[Federal Register Volume 82, Number 105 (Friday, June 2, 2017)] [Proposed Rules] [Pages 25547-25549] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2017-11006] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2017-0503; Directorate Identifier 2017-NM-032-AD] RIN 2120-AA64 Airworthiness Directives; The Boeing Company Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD- 83), and DC-9-87 (MD-87) airplanes, and Model MD-88 airplanes. This proposed AD was prompted by reports of cracking of various structures in the bulkhead. This proposed AD would require an inspection for cracking in these structures, and corrective actions if necessary. We are proposing this AD to address the unsafe condition on these products. DATES: We must receive comments on this proposed AD by July 17, 2017. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods:Federal eRulemaking Portal: Go to http://www.regulations.gov.

[[Page 25548]] SUPPLEMENTARY INFORMATION: Comments Invited We invite you to send any written relevant data, views, or arguments about this proposed AD. Send your comments to an address listed under the ADDRESSES section. Include ``Docket No. FAA-2017-0503; Directorate Identifier 2017-NM-032-AD'' at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this NPRM. We will consider all comments received by the closing date and may amend this NPRM because of those comments. We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this NPRM. Discussion We have received reports of cracking of various structures in The Boeing Company Model DC-9-81 (MD-81), DC-9-82 (MD-82), and DC-9-83 (MD- 83) airplanes at the cant station 1463 bulkhead, and the Model DC-9-87 (MD-87) airplanes at the cant station 1254 bulkhead. One incident of cracking was discovered during a heavy maintenance visit on an airplane with 63,480 total flight hours, and 45,809 total flight cycles. The cracks were in the upper left area of the bulkhead, between longerons L-2 and L-3, in the frame web, horizontal stiffeners, lower frame cap, rear spar cap, and spar cap web. An analysis has determined that the operational and limit loads cannot duplicate this condition and the root cause is suspected to be the result of a high load event(s). This condition, if not corrected, could result in reduced structural integrity of the airplane. Related Service Information Under 1 CFR Part 51 We reviewed Boeing Alert Service Bulletin MD80-53A316, dated December 15, 2016. The service information describes procedures for a detailed inspection on the left and right sides of the forward and aft surfaces of cant station 1463 bulkhead and cant station 1254 bulkhead for cracking in the upper caps, upper cap doublers, bulkhead webs and doublers, stiffeners, lower caps, and vertical stabilizer rear spar caps and webs, between longerons L-11L through L-11R, 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. FAA's Determination We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of these same type designs. Proposed AD Requirements This proposed AD would require accomplishing the actions specified in the service information described previously, except as discussed under ``Differences Between this Proposed AD and the Service Information.'' For information on the procedures and compliance times, see this service information at http://www.regulations.gov by searching for and locating Docket No. FAA-2017-0503. The phrase ``corrective actions'' is used in this proposed AD. Corrective actions correct or address any condition found. Corrective actions in an AD could include, for example, repairs. Differences Between This Proposed AD and the Service Information Boeing Alert Service Bulletin MD80-53A316, dated December 15, 2016, specifies to contact the manufacturer for certain instructions, but this proposed AD would require using repair methods, modification deviations, and alteration deviations in one of the following ways: In accordance with a method that we approve; or Using data that meet the certification basis of the airplane, and that have been approved by the Boeing Commercial Airplanes Organization Designation Authorization (ODA) whom we have authorized to make those findings. Boeing Alert Service Bulletin MD80-53A316, dated December 15, 2016, specifies doing the inspection at cant station 1463 bulkhead for Model MD-88 airplanes. However, Model MD-88 airplanes are similar in design to Model DC-9-87 (MD-87) airplanes, and should instead be inspected at cant station 1254 bulkhead. Therefore, this proposed AD specifies that the proposed actions for Model MD-88 airplanes be accomplished using the Accomplishment Instructions for Model DC-9-87 (MD-87) airplanes in Boeing Alert Service Bulletin MD80-53A316, dated December 15, 2016. This difference has been coordinated with Boeing. Costs of Compliance We estimate that this proposed AD affects 361 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: Estimated Costs ---------------------------------------------------------------------------------------------------------------- Cost per Cost on U.S. Action Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- Inspection......................... 