ACTION: Final rule. AGENCY: We are superseding Airworthiness Directive (AD) 2008–08– 04 for certain Airbus Model A318, A319, A320, and A321 series airplanes. AD 2008–08–04 required repetitive inspections for cracking in the forward lug of the support rib 5 fitting of the left and right main landing gear (MLG), and repair or replacement of any cracked MLG fitting if necessary. AD 2008–08– 04 also required modification of the rib bushings of the left and right MLG, which ended the repetitive inspections. This new AD requires, for airplanes on which certain modifications or repairs have been done, repetitive inspections for cracks of the forward lug of each lefthand and right-hand MLG support rib 5 fitting, and repair if necessary; and adds Model A318 series airplanes to the applicability. Replacement of an MLG support rib 5 fitting terminates the repetitive inspection requirements for the MLG support rib 5 fitting at that position. This AD was prompted by reports of cracks found in the forward lug of the MLG support rib 5 fitting. We are issuing this AD to prevent cracking in the forward lug of the MLG, which could result in failure of the lug and consequent collapse of the MLG during takeoff or landing. DATES: This AD becomes effective May 2, 2014. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of May 2, 2014. The Director of the Federal Register approved the incorporation by reference of a certain other publication listed in this AD as of May 19, 2008 (73 FR 19975, April 14, 2008).

