RIN 2120-AA64

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) 
2016-14-04, which applies to certain The Boeing Company Model 787-8 
airplanes. AD 2016-14-04 requires replacing the potable waterline 
couplings above the forward and aft electronics equipment (EE) bays 
with new, improved couplings. AD 2016-14-04 also requires sealing the 
main cabin floor areas above the aft EE bay, installing drip shields 
and foam blocks, and rerouting the wire bundles near the drip shields 
above the equipment in the aft EE bay. Since the FAA issued AD 2016-14-
04, it was determined that sealant, moisture barrier tape and tape dam 
requirements above the EE bays may not have been installed on 
production airplanes. This proposed AD continues to require the actions 
in AD 2016-14-04 and would require an inspection of seat tracks above 
the EE bays for missing, damaged, or deteriorated sealant, moisture 
barrier tape, or tape dams, as applicable, and applicable on-condition 
actions. This proposed AD also adds airplanes to the applicability. 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 February 
10, 2025.

designated as CBI will be placed in the public docket for this 
rulemaking.

Background

    The FAA issued AD 2016-14-04, Amendment 39-18585 (81 FR 44499, July 
8, 2016) (AD 2016-14-04), for certain The Boeing Company Model 787-8 
airplanes. AD 2016-14-04 was prompted by reports of water leakage from 
the potable water system due to improperly installed waterline 
couplings, and water leaking into the EE bays from above the floor in 
the main cabin, resulting in water on the equipment in the EE bays. AD 
2016-14-04 requires replacing the potable waterline couplings above the 
forward and aft EE bays with new, improved couplings. AD 2016-14-04 
also requires sealing the main cabin floor areas above the aft EE bay, 
installing drip shields and foam blocks, and rerouting the wire bundles 
near the drip shields above the equipment in the aft EE bay. The agency 
issued AD 2016-14-04 to prevent a water leak from an improperly 
installed potable water system coupling, or main cabin water source, 
which could cause the equipment in the EE bays to become wet, resulting 
in an electrical short and potential loss of system functions essential 
for safe flight.

Actions Since AD 2016-14-04 Was Issued

    Since the FAA issued AD 2016-14-04, it was determined that sealant, 
moisture barrier tape and tape dam requirements above the EE bays may 
not have been installed on production airplanes. Missing moisture 
barrier tape, tape dams, and sealant at the end of exposed seat tracks 
above the forward and aft EE bays could allow water to leak onto 
equipment located in the EE bay(s) which could result in an electrical 
short and potential loss of several functions essential for safe 
flight.

FAA's Determination

    The FAA is issuing this NPRM after determining that the unsafe 
condition described previously is likely to exist or develop on other 
products of the same type design.

Material Incorporated by Reference Under 1 CFR Part 51

    The FAA reviewed Boeing Alert Requirements Bulletin 787-81205-
SB530085-00 RB, Issue 001, dated March 6, 2024. This material specifies 
procedures for a detailed inspection of seat tracks located above the 
aft EE bays for missing, damaged, or deteriorated sealant, moisture 
barrier tape, or tape dams, as applicable, and applicable on-condition 
actions. On-condition actions include applying sealant, moisture 
barrier tape, and tape dams to each affected area.
    The FAA also reviewed the following material:
     Boeing Alert Service Bulletin B787-81205-SB380009-00, 
Issue 003, dated April 28, 2017, which describes procedures for 
replacing the existing potable waterline couplings located above the 
forward and aft EE bays with new, improved couplings, doing a potable 
water system leak test and repairing any leaks found.
     Boeing Alert Service Bulletin B787-81205-SB530029-00, 
Issue 003, dated May 6, 2019, which describes procedures for applying 
sealant to the main cabin floor areas located above the aft EE bay.
     Boeing Alert Service Bulletin B787-81205-SB530031-00, 
Issue 003, dated April 24, 2017, which describes procedures for 
installing drip shields and foam blocks, and rerouting the wire bundles 
near the drip shields above the equipment in the aft EE bay.
    This proposed AD would also require the following material, which 
the Director of the Federal Register approved for incorporation by 
reference as of August 12, 2016 (81 FR 44499, July 8, 2016):
     Boeing Alert Service Bulletin B787-81205-SB380009-00, 
Issue 002, dated December 9, 2015.
     Boeing Alert Service Bulletin B787-81205-SB530029-00, 
Issue 002, dated January 26, 2016.
     Boeing Alert Service Bulletin B787-81205-SB530031-00, 
Issue 002, dated March 16, 2016.
    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.

Proposed AD Requirements in This NPRM

    This proposed AD would retain all requirements of AD 2016-14-04. 
This proposed AD would add certain Model 787-8, 787-9, and 787-10 
airplanes to the applicability. This proposed AD would also require 
accomplishing the

[[Page 104902]]

actions specified in the material already described, 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 
material at regulations.gov under Docket No. FAA-2024-2665.

Clarification of Affected Airplanes

    Paragraphs (g), (h)(1), and (h)(2) of AD 2016-14-04 specify doing 
actions in accordance with certain service information. However, the 
paragraphs apply to all airplanes identified in the applicability and 
did not limit the paragraphs to airplanes identified in the service 
information identified in each paragraph. Therefore, in paragraphs (g), 
(h)(1), and (h)(2) of this AD, the FAA has clarified the affected 
airplanes for each paragraph.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 64 airplanes of U.S. registry. The FAA estimates the following 
costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                 Cost on U.S.
              Action                    Labor cost        Parts cost      Cost per product        operators
----------------------------------------------------------------------------------------------------------------
Retained actions from AD 2016-14-  Up to 174 work-             $37,926  Up to $52,716......  Up to $3,373,824.
 04.                                hours x $85 per
                                    hour = up to
                                    $14,790 per
                                    inspection cycle.
Inspection of floor seat track     22 work-hours x $85               0  $1,870.............  $119,680.
 (new proposed action).             per hour = $1,870.
----------------------------------------------------------------------------------------------------------------

    The FAA estimates the following costs to do any necessary on-
condition actions that would be required based on the results of the 
proposed inspection. The agency has no way of determining the number of 
aircraft that might need this repair:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                     Cost per
                    Action                                Labor cost               Parts cost        product
----------------------------------------------------------------------------------------------------------------
Applying sealant, moisture barrier tape, or    33 work-hours x $85 per hour =             $350           $3,155
 tape dam.                                      $2,805.
----------------------------------------------------------------------------------------------------------------

    The FAA has included all known costs in its cost estimate. 
According to the manufacturer, however, some or all of the costs of 
this proposed 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

    The FAA 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) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

couplings, and water leaking into the electronics equipment (EE) 
bays from above the floor in the main cabin, resulting in water on 
the equipment in the EE bays. In addition, after AD 2016-14-04 was 
issued, it was determined that sealant, moisture barrier tape and 
tape dam requirements above the EE bays may not have been installed 
on production airplanes. A water leak from an improperly installed 
potable water system coupling, or main cabin water source, if not 
addressed, could cause the equipment in the EE bays to become wet, 
resulting in an electrical short and potential loss of system 
functions essential for safe flight.

Required for Compliance (RC), the provisions of paragraphs (m)(5)(i)
