[FR Doc. 2014–05426 Filed 3–11–14; 8:45 am] BILLING CODE 4910–13–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2014–0142; Directorate Identifier 2012–NM–161–AD] RIN 2120–AA64 Airworthiness Directives; Airbus Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to supersede Airworthiness Directive (AD) 2008–17– 02, AD 2012–08–03, and AD 2012–15– 14, for certain Airbus Model A300 B4– 2C, B4–103, and B4–203 airplanes; Model A300 B4–600, B4–600R, and F4– 600R series airplanes, and Model C4– 605R Variant F airplanes (collectively called A300–600 series airplanes); and Model A310 series airplanes. AD 2008– 17–02, AD 2012–08–03, and AD 2012– 15–14 currently require repetitive inspections of the forward lugs of the aft bearing at rib 5 of the main landing gear (MLG) on the left-hand (LH) and righthand (RH) wings, and repair if necessary; and installation of new bushes with increased interference fit in the forward lug of the aft bearing at rib 5 of the MLG on the LH and RH wings. Since we issued AD 2008–17–02, AD 2012–08–03, and AD 2012–15–14, we have received two reports of ruptured MLG rib 5 forward lugs that had been modified (bushes with increased interference fit). This proposed AD would add airplanes to the applicability; and would add, for certain tkelley on DSK3SPTVN1PROD with PROPOSALS SUMMARY: VerDate Mar<15>2010 17:07 Mar 11, 2014 Jkt 232001 airplanes, repetitive inspections of the MLG rib 5 aft bearing forward lugs, and repair if necessary. We are proposing this AD to detect and correct cracking of the forward lugs of the aft bearing at rib 5 of the MLG on the LH and RH wings, which could affect the structural integrity of the MLG attachment, resulting in possible MLG collapse during landing or rollout.

