[Federal Register Volume 83, Number 35 (Wednesday, February 21, 2018)] [Proposed Rules] [Pages 7425-7428] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2018-03433] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2018-0112; Product Identifier 2017-NM-161-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 737-100, -200, -200C, -300, -400, -500 series airplanes. This proposed AD was prompted by reports of cracking in certain flanges, and the adjacent web, of the wing outboard flap track at certain positions. This proposed AD would require an inspection to determine the part number of the wing outboard flap track assembly; repetitive inspections of each affected wing outboard flap track for discrepancies, and applicable on-condition actions; and repetitive overhaul of each wing outboard flap track. We are proposing this AD to address the unsafe condition on these products. DATES: We must receive comments on this proposed AD by April 9, 2018. 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.

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 proposed AD. Discussion We have received a report indicating that during the tear down of a Model 737-300 airplane, cracking was found in the inboard lower flange and adjacent web near the forward attachment of the outboard flap track at position 8. The cracked flap track had accumulated 1,579 flight cycles since it was installed on the airplane after the most recent overhaul, and approximately 20,000 flight cycles since new. The metallurgical evaluation of the cracked flap track found that stress corrosion cracking originated from a fastener hole in the flap track web with missing cadmium plating. There was not sufficient evidence to conclude that the missing cadmium plating was the cause or the result of the cracking. Boeing has since received one more report of cracking in the outboard lower flange and the adjacent web of the outboard flap track at position 8 on a different Model 737-300 airplane. The crack was also found near the forward attachment, but did not originate from a fastener hole. The cracked flap track had accumulated 1,175 flight cycles since it was installed on the airplane. Boeing determined that the existing inspection programs are not sufficient to find such cracks before failure of a flap track could occur. Cracking in the area between the forward and rear spar attachments of the wing outboard flap tracks may lead to the inability of a principal structural element to sustain required flight load, such cracking could result in loss of the outboard trailing edge flap and consequent reduced controllability of the airplane. Related Rulemaking AD 2013-09-02, Amendment 39-17443 (78 FR 27010, May 9, 2013) (``AD 2013-09-02''), requires operators to use Boeing Service Bulletin (SB) 737-57A1271, Revision 3, dated February 13, 2012 (``SB 737-57A1271 R3''), to accomplish the inspections required by paragraph (p) of that AD. Boeing SB 737-57A1271 was issued to address more than 30 reports of stress corrosion cracks in the wing outboard flap tracks at positions 2 and 7, and provides instructions to do detailed and non-destructive test (NDT) inspections of the flap track flanges and webs, and detailed and NDT inspections of the flap track at the rear spar attachment. Boeing SB 737-57A1271 also gives instructions to repair, overhaul, and replace the wing outboard flap tracks at positions 2 and 7. Boeing SB 737-57A1271 does not include NDT inspections of the flap track flanges at the attachment of the flap transmission and the hinge support assembly, or NDT inspections of the flap track webs forward of the rear spar attachment nor repair, overhaul, and replacement of the wing outboard flap tracks at positions 1 and 8. As discussed above, Boeing reported information that indicates additional areas of stress corrosion cracks in other positions of the wing outboard flap tracks and the adjacent web of the outboard flap tracks. Therefore, the existing requirements of AD 2013-09-02 do not fully address the unsafe condition. Related Service Information Under 1 CFR Part 51 We reviewed Boeing Alert Requirements Bulletin 737-57A1338 RB, dated September 25, 2017. The service information describes procedures for repetitive inspections, repair, repetitive overhaul, and replacement of the wing outboard flap tracks, and applicable on- condition 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 the same type design. Proposed AD Requirements This proposed AD would require new NDT inspections of the flap track flanges and webs forward of the rear spar attachment, in areas not previously inspected using SB 737-57A1271 R3 (or previous revisions), to the existing requirements in AD 2013-09-02. The new and existing requirements would also apply to the wing outboard flap tracks at positions 1 and 8. Accomplishment of the inspections, repair, overhaul, and replacement of the wing outboard flap tracks specified in Boeing Alert Requirements Bulletin 737-57A1338 RB, dated September 25, 2017, would replace the instruction in SB 737-57A1271 R3 (or previous revisions), and terminates the requirements of AD 2013-09-02. This proposed AD would require accomplishment of the actions identified in the Boeing Alert Requirements Bulletin 737-57A1338 RB, dated September 25, 2017, described previously, except for any differences identified as exceptions in the regulatory text of this proposed AD. 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-2018-0112. Explanation of Requirements Bulletin The FAA worked in conjunction with industry, under the Airworthiness Directives Implementation Aviation Rulemaking Committee (AD ARC), to enhance the AD system. One enhancement is a process for annotating which steps in the service information are ``required for compliance'' (RC) with an AD. Boeing has implemented this RC concept into Boeing service bulletins. In an effort to further improve the quality of ADs and AD-related Boeing service information, a joint process improvement initiative was worked between the FAA and Boeing. The initiative resulted in the development of a new process in which the service information more clearly identifies the actions needed to address the unsafe condition in the ``Accomplishment Instructions.'' The new process results in a Boeing Requirements Bulletin, which contains only the actions needed to address the unsafe condition (i.e., only the RC actions). [[Page 7427]] Costs of Compliance We estimate that this proposed AD affects 160 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: Estimated Costs for Required Actions ---------------------------------------------------------------------------------------------------------------- Cost on U.S. Action Labor cost Parts cost Cost per product operators ---------------------------------------------------------------------------------------------------------------- Inspection (positions 1 and 8; 78 work-hours x $85 per $0 $6,630 per $1,060,800 per Group 2 and Group 3, hour = $6,630 per inspection cycle. inspection cycle. configuration 1). inspection cycle.

