AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all
The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This AD
was prompted by a report of heat damage on multiple engine inlets
around the engine anti-ice (EAI) duct within the inlet aft compartment.
This AD requires doing a records check and updating the operator's
existing minimum equipment list (MEL), inspecting the left and right
engine inlet cowl assembly for signs of heat damage around the EAI
duct, installing or replacing the EAI duct seals, repairing any damage,
and replacing the engine inlet if necessary. This AD also prohibits the
installation of engine inlets under certain conditions. The FAA is
issuing this AD to address the unsafe condition on these products.
DATES: This AD is effective September 24, 2024.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of September 24,
2024.

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 all The Boeing Company
(Boeing) Model 787-8, 787-9, and 787-10 airplanes. The NPRM published
in the Federal Register on February 20, 2024 (89 FR 12785). The NPRM
was prompted by a report of heat damage on multiple engine inlets
around the EAI duct within the inlet aft compartment. A subsequent
investigation found that the seals between the inner and outer ducts
and between the outer duct and the aft compartment were degraded or
missing, which led to EAI air leaking into the aft compartment,
exposing inlet components to high temperatures.
In the NPRM, the FAA proposed to require doing a records check and
updating the operator's existing MEL, inspecting the left and right
engine inlet cowl assembly for signs of heat damage around the EAI
duct, installing or replacing the EAI duct seals, repairing any damage,
and replacing the engine inlet if necessary. The FAA is issuing this AD
to address reduced structural strength and departure of the inlet from
the airplane, resulting in subsequent loss of continued safe flight and
landing or injury to occupants from a departed inlet contacting the
airplane.
Discussion of Final Airworthiness Directive
Comments
The FAA received comments from nine commenters. The commenters were
the Air Line Pilots Association, International (ALPA), American
Airlines (AAL), Boeing, British Airways, Qantas, United Airlines (UAL),
and three individual commenters.
ALPA and two individuals supported the NPRM without change.
One commenter expressed concern about the effect on safety of
certain internal Boeing practices. This comment is outside the scope of
the NPRM.
The following presents the remaining comments received on the NPRM
and the FAA's response to each comment.
Request for Additional Definition of a Serviceable Engine Inlet
In the NPRM, the FAA proposed to require complying with Boeing
Alert Requirements Bulletin B787-81205-SB540023-00 RB, Issue 001, dated
September 22, 2023, or B787-81205-SB540024-00 RB, Issue 001, dated
September 22, 2023, both of which specify replacing the engine inlet
with a new or serviceable engine inlet under certain conditions. The
requirements bulletins define a serviceable engine inlet as an engine
inlet that has been inspected and had applicable corrective actions
done in accordance with the requirements bulletins. AAL requested that
the FAA consider, as an alternative serviceable engine inlet, one that
has been inspected and had applicable corrective actions done in
accordance with Collins Service Bulletin 787-G71-013, Revision 00,
dated August 3, 2023, or later approved revisions.
The FAA does not agree. The instructions in Collins Aerospace
Service Bulletin 787-G71-013 or 787-R71-034 are insufficient to ensure
a damaged engine inlet is restored to a serviceable condition. Where
indications of heat damage are discovered on metallic components, the
Collins service bulletins specify performing conductivity and hardness
tests. When the results of the conductivity or hardness test are
outside acceptable limits, the Collins service bulletins specify
submitting the test results to Collins with no further
[[Page 67258]]
procedures or instructions to accomplish a repair. The FAA has not
changed this AD in this regard.
Request for Inspection Instructions in the AD
In the NPRM, the FAA proposed to require complying with Boeing
Alert Requirements Bulletin B787-81205-SB540023-00 RB, Issue 001, dated
September 22, 2023, or B787-81205-SB540024-00 RB, Issue 001, dated
September 22, 2023, both of which specify inspecting the engine inlet
cavity in accordance with those requirements bulletins and with Collins
Service Bulletin 787-G71-013 or 787-R71-034, both dated August 3, 2023,
or later-approved revisions. AAL requested that the FAA revise the AD
by adding the inspection procedures from the Boeing and Collins
bulletins instead of incorporating those procedures by reference. As
support for its request, AAL stated the bulletins are not readily
available and accessible to the line mechanics.
The FAA disagrees with AAL's request to revise the proposed AD to
include the inspection instructions instead of incorporating the
service information by reference. Including all inspection instructions
in the AD is inefficient and defeats the purpose of incorporation by
reference. The referenced Boeing and Collins service bulletins are
readily available to operators through their normal courses of business
or from the manufacturers. The FAA has not changed this AD in this
regard.
Request for Later-Approved Revisions of Structural Repair Manual
In the NPRM, the FAA proposed to require complying with Boeing
Requirements Bulletin B787-81205-SB540023-00 RB, Issue 001, dated
September 22, 2023, or B787-81205-SB540024-00 RB, Issue 001, dated
September 22, 2023, both of which reference specific sections, by
revision number, of the Boeing structural repair manual (SRM) for
certain information. Boeing and UAL requested that the FAA revise the
proposed AD to allow the use of later-approved revisions of the SRM.
