ACTION: Interim final rule; correction. AGENCY: The U.S. Small Business Administration (SBA) is correcting an interim final rule that appeared in the Federal Register on August 20, 2012 (75 FR 49991), effective October 1, 2012. The interim rule amended SBA’s Small Business Size Regulations by incorporating the Office of Management and Budget’s 2012 North American Industry Classification System update (NAICS 2012) into its table of small business size standards. The NAICS 2012 revised the definitions of some NAICS industries by deleting some and merging others with the new or other revised industries. This action corrects the small business size standard for NAICS 334419, Other Electronic Component Manufacturing, from 500 employees to 750 employees, effective immediately. DATES: Effective December 2, 2014. FOR FURTHER INFORMATION CONTACT: Khem Sharma, Chief, Office of Size SUMMARY: Standards, U.S. Small Business Administration, 409 Third Street SW., Washington, DC 20416. SUPPLEMENTARY INFORMATION: The NAICS 2012 revised the NAICS 2007 definition for NAICS 334419, Other Electronic Component Manufacturing, by merging with it NAICS 334411, Electron Tube Manufacturing, but retained the existing industry title. NAICS 334419 had a size standard of 500 employees, while NAICS 334411 had 750 employees. In accordance with SBA’s policy of adopting the highest size standard among the industries merged, on page 50001 of the August 20, 2012 interim final rule (75 FR 49991), SBA indicated in Table 2 ‘‘NAICS 2012 Codes Matched to NAICS 2007 Codes and Size Standards’’ that it is adopting 750 employees as the small business size standard for the revised NAICS 334419. To amend the table in § 121.201, ‘‘Small Business Size Standards by NAICS Industry’’, on page 50008, the rule states ‘‘ttt. Remove the entries for 334411, 334414, and 334415’’. However, the rule did not revise the size standard for NAICS 344119 to 750 employees. Therefore, the revised table, ‘‘Small Business Size Standards by NAICS Industry’’ shows the old, incorrect size standard of 500 employees for NAICS 334419. Need For Correction The purpose of this action is to correct the table ‘‘Small Business Size Standards by NAICS Industry’’ (13 CFR 121.201) by revising the size standard for NAICS 334419, Other Electronic Component Manufacturing, from 500 employees to 750 employees. List of Subjects in 13 CFR Part 121 Administrative practice and procedure, Government procurement, Government property, Grant programs— business, Individuals with disabilities, Loan programs—business, Reporting and recordkeeping requirements, Small businesses. For the reasons set forth in the preamble, SBA amends 13 CFR part 121 by making the following correcting amendment: PART 121—SMALL BUSINESS SIZE REGULATIONS 1. The authority citation for part 121 continues to read as follows: ■ Authority: 15 U.S.C. 632, 634(b)(6), 636(b), 662, 694a(9). 2. In § 121.201, revise the entry ‘‘334419’’ in the table, ‘‘Small Business Size Standards by NAICS Industry’’ to read as follows: ■ § 121.201 What size standards has SBA identified by North American Industry Classification System codes? * * * * * SMALL BUSINESS SIZE STANDARDS BY NAICS INDUSTRY NAICS codes NAICS U.S. industry title Size standards in millions of dollars * * 334419 ............................................. * * * Other Electronic Component Manufacturing ............................................. * ........................ * * * * * * Dated: November 18, 2014.