SUPPLEMENTARY INFORMATION: tkelley on DSK3SPTVN1PROD with RULES Discussion We issued a supplemental notice of proposed rulemaking (SNPRM) to amend 14 CFR part 39 to supersede AD 2008–08–04, Amendment 39–15456 (73 FR 19975, April 14, 2008). AD 2008–08– 04 applied to certain Airbus Model A318, A319, A320, and A321 series airplanes. The SNPRM published in the Federal Register on October 3, 2012 (77 FR 60325). We preceded the SNPRM with a notice of proposed rulemaking (NPRM) that published in the Federal Register on November 23, 2011 (76 FR 72350). The NPRM proposed to continue to require repetitive inspections for cracking in the forward lug of the support rib 5 fitting of the left and right main landing gear (MLG), and repair or replacement of any cracked MLG fitting if necessary; and modification of the rib bushings of the left and right MLG, which ended the repetitive inspections. The NPRM also proposed to require, for airplanes on which certain modifications or repairs have been done, repetitive inspections for cracks of the forward lug of each lefthand and right-hand MLG support rib 5 fitting, and repair if necessary; and to remove Model A318 series airplanes from the applicability. The NPRM was prompted by reports of cracks found in the forward lug of the MLG support rib 5 fitting. The SNPRM proposed to revise the NPRM by adding Model A318 airplanes and others to the applicability; and requiring repetitive detailed inspections for cracks of the MLG support 5 fitting, and repair of any cracks. We are issuing this AD to prevent cracking in the forward lug of the MLG, which could result in failure VerDate Mar<15>2010 16:20 Mar 27, 2014 Jkt 232001 of the lug and consequent collapse of the MLG during takeoff or landing. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2012–0032, dated February 24, 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: Several cases of corrosion of the Main Landing Gear (MLG) support Rib 5 fitting lug bores have been reported on A320 family aeroplanes. In some instances, corrosion pits caused the cracking of the forward lug (sometimes through its complete thickness). If not detected, the cracking may lead to the complete failure of the fitting and thus could affect the structural integrity of the MLG installation. EASA AD 2007–0213 [(http:// ad.easa.europa.eu/blob/easa_ad_2007_0213_ superseded.pdf/AD_2007–0213_1), which corresponds to FAA AD 2008–08–04, Amendment 39–15456 (73 FR 19975, April 14, 2008)] was issued to address this condition and required a repetitive inspection program of the MLG support Rib 5 fitting forward lugs and, as terminating action, the embodiment of Airbus Service Bulletin (SB) A320–57–1118. After that [EASA] AD was issued, a case of Rib 5, ruptured at the 4 o’clock position, was discovered on an aeroplane on which the terminating action of EASA AD 2007–0213 had already been embodied in accordance with Airbus SB A320–57–1118. Investigation of that case revealed that corrosion damage and cracking that should have been removed by repair machining was below the level of detectability of the Non Destructive Test (NDT) technique that cleared the surfaces prior to bush installation. This condition, if not detected and corrected, could affect the structural integrity of the aeroplane. To correct this potential unsafe condition, EASA issued AD 2011–0011 [(http:// ad.easa.europa.eu/blob/easa_ad_2011_0011_ superseded.pdf/AD_2011–0011_1), which corresponds to FAA AD 2012–15–17 (77 FR 47273, August 8, 2012)], superseding EASA AD 2007–0213, to: —retain the requirements of EASA AD 2007– 0213 for aeroplanes on which the MLG Rib Bushes have not been modified/repaired in accordance with the instructions of Airbus SB A320–57–1118, or Airbus SRM 57–26– 13, or the identified Airbus Repair Instructions, as applicable, and —require, for all aeroplanes on which Airbus SB A320–57–1118 has been embodied in service, or on which Airbus SRM 57–26– 13 or the identified Airbus Repair Instructions have been applied, a repetitive inspection program [for cracks] of the MLG support Rib 5 fitting forward lugs and, depending on findings, the accomplishment of the associated corrective actions, and PO 00000 Frm 00031 Fmt 4700 Sfmt 4700 17417 —reduce the Applicability by deleting A318 aeroplanes, as Airbus modification 32025 is embodied in production on both lefthand (LH) and right-hand (RH) wings for all A318 aeroplanes. After that [EASA] AD was issued, three cases of corrosion of Rib 5 were discovered on aeroplanes on which Airbus modification 32025 had been embodied in production. Investigations revealed that the unsafe condition addressed by [EASA] AD 2011– 0011 could occur or develop on those aeroplanes as well. For the reasons described above, this [EASA] AD retains the requirements of EASA AD 2011–0011, which is superseded, extends the applicability to all aeroplanes, and requires for aeroplanes on which Airbus modification 32025 has been embodied in production, repetitive inspections of the MLG support Rib 5 fitting forward lugs and, depending on findings, the accomplishment of applicable corrective actions. The unsafe condition is cracking in the forward lug of the MLG, which could result in failure of the lug and consequent collapse of the MLG during takeoff or landing. You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/ #!documentDetail;D=FAA-2011-12530002. Comments We gave the public the opportunity to participate in developing this AD. We considered the comments received. Support for the SNPRM (77 FR 60325, October 3, 2012) United Airlines (UAL) stated that it generally agrees with the intent of the SNPRM (77 FR 60325, October 3, 2012). US Airways (AWE) stated that it agrees with the need to add the postmodification inspections, because the mandated bushing modification has not proven to be an effective permanent corrective action. AWE also stated that it agrees with the method and frequency of these additional inspections. Request To Extend Compliance Time UAL requested that we extend the compliance time specified in paragraph (n)(2) of the SNPRM (77 FR 60325, October 3, 2012) from within 2,000 flight cycles after accomplishing the modification or within 250 flight cycles after the effective date of the AD, without exceeding 3 months after the effective date of the AD, whichever occurs later. UAL requested that the compliance time be changed to within 500 flight cycles after the effective date of the AD or within 6 months after the effective date of the AD, whichever occurs later. UAL stated that the majority of its Model A319 and A320 series airplanes have accumulated more than 2,000 flight cycles since E:\FR\FM\28MRR1.SGM 28MRR1 17418 Federal Register / Vol. 79, No. 60 / Friday, March 28, 2014 / Rules and Regulations tkelley on DSK3SPTVN1PROD with RULES accomplishing the modification. UAL stated that it is requesting this change in order to ‘‘reduce the impact due to the special routing required for the inspection,’’ possible MLG removal for repair/replacement of MLG support rib 5 fitting, and a large demand on manpower. UAL stated that extending the compliance time will allow it to perform the required inspection at a more suitable maintenance opportunity. We do not agree with the commenter’s request to extend the compliance time in paragraph (n)(2) of this AD. The commenter did not provide technical justification for extending the compliance time. The compliance time for the actions specified in paragraph (n)(2) in this AD was developed after conducting a risk assessment and analyzing the impact on operators. In consideration of these factors, we determined that the compliance times, as proposed, represent an appropriate interval in which to conduct the inspection after the modification within the fleet, while still maintaining an adequate level of safety. However, under the provisions of paragraph (u) of this AD, we might 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. Requests To Include Revised Service Information Airbus and AWE requested that we add Airbus Mandatory Service Bulletin A320–57–1118, Revision 05, dated July 23, 2012, to paragraph (m) of the SNPRM (77 FR 60325, October 3, 2012). Airbus also requested that we add Airbus Service Bulletin A320–57–1118, Revision 03, dated April 23, 2007; and Revision 04, dated June 4, 2008; to paragraph (t)(5) of the SNPRM. AWE stated that adding Airbus Mandatory Service Bulletin A320–57–1118, Revision 05, dated July 23, 2012, as authorized instructions for modification work would reduce alternative method of compliance coordination. We partially agree with the commenters’ requests. Airbus Mandatory Service Bulletin A320–57– 1118, Revision 05, dated July 23, 2012, states that ‘‘no additional work is required by this revision for airplanes modified by any previous issue.’’ However, this service bulletin revision adds a liquid penetrant inspection. We have added Airbus Mandatory Service Bulletin A320–57–1118, Revision 05, dated July 23, 2012, in paragraph (m) of this final rule as an appropriate source of service information, and specified that the liquid penetrant inspection VerDate Mar<15>2010 16:20 Mar 27, 2014 Jkt 232001 specified in this service information is not required by this AD. We have added paragraphs (t)(5)(iv) and (t)(5)(v) to this final rule to provide credit for certain actions accomplished before May 19, 2008 (the effective date of AD 2008–08– 04, Amendment 39–15456 (73 FR 19975, April 18, 2008)), using Airbus Service Bulletin A320–57–1118, Revision 03, dated April 23, 2007; or Revision 04, dated June 4, 2008. Requests To Change Certain Document References AWE requested we revise the service bulletin reference in the Relevant Service Information section of the SNPRM from ‘‘A320–75–1168’’ to ‘‘A320–57–1168.’’ Airbus requested that we correct references to Airbus Repair Drawings ‘‘R57258209’’ and ‘‘R57245019’’ in paragraph (g)(3) of the SNPRM to Airbus Repair Drawing ‘‘R572–58209’’ and ‘‘R572–45019,’’ respectively. Airbus also requested that we amend paragraph (h)(2) of the SNPRM (77 FR 60325, October 3, 2012) to refer to ‘‘NTM task 57–29–03–270– 801–A–01 for A318/A319/A320 and NTM task 57–29–04–270–801–A–01 for A321 [series airplanes].’’ We agree with the commenters’ requests. The Relevant Service Information section of the SNPRM referenced by AWE is not restated in this final rule; therefore, no change to this final rule is needed in this regard. The content of paragraph (g)(3) of the SNPRM (77 FR 60325, October 3, 2012) referenced by Airbus was located in paragraph (j)(3) of the SNPRM, not in paragraph (g)(3) of the SNPRM, as the commenter specified. We have revised paragraphs (h)(2) and (j)(3) of this final rule accordingly. Request To Include Repair Drawing AWE requested that we include Airbus Repair Drawing R572–48341 in paragraph (g)(2) of the SNPRM (77 FR 60325, October 3, 2012). AWE stated that this drawing is the current and most advanced version of the repair scheme for corrosion and crack findings, and that Airbus issues this drawing when operators request repair design data. AWE also stated that there are still some issues with the details of this repair drawing, but it has collected comments and submitted them to Airbus for incorporation. AWE also noted that Airbus drawing number ‘‘R572481’’ cited (by a different commenter) under ‘‘Request to Reference a Repair Drawing’’ in the preamble of the SNPRM (77 FR 60325, October 3, 2012) should be ‘‘R572– 48341.’’ PO 00000 Frm 00032 Fmt 4700 Sfmt 4700 We disagree with the commenter’s request. The commenter did not provide specific data to substantiate that airplanes repaired with Airbus Repair Drawing R572–48341 would be applicable to the MLG support rib 5 fitting configuration. The commenter also did not provide justification for including a document with potential errors. However, according to the provisions of paragraph (u) of this AD, we might approve requests to include airplanes repaired by Airbus Repair Drawing R572–48341 as an appropriate action for the MLG support rib 5 fitting repair specified in paragraph (j)(2) of this AD. We have not changed this final rule in this regard. Additional Changes Made to This Final Rule We have converted table 1 to paragraph (k) of the SNPRM (77 FR 60325, October 3, 2012) to the text given in paragraphs (k)(1) and (k)(2) of this final rule for formatting purposes only. We have also revised table 2 to paragraph (r)(4) of the SNPRM (77 FR 60325, October 3, 2012) to figure 1 to paragraph (r)(4) of this AD for formatting purposes only. We have revised the citation of the service information referenced in paragraph (t)(2) of the SNPRM (77 FR 60325, October 3, 2012) and moved the service information into new paragraphs (t)(2)(i) and (t)(2)(ii) of this AD. The documents have not changed. Conclusion We reviewed the available data, including the comments 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 SNPRM (77 FR 60325, October 3, 2012) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the SNPRM (77 FR 60325, October 3, 2012). Differences Between This AD and the MCAI or Service Information This AD differs from the MCAI and/ or service information as follows: • Although the MCAI or service information allows further flight after cracks are found during compliance with certain required actions, paragraphs (l) and (p) of this AD require repair or replacement before further flight. • Airbus Mandatory Service Bulletin A320–57–1118, Revision 05, dated July E:\FR\FM\28MRR1.SGM 28MRR1 Federal Register / Vol. 79, No. 60 / Friday, March 28, 2014 / Rules and Regulations 23, 2012, describes a liquid penetrant inspection. This AD does not require that inspection. Costs of Compliance We estimate that this AD will affect about 740 products of U.S. registry. The actions that are required by AD 2008–08–04, Amendment 39–15456 (73 FR 19975, April 14, 2008), and retained in this AD take about 73 work-hours per product, at an average labor rate of $85 per work-hour. Required parts cost about $3,860 per product. Based on these figures, the estimated cost of the currently required actions is $10,065 per product. We estimate that it will take about 3 work-hours per product to comply with the new basic requirements of this AD. The average labor rate is $85 per workhour. Based on these figures, we estimate the cost of this AD to the U.S. operators to be up to $188,700, or $255 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. tkelley on DSK3SPTVN1PROD 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. 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; VerDate Mar<15>2010 16:20 Mar 27, 2014 Jkt 232001 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 are issuing this AD to prevent cracking in the forward lug of the MLG, which could result in failure of the lug and consequent collapse of the MLG during takeoff or landing. (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) Retained Repetitive Detailed Inspections With Changes This paragraph restates the requirements of paragraph (f) of AD 2008–08–04, Amendment 39–15456 (73 FR 19975, April 14, 2008), with changes. Except for airplanes on which Airbus modification 32025 has been accomplished in production, within 8 days after June 7, 2006 (the effective date of AD 2006–11–04, Amendment 39–14608 (71 FR 29578, May 23, 2006)), or before further flight after a hard landing, whichever is first: Perform a detailed inspection for cracking in the forward lug of the support rib 5 fitting of the left- and right-hand MLG, and, if any crack is found, replace the MLG fitting with a new fitting before further flight, in accordance with a method approved by the Manager, International Branch, ANM–116, Transport Airplane Directorate, FAA, or the European Aviation Safety Agency (EASA) (or its delegated agent). Repeat the inspection thereafter at intervals not to exceed 8 days, or before further flight after a hard landing, whichever is first. As of May 19, 2008 (the effective date of AD 2008–08–04), the repetitive inspections required by paragraph (k) of this AD must be accomplished in lieu of the repetitive inspections required by this paragraph.

