Abstract
The FAA is superseding Airworthiness Directive (AD) 2021-06- 03, which applied to all The Boeing Company Model 777F series airplanes. AD 2021-06-03 required deactivating the potable water system. This AD was prompted by a report of a water supply line that detached at a certain joint located above an electronic equipment (EE) cooling filter, leading to water intrusion into the forward EE bay. This AD retains the actions required by AD 2021-06-03 and requires installing a shroud to the water supply line in the forward cargo compartment, and performing a leak test of the potable water system. For certain airplanes, this AD also requires replacing tubes and hoses from the water supply line and installing a shroud to the water return line. The FAA is issuing this AD to address the unsafe condition on these products.

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to supersede AD 2021-06-03, Amendment 39-21469 (86 FR
12809, March 5, 2021) (AD 2021-06-03). AD 2021-06-03 applied to all The
Boeing Company Model 777F series airplanes. The NPRM published in the
Federal Register on March 25, 2022 (87 FR 17035). The NPRM was prompted
by the development of new actions that result in a need to modify AD
2021-06-03. AD 2021-06-03 was issued because of a report of a water
supply line that detached at a certain joint located above an EE
cooling filter, leading to water intrusion into the forward EE bay. In
the NPRM, the FAA proposed to continue to require deactivating the
potable water system. The NPRM also proposed to require installing a
shroud to the water supply line in the forward cargo compartment, and
performing a leak test of the potable water system. For certain
airplanes, the NPRM also proposed to require replacing tubes and hoses
from the water supply line and installing a shroud to the water return
line. The FAA is issuing this AD to address water entering the EE
cooling system via the cooling filter, which can affect multiple EE bay
racks and line replaceable units (LRUs), resulting in loss of
functionality or inaccurate output of critical electrical systems and
possible loss of control of the airplane.
Discussion of Final Airworthiness Directive
Comments
The FAA received comments from the Air Line Pilots Association,
International (ALPA), and an individual, who supported the NPRM without
change.
The FAA received additional comments from three commenters,
including Boeing, FedEx, and All Nippon Airways. The following presents
the comments received on the NPRM and the FAA's response to each
comment.
Request To Change the Affected Airplanes for Certain Requirements
FedEx and Boeing requested that the FAA change the affected
airplanes in paragraph (g)(2) of the proposed AD from ``L/Ns [line
numbers] 960 and subsequent.'' to ``L/N 960 through L/N 1689.'' FedEx
noted that the airplanes affected by paragraph (g)(2) of the proposed
AD should reflect the effectivity of Boeing Alert Requirements Bulletin
777-38A0048 RB, dated October 18, 2021. FedEx stated that if the
affected airplanes are not revised, then the final rule will require
Boeing Alert Requirements Bulletin 777-38A0048 RB, dated October 18,
2021, to be accomplished on aircraft to which it is not effective.
Boeing pointed out that the FAA has previously accepted this
alternative method of compliance (AMOC) to AD 2021-06-03 for L/N(s)
1692 and on, which have incorporated Type Design Change PRR 62701 Part
B.
The FAA agrees with the request for the reasons stated above. The
FAA has changed paragraph (g)(2) of this AD from ``L/Ns 960 and
subsequent'' to ``L/N 960 through L/N 1689 inclusive.''
Request To Change the Compliance Time of an Approved AMOC
FedEx requested that the FAA allow the AMOC to AD 2021-06-03 that
included Boeing Alert Service Bulletin 777-38A0047, dated March 30,
2021, to remain valid for 24 months from the published date of Boeing
Alert Service Bulletin 777-38A0047, dated March 30, 2021, in this AD.
FedEx reasoned that the AMOC to AD 2021-06-03 will expire earlier than
actions specified in Boeing Alert Requirements Bulletin 777-38A0048 RB,
dated October 18, 2021, can reasonably be accomplished. All Nippon
Airways requested that the AMOC to AD 2021-06-03 for Boeing Alert
Service Bulletin 777-38A0047, dated March 30, 2021, remain valid for 24
months from the effective date of this AD. All Nippon Airways contended
that if this AD does not allow Boeing Alert Service Bulletin 777-
38A0047, dated March 30, 2021, to remain valid, certain airplanes will
be grounded. All Nippon Airways also noted that if this AD continues to
allow Boeing Alert Service Bulletin 777-38A0047, dated March 30, 2021,
as an AMOC to this AD, but without extending the compliance time,
certain airplanes may be grounded due to the time needed to submit and
validate the AMOC Notice to its local authority.
