FAA-2016-5468; Directorate Identifier 2015-NM-021-AD; Amendment 39-18806; AD 2017-04-11] RIN 2120-AA64 Airworthiness Directives; The Boeing Company Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Final rule. SUMMARY: We are adopting a new airworthiness directive

(AD)all The Boeing Company Model 737-600, -700, -700C, -800, and -900 series airplanes. This AD was prompted by reports of paint deterioration on the surface of the main landing gear

(MLG)and the early onset of corrosion in the trunnion bore of the MLG outer cylinder. This AD requires identifying affected parts, repetitive external surface detailed inspections for damage of affected parts, and related investigative and corrective actions if necessary. For certain airplanes, this AD also requires a detailed inspection and bushing replacement of the trunnion bore, and related investigative and corrective actions if necessary. We are issuing this AD to address the unsafe condition on these products. DATES: This AD is effective March 29, 2017. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of March 29, 2017.

(NPRM)to amend 14 CFR part 39 by adding an AD that would apply to all The Boeing Company Model 737-600, -700, -700C, -800, and -900 series airplanes. The NPRM published in the **Federal Register** on April 12, 2016 (81 FR 21497) (“the NPRM”). The NPRM was prompted by reports of paint deterioration on the surface of the MLG and the early onset of corrosion in the trunnion bore of the MLG outer cylinder. The NPRM proposed to require identifying affected parts, repetitive external surface detailed inspections for damage of affected parts, and related investigative and corrective actions, if necessary. For certain airplanes, the NPRM also proposed to require a detailed inspection and bushing replacement of the trunnion bore, and related investigative and corrective actions, if necessary. We are issuing this AD to prevent stress corrosion cracking of the external surfaces of the MLG, which could result in a fracture of the MLG and consequent MLG collapse. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM and the FAA's response to each comment. Request To Withdraw the NPRM Messier Services Asia Pte Ltd (MS Asia) explained that this maintenance, repair, and overhaul

(MRO)facility, located in Singapore, has disclosed to Boeing that between November 2007 and December 2011, painting performed by MS Asia on certain landing gear legs as part of its overhaul service for Boeing did not fully conform to Boeing instructions and specifications. MS Asia stated that this painting error was disclosed to Boeing for Model 737 airplane landing gears identified in Boeing Special Attention Service Bulletin 737-32-1486, dated November 6, 2014, as revised by Boeing Special Attention Service Bulletin 737-32-1486, Revision 1, dated April 1, 2015 (“SASB 737-32-1486, R1”). MS Asia refuted and continues to refute that the painting has generated the potential onset of corrosion discovered on the MLG. MS Asia explained that it had the opportunity to demonstrate to Boeing the absence of links between these two events and is willing to reiterate its technical demonstration to the FAA. MS Asia asserted that the NPRM makes an incorrect statement and conclusion, and is without technical evidence that the root cause of the corrosion detected on the trunnion bore and the associated risk of fracture is the consequence of the incorrect paint scheme application. MS Asia also stated that the NPRM is creating confusion when it refers to SAFRAN Messier-Bugatti-Dowty, and that the painting issues only affect gears overhauled by MS Asia during the period of November 2007 to December 2011. MS Asia asserted that no painting issues have affected landing gears overhauled by the MRO entity of Messier-Bugatti-Dowty outside the period of November 2007 to December 2011. From these statements, we infer that MS Asia is requesting we withdraw the NPRM. We do not agree. Landing gear components include materials that are very sensitive to corrosion and cracking and are not tolerant of improper maintenance. In particular, high strength steel, once corroded, can readily develop cracks which could then propagate very rapidly and render inspection programs ineffectual. This is why it is imperative that protective finishes be applied as specified. The determination of a connection between improper finish application and the potential onset of corrosion was made by Boeing in Boeing Special Attention Service Bulletin 737-32-1486, dated November 6, 2014, with review and concurrence by the FAA. This connection has also been validated by extensive fleet experience. MS Asia provided no definitive data to substantiate its statement that there is not such a connection between its painting (application of unqualified primer) and corrosion. It should also be noted that this painting was only one of several discrepancies noted that indicated improper maintenance. There is no refutation of the finding that the components were not overhauled in accordance with Boeing instructions and specifications. These instructions and specifications, or their equivalent, are in turn included in operators' maintenance programs that are approved by the governing regulatory authority. We are willing to review data MS Asia might wish to submit regarding this AD. However, this issue has been determined to be a safety issue by both Boeing and the FAA, and the FAA has also determined that it is not appropriate to withdraw the NPRM. If a future review of submitted data substantiates MS Asia's claim that the root cause of the corrosion detected on the trunnion bore and the associated risk of fracture is not the consequence of the incorrect paint scheme application, then we may grant relief through either additional rulemaking or a global alternative method of compliance (AMOC). We have not revised this final rule regarding a connection between improper finish application and the potential onset of corrosion. We note that the dates of the discrepant overhaul specified in paragraph