ACTION: Final rule. tkelley on DSK3SPTVN1PROD with RULES AGENCY: The Danny Keysar Child Product Safety Notification Act, section 104 of the Consumer Product Safety Improvement Act of 2008 (CPSIA), requires the United States Consumer SUMMARY: VerDate Mar<15>2010 16:20 Mar 27, 2014 Jkt 232001 Product Safety Commission (Commission, CPSC, or we) to promulgate consumer product safety standards for durable infant or toddler products. Durable infant and toddler standards must be ‘‘substantially the same as’’ applicable voluntary standards or more stringent than the voluntary standard if the Commission concludes that more stringent requirements would further reduce the risk of injury associated with the product. The Commission is issuing this final rule establishing a safety standard for soft infant and toddler carriers in response to the direction under section 104(b) of the CPSIA. DATES: The rule will become effective September 29, 2014 and apply to product manufactured or imported on or after that date. The incorporation by reference of the publication listed in this rule is approved by the Director of the Federal Register as of September 29, 2014. FOR FURTHER INFORMATION CONTACT: Julio A. Alvarado, Office of Compliance and Field Operations, Consumer Product Safety Commission, 4330 East West Highway, Bethesda, MD 20814; telephone: 301–504–7418; email: jalvarado@cpsc.gov. SUPPLEMENTARY INFORMATION: I. Background and Statutory Authority The Consumer Product Safety Improvement Act of 2008 (CPSIA, Pub L. 110–314) was enacted on August 14, 2008. Section 104(b) of the CPSIA, part of the Danny Keysar Child Product Safety Notification Act, requires the Commission to: (1) Examine and assess the effectiveness of voluntary consumer product safety standards for durable infant or toddler products, in consultation with representatives of consumer groups, juvenile product manufacturers, and independent child product engineers and experts; and (2) promulgate consumer product safety standards for durable infant and toddler products. Durable infant and toddler standards must be ‘‘substantially the same as’’ applicable voluntary standards or more stringent than the voluntary standard if the Commission concludes that more stringent requirements would further reduce the risk of injury associated with the product. The term ‘‘durable infant or toddler product’’ is defined in section 104(f)(1) of the CPSIA as ‘‘a durable product intended for use, or that may be reasonably expected to be used, by children under the age of 5 years.’’ Section 104(f)(2)(H) of the CPSIA specifically identifies ‘‘infant carriers’’ as durable infant or toddler products. PO 00000 Frm 00036 Fmt 4700 Sfmt 4700 The Commission has identified at least four types of products that fall within the product category of ‘‘infant carriers,’’ including: Frame backpack carriers, hand-held infant carriers, slings, and soft infant and toddler carriers. On April 5, 2013, the Commission issued a notice of proposed rulemaking (NPR) for soft infant and toddler carriers. 78 FR 20511. The NPR proposed to adopt as a mandatory standard the current voluntary standard for soft infant and toddler carriers, ASTM F2236–13, ‘‘Standard Consumer Safety Specification for Soft Infant and Toddler Carriers’’ (ASTM F2236–13), without alteration. The Commission is issuing a final mandatory safety standard for soft infant and toddler carriers. Pursuant to section 104(b)(1)(A) of the CPSIA, the Commission consulted with manufacturers, retailers, trade organizations, laboratories, consumer advocacy groups, consultants, and members of the public to develop this standard, largely through the ASTM process. After publication of the NPR, ASTM approved two revised versions of F2236–13, F2236–13a, on November 1, 2013, and F2236–14, on January 1, 2014. The revisions included in ASTM F2236–14 clarify several issues raised in the comments received on the NPR. Furthermore, the Commission finds that the revisions included in ASTM F2236– 14 adequately address the comments received on the NPR. Section V of the preamble below discusses clarifying changes to the standard. The final rule for soft infant and toddler carriers incorporates ASTM F2236–14, by reference, without alteration. II. Product Description A. Definition of a Soft Infant and Toddler Carrier ASTM F2236–14 defines a ‘‘soft infant and toddler carrier’’ as ‘‘a product, normally of sewn fabric construction, which is designed to contain a full term infant to a toddler, generally in an upright position, in close proximity to the caregiver.’’ Additionally, soft infant and toddler carriers are generally designed to carry a child ‘‘between 7 and 45 pounds.’’ ASTM F2236–14 explains that soft infant and toddler carriers are ‘‘normally ‘worn’ by the caregiver with a child positioned in the carrier and the weight of the child and carrier suspended from one or both shoulders of the caregiver. These products may be worn on the front, side, or back of the caregiver’s body, with the infant either facing towards or away from the caregiver.’’ Typically, children E:\FR\FM\28MRR1.SGM 28MRR1