Alternatively, All Nippon Airways requested that this AD be issued
after the expiration of the interim action of the AMOC to AD 2021-06-03
that includes Boeing Alert Service Bulletin 777-38A0047, dated March
30, 2021. All Nippon Airways contended that if this AD does not allow
the AMOC that specifies Boeing Alert Service Bulletin 777-38A0047,
dated March 30, 2021, to remain valid, certain airplanes will be
grounded for the reasons described above.
The FAA agrees with the intent behind the requests but cannot
change the existing AMOC to provide this relief to operators. However,
the FAA is considering issuing an amended AMOC that would extend the
compliance time of Boeing Alert Service Bulletin 777-38A0047, dated
March 30, 2021. If this amended AMOC is issued, then it may extend the
24-month compliance time to align with the compliance time of Boeing
Alert Requirements Bulletin
[[Page 73450]]
777-38A0048 RB, dated October 18, 2021. The FAA has added paragraph
(n)(4) of this AD to state that ``AMOCs approved for AD 2021-06-03 are
approved as AMOCs for the corresponding provisions of this AD.''
Additionally, the FAA does not agree to delay the issuance of this
AD until after the expiration of the interim action of the AMOC to AD
2021-06-03 that includes Boeing Alert Service Bulletin 777-38A0047,
dated March 30, 2021. An AD is issued to correct an unsafe condition.
The unsafe condition will be corrected using Boeing Alert Requirements
Bulletin 777-38A0048 RB, dated October 18, 2021. The FAA has not
changed the AD in this regard.
Request To Reference the Optional Interim Action of AD 2021-06-03
FedEx and Boeing requested that the FAA include a paragraph in this
AD that allows for an optional interim action in accordance with Boeing
Alert Service Bulletin 777-38A0047, dated March 30, 2021. FedEx and
Boeing maintained that this AD should reference Boeing Alert Service
Bulletin 777-38A0047, dated March 30, 2021, which was included in an
AMOC to AD 2021-06-03. FedEx noted that by including the interim action
of Boeing Alert Service Bulletin 777-38A0047, dated March 30, 2021, in
this final rule, the information will provide a more complete picture
of the entire timeline for future reference.
The FAA agrees for the reasons provided. The FAA has previously
approved the AMOC to AD 2021-06-03 regarding the installation of a
temporary water line shroud in accordance with Boeing Alert Service
Bulletin 777-38A0047, dated March 30, 2021. As a result, the FAA has
added paragraph (l) of this AD, which allows the activation of the
potable water system provided that installation of a shroud around the
water supply line and gray water line, installation of a shroud around
the water return line, and post-installation inspections and applicable
corrective actions are done in accordance with Boeing Alert Service
Bulletin 777-38A0047, dated March 30, 2021; and provided that the
potable water system is deactivated within a certain compliance time.
The FAA has also redesignated subsequent paragraphs accordingly. The
FAA has also revised the Costs of Compliance section to include the
cost estimates for this optional action.
Conclusion
The FAA reviewed the relevant data, considered any comments
received, and determined that air safety requires adopting this AD as
proposed. 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.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Boeing Alert Requirements Bulletin 777-38A0048 RB,
dated October 18, 2021. This service information specifies procedures
for replacing tubes and hoses from the water supply line and installing
a shroud to the water supply and return lines in the forward cargo
compartment and performing a leak test of the potable water system.
The FAA also reviewed Boeing Alert Service Bulletin 777-38A0047,
dated March 30, 2021. This service information describes procedures for
installing a shroud around the water supply line and gray water line at
station (STA) 529 to STA 634 in the forward cargo compartment,
installing a shroud around the water return line at STA 550 to STA 620
in the forward cargo compartment, post-installation inspection
requirements (which, depending on the shroud location, include a
detailed inspection for any evidence of a water leak and a general
visual inspection to determine if the shroud is in serviceable
condition), and corrective actions (which include doing applicable
corrective actions and a leak test until no leak is detected, and doing
applicable corrective actions to put the shroud back to serviceable
condition).
This AD also requires Boeing Multi Operator Message MOM-MOM-21-
0089-01B, dated February 26, 2021, which the Director of the Federal
Register approved for incorporation by reference as of March 5, 2021
(86 FR 12809, March 5, 2021).
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 ADDRESSES.
Costs of Compliance

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
[[Page 73451]]
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.
