                Airworthiness Directives; The Boeing Company Airplanes
                AGENCY: Federal Aviation Administration (FAA), DOT.
                ACTION: Notice of proposed rulemaking (NPRM).
                -----------------------------------------------------------------------
                SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD)
                2016-25-29, which applies to certain The Boeing Company Model 767-200
                and -300 series airplanes. AD 2016-25-29 requires replacing the cargo
                compartment insulation blankets on the left and right sides with new
                insulation blankets that incorporate fire stops. Since the FAA issued
                AD 2016-25-29, it was determined that an incorrect part number was
                specified for certain insulation blankets, and the FAA has determined
                that additional insulation blankets need to be replaced and that
                additional airplanes are subject to the unsafe condition. This proposed
                AD would continue to require the actions in AD 2016-25-29 for certain
                airplanes. This proposed AD would also add airplanes to the
                applicability and would require a general visual inspection of the
                replacement insulation blankets to determine if the blankets are in
                serviceable condition and correctly installed, and applicable on-
                condition actions. For certain airplanes, this AD would also require an
                inspection to determine the insulation blanket part number installed;
                replacement of additional insulation blankets; and applicable on-
                condition actions. The FAA is proposing this AD to address the unsafe
                condition on these products.
                DATES: The FAA must receive comments on this proposed AD by September
                24, 2020.
                ADDRESSES: You may send comments, using the procedures found in 14 CFR

                SUPPLEMENTARY INFORMATION:
                Comments Invited
                 The FAA invites 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-2020-0680;
                Product Identifier 2020-NM-079-AD'' at the beginning of your comments.
                The most helpful comments reference a specific portion of the proposal,
                explain the reason for any recommended change, and include supporting
                data. The FAA will consider all comments received by the closing date
                and may amend this NPRM because of those comments.
                 Except for Confidential Business Information (CBI) as described in
                the following paragraph, and other information as described in 14 CFR
                11.35, the FAA will post all comments received, without change, to
                https://www.regulations.gov, including any personal information you
                provide. The FAA will also post a report summarizing each substantive
                verbal contact received about this proposed AD.
                Confidential Business Information
                 CBI is commercial or financial information that is both customarily
                and actually treated as private by its owner. Under the Freedom of
                Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public
                disclosure. If your comments responsive to this NPRM contain commercial
                or financial information that is customarily treated as private, that
                you actually treat as private, and that is relevant or responsive to
                this NPRM, it is important that you clearly designate the submitted
                comments as CBI. Please mark each page of your submission containing
                CBI as ``PROPIN.'' The FAA will treat such marked submissions as
                confidential under the FOIA, and they will not be placed in the public
                docket of this NPRM. Submissions containing CBI should be sent to the
                person identified in the FOR FURTHER INFORMATION CONTACT section. Any
                commentary that the FAA receives which is not specifically designated
                as CBI will be placed in the public docket for this rulemaking.
                Discussion
                 The FAA issued AD 2016-25-29, Amendment 39-18755 (81 FR 94956,
                December 27, 2016) (``AD 2016-25-29''), for certain The Boeing Company
                Model 767-200 and -300 series airplanes. AD 2016-25-29 requires
                replacing the cargo compartment
                [[Page 48123]]
                insulation blankets on the left and right sides with new insulation
                blankets that incorporate fire stops. AD 2016-25-29 resulted from a
                report of a fire in the bilge area of the cargo compartment that burned
                through the insulation blankets that were intended to prevent smoke
                from migrating behind the cargo compartment sidewall liners and upward
                into the main cabin. The FAA issued AD 2016-25-29 to address a fire in
                the bilge area of the cargo compartment burning through the insulation
                blankets and consequently allowing smoke to migrate behind the cargo
                compartment sidewall liners and upward into the main cabin.
                Actions Since AD 2016-25-29 Was Issued
                 Since the FAA issued AD 2016-25-29, it was determined that an
                incorrect part number was specified for certain insulation blankets.
                Based on those findings, the FAA determined that certain insulation
                blankets that were replaced, as required by AD 2016-25-29, must be
                replaced with those having the improved design. In addition, the FAA
                determined that additional insulation blankets need to be replaced and
                that additional airplanes are subject to the unsafe condition.
                Related Service Information Under 1 CFR Part 51
                 The FAA reviewed Boeing Special Attention Service Bulletin 767-25-
                0550, Revision 1, dated December 4, 2019. The service information
                describes procedures for replacing cargo compartment insulation
                blankets between stringers 29 and 33, on the left and right sides, with
                new insulation blankets that incorporate fire stops; an inspection to
                determine the insulation blanket part number installed between
                stringers 29 and 33, on the left and right sides; a general visual
                inspection of the replacement insulation blankets between stringers 29
                and 33, on the left and right sides to determine if the blankets are in
                serviceable condition and correctly installed; and applicable on-
                condition actions. On-condition actions include repair, replacement,
                and correction of insulation blanket installations.