3 work-hours x $85 per hour $0 $255 $92,055 = $255. ---------------------------------------------------------------------------------------------------------------- We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this proposed 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 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 [[Page 25549]] 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. 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 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 adding the following new airworthiness directive (AD): The Boeing Company: Docket No. FAA-2017-0503; Directorate Identifier 2017-NM-032-AD. (a) Comments Due Date We must receive comments by July 17, 2017. (b) Affected ADs None. (c) Applicability This AD applies to all The Boeing Company Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), and DC-9-87 (MD-87) airplanes, and Model MD-88 airplanes, certificated in any category. (d) Subject Air Transport Association (ATA) of America Code 53; Fuselage. (e) Unsafe Condition This AD was prompted by reports of cracking of various structures at the cant station 1463 bulkhead and at the cant station 1254 bulkhead. We are issuing this AD to detect and correct cracking at the cant station 1463 bulkhead and cant station 1254 bulkhead, which could result in reduced structural integrity of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Inspection and Corrective Action Within 700 flight cycles or 6 months after the effective date of this AD, whichever occurs first, do a detailed inspection for cracking on the left and right sides of the forward and aft surfaces of the cant station 1463 bulkhead (for Model DC-9-81 (MD-81), DC-9- 82 (MD-82), and DC-9-83 (MD-83) airplanes) and cant station 1254 bulkhead (for DC-9-87 (MD-87) airplanes and MD-88 airplanes); and do all applicable corrective actions; in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin MD80- 53A316, dated December 15, 2016, except as required in paragraphs (h)(1) and (h)(2) of this AD. Do all applicable corrective actions before further flight. (h) Exceptions to Service Information (1) For Model MD-88 airplanes: This AD requires that instead of inspecting at cant station 1463 bulkhead, operators must inspect at cant station 1254 bulkhead, which is identified as ``DC-9-87 (MD-87) CANT STA 1254 BULKHEAD'' in the Accomplishment Instructions of Boeing Alert Service Bulletin MD80-53A316, dated December 15, 2016. (2) Where Boeing Alert Service Bulletin MD80-53A316, dated December 15, 2016, specifies to contact Boeing for appropriate action and specifies that action as ``RC'' (Required for Compliance): Before further flight, repair the cracking using a method approved in accordance with the procedures specified in paragraph (k) of this AD. (i) Credit for Previous Actions This paragraph provides credit for the actions specified in paragraph (g) of this AD, if those actions were performed before the effective date of this AD using Boeing Multi Operator Message MOM- MOM-16-0684-01B, dated October 7, 2016. (j) Special Flight Permit Special flight permits, as described in Section 21.197 and Section 21.199 of the Federal Aviation Regulations (14 CFR 21.197 and 21.199), may be issued to operate the airplane to a location where the requirements of this AD can be accomplished, but concurrence by the Manager, Los Angeles Aircraft Certification Office (ACO), FAA, is required before issuance of the special flight permit. (k) Alternative Methods of Compliance (AMOCs) (1) The Manager, Los Angeles ACO, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or local Flight Standards District Office, as appropriate. If sending information directly to the manager of the ACO, send it to the attention of the person identified in paragraph (l)(1) of this AD. Information may be emailed to: [email protected]. (2) Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the local flight standards district office/certificate holding district office. (3) An AMOC that provides an acceptable level of safety may be used for any repair, modification, or alteration required by this AD if it is approved by the Boeing Commercial Airplanes Organization Designation Authorization (ODA) that has been authorized by the Manager, Los Angeles ACO, to make those findings. To be approved, the repair method, modification deviation, or alteration deviation must meet the certification basis of the airplane, and the approval must specifically refer to this AD. (4) Except as required by paragraph (h) of this AD: For service information that contains steps that are labeled as Required for Compliance (RC), the provisions of paragraphs (k)(4)(i) and (k)(4)(ii) of this AD apply. (i) The steps labeled as RC, including substeps under an RC step and any figures identified in an RC step, must be done to comply with the AD. If a step or substep is labeled ``RC Exempt,'' then the RC requirement is removed from that step or substep. An AMOC is required for any deviations to RC steps, including substeps and identified figures. (ii) Steps not labeled as RC may be deviated from using accepted methods in accordance with the operator's maintenance or inspection program without obtaining approval of an AMOC, provided the RC steps, including substeps and identified figures, can still be done as specified, and the airplane can be put back in an airworthy condition.
