SUPPLEMENTARY INFORMATION: Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain The Boeing Company Model 767–200, –300, and –400ER series airplanes. The NPRM published in the Federal Register on June 26, 2024 (89 FR 53367). The NPRM was prompted by a report of multiple engine indicating and crew alerting system messages during the potable water servicing for a Model 777 freighter VerDate Sep<11>2014 18:38 Jan 30, 2025 Jkt 265001 airplane. The cause was found to be the separation of a fitting and steel water supply tube at a location above an electronics equipment cooling air filter, behind the forward cargo compartment left sidewall. The water from the soaked filter was then blown by the equipment cooling system onto multiple line replaceable units in the main electronics center. Model 767 passenger airplanes are similar in design to Model 777 freighter airplane. In the NPRM, the FAA proposed to require installation of hoseducts around the left-side section 43 potable water supply hoses and connections, a potable water system leakage test, and applicable corrective actions. The FAA is issuing this AD to address water leakage from the potable water system near the equipment cooling supply air inlet. The unsafe condition, if not addressed, could damage main electronics center components and result in loss of continued safe flight and landing. Related Rulemaking To address the identified unsafe condition on Model 777F series airplanes, the FAA issued AD 2021–06– 03, Amendment 39–21469 (86 FR 12809, March 5, 2021), as an interim action that required deactivation of the potable water system. The FAA followed with AD 2022–23–10, Amendment 39–22237 (87 FR 73448, November 30, 2022). Discussion of Final Airworthiness Directive Comments The FAA received comments from the Air Line Pilots Association, International (ALPA), Boeing, and United Airlines (UAL), who supported the NPRM without change. The FAA received additional comments from Aviation Partners Boeing (APB), Delta Air Lines (Delta), United Parcel Service Co. (UPS Airlines), and Air Canada. The following presents the comments received on the NPRM and the FAA’s response to each comment. Effect of Winglets on Accomplishment of the Proposed Actions APB stated that the installation of winglets per Supplemental Type Certificate (STC) ST01920SE does not affect compliance with the proposed actions. The FAA agrees with the commenter. The installation of STC ST01920SE does not affect the ability to accomplish the actions required by this AD. The FAA has not changed this AD in this regard. PO 00000 Frm 00005 Fmt 4700 Sfmt 4700 8659 Request To Correct a Part Name in Boeing Service Bulletin Delta requested that the FAA add an exception to paragraph (h) of the proposed AD as follows: Where the ‘‘Name’’ column for P/N NAS43DD6– 24FC in step 5 of figure 11 and step 5 of figure 13 in Boeing Alert Requirements Bulletin 767–38A0076 RB, dated December 1, 2023, states ‘‘SPACERS FOR BOLTS,’’ this AD requires using ‘‘SPACER FOR BOLT.’’ Only one spacer needs to be installed. The FAA agrees with the request. Only one spacer is to be installed in step 5 of figure 11 and step 5 of figure 13. The FAA has added paragraph (h)(2) to this AD accordingly. Requests for Excluding Boeing Model 767–300 Bedek Special Freighters in Applicability UPS Airlines requested that the FAA add the following statement to this AD: ‘‘This AD is not applicable to 767–300 airplanes listed in the Boeing Alert Requirements Bulletin 767–38A0076 RB, dated December 1, 2023, that were converted by Israel Aerospace Industries (IAI) STC number ST02040SE to freighter configuration where the subject hoses were removed.’’ UPS Airlines stated that it operates Boeing Model 767–300 series airplanes converted to freighter configuration by IAI, known as 767–300 Bedek Special Freighter (BDSF) fleet. The potable water hoses indicated in the Boeing service bulletin have been removed during freighter conversion by IAI STC number ST02040SE to freighter configuration. Similarly, Air Canada requested that the FAA add a statement stating that this AD is not applicable to any Boeing Model 767–300 passenger airplanes listed in Boeing Alert Requirements Bulletin 767–38A0076 RB, dated December 1, 2023, that have been modified to a 767–300BDSF configuration. Air Canada operates six Model 767–300 airplanes that were modified to an all-cargo configuration as per IAI STC ST02040SE. During this modification the water system was removed similar to the Boeing Model 767–300 converted freighter airplanes. The FAA agrees with the requests. The potable water hoses indicated in Boeing Alert Requirements Bulletin 767–38A0076 RB, dated December 1, 2023, have been removed during freighter conversion by IAI STC number ST02040SE to freighter configuration. The FAA has revised paragraph (c) of this AD accordingly. Conclusion The FAA reviewed the relevant data, considered any comments received, and E:\FR\FM\31JAR1.SGM 31JAR1 8660 Federal Register / Vol. 90, No. 20 / Friday, January 31, 2025 / Rules and Regulations determined that air safety requires adopting this AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on these products. Except for minor editorial changes, and any other changes described previously, this AD is adopted as proposed in the NPRM. None of the changes will increase the economic burden on any operator. Material Incorporated by Reference Under 1 CFR Part 51 The FAA reviewed Boeing Alert Requirements Bulletin 767–38A0076 RB, dated December 1, 2023. This material specifies procedures for the following actions at the lower lobe section 43 potable water system plumbing on the left-side: • Installing hoseducts and support clamps. • Installing spray shields, new tie straps on the supply hose, and tee fitting shrouds, depending on the airplane configuration. • Replacing the supply hoses and tee fittings for certain airplane configurations. • Doing a potable water system leakage test and, for any leakage found, repeating the test until no leakage is found. This material 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 The FAA estimates that this AD affects 397 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: ESTIMATED COSTS Action Install hose ducts, connections, and leakage test. Labor cost Up to 19 work-hours × $85 per hour = $1,615. The FAA has included all known costs in its cost estimate. According to the manufacturer, however, some or all of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected operators. 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. ddrumheller on DSK120RN23PROD with RULES1 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.