                 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
                 The FAA is proposing this AD because the agency 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
                 Although this proposed AD does not explicitly restate the
                requirements of AD 2016-25-29, this proposed AD would retain certain of
                the requirements of AD 2016-25-29. Those requirements are referenced in
                the service information identified previously, which, in turn, is
                referenced in paragraph (g) of this proposed AD. This proposed AD would
                add airplanes to the applicability. This proposed AD would also require
                accomplishment of the actions identified as ``RC'' (required for
                compliance) in the Accomplishment Instructions of Boeing Special
                Attention Service Bulletin 767-25-0550, Revision 1, dated December 4,
                2019, described previously.
                 For information on the procedures and compliance times, see this
                service information at https://www.regulations.gov by searching for and
                locating Docket No. FAA-2020-0680.
                Costs of Compliance
                 The FAA estimates that this proposed AD affects 329 airplanes of
                U.S. registry. The FAA estimates 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 (retained actions Up to 54 work- *................. Up to $4,590...... Up to $1,510,110.
                 from AD 2016-25-29). hours x $85 per
                 hour = Up to
                 $4,590.
                Inspections and replacements Up to 62 work-hour Up to $35,900..... Up to $41,170..... Up to $13,944,530.
                 (new proposed action). x $85 per hour =
                 Up to $5,270.
                ----------------------------------------------------------------------------------------------------------------
                * The FAA has received no definitive data that would enable providing parts cost estimates for the retained
                 actions specified in this proposed AD.
                 The FAA has received no definitive data that would enable us to
                provide cost estimates for the on-condition actions specified in this
                proposed AD.
                 According to the manufacturer, some of the costs of this proposed
                AD may be covered under warranty, thereby reducing the cost impact on
                affected individuals. The FAA does not control warranty coverage for
                affected individuals. As a result, the FAA has included all available
                costs in our cost estimate.
                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.
                 The FAA is 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
                 The FAA has 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 that the proposed
                regulation:
                 (1) Is not a ``significant regulatory action'' under Executive
                Order 12866,
                 (2) Will not affect intrastate aviation in Alaska, and
                 (3) Will not have a significant economic impact, positive or
                negative,
                [[Page 48124]]
                on a substantial number of small entities under the criteria of the
                Regulatory Flexibility Act.

                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 removing Airworthiness Directive (AD)
                2016-25-29, Amendment 39-18755 (81 FR 94956, December 27, 2016), and
                adding the following new AD:
                The Boeing Company: Docket No. FAA-2020-0680; Product Identifier
                2020-NM-079-AD.
                (a) Comments Due Date
                 The FAA must receive comments on this AD action by September 24,
                2020.
                (b) Affected ADs
                 This AD replaces AD 2016-25-29, Amendment 39-18755 (81 FR 94956,
                December 27, 2016) (``AD 2016-25-29'').
                (c) Applicability
                 This AD applies to The Boeing Company Model 767-200, -300, -
                300F, and -400ER series airplanes, certificated in any category, as
                identified in Boeing Special Attention Service Bulletin 767-25-0550,
                Revision 1, dated December 4, 2019.
                (d) Subject
                 Air Transport Association (ATA) of America Code 25, Equipment/
                furnishings.
                (e) Unsafe Condition
                 This AD was prompted by a report of a fire in the bilge area of
                the cargo compartment that burned through the insulation blankets
                that were intended to prevent smoke from migrating behind the cargo
                compartment sidewall liners and upward into the main cabin. The FAA
                is issuing this AD to address a fire in the bilge area of the cargo
                compartment, which if not contained could lead to a possible smoke
                and fire event in the passenger compartment.
                (f) Compliance
                 Comply with this AD within the compliance times specified,
                unless already done.
                (g) Required Actions
                 Except as specified by paragraph (h) of this AD: At the
                applicable times specified in paragraph 1.E., ``Compliance,'' of
                Boeing Special Attention Service Bulletin 767-25-0550, Revision 1,
                dated December 4, 2019, do all applicable actions identified as
                ``RC'' (required for compliance) in, and in accordance with, the
                Accomplishment Instructions of Boeing Special Attention Service
                Bulletin 767-25-0550, Revision 1, dated December 4, 2019.
                (h) Exception to Service Information Specifications
                 Where Boeing Special Attention Service Bulletin 767-25-0550,
                Revision 1, dated December 4, 2019, uses the phrase ``the Revision 1
                date of this service bulletin,'' this AD requires using ``the
                effective date of this AD.''
                (i) Alternative Methods of Compliance (AMOCs)
                 (1) The Manager, Seattle 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 (j)(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 Company Organization Designation
                Authorization (ODA) that has been authorized by the Manager, Seattle
                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) AMOCs approved previously for AD 2016-25-29 are approved as
                AMOCs for the corresponding provisions of Boeing Special Attention
                Service Bulletin 767-25-0550, Revision 1, dated December 4, 2019,
                that are required by paragraph (g) of this AD.
                 (5) For service information that contains steps that are labeled
                as Required for Compliance (RC), the provisions of paragraphs
                (i)(5)(i) and (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.