SUPPLEMENTARY INFORMATION: VerDate Sep<11>2014 16:18 Dec 01, 2014 Jkt 235001 Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2008–17–03, Amendment 39–15641 (73 FR 48288, August 19, 2008). AD 2008–17–03 applied to certain The Boeing Company Model 737–100, –200, –200C, –300, –400, and –500 series airplanes. The NPRM published in the Federal Register on April 14, 2014 (79 FR 20824). The NPRM was prompted by reports of cracks found at the cutout in the web of body station frame 303.9 inboard of stringer 16L, and the subsequent determination that additional airplanes are subject to the requirements of AD 2008–17–03. The NPRM proposed to continue to require repetitive inspections for fuselage frame cracking and applicable corrective action, add airplanes to the applicability, and to provide optional terminating action (repair/preventive change) for the repetitive inspections for the airplanes subject to AD 2008–17–03. We are issuing this AD to detect and correct fuselage frame cracking, which could prevent the left forward entry door from sealing correctly, and could cause in-flight decompression of the airplane. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM (79 FR 20824, April 14, 2014) and the FAA’s response to each comment. Effect of Winglets on This AD Aviation Partners Boeing stated that accomplishing the supplemental type certificate (STC) ST01219SE (https:// rgl.faa.gov/Regulatory_and_Guidance_ Library/rgstc.nsf/0/ ebd1cec7b301293e86257cb30045557a/ $FILE/ST01219SE.pdf) does not affect the actions specified in the NPRM (79 FR 20824, April 14, 2014). We concur with the commenter. We have redesignated paragraphs (c), (c)(1), and (c)(2) of the NPRM (79 FR 20824, April 14, 2014) as paragraphs (c)(1), (c)(1)(i), and (c)(1)(ii) of this AD, and added new paragraph (c)(2) to this AD to state that installation of STC ST01219SE (https://rgl.faa.gov/ Regulatory_and_Guidance_Library/ rgstc.nsf/0/ ebd1cec7b301293e86257cb30045557a/ $FILE/ST01219SE.pdf) does not affect the ability to accomplish the actions required by this AD. Therefore, for airplanes on which STC ST01219SE is PO 00000 Frm 00003 Fmt 4700 Sfmt 4700 71297 installed, a ‘‘change in product’’ alternative method of compliance (AMOC) approval request is not necessary to comply with the requirements of 14 CFR 39.17. Request To Clarify Certain Requirements All Nippon Airways (ANA) requested that we revise paragraph (i) of the proposed AD (79 FR 20824, April 14, 2014), which added new inspections for Group 2 airplanes in accordance with Boeing Alert Service Bulletin 737– 53A1188, Revision 3, dated September 6, 2013. ANA claimed that this requirement included unnecessary procedures for opening and closing access from the aft side of the inspection area because the inspection is required from the forward side. ANA suggested that we include the information in Note 8 of paragraph 3.A., General Instructions, of Boeing Alert Service Bulletin 737–53A1188, Revision 3, dated September 6, 2013, to exclude the unnecessary procedures. Note 8 states, in part, as follows: If it is necessary to remove more parts for access, you can remove those parts. If you can get access without removing identified parts, it is not necessary to remove all of the identified parts. . . . We agree with the request. We have revised paragraph (i) in this AD to point to this exception in new paragraph (j)(4) in this AD. We have similarly changed paragraphs (g) and (h) in this AD to also specify this exception. Conclusion We reviewed the relevant data, considered 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 minor changes: • Are consistent with the intent that was proposed in the NPRM (73 FR 20824, April 14, 2014) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (73 FR 20824, April 14, 2014). We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD. Costs of Compliance We estimate that this AD affects 148 airplanes of U.S. registry. We estimate the following costs to comply with this AD: E:\FR\FM\02DER1.SGM 02DER1 71298 Federal Register / Vol. 79, No. 231 / Tuesday, December 2, 2014 / Rules and Regulations ESTIMATED COSTS: REQUIRED ACTIONS Action Labor cost Inspection ...................... 31 to 33 work-hours × $85 per hour = up to $2,805 per inspection cycle. Cost per product Parts cost $0 Up to $2,805 per inspection cycle. Cost on U.S. operators Up to $415,140 per inspection cycle ESTIMATED COSTS: OPTIONAL MODIFICATION Action Labor cost Parts cost Repair/preventive change ...................... 12 to 30 work-hours × $85 per hour = up to $2,550. $564 to $2,236 .............. under the criteria of the Regulatory Flexibility Act. 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. mstockstill on DSK4VPTVN1PROD with RULES Regulatory Findings We have 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 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 VerDate Sep<11>2014 16:18 Dec 01, 2014 Jkt 235001 List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1.