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to certain The Boeing 
Company Model 767-200, -300, and -400ER series airplanes. The NPRM 
published in the Federal Register on June 26, 2024 (89 FR 53367). The 
NPRM was prompted by a report of multiple engine indicating and crew 
alerting system messages during the potable water servicing for a Model 
777 freighter airplane. The cause was found to be the separation of a 
fitting and steel water supply tube at a location above an electronics 
equipment cooling air filter, behind the forward cargo compartment left 
sidewall. The water from the soaked filter was then blown by the 
equipment cooling system onto multiple line replaceable units in the 
main electronics center. Model 767 passenger airplanes are similar in 
design to Model 777 freighter airplane. In the NPRM, the FAA proposed 
to require installation of hoseducts around the left-side section 43 
potable water supply hoses and connections, a potable water system 
leakage test, and applicable corrective actions. The FAA is issuing 
this AD to address water leakage from the potable water system near the 
equipment cooling supply air inlet. The unsafe condition, if not 
addressed, could damage main electronics center components and result 
in loss of continued safe flight and landing.

Related Rulemaking

    To address the identified unsafe condition on Model 777F series 
airplanes, the FAA issued AD 2021-06-03, Amendment 39-21469 (86 FR 
12809, March 5, 2021), as an interim action that required deactivation 
of the potable water system. The FAA followed with AD 2022-23-10, 
Amendment 39-22237 (87 FR 73448, November 30, 2022).

Discussion of Final Airworthiness Directive

Comments

    The FAA received comments from the Air Line Pilots Association, 
International (ALPA), Boeing, and United Airlines (UAL), who supported 
the NPRM without change.
    The FAA received additional comments from Aviation Partners Boeing 
(APB), Delta Air Lines (Delta), United Parcel Service Co. (UPS 
Airlines), and Air Canada. The following presents the comments received 
on the NPRM and the FAA's response to each comment.

Effect of Winglets on Accomplishment of the Proposed Actions

    APB stated that the installation of winglets per Supplemental Type 
Certificate (STC) ST01920SE does not affect compliance with the 
proposed actions.
    The FAA agrees with the commenter. The installation of STC 
ST01920SE does not affect the ability to accomplish the actions 
required by this AD. The FAA has not changed this AD in this regard.