(g)of this AD differ from the dates given in Boeing Special Attention Service Bulletin 737-32-1486, dated November 6, 2014, and in MS Asia's comments. The dates in paragraph

(g)of this AD were determined by an investigation of MS Asia's maintenance records by an FAA inspector. After that review of maintenance records by an FAA field office, we concur with MS Asia's statement that this improper rework is limited to their facility in Singapore. We have revised this final rule to refer to MS Asia instead of SAFRAN Messier-Bugatti-Dowty to avoid confusion regarding affected parts. Requests for Clarification Regarding the Nose Landing Gear

(NLG)Boeing and the European Aviation Safety Agency

(EASA)requested that we clarify why the NPRM did not address actions specified in the service information for the NLG. We agree that there is a need to clarify. The discrepant rework described in the Boeing service information does specify the NLG as well as the MLG. We note that in the Boeing service information, inspections of the MLG were specified for safety and were so labeled. However, inspections of the NLG were not determined by Boeing to be a safety issue. Those NLG inspections were labeled as economic inspections. This determination is consistent with the FAA's safety determination. Issues involving potential collapse of the NLG are evaluated on a case-by-case basis, but are typically determined not to be safety issues. In the event of failure of the NLG, the flight crew normally retains adequate directional control of the airplane via differential braking, engine thrust, and/or rudder. This is not the case for MLG collapses. We have not changed this AD in this regard. Request To Revise Corrective Action in Paragraph

(i)of the Proposed AD Boeing requested that we include Part 7 of the Accomplishment Instructions of Boeing Special Attention Service Bulletin 737-32-1486, dated November 6, 2014, in the applicable investigative and corrective actions identified in paragraph

(i)of the proposed AD. Boeing stated that the replacement of the MLG outer cylinder in accordance with Part 7 should be allowed as an option for compliance with the requirements of paragraph

(i)of the proposed AD. We have confirmed that Boeing's requested change to paragraph

(i)of this AD is not needed since Part 7 of the Accomplishment Instructions of Boeing Special Attention Service Bulletin 737-32-1486, dated November 6, 2014, is already cited in paragraph (j)(3) of this AD as terminating action for the actions required by paragraph

(i)of this AD. We have not changed this AD in this regard. Request To Clarify “New” Part EASA stated that the NPRM does not explicitly state that replacement with a new part is acceptable unless the new part belongs to “Appendix D (wrong batch).” We are not sure what EASA intended by the term “new.” This would ordinarily indicate a brand new part obtained from the design approval holder or authorized supplier that has never previously been placed into service. However, we infer from EASA's statement that it intends the term to mean a different part than what is currently installed on the airplane. If this is the case, then this issue is already addressed in the service information. For example, for replacement of the entire MLG, Part 8 of the Accomplishment Instructions of Boeing Special Attention Service Bulletin 737-32-1486, dated November 6, 2014, specifies that such replacement be accomplished with a serviceable MLG. By definition, the components listed in Appendix D of SASB 737-32-1486, R1 are not serviceable. We have not changed this AD in this regard. Requests To Clarify/Revise Overhaul Procedures and Clarify Component Installations SunExpress requested clarification that overhaul of affected components/assemblies specified in the service information is terminating action for inspections. SunExpress stated that the service information has a note specifying to not reinstall a removed component and/or MLG on another airplane until overhaul is completed. United Airlines

(UAL)requested that we revise paragraph

(l)of the proposed AD to allow operators to install affected parts as long as they have been overhauled using the component maintenance manual and Boeing Special Attention Service Bulletin 737-32-1486, dated November 6, 2014, as revised by SASB 737-32-1486, R1. UAL stated that the wording in paragraph

