight of the 
airplane, whichever occurs first.
    (3) For airplanes that, as of the effective date of this AD, 
have accumulated fewer than 27,700 total flight cycles and less than 
55,400 total flight hours since first flight of the airplane: Do the 
inspection before the accumulation of 30,700 total flight cycles or 
61,400 total flight hours since first flight of the airplane, 
whichever occurs first.

(h) Corrective Action

    If any crack is found during any inspection required by this AD: 
Before further flight, repair using a method approved by the 
Manager, International Branch, ANM-116, Transport Airplane 
Directorate, FAA; or the European Aviation Safety Agency (EASA); or 
Airbus's EASA Design Organization Approval (DOA). If approved by the 
DOA, the approval must include the DOA-authorized signature.

(i) Optional Modification

    Accomplishing the modification of the splice plate of the FR47 
butt joint in accordance with the Accomplishment Instructions of 
Airbus Service Bulletin A320-53-1271, dated December 18, 2012, 
constitutes terminating action for the repetitive inspections 
required by paragraph (g) of this AD.