Boeing stated that operators do not recall historical SRM revisions,
and therefore they can incorporate only the latest revision of the SRM
at the time of accomplishment.
The FAA disagrees with the request. The SRM sections cited in the
requirements bulletins define heat damage in a way that the FAA finds
will address the unsafe condition in this AD. If future revisions of
those SRM sections also define heat damage in a way that adequately
addresses the unsafe condition in this AD, the commenters can request
approval of those sections as an alternative method of compliance
(AMOC). The FAA has not changed this AD as a result of this comment.
Request for Change to Background and Unsafe Condition
Boeing requested that the FAA revise the Background section of the
NPRM and paragraph (e) of the proposed AD to clarify that partially
degraded seals were found in addition to missing seals.
The FAA agrees and has revised the preamble and the unsafe
condition statement in paragraph (e) of this AD accordingly.
Request for Clarification of Description of Proposed Requirements
The preamble of the NPRM explained that the FAA proposed to require
doing a records check and updating the operator's MEL, among other
actions. Boeing requested that the FAA revise the preamble to clarify
that the update is actually within the Dispatch Deviations Guide (DDG)
and not with any actual equipment on the list. Boeing stated that this
change would avoid confusion regarding the actual MEL changes.
The FAA disagrees with the request. This AD requires revising the
operator's MEL by incorporating the DDG update. Although the commenter
is correct that the MEL revision is not intended to change any
equipment listed on the MEL, since the DDG is part of the MEL, the
statement in the NPRM is accurate. The FAA has not changed this AD in
this regard.
Request for Corrected Paragraph Reference
Boeing, AAL, and UAL requested that the FAA revise paragraph (h)(3)
of the proposed AD, which incorrectly referred to paragraph (k) for
approval of AMOCs. The correct reference is paragraph (j).
The FAA agrees and has revised paragraph (h) of this AD
accordingly.
Request To Extend Compliance Time for Inspection
In the NPRM, the FAA proposed to require complying with Boeing
Requirements Bulletin B787-81205-SB540023-00 RB, Issue 001, dated
September 22, 2023, or B787-81205-SB540024-00 RB, Issue 001, dated
September 22, 2023. Table 10 of the requirements bulletins specifies
doing an inspection of the engine inlet cavity at or prior to the
expiration of the time interval under MEL 30-21-01-02 or MEL 30-21-01-
07 (the interval for repair category C, which is 10 consecutive
calendar days (240 hours) with a single extension, if authorized, as
defined in the DDG).
British Airways requested that the FAA revise the compliance time
to allow an additional 125 days after the expiration of the MEL
interval period to do the inspections and any corrective actions.
British Airways acknowledged the safety concerns surrounding inlets
that have been exposed to high temperatures during the time period
allowed under MEL 30-21-01-02 or MEL 30-21-01-07 but stated the
compliance time in the NPRM would cause considerable maintenance
concerns for operators as it does not give sufficient time to plan for
and carry out the required actions in a controlled environment.
The FAA disagrees with the request for a longer compliance time.
The FAA anticipates the potential structural damage incurred by the
airplane due to dispatch under the MEL to increase as the engine inlet
accumulates more operational time under those specific MEL conditions.
Since accumulated structural damage on each engine inlet is unknown,
the FAA determined that the inspection of the engine inlet at the
completion of the dispatch interval period was necessary. Operators who
can justify that, after completion of the MEL dispatch interval period,
an engine inlet can maintain its structural integrity over a longer
time period may propose that time period as an alternative method of
compliance under the process specified in paragraph (j) of this AD.
Request To Change Location of MEL Inspection Procedure
In the NPRM, the FAA proposed to require complying with Boeing
Requirements Bulletin B787-81205-SB540023-00 RB, Issue 001, dated
September 22, 2023, or B787-81205-SB540024-00 RB, Issue 001, dated
September 22, 2023, both of which specify revising the operator's MEL
by incorporating the DDG 30-21-01-02 update. The MEL, with the DDG
update incorporated, allows dispatch with inoperative equipment
specified under items 30-21-01-02 and 30-21-01-07 provided the engine
inlet cavity is inspected and applicable corrective actions are taken
in accordance with the requirements bulletins and with Collins Service
Bulletin 787-G71-013 or 787-R71-034, both dated August 3, 2023, or
later approved revisions.
Qantas and UAL requested that the FAA change the location of the
required inspection instructions for dispatch under the MEL from the
bulletins to the airplane maintenance manual (AMM).