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2008-08-04 for 
certain Airbus Model A318, A319, A320, and A321 series airplanes. AD 
2008-08-04 required repetitive inspections for cracking in the forward 
lug of the support rib 5 fitting of the left and right main landing 
gear (MLG), and repair or replacement of any cracked MLG fitting if 
necessary. AD 2008-08-04 also required modification of the rib bushings 
of the left and right MLG, which ended the repetitive inspections. This 
new AD requires, for airplanes on which certain modifications or 
repairs have been done, repetitive inspections for cracks of the 
forward lug of each left-hand and right-hand MLG support rib 5 fitting, 
and repair if necessary; and adds Model A318 series airplanes to the 
applicability. Replacement of an MLG support rib 5 fitting terminates 
the repetitive inspection requirements for the MLG support rib 5 
fitting at that position. This AD was prompted by reports of cracks 
found in the forward lug of the MLG support rib 5 fitting. We are 
issuing this AD to prevent cracking in the forward lug of the MLG, 
which could result in failure of the lug and consequent collapse of the 
MLG during takeoff or landing.

DATES: This AD becomes effective May 2, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of May 2, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of a certain other publication listed in this AD as of May 
19, 2008 (73 FR 19975, April 14, 2008).

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a supplemental notice of proposed rulemaking (SNPRM) to 
amend 14 CFR part 39 to supersede AD 2008-08-04, Amendment 39-15456 (73 
FR 19975, April 14, 2008). AD 2008-08-04 applied to certain Airbus 
Model A318, A319, A320, and A321 series airplanes. The SNPRM published 
in the Federal Register on October 3, 2012 (77 FR 60325). We preceded 
the SNPRM with a notice of proposed rulemaking (NPRM) that published in 
the Federal Register on November 23, 2011 (76 FR 72350). The NPRM 
proposed to continue to require repetitive inspections for cracking in 
the forward lug of the support rib 5 fitting of the left and right main 
landing gear (MLG), and repair or replacement of any cracked MLG 
fitting if necessary; and modification of the rib bushings of the left 
and right MLG, which ended the repetitive inspections. The NPRM also 
proposed to require, for airplanes on which certain modifications or 
repairs have been done, repetitive inspections for cracks of the 
forward lug of each left-hand and right-hand MLG support rib 5 fitting, 
and repair if necessary; and to remove Model A318 series airplanes from 
the applicability. The NPRM was prompted by reports of cracks found in 
the forward lug of the MLG support rib 5 fitting. The SNPRM proposed to 
revise the NPRM by adding Model A318 airplanes and others to the 
applicability; and requiring repetitive detailed inspections for cracks 
of the MLG support 5 fitting, and repair of any cracks. We are issuing 
this AD to prevent cracking in the forward lug of the MLG, which could 
result in failure of the lug and consequent collapse of the MLG during 
takeoff or landing.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2012-0032, dated February 24, 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:

    Several cases of corrosion of the Main Landing Gear (MLG) 
support Rib 5 fitting lug bores have been reported on A320 family 
aeroplanes. In some instances, corrosion pits caused the cracking of 
the forward lug (sometimes through its complete thickness). If not 
detected, the cracking may lead to the complete failure of the 
fitting and thus could affect the structural integrity of the MLG 
installation.
    EASA AD 2007-0213 [(http://ad.easa.europa.eu/blob/easa_ad_2007_0213_superseded.pdf/AD_2007-0213_1), which corresponds to 
FAA AD 2008-08-04, Amendment 39-15456 (73 FR 19975, April 14, 2008)] 
was issued to address this condition and required a repetitive 
inspection program of the MLG support Rib 5 fitting forward lugs 
and, as terminating action, the embodiment of Airbus Service 
Bulletin (SB) A320-57-1118.
    After that [EASA] AD was issued, a case of Rib 5, ruptured at 
the 4 o'clock position, was discovered on an aeroplane on which the 
terminating action of EASA AD 2007-0213 had already been embodied in 
accordance with Airbus SB A320-57-1118.
    Investigation of that case revealed that corrosion damage and 
cracking that should have been removed by repair machining was below 
the level of detectability of the Non Destructive Test (NDT) 
technique that cleared the surfaces prior to bush installation.
    This condition, if not detected and corrected, could affect the 
structural integrity of the aeroplane.
    To correct this potential unsafe condition, EASA issued AD 2011-
0011 [(http://ad.easa.europa.eu/blob/easa_ad_2011_0011_superseded.pdf/AD_2011-0011_1), which corresponds to FAA AD 2012-
15-17 (77 FR 47273, August 8, 2012)], superseding EASA AD 2007-0213, 
to:

--retain the requirements of EASA AD 2007-0213 for aeroplanes on 
which the MLG Rib Bushes have not been modified/repaired in 
accordance with the instructions of Airbus SB A320-57-1118, or 
Airbus SRM 57-26-13, or the identified Airbus Repair Instructions, 
as applicable, and
--require, for all aeroplanes on which Airbus SB A320-57-1118 has 
been embodied in service, or on which Airbus SRM 57-26-13 or the 
identified Airbus Repair Instructions have been applied, a 
repetitive inspection program [for cracks] of the MLG support Rib 5 
fitting forward lugs and, depending on findings, the accomplishment 
of the associated corrective actions, and
--reduce the Applicability by deleting A318 aeroplanes, as Airbus 
modification 32025 is embodied in production on both left-hand (LH) 
and right-hand (RH) wings for all A318 aeroplanes.

    After that [EASA] AD was issued, three cases of corrosion of Rib 
5 were discovered on aeroplanes on which Airbus modification 32025 
had been embodied in production. Investigations revealed that the 
unsafe condition addressed by [EASA] AD 2011-0011 could occur or 
develop on those aeroplanes as well.
    For the reasons described above, this [EASA] AD retains the 
requirements of EASA AD 2011-0011, which is superseded, extends the 
applicability to all aeroplanes, and requires for aeroplanes on 
which Airbus modification 32025 has been embodied in production, 
repetitive inspections of the MLG support Rib 5 fitting forward lugs 
and, depending on findings, the accomplishment of applicable 
corrective actions.

The unsafe condition is cracking in the forward lug of the MLG, which 
could result in failure of the lug and consequent collapse of the MLG 
during takeoff or landing. You may examine the MCAI in the AD docket on 
the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2011-
1253-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the comments received.

Support for the SNPRM (77 FR 60325, October 3, 2012)

    United Airlines (UAL) stated that it generally agrees with the 
intent of the SNPRM (77 FR 60325, October 3, 2012).
    US Airways (AWE) stated that it agrees with the need to add the 
post-modification inspections, because the mandated bushing 
modification has not proven to be an effective permanent corrective 
action. AWE also stated that it agrees with the method and frequency of 
these additional inspections.

Request To Extend Compliance Time

    UAL requested that we extend the compliance time specified in 
paragraph (n)(2) of the SNPRM (77 FR 60325, October 3, 2012) from 
within 2,000 flight cycles after accomplishing the modification or 
within 250 flight cycles after the effective date of the AD, without 
exceeding 3 months after the effective date of the AD, whichever occurs 
later. UAL requested that the compliance time be changed to within 500 
flight cycles after the effective date of the AD or within 6 months 
after the effective date of the AD, whichever occurs later. UAL stated 
that the majority of its Model A319 and A320 series airplanes have 
accumulated more than 2,000 flight cycles since

[[Page 17418]]

accomplishing the modification. UAL stated that it is requesting this 
change in order to ``reduce the impact due to the special routing 
required for the inspection,'' possible MLG removal for repair/
replacement of MLG support rib 5 fitting, and a large demand on man-
power. UAL stated that extending the compliance time will allow it to 
perform the required inspection at a more suitable maintenance 
opportunity.
    We do not agree with the commenter's request to extend the 
compliance time in paragraph (n)(2) of this AD. The commenter did not 
provide technical justification for extending the compliance time. The 
compliance time for the actions specified in paragraph (n)(2) in this 
AD was developed after conducting a risk assessment and analyzing the 
impact on operators. In consideration of these factors, we determined 
that the compliance times, as proposed, represent an appropriate 
interval in which to conduct the inspection after the modification 
within the fleet, while still maintaining an adequate level of safety. 
However, under the provisions of paragraph (u) of this AD, we might 
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.