FOR FURTHER INFORMATION CONTACT: We are revising airworthiness directive (AD) 2010–17–11R1, which applies to all Dowty Propellers R408/6– 123–F/17 model propellers. AD 2010– 17–11R1 required initial application of sealant between the bus bar assembly and the backplate assembly of certain line-replaceable units (LRUs) and repetitive re-applications of sealant on all R408/6–123–F/17 model propellers. AD 2010–17–11R1 also provided an optional terminating action to the repetitive re-application of sealant. This AD increases the interval allowed between the required re-application of sealant, and specifies an additional acceptable sealant. This AD was prompted by failure of the propeller deice bus bar due to friction or contact between the bus bar and the backplate assembly, consequent intermittent short circuit, and possible double generator failure. We are issuing this AD to prevent an in-flight double generator failure, which could result in reduced control of the airplane. DATES: This AD is effective January 6, 2015.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to revise AD 2010–17–11R1, Amendment 39–17481 (78 FR 41283, July 10, 2013), (‘‘AD 2010–17–11R1’’). AD 2010–17–11R1 applied to the specified products. The NPRM published in the Federal Register on March 19, 2014 (79 FR 15269). The NPRM proposed to require increasing the interval allowed between the required re-application of sealant and specified an additional acceptable sealant. Comments We gave the public the opportunity to participate in developing this AD. We considered the comments received. PO 00000 Frm 00006 Fmt 4700 Sfmt 4700 Request Correction to the Applicability and Compliance Paragraphs Horizon Air requested a correction in the Applicability and Compliance paragraphs for possible typographical errors between AD 2010–17–11R1 and the NPRM (79 FR 15269, March 19, 2014). Horizon Air stated that the Applicability has changed from ‘‘. . . serial number (S/N) below DAP0327’’ in AD 2010–17–11R1 to ‘‘. . . S/N below DAP0927’’ in the proposed rule. With no discussion about the increased number of affected propellers, Horizon Air believes that typographical errors exist in the Applicability and Compliance sections. We do not agree. AD 2010–17–11R1 required initial sealant application to all Dowty Propellers R408/6–123–F/17 model propellers with a hub, actuator, and backplate assembly LRU S/Ns below DAP0347, not DAP0327 as quoted above. AD 2010–17–11R1 also required repetitive re-application of sealant for all LRU S/Ns below DAP0927. We did not change this AD. Request Change to Optional Terminating Action Horizon Air requested that all revisions to Dowty Propellers Service Bulletin (SB) No. D8400–61–94 be included in the Optional Terminating Action paragraph. The implied reason for this request was to support terminating action throughout the range of qualified SBs. We partially agree. We agree that Dowty Propellers SB No. D8400–61–94, Revision 6, dated December 12, 2013 and earlier revisions provide adequate corrective actions to address the unsafe condition. We changed the Optional Terminating Action paragraph to include Dowty Propellers SB No. D8400–61–94, Revision 6, dated December 12, 2013 and earlier revisions. We do not agree that unknown future SB versions should be included in this AD. The content of future SB revisions is speculation. We did not change this AD to include all revisions of the SB. Request for Alternative Method of Compliance Horizon Air requested that we allow the use of 3M 4200 sealant as an equivalent replacement for the 3M 5300 sealant. We agree. We approved 3M 4200 as an acceptable sealant in response to the Horizon Air comment to AD 2010–17– 11R1 when that AD was at the NPRM stage; see 78 FR 41283, July 10, 2013. 3M 4200 sealant is also one of three sealants identified in Dowty Propellers Alert Service Bulletin (ASB) No. D8400– E:\FR\FM\02DER1.SGM 02DER1

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2008-17-03 for 
certain The Boeing Company Model 737-100, -200, -200C, -300, -400, and 
-500 series airplanes. AD 2008-17-03 required repetitive inspections to 
detect fuselage frame cracking, and corrective action if necessary. AD 
2008-17-03 also provided for optional terminating action (repair/
preventive change) for the repetitive inspections. This new AD adds 
airplanes to the applicability, but does not provide terminating action 
for the newly added airplanes. This AD was prompted by reports of 
cracks found at the cutout in the web of body station