(l)of the proposed AD implies that all affected serial numbers would need FAA approval for repair/overhaul. In addition, SunExpress requested clarification as to whether each sub-part or sub-assembly under an MLG component installation is also affected individually. SunExpress asked if, for example, a sub-part ( *e.g.,* inner cylinder) that was previously installed on an MLG assembly affected by the proposed AD would be subject to the AD requirements if it is installed on a different unaffected MLG assembly. We partially agree with the commenters' requests. We find that the instructions in the service information for overhaul, as specified in the NPRM, already address the commenters' concerns. However, we agree that additional clarification would be helpful. We have revised paragraph

(l)of this AD to specify, in part, that an MLG may not be installed unless that MLG has been overhauled as specified in the applicable corrective actions of paragraphs

(h)and

(i)of this AD, or using a method approved in accordance with the procedures specified in paragraph

(m)of this AD. In addition, to address SunExpress's comment concerning component installations, we provide the following clarification. Based on accepted maintenance practices, a part number would include all of the components that make up that part. It is incumbent upon the operator to either inspect or do a records review to identify those parts affected by this AD. Any parts identified, including all components of those parts, are affected. As stated previously, we have revised paragraph

(l)of this AD to provide clarification. Request To Extend Proposed Compliance Time SunExpress requested that we revise the proposed compliance time for the MLG inspections from 24 months to 36 months to accommodate its maintenance schedule. SunExpress pointed out that the longer compliance time would be financially beneficial for operators. We do not agree with SunExpress's request to extend the compliance time. The operator provided no technical justification for revising this compliance time. Stress corrosion cracking of the external surfaces of the MLG is a significant safety issue, and we have determined that the proposed inspection threshold is warranted, based on the effectiveness of the inspection procedure and the FAA transport airplane risk assessment. In developing an appropriate compliance time for this AD, we considered the safety issues as well as the recommendations of the manufacturer, the availability of necessary parts, and the practical aspect of accomplishing the required inspection within an interval of time that corresponds to the normal maintenance schedules of most affected operators. We considered the manufacturer's recommendation as well as the time necessary to complete the rulemaking process, and found that a 24-month initial compliance time should fall well within the time that the majority of operators have regular maintenance visits scheduled. In light of these factors, we have determined that the 24-month initial compliance time, as proposed, is appropriate. We have not changed this AD in this regard. Effect of Winglets on Accomplishment of the Proposed Actions Aviation Partners Boeing stated that accomplishing Supplemental Type Certificate

(STC)ST00830SE does not affect the actions specified in the NPRM. We concur with the commenter. We have redesignated paragraph

(c)of the proposed AD as (c)(1) and added new paragraph (c)(2) to this AD to state that installation of STC ST00830SE does not affect the ability to accomplish the actions required by this final rule. Therefore, for airplanes on which STC ST00830SE is installed, a “change in product” AMOC approval request is not necessary to comply with the requirements of 14 CFR 39.17. 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 for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM. We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD. Related Service Information Under 1 CFR Part 51 We reviewed Boeing Special Attention Service Bulletin 737-32-1486, dated November 6, 2014, as revised by SASB 737-32-1486, R1. The service information describes procedures for identifying affected parts, repetitive external surface detailed inspections for damage of affected parts, and related investigative and corrective actions if necessary. For certain airplanes, the service information describes procedures for a detailed inspection and bushing replacement of the trunnion bore, and related investigative and corrective actions. The service information also describes procedures for certain airplanes for a detailed inspection of the trunnion bore, and corrective actions. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section. Costs of Compliance We estimate that this AD affects 33 airplanes of U.S. registry. We estimate the following costs to comply with this AD: Estimated Costs Action Labor cost Parts cost Cost per product Cost on U.S. operators External surface detailed inspection Up to 16 work-hours × $85 per hour = $1,360 per inspection cycle $0 $1,360 per inspection cycle Up to $44,880 per inspection cycle. Outer cylinder assembly trunnion bore detailed inspection and bushing replacement (Groups 1-2, configuration 1) 70 work-hours × $85 per hour = $5,950 Negligible $5,950 $196,350. We estimate the following costs to do any necessary replacements that would be required based on the results of the inspections. We have no way of determining the number of aircraft that might need this replacement. On-Condition Costs Action Labor cost Cost per product Outer cylinder assembly replacement (if required as a result of the outer cylinder assembly trunnion bore detailed inspection) 28 work-hours × $85 per hour = $2,380 $2,380 We have received no definitive data that would enable us to provide cost estimates for certain on-condition actions (MLG external surface repair, MLG component replacement, outer cylinder repair, and MLG replacement) specified in this AD. According to the manufacturer, some of the costs of this 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. The previous information is based on known affected airplanes. However, the MLG may have been overhauled outside of the Boeing Exchange Program as specified in the “Clarification of Affected MLGs” section of 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 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 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. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by adding the following new airworthiness directive (AD): **2017-04-11 The Boeing Company:** Amendment 39-18806; Docket No. FAA-2016-5468; Directorate Identifier 2015-NM-021-AD.