Requests To Include Revised Service Information

    Airbus and AWE requested that we add Airbus Mandatory Service 
Bulletin A320-57-1118, Revision 05, dated July 23, 2012, to paragraph 
(m) of the SNPRM (77 FR 60325, October 3, 2012). Airbus also requested 
that we add Airbus Service Bulletin A320-57-1118, Revision 03, dated 
April 23, 2007; and Revision 04, dated June 4, 2008; to paragraph 
(t)(5) of the SNPRM. AWE stated that adding Airbus Mandatory Service 
Bulletin A320-57-1118, Revision 05, dated July 23, 2012, as authorized 
instructions for modification work would reduce alternative method of 
compliance coordination.
    We partially agree with the commenters' requests. Airbus Mandatory 
Service Bulletin A320-57-1118, Revision 05, dated July 23, 2012, states 
that ``no additional work is required by this revision for airplanes 
modified by any previous issue.'' However, this service bulletin 
revision adds a liquid penetrant inspection. We have added Airbus 
Mandatory Service Bulletin A320-57-1118, Revision 05, dated July 23, 
2012, in paragraph (m) of this final rule as an appropriate source of 
service information, and specified that the liquid penetrant inspection 
specified in this service information is not required by this AD. We 
have added paragraphs (t)(5)(iv) and (t)(5)(v) to this final rule to 
provide credit for certain actions accomplished before May 19, 2008 
(the effective date of AD 2008-08-04, Amendment 39-15456 (73 FR 19975, 
April 18, 2008)), using Airbus Service Bulletin A320-57-1118, Revision 
03, dated April 23, 2007; or Revision 04, dated June 4, 2008.

Requests To Change Certain Document References

    AWE requested we revise the service bulletin reference in the 
Relevant Service Information section of the SNPRM from ``A320-75-1168'' 
to ``A320-57-1168.'' Airbus requested that we correct references to 
Airbus Repair Drawings ``R57258209'' and ``R57245019'' in paragraph 
(g)(3) of the SNPRM to Airbus Repair Drawing ``R572-58209'' and ``R572-
45019,'' respectively. Airbus also requested that we amend paragraph 
(h)(2) of the SNPRM (77 FR 60325, October 3, 2012) to refer to ``NTM 
task 57-29-03-270-801-A-01 for A318/A319/A320 and NTM task 57-29-04-
270-801-A-01 for A321 [series airplanes].''
    We agree with the commenters' requests. The Relevant Service 
Information section of the SNPRM referenced by AWE is not restated in 
this final rule; therefore, no change to this final rule is needed in 
this regard. The content of paragraph (g)(3) of the SNPRM (77 FR 60325, 
October 3, 2012) referenced by Airbus was located in paragraph (j)(3) 
of the SNPRM, not in paragraph (g)(3) of the SNPRM, as the commenter 
specified. We have revised paragraphs (h)(2) and (j)(3) of this final 
rule accordingly.

Request To Include Repair Drawing

    AWE requested that we include Airbus Repair Drawing R572-48341 in 
paragraph (g)(2) of the SNPRM (77 FR 60325, October 3, 2012). AWE 
stated that this drawing is the current and most advanced version of 
the repair scheme for corrosion and crack findings, and that Airbus 
issues this drawing when operators request repair design data. AWE also 
stated that there are still some issues with the details of this repair 
drawing, but it has collected comments and submitted them to Airbus for 
incorporation. AWE also noted that Airbus drawing number ``R572481'' 
cited (by a different commenter) under ``Request to Reference a Repair 
Drawing'' in the preamble of the SNPRM (77 FR 60325, October 3, 2012) 
should be ``R572-48341.''
    We disagree with the commenter's request. The commenter did not 
provide specific data to substantiate that airplanes repaired with 
Airbus Repair Drawing R572-48341 would be applicable to the MLG support 
rib 5 fitting configuration. The commenter also did not provide 
justification for including a document with potential errors. However, 
according to the provisions of paragraph (u) of this AD, we might 
approve requests to include airplanes repaired by Airbus Repair Drawing 
R572-48341 as an appropriate action for the MLG support rib 5 fitting 
repair specified in paragraph (j)(2) of this AD. We have not changed 
this final rule in this regard.

Additional Changes Made to This Final Rule

    We have converted table 1 to paragraph (k) of the SNPRM (77 FR 
60325, October 3, 2012) to the text given in paragraphs (k)(1) and 
(k)(2) of this final rule for formatting purposes only.
    We have also revised table 2 to paragraph (r)(4) of the SNPRM (77 
FR 60325, October 3, 2012) to figure 1 to paragraph (r)(4) of this AD 
for formatting purposes only.
    We have revised the citation of the service information referenced 
in paragraph (t)(2) of the SNPRM (77 FR 60325, October 3, 2012) and 
moved the service information into new paragraphs (t)(2)(i) and 
(t)(2)(ii) of this AD. The documents have not changed.