frame 303.9 inboard of stringer 16L, as well as a new report of 
cracking found on an airplane not identified in the applicability of AD 
2008-17-03. We are issuing this AD to detect and correct fuselage frame 
cracking, which could prevent the left forward entry door from sealing 
correctly, and could cause in-flight decompression of the airplane.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2008-17-03, Amendment 39-15641 (73 FR 48288, 
August 19, 2008). AD 2008-17-03 applied to certain The Boeing Company 
Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. The 
NPRM published in the Federal Register on April 14, 2014 (79 FR 20824). 
The NPRM was prompted by reports of cracks found at the cutout in the 
web of body station frame 303.9 inboard of stringer 16L, and the 
subsequent determination that additional airplanes are subject to the 
requirements of AD 2008-17-03. The NPRM proposed to continue to require 
repetitive inspections for fuselage frame cracking and applicable 
corrective action, add airplanes to the applicability, and to provide 
optional terminating action (repair/preventive change) for the 
repetitive inspections for the airplanes subject to AD 2008-17-03. We 
are issuing this AD to detect and correct fuselage frame cracking, 
which could prevent the left forward entry door from sealing correctly, 
and could cause in-flight decompression of the airplane.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM (79 
FR 20824, April 14, 2014) and the FAA's response to each comment.

Effect of Winglets on This AD

    Aviation Partners Boeing stated that accomplishing the supplemental 
type certificate (STC) ST01219SE (https://rgl.faa.gov/
Regulatory_and_Guidance_Library/rgstc.nsf/0/
ebd1cec7b301293e86257cb30045557a/$FILE/ST01219SE.pdf) does not affect 
the actions specified in the NPRM (79 FR 20824, April 14, 2014).
    We concur with the commenter. We have redesignated paragraphs (c), 
(c)(1), and (c)(2) of the NPRM (79 FR 20824, April 14, 2014) as 
paragraphs (c)(1), (c)(1)(i), and (c)(1)(ii) of this AD, and added new 
paragraph (c)(2) to this AD to state that installation of STC ST01219SE 
(https://rgl.faa.gov/Regulatory_and_Guidance_Library/rgstc.nsf/0/
ebd1cec7b301293e86257cb30045557a/$FILE/ST01219SE.pdf) does not affect 
the ability to accomplish the actions required by this AD. Therefore, 
for airplanes on which STC ST01219SE is installed, a ``change in 
product'' alternative method of compliance (AMOC) approval request is 
not necessary to comply with the requirements of 14 CFR 39.17.

Request To Clarify Certain Requirements

    All Nippon Airways (ANA) requested that we revise paragraph (i) of 
the proposed AD (79 FR 20824, April 14, 2014), which added new 
inspections for Group 2 airplanes in accordance with Boeing Alert 
Service Bulletin 737-53A1188, Revision 3, dated September 6, 2013. ANA 
claimed that this requirement included unnecessary procedures for 
opening and closing access from the aft side of the inspection area 
because the inspection is required from the forward side. ANA suggested 
that we include the information in Note 8 of paragraph 3.A., General 
Instructions, of Boeing Alert Service Bulletin 737-53A1188, Revision 3, 
dated September 6, 2013, to exclude the unnecessary procedures. Note 8 
states, in part, as follows:

If it is necessary to remove more parts for access, you can remove 
those parts. If you can get access without removing identified 
parts, it is not necessary to remove all of the identified parts. . 
. .

    We agree with the request. We have revised paragraph (i) in this AD 
to point to this exception in new paragraph (j)(4) in this AD. We have 
similarly changed paragraphs (g) and (h) in this AD to also specify 
this exception.

Conclusion

    We reviewed the relevant data, considered 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 minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (73 FR 20824, April 14, 2014) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (73 FR 20824, April 14, 2014).
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Costs of Compliance

    We estimate that this AD affects 148 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

    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 have 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 DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

List of Subjects in 14 CFR Part 39

Adoption of the Amendment

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

PART 39--AIRWORTHINESS DIRECTIVES

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

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


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by removing Airworthiness Directive (AD) 
2008-17-03, Amendment 39-15641 (73 FR 48288, August 19, 2008), and 
adding the following new AD:

2014-23-10 The Boeing Company: Amendment 39-18026; Docket No. FAA-
2014-0195; Directorate Identifier 2013-NM-195-AD.

(a) Effective Date

    This AD is effective January 6, 2015.

(b) Affected ADs

    This AD replaces AD 2008-17-03, Amendment 39-15641 (73 FR 48288, 
August 19, 2008).