Discussion On July 31, 2008, we issued AD 2008– 17–02, Amendment 39–15640 (73 FR 47032, August 13, 2008), for certain Model A310 airplanes. On April 5, 2012, we issued AD 2012– 08–03, Amendment 39–17019 (77 FR 24367, April 24, 2012), for certain Model A300 B4–2C, B4–103, B4–203, B4–601, B4–603, B4–620, B4–622, B4– 605R, B4–622R, F4–605R, F4–622R, C4– 605R Variant F airplanes; and Model A310–203, –204, 221, –222, –304, –322, –324, and –325 airplanes. On July 23, 2012, we issued AD 2012– 15–14, Amendment 39–17143 (77 FR 46937, August 7, 2012), for certain Model A300 B4–2C, B4–103, B4–203, B4–601, B4–603, B4–620, B4–622, B4– 605R, B4–622R, F4–605R, and F4–622R, and C4–605R Variant F airplanes. AD 2008–17–02, Amendment 39– 15640 (73 FR 47032, August 13, 2008); AD 2012–08–03, Amendment 39–17019 (77 FR 24367, April 24, 2012); and AD 2012–15–14, Amendment 39–17143 (77 FR 46937, August 7, 2012); require actions intended to address an unsafe condition on the products listed above. Since we issued AD 2008–17–02, Amendment 39–15640 (73 FR 47032, August 13, 2008); AD 2012–08–03, Amendment 39–17019 (77 FR 24367, April 24, 2012); and AD 2012–15–14, Amendment 39–17143 (77 FR 46937, August 7, 2012); 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– 0176, dated September 7, 2012, corrected September 20, 2012 (referred to after this as the Mandatory Continuing Airworthiness Information, E:\FR\FM\12MRP1.SGM 12MRP1 Federal Register / Vol. 79, No. 48 / Wednesday, March 12, 2014 / Proposed Rules tkelley on DSK3SPTVN1PROD with PROPOSALS 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) Rib 5 aft fitting forward lug have been reported on A310 family aeroplanes. In some instances, corrosion pits caused the cracking of the forward lug. This condition, if not detected and corrected, may lead to the complete failure of the fitting and thus could affect the structural integrity of the MLG installation. EASA ADs 2006–0372R1 (http:// ad.easa.europa.eu/blob/easa_ad_2006_0372_ R1_superseeded.pdf/AD_2006-0372R1_1), 2007–0195 (http://ad.easa.europa.eu/blob/ easa_ad_2007_0195_superseded.pdf/AD_ 2007-0195_1) [which corresponds with FAA AD 2008–17–02, Amendment 39–15640 (73 FR 47032, August 13, 2008), 2010–0250 (http://ad.easa.europa.eu/blob/easa_ad_ 2010_0250_superseded.pdf/AD_2010-0250_ 1) [which corresponds with FAA AD 2012– 15–14, Amendment 39–17143 (77 FR 46937, August 7, 2012)] and 2010–0251 (http:// ad.easa.europa.eu/blob/easa_ad_2010_0251_ superseded.pdf/AD_2010-0251_1) [which corresponds with FAA AD 2012–08–03, Amendment 39–17019 (77 FR 24367, April 24, 2012)] were issued to address this condition and required a repetitive inspection programme of the MLG Rib 5 fitting forward lugs and, as terminating action, the embodiment of mandatory design change (bushes with increased interference fit). MLG Rib 5 forward lug on A320 family aeroplanes is a similar design to the A300/ A300–600/A310 family. Since those [EASA] ADs were issued, on two A321 aeroplanes, post modification (bushes with increased interference fit) MLG Rib 5 forward lugs were reportedly found ruptured. One other case was due to a sealant discrepancy that led to water ingress and consequently corrosion initiation, leading to cracking. Subsequent investigation results have shown that a remaining defect, not removed during the repair, had propagated, resulting in rupture of the lug. For the reasons stated above, this new [EASA] AD retains the requirements of EASA ADs 2006–0372R1, 2007–0195, 2010–0250 and 2010–0251, which are superseded, expands the applicability to all models and series of A300, A310, A300–600 and A300– 600ST aeroplanes, and requires: —for aeroplanes not yet modified or repaired, implementation of Modification Service Bulletin (SB) A300–57–0249, A310–57– 2090, A300–57–6106, or A300–57–9019, all at Revision 3, and —for aeroplanes which already embody that modifications, at original issue or revision 01 or 02 of the applicable SB, or have MLG Ribs already repaired in accordance with Airbus repair instruction R57240221 or R57249121, implementation of an additional inspection programme [repetitive detailed inspection for cracking or ultrasonic inspections for any crack indication] and associated corrective action(s) [detailed