[Federal Register Volume 83, Number 223 (Monday, November 19, 2018)] [Proposed Rules] [Pages 58196-58199] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2018-25001] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2018-0961; Product Identifier 2018-NM-121-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 certain The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This proposed AD was prompted by reports indicating that the pitot heat switch is not always set to ON, which could result in misleading air data. This proposed AD would require replacement of pitot anti-icing system components, installation of a junction box and wiring provisions, repetitive testing of the anti- icing system, and applicable on-condition actions. We are proposing this AD to address the unsafe condition on these products. DATES: We must receive comments on this proposed AD by January 3, 2019. 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.

SUPPLEMENTARY INFORMATION: Comments Invited We invite you to send any written relevant data, views, or arguments about this proposal. Send your comments to an address listed under the ADDRESSES section. Include ``Docket No. FAA- [[Page 58197]] 2018-0961; Product Identifier 2018-NM-121-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 proposed AD. Discussion We have received reports indicating that the pitot heat switch is not always set to ON. The failure to activate the manually activated pitot anti-icing system likely resulted in misleading air data that contributed to an accident and three incidents involving Boeing Model 737 airplanes. This condition, if not addressed, could result in the air data sensors not being heated, which could allow ice to form on the sensors and cause erroneous air data. This erroneous air data can lead to loss of crew situational awareness and an inability to maintain continued safe flight and landing of the airplane. Related Service Information Under 1 CFR Part 51 We reviewed Boeing Alert Service Bulletin 737-30A1064, Revision 1, dated October 18, 2017. The service information describes procedures for replacement and repetitive testing of the P5-9 window and pitot heat module, changing the anti-icing system to automatically supply power to heat the air data sensors. If flight crews fail to activate it manually, the anti-icing system will come on automatically after engine start. We also reviewed the following concurrent service information. Boeing Service Bulletin 737-30-1067, Revision 1, dated May 4, 2017. This service information describes procedures for installing a new J18 junction box to change the anti-icing system. Boeing Service Bulletin 737-30-1068, Revision 1, dated May 4, 2017. This service information describes procedures for installing wiring provisions to the anti-icing system. 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. Minimum Equipment List (MEL) Provision Operators are required by 14 CFR part 91 to have an MEL to operate with inoperable equipment. Paragraph (l) of this proposed AD allows for the operation of the airplane even if the modified air data probe heat (ADPH) system is inoperable, so long as the operator's MEL has a provision to allow for this inoperability. 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 accomplishment of the actions identified as ``RC'' (required for compliance) in the Accomplishment Instructions of Boeing Alert Service Bulletin 737-30A1064, Revision 1, dated October 18, 2017, described previously, except for any differences identified as exceptions in the regulatory text of this proposed AD. This proposed AD would also require accomplishing the actions specified in Boeing Service Bulletin 737-30-1067, Revision 1, dated May 4, 2017; and Boeing Service Bulletin 737-30-1068, Revision 1, dated May 4, 2017, described previously. 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-2018-0961. Costs of Compliance We estimate that this proposed AD affects 296 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 ---------------------------------------------------------------------------------------------------------------- Replacement (Boeing Alert 6 work-hours x $85 per $0 $510............... $150,960. Service Bulletin 737-30A1064). hour = $510. Repetitive tests (Boeing Alert 5 work-hours x $85 per 0 $425 per inspection $125,800 per Service Bulletin 737-30A1064). hour = $425 per cycle. inspection cycle. inspection cycle. J18 Junction box installation Up to 75 work-hours x 23,614 Up to $29,989...... Up to $8,876,744. (Boeing Service Bulletin 737-30- $85 per hour = $6,375. 1067). Installation of wire provisions Up to 193 work-hours x 4,800 Up to $21,205...... Up to $6,276,680. (Boeing Service Bulletin 737-30- $85 per hour = $16,405. 1068). ---------------------------------------------------------------------------------------------------------------- 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. 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 [[Page 58198]] 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-2018-0961; Product Identifier 2018-NM-121-AD.

(j) Exceptions to Service Information Specifications For purposes of determining compliance with the requirements of this AD: Where Boeing Alert Service Bulletin 737-30A1064, Revision 1, dated October 18, 2017, uses the phrase ``the original issue date of this service bulletin,'' this AD requires using ``the effective date of this AD.'' (k) Credit for Previous Actions This paragraph provides credit for the actions specified in paragraph (h) of this AD, if those actions were performed before the effective date of this AD using Boeing Alert Service Bulletin 737- 30A1064, dated May 4, 2017, provided that step 15 for Groups 1 through 4, as applicable, of the Accomplishment Instructions of Boeing Alert Service Bulletin 737-30A1064, Revision 1, dated October 18, 2017, is done at the applicable times specified in paragraph 1.E., ``Compliance,'' of Boeing Alert Service Bulletin 737-30A1064, Revision 1, dated October 18, 2017, or within 180 days after the effective date of this AD, whichever occurs later. (l) Minimum Equipment List (MEL) In the event that the air data probe heat (ADPH) system as modified by this AD is inoperable, an airplane may be operated as specified in the operator's MEL, provided the MEL includes provisions that address the modified ADPH system. (m) 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. 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 certification office, send it to the attention of the person identified in paragraph (n)(2) 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 Branch, FAA, 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) For service information that contains steps that are labeled as RC, the provisions of paragraphs (m)(4)(i) and (m)(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.
