Federal Register Volume 81, Issue 131 (July 8, 2016)

We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 airplanes. This AD was prompted by reports of water leakage from the potable water system due to improperly installed waterline 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. This AD requires replacing the potable waterline couplings above the forward and aft EE bays with new, improved couplings. This AD 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. We are issuing this AD 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.

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
The Boeing Company Model 787-8 airplanes. This AD was prompted by 
reports of water leakage from the potable water system due to 
improperly installed waterline 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. This AD requires 
replacing the potable waterline couplings above the forward and aft EE 
bays with new, improved couplings. This AD 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. We are issuing this AD 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.

DATES: This AD is effective August 12, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of August 12, 
2016.

SUPPLEMENTARY INFORMATION: 

Discussion

    We 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 787-8 airplanes. The NPRM published in the Federal Register on 
November 19, 2015 (80 FR 72393), (``the NPRM''). The NPRM 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. The NPRM proposed to require replacing the 
potable waterline couplings above the forward and aft EE bays with new, 
improved couplings. The NPRM also proposed to require 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. We are issuing this AD 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.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM and 
the FAA's response to each comment.

Support for the NPRM

    The Airline Pilots Association International stated that it concurs 
with the contents of the NPRM.
    United Airlines (UAL) stated that it supports the compliance time 
of 60 months to accomplish the actions proposed by the NPRM.

Requests To Revise Compliance Times

    Mr. Geoffrey Barrance requested that we revise the compliance times 
specified in the NPRM to before further flight. Mr. Barrance stated 
that, in view of the effect of common mode faults to nullify the safety 
design of critical avionic systems housed in the avionics bay, this 
matter needs to be treated with the greatest urgency and that the 
correction of the problem should be required with far greater urgency 
than the timescales proposed in the NPRM. Mr. Barrance stated an 
example of the automatic landing function of the automatic flight 
control system that does not and cannot take into account common mode 
faults such as water ingress into multiple line replaceable units 
(LRUs), which are present to provide functional redundancy and fault 
tolerance. Mr. Barrance stated that no probability can be assessed for 
unwanted behavior resulting from water ingress into multiple redundant 
LRUs.
    UAL requested that we extend the proposed compliance time from 24 
months to 30 months for accomplishing the actions specified in Boeing 
Alert Service Bulletin B787-81205-SB380009-00, Issue 001, dated March 
26, 2015. UAL stated that if maintenance requires an unforeseen 
disassembly of the airplane for access or to correct a test failure, a 
30-month period is required to schedule the clamp inspection and 
replacement in a heavy check.
    We do not agree to revise the compliance times required by this AD. 
In developing appropriate compliance times for this AD, we considered 
not only the safety implications, including evaluation of the hazards 
associated with water ingress into multiple redundant LRUs, but the 
manufacturer's recommendations, the availability of required parts, and 
the practical aspect of accomplishing the required actions within an 
interval of time that corresponds to typical scheduled maintenance for 
affected operators. After considering all the available information, we 
have determined that the compliance times, as proposed, represent 
appropriate intervals of time in which the required actions can be 
performed in a timely manner within the affected fleet, while still 
maintaining an adequate level of safety. Operators are always permitted 
to accomplish the requirements of an AD at a time earlier than the 
specified compliance time. Operators wanting additional time to comply 
with the requirements of an AD may request adjustments to the 
compliance time under the provisions of paragraph (k) of this AD. We 
will consider requests for an adjustment of the compliance time if data 
are submitted to substantiate that such an adjustment would provide an 
acceptable level of safety. We have not changed this AD in this regard.

Request To Use Alternative Moisture Barrier Tape

    UAL requested that we approve the use of flame retardant (FR) 
moisture barrier tapes Nitto 11611-MB polyurethane tape or BMS8-346 
Type II, Class 4 tape (3M 8657) as alternates to the BMS8-346 Type 1, 
Class 1 moisture barrier tape (Patco D9100) specified in Boeing Alert 
Service Bulletin B787 81205 SB530029-00, Issue 001, dated March 26, 
2015. UAL stated that during a supplemental type certificate test for a 
Model 737 airplane, burn testing was performed on the Patco D9100 tape 
by Zodiac Northwest Aerospace Technologies, and it failed the 12-second 
vertical test. UAL stated that, therefore, the Patco D9100 tape could 
not be certified to meet the 14 CFR 25.853 flammability requirements.
    We do not agree with UAL's request. We have contacted Boeing who 
provided evidence that BMS8-346 Type 1, Class 1 moisture barrier tape 
(Patco D9100) material passed the 12-second vertical burn test. UAL did 
not submit specific evidence to substantiate that Nitto 11611-MB 
polyurethane tape or BMS8-346 Type II, Class 4 tape (3M 8657) is 
compliant and that BMS8-346 Type 1, Class 1 moisture barrier tape 
(Patco D9100) material is non-compliant. Under the provisions of 
paragraph (k) of this AD, we will consider requests for approval of an 
alternative method of compliance (AMOC) if sufficient data are 
submitted to substantiate that alternative tapes are compliant. We have 
not changed this AD in this regard.