[[Page 67259]]
Alternatively, UAL requested that the inspection instructions be
included in the DDG update itself instead of having the DDG refer to
the service bulletins. Qantas, UAL, and British Airways all stated that
operators' maintenance systems are not set up to provide maintenance
personnel with access to service bulletins. Qantas expressed a concern
that maintenance personnel could inadvertently fail to carry out the
required inspection as part of the MEL process.
The FAA disagrees. The concern about accessibility of the
requirements bulletins to maintenance personnel is not unique to this
AD. The FAA commonly issues ADs that mandate service documents
containing instructions that must be carried out to resolve an unsafe
condition. Operators and repair stations are required to provide those
mandatory service documents to their maintenance personnel. In
addition, for this AD, the requirement through the MEL is necessary
because compliance may be based on the need for dispatch with
inoperative equipment. The FAA has not changed this AD as a result of
these comments.
Request for Instructions for Engine Inlets With Unknown History
Qantas requested that the FAA clarify how to comply with the AD for
engine inlets that are not installed on an airplane and for which the
last installation is unknown. Qantas stated that since engine inlets
can be moved from airplane to airplane, operators may not know whether
an engine inlet was installed on airplane and dispatched under the MEL.
The requirements bulletins specify that, if an operator cannot
determine whether the airplane was dispatched under MEL 30-21-01-02 or
MEL 30-21-01-07, the engine inlet must be inspected or replaced. No
change to this AD is necessary as a result of this comment.
Request for Information To Determine Heat Damage of Primer
UAL stated that the SRM sections referenced in the requirements
bulletins do not provide pass/fail criteria for the amount of
discoloration when assessing for heat damage. UAL requested
clarification of whether any browning of primer would be an indication
of a missing seal.
The commenter is correct that the SRM sections referenced in the
requirements bulletins do not provide pass/fail criteria. However, the
SRM sections do provide appropriate information to determine heat
damage. Under the criteria in the SRM, the FAA expects that any
discoloration of primer would be treated as evidence of heat damage.
The FAA has not changed this AD as a result of this comment.
Conclusion
The FAA reviewed the relevant data, considered any comments
received, and 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. 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 B787-81205-
SB540023-00 RB, Issue 001, dated September 22, 2023; and Boeing Alert
Requirements Bulletin B787-81205-SB540024-00 RB, Issue 001, dated
September 22, 2023. This material specifies procedures for
incorporating (or verifying incorporation of) an updated DDG for item
30-21-01-02 into the operator's existing MEL, checking records to
determine whether the inlet has been dispatched under MEL item 30-21-
01-02 or 30-21-01-07 before incorporation of the DDG 30-21-01-02
update, and applicable related investigative and corrective actions,
including general visual inspection for signs of heat damage around the
EAI duct, conductivity measurement and hardness test of areas with heat
damage, replacement/installation of the periseal and aft seal, and
repair or replacement of the engine inlet. These documents are distinct
since they apply to different airplane configurations. 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
ADDRESSES.
Interim Action
The FAA considers that this AD would be an interim action. An
investigation is ongoing. If final action is later identified, the FAA
might consider further rulemaking then.
Costs of Compliance
The FAA estimates that this AD affects 110 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
MEL update and records check........ 5 work-hours x $85 per $0 $425 $46,750
hour = $425.
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any investigative
actions or repairs/replacements that would be required based on the
results of the records check. The agency has no way of determining the
number of airplanes that might need these actions:
On-Condition Costs
----------------------------------------------------------------------------------------------------------------
Cost per
Action Labor cost Parts cost product
----------------------------------------------------------------------------------------------------------------
Inspection................................ 3 work-hours x $85 per hour = $255 $0 $255
----------------------------------------------------------------------------------------------------------------
The FAA has received no definitive data on which to base the cost
estimates for the conductivity measurement, the hardness test, inlet
replacement, and installation of a new periseal and aft seal, as
specified in this AD.
[[Page 67260]]
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.

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 adding the following new airworthiness
directive:
2024-13-05 The Boeing Company: Amendment 39-22779; Docket No. FAA-
2024-0231; Project Identifier AD-2023-01037-T.
(a) Effective Date
This airworthiness directive (AD) is effective September 24,
2024.
(b) Affected ADs
None.
(c) Applicability
This AD applies to all The Boeing Company Model 787-8, 787-9,
and 787-10 airplanes, certificated in any category.
(d) Subject

pylons.
(e) Unsafe Condition
This AD was prompted by a report of heat damage on multiple
engine inlets around the engine anti-ice (EAI) duct within the inlet
aft compartment due to missing or degraded seals between the inner
and outer ducts and between the outer duct and the aft compartment.
The FAA is issuing this AD to address EAI air leaking into aft
compartment exposing inlet components to high temperatures, which
could result in damage around the EAI duct. This condition, if not
addressed, could lead to reduced structural strength and departure
of the inlet from the airplane, resulting in subsequent loss of
continued safe flight and landing or injury to occupants from a
departed inlet contacting the airplane.
(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 the ``Compliance'' paragraph of Boeing