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. This proposed AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes to the Director of the System Oversight Division. 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. 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-2018-0112; Product Identifier 2017-NM-161-AD. (a) Comments Due Date We must receive comments by April 9, 2018. (b) Affected ADs This AD affects AD 2013-09-02, Amendment 39-17443 (78 FR 27010, May 9, 2013) (``AD 2013-09-02'').

(e) Unsafe Condition This AD was prompted by reports of cracking in certain flanges, and the adjacent web, of the wing outboard flap track at certain positions. We are issuing this AD to detect and correct cracking of the rear spar attachment, and cracking of the wing outboard flap tracks. Cracking in the area between the forward and rear spar attachments of the wing outboard flap tracks could lead to the inability of a principal structural element to sustain required flight load, and result in loss of the outboard trailing edge flap and consequent reduced controllability of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Required Actions for Group 1 Airplanes For airplanes identified as Group 1 in Boeing Alert Requirements Bulletin 737-57A1338 RB, dated September 25, 2017: Within 120 days after the effective date of this AD, do actions to correct the unsafe condition using a method approved in accordance with the procedures specified in paragraph (l) of this AD. (h) Required Actions For airplanes not specified in paragraph (g) of this AD: Except as required by paragraph (i) of this AD, at the applicable times specified in the ``Compliance'' paragraph of Boeing Alert Requirements Bulletin 737-57A1338 RB, dated September 25, 2017, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Alert Requirements [[Page 7428]] Bulletin 737-57A1338 RB, dated September 25, 2017. Note 1 to paragraph (h) of this AD: Guidance for accomplishing the actions required by this AD can be found in Boeing Alert Service Bulletin 737-57A1338, dated September 25, 2017, which is referred to in Boeing Alert Requirements Bulletin 737-57A1338 RB, dated September 25, 2017. (i) Exceptions to Service Information Specifications For purposes of determining compliance with the requirements of this AD: Where Boeing Alert Requirements Bulletin 737-57A1338 RB, dated September 25, 2017, uses the phrase ``the original issue date of Requirements Bulletin 737-57A1338 RB,'' this AD requires using ``the effective date of this AD.'' (j) Terminating Action for Requirements of AD 2013-09-02 Accomplishment of the requirements specified in paragraph (h) of this AD terminates all of the requirements specified in AD 2013-09- 02. (k) Parts Installation Limitation As of the effective date of this AD, no person may install, on any airplane, a wing outboard flap track having a part number listed in paragraph 1.B. of Boeing Alert Requirements Bulletin 737-57A1338 RB, dated September 25, 2017, unless the inspections and corrective actions specified in the Accomplishment Instructions of Boeing Alert Requirements Bulletin 737-57A1338 RB, dated September 25, 2017, are accomplished prior to the part's installation on the airplane. (l) Alternative Methods of Compliance (AMOCs) (1) The Manager, Los Angeles ACO Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.