Requests To Use Revised Service Information

    Boeing and UAL requested that we revise the NPRM to refer to 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; and

[[Page 44501]]

Boeing Alert Service Bulletin B787-81205-SB530031-00, Issue 002, dated 
March 16, 2016.
    We agree with the commenters' requests to use the most current 
service information. We have revised this AD as described below.
     Boeing Alert Service Bulletin B787-81205-SB380009-00, 
Issue 002, dated December 9, 2015, adds notes, revises the waiting time 
in the leak test, and corrects typographical errors. We have revised 
paragraphs (c) and (g) of this AD to reference this service 
information.
     Boeing Alert Service Bulletin B787-81205-SB530029-00, 
Issue 002, dated January 26, 2016, extends the 24-month compliance time 
for sealing floor panels and seat tracks to 60 months; clarifies 
installation of components, revises tape requirements; revises sealant 
callouts; and corrects kit contents. We have revised paragraphs (c) and 
(h)(1) of this AD to reference this service information.
     Boeing Alert Service Bulletin B787-81205-SB530031-00, 
Issue 002, dated March 16, 2016, extends the 24-month compliance time 
for installing drip shields and foam blocks to 60 months. This service 
information also revises the airplane groups into configurations to 
account for airplanes on which the drip shield between the floor beams 
at station (STA) 1233 and STA 1257 was not installed due to 
interference with wire bundles over the P100 panel. This service 
information also clarifies certain instructions, revises certain task 
hour estimates, and removes one airplane from the effectivity. This 
service information erroneously specifies ``Group 6, Configuration 1'' 
airplanes where it should specify ``Group 7, Configuration 1'' 
airplanes for Task 29 in multiple places. We have revised paragraphs 
(c) and (h)(2) of this AD to reference Boeing Alert Service Bulletin 
B787-81205-SB530031-00, Issue 002, dated March 16, 2016. We have added 
new paragraph (i) to specify an exception for Boeing Alert Service 
Bulletin B787-81205-SB530031-00, Issue 002, dated March 16, 2016.
    We have also added new paragraph (j) of this AD to provide credit 
for actions done prior to the effective date of this AD using Boeing 
Alert Service Bulletin B787-81205-SB380009-00, Issue 001, dated March 
26, 2015; Boeing Alert Service Bulletin B787-81205-SB530029-00, Issue 
001, dated March 26, 2015; and Boeing Alert Service Bulletin B787-
81205-SB530031-00, Issue 001, dated March 26, 2015; as applicable. We 
have redesignated subsequent paragraphs accordingly.

Request To Review Airplane Certification Procedures

    Mr. Geoffrey Barrance requested that we conduct an internal review 
and a review with the manufacturer as to why the airplane equipment bay 
design was not reviewed and required to protect the avionics LRUs from 
water ingress at the time of certification. Mr. Barrance stated that 
this is not a new issue and must be a standard check item on design 
reviews and certification signoff. Mr. Barrance stated that this is a 
design and certification omission, not primarily a problem with the 
quality of work by the people doing the installation of the potable 
waterlines.
    We partially agree with Mr. Barrance's request. We agree that this 
is a design issue that increased the likelihood of mis-installation, 
and not primarily a problem with the quality of work by personnel 
installing the potable waterlines. We asked the manufacturer to conduct 
a root-cause analysis to determine how it permitted design issues that 
created the unsafe condition. We are working with the manufacturer to 
determine if their company processes must be updated to better identify 
these hazards. The actions required by this AD address only the results 
of that analysis that directly relate to the identified design issues, 
and mandate changes to correct those issues.
    We disagree that the EE bay design was not reviewed and required to 
protect the avionics LRUs from water ingress at the time of 
certification. A hazard analysis was completed for these systems, as 
part of the certification process, which required known hazards to be 
addressed. This event shows that despite the hazard analysis during the 
design and certification phase, further improvement is needed to remove 
the unsafe condition. Airplane manufacturers are responsible for the 
safety of their products and services, and must be in compliance with 
applicable safety requirements. As a component of our safety management 
system, we verify that the safety systems of the design approval holder 
meet applicable requirements. Working with approval holders during the 
design development process, we strive to avoid unsafe conditions in the 
first place. The design for this system was evaluated during the 
certification process and found at the time to be compliant. We also 
verify that the approval holders' processes, products, and services 
continue to maintain safety of their product during the operational 
phases of their service life. In this regard, we have evaluated the 
issues related to this system and acted on them.
    We are continuously evaluating our certification system and 
procedures and improving them when problems are found. In addition, if 
the FAA is made aware of issues occurring on a certificated product, we 
conduct an investigation, evaluate the manufacturer's root-cause 
analysis, and make a determination whether or not an unsafe condition 
exists. We then take appropriate action to mitigate the unsafe 
condition. We have not changed this AD in this regard.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this AD with the changes described previously and minor editorial 
changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all 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.
    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.

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) Is not a ``significant rule'' under 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.

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 Required for Compliance (RC), the provisions of paragraphs 
(k)(4)(i) and (k)(4)(ii) apply.
    (i) The steps labeled as RC, including substeps under an RC step

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.