Request To Correct a Part Name in Boeing Service Bulletin

    Delta requested that the FAA add an exception to paragraph (h) of 
the proposed AD as follows: Where the ``Name'' column for P/N NAS43DD6-
24FC in step 5 of figure 11 and step 5 of figure 13 in Boeing Alert 
Requirements Bulletin 767-38A0076 RB, dated December 1, 2023, states 
``SPACERS FOR BOLTS,'' this AD requires using ``SPACER FOR BOLT.'' Only 
one spacer needs to be installed.
    The FAA agrees with the request. Only one spacer is to be installed 
in step 5 of figure 11 and step 5 of figure 13. The FAA has added 
paragraph (h)(2) to this AD accordingly.

Requests for Excluding Boeing Model 767-300 Bedek Special Freighters in 
Applicability

    UPS Airlines requested that the FAA add the following statement to 
this AD: ``This AD is not applicable to 767-300 airplanes listed in the 
Boeing Alert Requirements Bulletin 767-38A0076 RB, dated December 1, 
2023, that were converted by Israel Aerospace Industries (IAI) STC 
number ST02040SE to freighter configuration where the subject hoses 
were removed.'' UPS Airlines stated that it operates Boeing Model 767-
300 series airplanes converted to freighter configuration by IAI, known 
as 767-300 Bedek Special Freighter (BDSF) fleet. The potable water 
hoses indicated in the Boeing service bulletin have been removed during 
freighter conversion by IAI STC number ST02040SE to freighter 
configuration.
    Similarly, Air Canada requested that the FAA add a statement 
stating that this AD is not applicable to any Boeing Model 767-300 
passenger airplanes listed in Boeing Alert Requirements Bulletin 767-
38A0076 RB, dated December 1, 2023, that have been modified to a 767-
300BDSF configuration. Air Canada operates six Model 767-300 airplanes 
that were modified to an all-cargo configuration as per IAI STC 
ST02040SE. During this modification the water system was removed 
similar to the Boeing Model 767-300 converted freighter airplanes.
    The FAA agrees with the requests. The potable water hoses indicated 
in Boeing Alert Requirements Bulletin 767-38A0076 RB, dated December 1, 
2023, have been removed during freighter conversion by IAI STC number 
ST02040SE to freighter configuration. The FAA has revised paragraph (c) 
of this AD accordingly.

Conclusion

    The FAA reviewed the relevant data, considered any comments 
received, and

[[Page 8660]]

determined that air safety requires adopting this AD as proposed. 
Accordingly, the FAA is issuing this AD to address the unsafe condition 
on these products. Except for minor editorial changes, and any other 
changes described previously, this AD is adopted as proposed in the 
NPRM. None of the changes will increase the economic burden on any 
operator.

Material Incorporated by Reference Under 1 CFR Part 51

    The FAA reviewed Boeing Alert Requirements Bulletin 767-38A0076 RB, 
dated December 1, 2023. This material specifies procedures for the 
following actions at the lower lobe section 43 potable water system 
plumbing on the left-side:
     Installing hoseducts and support clamps.
     Installing spray shields, new tie straps on the supply 
hose, and tee fitting shrouds, depending on the airplane configuration.
     Replacing the supply hoses and tee fittings for certain 
airplane configurations.
     Doing a potable water system leakage test and, for any 
leakage found, repeating the test until no leakage is found.
    This material 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

    The FAA estimates that this AD affects 397 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                 Cost on U.S.
             Action                  Labor cost           Parts cost       Cost per product        operators
----------------------------------------------------------------------------------------------------------------

 connections, and leakage test.   hours x $85 per
                                  hour = $1,615.
----------------------------------------------------------------------------------------------------------------

    The FAA has included all known costs in its cost estimate. 
According to the manufacturer, however, some or all of the costs of 
this AD may be covered under warranty, thereby reducing the cost impact 
on affected operators.

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

    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) Will not affect intrastate aviation in Alaska, and
    (3) 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.