inspection for cracking if any crack indication found, and repair]. The unsafe condition is cracking of the forward lugs of the aft bearing at rib 5 VerDate Mar<15>2010 17:07 Mar 11, 2014 Jkt 232001 of the MLG on the LH and RH wings, which could affect the structural integrity of the MLG attachment, resulting in possible MLG collapse during landing or rollout. You may examine the MCAI in the AD docket on the Internet at http:// www.regulations.gov by searching for and locating it in Docket No. FAA– 2014–0142. Relevant Service Information Airbus has issued the following service information. • Airbus Alert Service Bulletin A300– 57A0248, dated December 12, 2006; • Airbus Service Bulletin A300–57– 0255, dated January 13, 2012; • Airbus Service Bulletin A300–57– 6112, dated January 13, 2012; • Airbus Service Bulletin A310–57– 2101, dated January 13, 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. 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 PO 00000 Frm 00016 Fmt 4702 Sfmt 4702 13939 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 specify 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 194 airplanes of U.S. registry. The actions that are required by AD 2008–17–02, Amendment 39–15640 (73 FR 47032, August 13, 2008), and retained in this proposed AD take about 5 work-hours per product, at an average labor rate of $85 per work-hour. Based on these figures, the estimated cost of the actions that were required by AD 2008–17–02 is $425 per product. The actions that are required by AD 2012–08–03, Amendment 39–17019 (77 FR 24367, April 24, 2012), and retained in this proposed AD take about 38 workhours per product, at an average labor rate of $85 per work-hour. Required parts cost about $4,590 per product. Based on these figures, the estimated cost of the actions that were required by AD 2012–08–03 is $7,820 per product. The actions that are required by AD 2012–15–14, Amendment 39–17143 (77 FR 46937, August 7, 2012), and retained in this proposed AD take about 3 workhours per product, at an average labor rate of $85 per work-hour. Based on these figures, the estimated cost of the actions that were required by AD 2012– 15–14 is $255 per product. We also estimate that it would take about 3 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $49,470, or $255 per product. E:\FR\FM\12MRP1.SGM 12MRP1 13940 Federal Register / Vol. 79, No. 48 / Wednesday, March 12, 2014 / Proposed Rules We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this proposed AD. We have no way of determining the number of products that may need these actions. According to the manufacturer, some of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. Paperwork Reduction Act A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB control number. The control number for the collection of information required by this AD is 2120–0056. The paperwork cost associated with this AD has been detailed in the Costs of Compliance section of this document and includes time for reviewing instructions, as well as completing and reviewing the collection of information. Therefore, all reporting associated with this AD is mandatory. Comments concerning the accuracy of this burden and suggestions for reducing the burden should be directed to the FAA at 800 Independence Ave. SW., Washington, DC 20591, ATTN: Information Collection Clearance Officer, AES–200. tkelley on DSK3SPTVN1PROD with PROPOSALS Authority for This Rulemaking 17:07 Mar 11, 2014 Jkt 232001 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 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. VerDate Mar<15>2010 Regulatory Findings We determined that this proposed AD would not have federalism implications under Executive Order 13132. This 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. [Amended] 2. The FAA amends § 39.13 by: a. Removing Airworthiness Directives (AD) 2008–17–02, Amendment 39– 15640 (73 FR 47032, August 13, 2008); AD 2012–08–03, Amendment 39–17019 (77 FR 24367, April 24, 2012); and AD 2012–15–14, Amendment 39–17143 (77 FR 46937, August 7, 2012); and ■ b. Adding the following new AD: ■ ■ Airbus: Docket No. FAA–2013–0142; Directorate Identifier 2012–NM–161–AD. (a) Comments Due Date We must receive comments by April 28, 2014.