(c) Applicability

    (1) This AD applies to The Boeing Company airplanes, 
certificated in any category, identified in paragraphs (c)(1)(i) and 
(c)(1)(ii) of this AD.
    (i) Model 737-100, -200, -200C, -300, -400, and -500 series 
airplanes, as identified in Boeing Alert Service Bulletin 737-
53A1197, dated August 25, 2006.
    (ii) Model 737-300, -400, and -500 series airplanes, as 
identified in Boeing Alert Service Bulletin 737-53A1188, Revision 3, 
dated September 6, 2013.
    (2) Installation of Supplemental Type Certificate (STC) 
ST01219SE (https://rgl.faa.gov/Regulatory_and_Guidance_Library/
rgstc.nsf/0/ebd1cec7b301293e86257cb30045557a/$FILE/ST01219SE.pdf) 
does not affect the ability to accomplish the actions required by 
this AD. For airplanes on which STC ST01219SE (https://rgl.faa.gov/
Regulatory_and_Guidance_Library/rgstc.nsf/0/
ebd1cec7b301293e86257cb30045557a/$FILE/ST01219SE.pdf) is installed, 
therefore, a ``change in product'' alternative method of compliance 
(AMOC) approval request is not necessary to comply with the 
requirements of 14 CFR 39.17.

(d) Subject

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

(e) Unsafe Condition

    This AD was prompted by reports of cracks found at the cutout in 
the web of body station frame 303.9 inboard of stringer 16L, and a 
new report of cracking found on an airplane not included in the 
applicability of AD 2008-17-03, Amendment 39-15641 (73 FR 48288, 
August 19, 2008). We are issuing this AD to detect and correct such 
cracking, which could prevent the left forward entry door from 
sealing correctly, and could cause in-flight decompression of the 
airplane.

(f) Compliance

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

(g) Retained Repetitive Inspections: Group 1 Airplanes, Boeing Alert 
Service Bulletin 737-53A1188, Revision 2, Dated May 9, 2007; or Boeing 
Alert Service Bulletin 737-53A1188, Revision 3, Dated September 6, 2013

    This paragraph restates the requirements of paragraph (f) of AD 
2008-17-03, Amendment 39-15641 (73 FR 48288, August 19, 2008), with 
revised service information and airplane groupings. For airplanes 
identified as Group 1 in Boeing Alert Service Bulletin 737-53A1188, 
Revision 3, dated September 6, 2013: Do detailed and high frequency 
eddy current (HFEC) inspections in the web and doubler around the 
slotted holes in the frame web at stringers 15L and 16L, in 
accordance with the Accomplishment Instructions of Boeing Alert 
Service Bulletin 737-53A1188, Revision 2, dated May 9, 2007; or 
Boeing Alert Service Bulletin 737-53A1188, Revision 3, dated 
September 6, 2013, except as provided by paragraph (j)(4) of this 
AD. Do

[[Page 71299]]

the inspections at the applicable time specified in paragraph 1.E., 
``Compliance,'' of Boeing Alert Service Bulletin 737-53A1188, 
Revision 3, dated September 6, 2013. Do all applicable corrective 
actions before further flight in accordance with Boeing Alert 
Service Bulletin 737-53A1188, Revision 2, dated May 9, 2007; or 
Boeing Alert Service Bulletin 737-53A1188, Revision 3, dated 
September 6, 2013; except as provided by paragraph (j)(3) of this 
AD. Repeat the inspections at intervals not to exceed 4,500 flight 
cycles, until accomplishment of the repair/preventive change in 
accordance with Boeing Alert Service Bulletin 737-53A1188, Revision 
2, dated May 9, 2007; or Boeing Alert Service Bulletin 737-53A1188, 
Revision 3, dated September 6, 2013; which terminates the repetitive 
inspection requirements for the airplanes identified in this 
paragraph. A repair/preventive change done using Boeing Alert 
Service Bulletin 737-53A1188, dated April 9, 1998; or Boeing Alert 
Service Bulletin 737-53A1188, Revision 1, dated March 18, 1999; does 
not terminate the repetitive inspections, but the repetitive 
inspections may be terminated after the existing kit is replaced 
with a new kit in accordance with paragraph 3.B., Part II, step 3, 
or Part III, step 3, of Boeing Alert Service Bulletin 737-53A1188, 
Revision 2, dated May 9, 2007. As of the effective date of this AD, 
only Boeing Alert Service Bulletin 737-53A1188, Revision 3, dated 
September 6, 2013, may be used to do the actions required by this 
paragraph.