(a)Effective Date This AD is effective March 29, 2017.

(b)Affected ADs None.

(c)Applicability

(1)This AD applies to all The Boeing Company Model 737-600, -700, -700C, -800, and -900 series airplanes, certificated in any category.

(2)Installation of Supplemental Type Certificate

(STC)ST00830SE ( *http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgstc.nsf/0/184DE9A71EC3FA5586257EAE00707DA6?OpenDocument&Highlight=st00830se* ) does not affect the ability to accomplish the actions required by this AD. Therefore, for airplanes on which STC ST00830SE 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.

(d)Subject Air Transport Association

(ATA)of America Code 32, Landing Gear.

(e)Unsafe Condition This AD was prompted by reports of paint deterioration on the surface of the main landing gear

(MLG)and early onset of corrosion in the trunnion bore of the MLG outer cylinder. We are issuing this AD to prevent stress corrosion cracking of the external surfaces of the MLG, which could result in a fracture of the MLG and consequent MLG collapse.

(f)Compliance Comply with this AD within the compliance times specified, unless already done.

(g)Inspection for Affected Part/Serial Numbers At the applicable time specified in table 1 of paragraph 1.E., “Compliance,” of Boeing Special Attention Service Bulletin 737-32-1486, dated November 6, 2014, as revised by Boeing Special Attention Service Bulletin 737-32-1486, Revision 1, dated April 1, 2015 (“SASB 737-32-1486, R1”), except as required by paragraph (k)(1) of this AD: Do the actions specified in paragraphs (g)(1) and (g)(2) of this AD in order to identify affected parts.

(1)Inspect the MLG to determine if it has any component installation or side strut assembly having a part number and serial number listed in Appendix D of Boeing Special Attention Service Bulletin 737-32-1486, dated November 6, 2014, as revised by SASB 737-32-1486, R1; except that the “Variable Number” column of Appendix D is to be disregarded in determining affected part and serial numbers. An MLG that has any MLG component installation or side strut assembly having a part number and serial number listed in Appendix D of Boeing Special Attention Service Bulletin 737-32-1486, dated November 6, 2014, as revised by SASB 737-32-1486, R1 is an affected part. A review of airplane maintenance records is acceptable in lieu of this inspection if the part number and serial number of the MLG component installation and side strut assembly can be conclusively identified from that review.

(2)Do a records review to determine if the MLG has been overhauled by Messier Services Asia Pte Ltd (MS Asia) outside of the Boeing Exchange program from June 1, 2009, to July 31, 2013. If it is determined that the MLG has been overhauled by MS Asia outside of the Boeing Exchange program from June 1, 2009, to July 31, 2013, that MLG is an affected part. If from the records review it cannot be conclusively determined that an overhauled MLG was overhauled by a maintenance, repair, and overhaul

(MRO)facility other than MS Asia, or if from the records review it cannot be conclusively determined that an MLG overhauled by MS Asia was part of the Boeing Exchange Program from June 1, 2009, to July 31, 2013, that MLG is an affected part.

(h)Requirements for Affected Parts If any affected part is identified during the inspection or records review required by paragraph

(g)of this AD: At the applicable time specified in table 3 of paragraph 1.E., “Compliance,” of Boeing Special Attention Service Bulletin 737-32-1486, dated November 6, 2014, as revised by SASB 737-32-1486, R1, except as required by paragraph (k)(1) of this AD, do detailed inspections of the external surfaces of the MLG, and do all applicable related investigative and corrective actions, in accordance with Parts 1, 3, and 4 of the Accomplishment Instructions of Boeing Special Attention Service Bulletin 737-32-1486, dated November 6, 2014, as revised by SASB 737-32-1486, R1, except as required by paragraph (k)(2) of this AD. Repeat the inspections thereafter at the applicable time specified in table 3 of paragraph 1.E., “Compliance,” of Boeing Special Attention Service Bulletin 737-32-1486, dated November 6, 2014, as revised by SASB 737-32-1486, R1. All applicable related investigative and corrective actions must be done before further flight.