(c) Applicability This AD applies to the Airbus airplanes identified in paragraphs (c)(1) and (c)(2) of this AD, certificated in any category, all manufacturer serial numbers. (1) Airbus Model A300 B2–1A, B2–1C, B2K–3C, and B2–203 airplanes; Model A300 B4–2C, B4–103, and B4–203 airplanes; Model A300 B4–601, B4–603, B4–620, B4–622, B4– 605R, B4–622R, F4–605R, and F4–622R airplanes; and Model A300 C4–605R Variant F airplanes. (2) Airbus Model A310–203, –204, –221, –222, –304, –322, –324, and –325 airplanes. (d) Subject Air Transport Association (ATA) of America Code 57, Wings. (e) Reason This AD was prompted by reports of cracking in the forward lug of the main landing gear (MLG) rib 5 aft bearing attachment. We are issuing this AD to detect and correct cracking of the forward lugs of the aft bearing at rib 5 of the MLG on the lefthand (LH) and right-hand (RH) wings, which could affect the structural integrity of the MLG attachment, resulting in possible MLG collapse during landing or rollout. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Retained Repetitive Detailed Inspection and Corrective Actions This paragraph restates the requirements of paragraph (f) of AD 2008–17–02, Amendment 39–15640 (73 FR 47032, August 13, 2008). For Model A310 airplanes, except for those where LH and RH wing MLG rib 5 forward lugs have been repaired by installation of oversized interference fit bushes as per Airbus A310 Repair Instruction R572–49121, or which have had Airbus Service Bulletin A310–57–2090 (Airbus Modification 13329) embodied in service: Do the actions specified in paragraphs (g)(1), (g)(2), and (g)(3) of this AD, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A310– 57A2088, dated November 6, 2006. (1) Before the accumulation of 12,000 total flight cycles, or within 14 days after February 6, 2007 (the effective date of AD 2007–02–09, Amendment 39–14896 (72 FR 2612, January 22, 2007)), whichever occurs later: Perform a detailed visual inspection of the LH and RH wing MLG rib 5 aft bearing forward lugs. (2) If any crack is detected at LH and/or RH aft bearing forward lug, contact Airbus and proceed with the replacement before next flight. (3) Repeat the inspection at intervals not exceeding 100 flight cycles. (h) Retained Actions and Compliance This paragraph restates the requirements of paragraph (g) of AD 2008–17–02, Amendment 39–15640 (73 FR 47032, August 13, 2008), with new service information for paragraphs (h)(2), (h)(3), and (h)(4)(ii) of this E:\FR\FM\12MRP1.SGM 12MRP1 tkelley on DSK3SPTVN1PROD with PROPOSALS Federal Register / Vol. 79, No. 48 / Wednesday, March 12, 2014 / Proposed Rules AD. For Model A310 airplanes, except for those where LH and RH wing MLG rib 5 forward lugs have been repaired by installation of oversized interference fit bushes as per Airbus A310 Repair Instruction R572–49121, or which have had Airbus Service Bulletin A310–57–2090 (Airbus Modification 13329) embodied in service: Before the accumulation of 12,000 total flight cycles or before the accumulation of 12,000 flight cycles on MLG rib 5, or within 14 days after September 17, 2008 (the effective date of AD 2008–17–02), whichever occurs latest, perform either a detailed visual inspection (DVI) or an ultrasonic inspection of the LH and RH MLG rib 5 aft bearing forward lug for cracks, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A310–57–2091, excluding Appendix 01, dated May 22, 2007. If a MLG rib 5 has been replaced on one side only, then the LH and RH must be considered separately. Doing this inspection ends the requirements of paragraph (g) for that MLG rib 5 only. Note 1 to paragraph (h) of this AD: The ultrasonic inspection will detect any crack at an early stage and will limit the risk of extensive repairs. This earlier crack detection is not possible with the DVI. (1) If no crack is detected during any inspection required by paragraph (h) of this AD: Repeat the applicable inspection at the time specified in paragraph (h)(1)(i) or (h)(1)(ii) of this AD. (i) Repeat the DVI thereafter at intervals not to exceed 100 flight cycles. (ii) Repeat the ultrasonic inspection thereafter at intervals not to exceed 825 flight cycles. (2) Replacement of the MLG rib 5 bushes with new bushes with high interference fit in the aft bearing forward lugs of MLG rib 5, in accordance with the Accomplishment Instructions of a service bulletin specified in paragraph (h)(2)(i), (h)(2)(ii), or (h)(2)(iii) of this AD, ends the repetitive inspections required by paragraph (h)(1) of this AD for that MLG rib 5 only. As of the effective date of this AD, use only Airbus Service Bulletin A310–57–2090, Revision 03, dated January 23, 2012, for the actions specified in this paragraph. (i) Airbus Service Bulletin A310–57–2090, Revision 01, dated December 19, 2007. (ii) Airbus Service Bulletin A310–57–2090, Revision 02, dated June 18, 2010. (iii) Airbus Service Bulletin A310–57– 2090, Revision 03, dated January 23, 2012. (3) If any crack is detected during the DVI required by paragraph (h) of this AD: Before further flight, contact Airbus for replacement instructions and replace the MLG rib 5 bushes before further flight.