Conclusion

    We reviewed the available data, including the comments 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 
SNPRM (77 FR 60325, October 3, 2012) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the SNPRM (77 FR 60325, October 3, 2012).

Differences Between This AD and the MCAI or Service Information

    This AD differs from the MCAI and/or service information as 
follows:
     Although the MCAI or service information allows further 
flight after cracks are found during compliance with certain required 
actions, paragraphs (l) and (p) of this AD require repair or 
replacement before further flight.
     Airbus Mandatory Service Bulletin A320-57-1118, Revision 
05, dated July

[[Page 17419]]

23, 2012, describes a liquid penetrant inspection. This AD does not 
require that inspection.

Costs of Compliance

    We estimate that this AD will affect about 740 products of U.S. 
registry.
    The actions that are required by AD 2008-08-04, Amendment 39-15456 
(73 FR 19975, April 14, 2008), and retained in this AD take about 73 
work-hours per product, at an average labor rate of $85 per work-hour. 
Required parts cost about $3,860 per product. Based on these figures, 
the estimated cost of the currently required actions is $10,065 per 
product.
    We estimate that it will take about 3 work-hours per product to 
comply with the new 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 to the U.S. operators to be up to $188,700, or $255 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.

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.

certificated in any category, all manufacturer serial numbers.

(d) Subject

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

(e) Reason

    This AD was prompted by reports of cracks found in the forward 
lug of the main landing gear (MLG) support rib 5 fitting. We are 
issuing this AD to prevent cracking in the forward lug of the MLG, 
which could result in failure of the lug and consequent collapse of 
the MLG during takeoff or landing.

(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) Retained Repetitive Detailed Inspections With Changes

    This paragraph restates the requirements of paragraph (f) of AD 
2008-08-04, Amendment 39-15456 (73 FR 19975, April 14, 2008), with 
changes. Except for airplanes on which Airbus modification 32025 has 
been accomplished in production, within 8 days after June 7, 2006 
(the effective date of AD 2006-11-04, Amendment 39-14608 (71 FR 
29578, May 23, 2006)), or before further flight after a hard 
landing, whichever is first: Perform a detailed inspection for 
cracking in the forward lug of the support rib 5 fitting of the 
left- and right-hand MLG, and, if any crack is found, replace the 
MLG fitting with a new fitting before further flight, in accordance 
with a method approved by the Manager, International Branch, ANM-
116, Transport Airplane Directorate, FAA, or the European Aviation 
Safety Agency (EASA) (or its delegated agent). Repeat the inspection 
thereafter at intervals not to exceed 8 days, or before further 
flight after a hard landing, whichever is first. As of May 19, 2008 
(the effective date of AD 2008-08-04), the repetitive inspections 
required by paragraph (k) of this AD must be accomplished in lieu of 
the repetitive inspections required by this paragraph.

(h) Retained Optional Inspection Method With Revised Service 
Information

    This paragraph restates the provisions of paragraph (g) of AD 
2008-08-04, Amendment 39-15456 (73 FR 19975, April 14, 2008), with 
revised service information. Performing an ultrasonic inspection for 
cracking in the forward lug of the support rib 5 fitting of the 
left- and right-hand MLG, in accordance with an applicable method 
specified in paragraph (h)(1) or (h)(2) of this AD, is an acceptable 
alternative method of compliance for the initial and repetitive 
inspections required by paragraph (g) of this AD.
    (1) In accordance with a method approved by the Manager, 
International Branch, ANM-116, or the EASA (or its delegated agent).
    (2) In accordance with Task 57-29-03-270-801-A-01, Gear Rib 
Forward Lug Attachment for the Main Gear Before Modification 
32025J2211, of Subject 57-29-03, Inspection of the Gear Rib Forward 
and

series airplanes); or Task 57-29-04-270-801-A-01, Gear Rib Forward 
Lug Attachment for the Main Gear Before Modification 32025J2211, of 
Subject 57-29-04, Inspection of the Gear Rib Forward and Aft Lug 
Attachment for the Main Gear (for Model A321 series airplanes); both 
of Chapter 57, Wings, of the Airbus A318/A319/A320/A321 
Nondestructive Testing Manual, Revision 89, dated August 1, 2011.

(i) Retained Optional Terminating Action With Changes

    This paragraph restates the provisions of paragraph (h) of AD 
2008-08-04, Amendment 39-15456 (73 FR 19975, April 14, 2008), with 
changes. Repair of the forward lugs of the support rib 5 fitting of 
the left- and right-hand MLG done before the effective date of this 
AD, in accordance with a method approved by the Manager, 
International Branch, ANM-116, or the EASA (or its delegated agent), 
constitutes terminating action for the requirements of paragraphs 
(g), (h), (k), (l), and (m) of this AD.

(j) New Referenced Conditions With Revised Affected Airplanes