AD 95–24– 04 requires repetitive inspections to detect cracks at the aft spar web of the wings, and repair if necessary. Since we issued AD 95–24–04, we have determined that the inspection threshold and interval must be reduced to allow timely detection of cracks and accomplishment of applicable repairs, because of cracking in the rear spar web of the wings between certain ribs due to fatigue-related high shear stress. This proposed AD would reduce the inspection compliance time and interval, and would expand the applicability to airplanes on which a certain Airbus modification has been embodied in production and to airplanes on which a certain Airbus service bulletin has been embodied in service. We are proposing this AD to detect and correct fatigue-related cracking, which could result in reduced structural integrity of the wing.

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2008-17-
02, AD 2012-08-03, and AD 2012-15-14, for certain Airbus Model A300 B4-
2C, B4-103, and B4-203 airplanes; Model A300 B4-600, B4-600R, and F4-
600R series airplanes, and Model C4-605R Variant F airplanes 
(collectively called A300-600 series airplanes); and Model A310 series 
airplanes. AD 2008-17-02, AD 2012-08-03, and AD 2012-15-14 currently 
require repetitive inspections of the forward lugs of the aft bearing 
at rib 5 of the main landing gear (MLG) on the left-hand (LH) and 
right-hand (RH) wings, and repair if necessary; and installation of new 
bushes with increased interference fit in the forward lug of the aft 
bearing at rib 5 of the MLG on the LH and RH wings. Since we issued AD 
2008-17-02, AD 2012-08-03, and AD 2012-15-14, we have received two 
reports of ruptured MLG rib 5 forward lugs that had been modified 
(bushes with increased interference fit). This proposed AD would add 
airplanes to the applicability; and would add, for certain airplanes, 
repetitive inspections of the MLG rib 5 aft bearing forward lugs, and 
repair if necessary. We are proposing this AD to detect and correct 
cracking of the forward lugs of the aft bearing at rib 5 of the MLG on 
the LH and RH wings, which could affect the structural integrity of the 
MLG attachment, resulting in possible MLG collapse during landing or 
rollout.

DATES: We must receive comments on this proposed AD by April 28, 2014.

Discussion

    On July 31, 2008, we issued AD 2008-17-02, Amendment 39-15640 (73 
FR 47032, August 13, 2008), for certain Model A310 airplanes.
    On April 5, 2012, we issued AD 2012-08-03, Amendment 39-17019 (77 
FR 24367, April 24, 2012), for certain Model A300 B4-2C, B4-103, B4-
203, B4-601, B4-603, B4-620, B4-622, B4-605R, B4-622R, F4-605R, F4-
622R, C4-605R Variant F airplanes; and Model A310-203, -204, 221, -222, 
-304, -322, -324, and -325 airplanes.
    On July 23, 2012, we issued AD 2012-15-14, Amendment 39-17143 (77 
FR 46937, August 7, 2012), for certain Model A300 B4-2C, B4-103, B4-
203, B4-601, B4-603, B4-620, B4-622, B4-605R, B4-622R, F4-605R, and F4-
622R, and C4-605R Variant F airplanes.
    AD 2008-17-02, Amendment 39-15640 (73 FR 47032, August 13, 2008); 
AD 2012-08-03, Amendment 39-17019 (77 FR 24367, April 24, 2012); and AD 
2012-15-14, Amendment 39-17143 (77 FR 46937, August 7, 2012); require 
actions intended to address an unsafe condition on the products listed 
above.
    Since we issued AD 2008-17-02, Amendment 39-15640 (73 FR 47032, 
August 13, 2008); AD 2012-08-03, Amendment 39-17019 (77 FR 24367, April 
24, 2012); and AD 2012-15-14, Amendment 39-17143 (77 FR 46937, August 
7, 2012); the European Aviation Safety Agency (EASA), which is the 
Technical Agent for the Member States of the European Community, has 
issued EASA Airworthiness Directive 2012-0176, dated September 7, 2012, 
corrected September 20, 2012 (referred to after this as the Mandatory 
Continuing Airworthiness Information,

[[Page 13939]]

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) Rib 5 
aft fitting forward lug have been reported on A310 family 
aeroplanes. In some instances, corrosion pits caused the cracking of 
the forward lug.
    This condition, if not detected and corrected, may lead to the 
complete failure of the fitting and thus could affect the structural 
integrity of the MLG installation.
    EASA ADs 2006-0372R1 (http://ad.easa.europa.eu/blob/easa_ad_2006_0372_R1_superseeded.pdf/AD_2006-0372R1_1), 2007-0195 
(http://ad.easa.europa.eu/blob/easa_ad_2007_0195_superseded.pdf/AD_2007-0195_1) [which corresponds with FAA AD 2008-17-02, 
Amendment 39-15640 (73 FR 47032, August 13, 2008), 2010-0250 (http://ad.easa.europa.eu/blob/easa_ad_2010_0250_superseded.pdf/AD_2010-0250_1) [which corresponds with FAA AD 2012-15-14, Amendment 
39-17143 (77 FR 46937, August 7, 2012)] and 2010-0251 (http://ad.easa.europa.eu/blob/easa_ad_2010_0251_superseded.pdf/AD_2010-0251_1) [which corresponds with FAA AD 2012-08-03, Amendment 
39-17019 (77 FR 24367, April 24, 2012)] were issued to address this 
condition and required a repetitive inspection programme of the MLG 
Rib 5 fitting forward lugs and, as terminating action, the 
embodiment of mandatory design change (bushes with increased 
interference fit).
    MLG Rib 5 forward lug on A320 family aeroplanes is a similar 
design to the A300/A300-600/A310 family. Since those [EASA] ADs were 
issued, on two A321 aeroplanes, post modification (bushes with 
increased interference fit) MLG Rib 5 forward lugs were reportedly 
found ruptured.
    One other case was due to a sealant discrepancy that led to 
water ingress and consequently corrosion initiation, leading to 
cracking. Subsequent investigation results have shown that a 
remaining defect, not removed during the repair, had propagated, 
resulting in rupture of the lug.
    For the reasons stated above, this new [EASA] AD retains the 
requirements of EASA ADs 2006-0372R1, 2007-0195, 2010-0250 and 2010-
0251, which are superseded, expands the applicability to all models 
and series of A300, A310, A300-600 and A300-600ST aeroplanes, and 
requires:

--for aeroplanes not yet modified or repaired, implementation of 
Modification Service Bulletin (SB) A300-57-0249, A310-57-2090, A300-
57-6106, or A300-57-9019, all at Revision 3, and
--for aeroplanes which already embody that modifications, at 
original issue or revision 01 or 02 of the applicable SB, or have 
MLG Ribs already repaired in accordance with Airbus repair 
instruction R57240221 or R57249121, implementation of an additional 
inspection programme [repetitive detailed inspection for cracking or 
ultrasonic inspections for any crack indication] and associated 
corrective action(s) [detailed inspection for cracking if any crack 
indication found, and repair].

The unsafe condition is cracking of the forward lugs of the aft bearing 
at rib 5 of the MLG on the LH and RH wings, which could affect the 
structural integrity of the MLG attachment, resulting in possible MLG 
collapse during landing or rollout. You may examine the MCAI in the AD 
docket on the Internet at http://www.regulations.gov by searching for 
and locating it in Docket No. FAA-2014-0142.

Relevant Service Information

    Airbus has issued the following service information.
     Airbus Alert Service Bulletin A300-57A0248, dated December 
12, 2006;
     Airbus Service Bulletin A300-57-0255, dated January 13, 
2012;
     Airbus Service Bulletin A300-57-6112, dated January 13, 
2012;
     Airbus Service Bulletin A310-57-2101, dated January 13, 
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.
    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 specify 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 194 airplanes of U.S. 
registry.
    The actions that are required by AD 2008-17-02, Amendment 39-15640 
(73 FR 47032, August 13, 2008), and retained in this proposed AD take 
about 5 work-hours per product, at an average labor rate of $85 per 
work-hour. Based on these figures, the estimated cost of the actions 
that were required by AD 2008-17-02 is $425 per product.
    The actions that are required by AD 2012-08-03, Amendment 39-17019 
(77 FR 24367, April 24, 2012), and retained in this proposed AD take 
about 38 work-hours per product, at an average labor rate of $85 per 
work-hour. Required parts cost about $4,590 per product. Based on these 
figures, the estimated cost of the actions that were required by AD 
2012-08-03 is $7,820 per product.
    The actions that are required by AD 2012-15-14, Amendment 39-17143 
(77 FR 46937, August 7, 2012), and retained in this proposed AD take 
about 3 work-hours per product, at an average labor rate of $85 per 
work-hour. Based on these figures, the estimated cost of the actions 
that were required by AD 2012-15-14 is $255 per product.
    We also estimate that it would take about 3 work-hours per product 
to comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Based on these figures, we estimate 
the cost of this proposed AD on U.S. operators to be $49,470, or $255 
per product.

[[Page 13940]]

    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this proposed 
AD. We have no way of determining the number of products that may need 
these actions.
    According to the manufacturer, some of the costs of this proposed 
AD may be covered under warranty, thereby reducing the cost impact on 
affected individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB control number. The control 
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in 
the Costs of Compliance section of this document and includes time for 
reviewing instructions, as well as completing and reviewing the 
collection of information. Therefore, all reporting associated with 
this AD is mandatory. Comments concerning the accuracy of this burden 
and suggestions for reducing the burden should be directed to the FAA 
at 800 Independence Ave. SW., Washington, DC 20591, ATTN: Information 
Collection Clearance Officer, AES-200.

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 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
