Abstract
The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This AD was prompted by a report from Boeing that Rolls-Royce Deutschland Ltd & Co KG (RRD) discovered a design issue in the engine fuel feed system, which could result in fuel flow restrictions to both engines when ice that has accumulated in the airplane fuel feed system suddenly releases into the engines. This AD requires revising the existing airplane flight manual (AFM) to update the limitations on minimum fuel temperatures. The FAA is issuing this AD to address the unsafe condition on these products.

Airworthiness Directives; The Boeing Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes.
This AD was prompted by a report from Boeing that Rolls-Royce
Deutschland Ltd & Co KG (RRD) discovered a design issue in the engine
fuel feed system, which could result in fuel flow restrictions to both
engines when ice that has accumulated in the airplane fuel feed system
suddenly releases into the engines. This AD requires revising the
existing airplane flight manual (AFM) to update the limitations on
minimum fuel temperatures. The FAA is issuing this AD to address the
unsafe condition on these products.
DATES: This AD is effective October 6, 2022.

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 787-8, 787-9, and 787-10 airplanes. The NPRM published in
the Federal Register on April 14, 2022 (87 FR 22158). The NPRM was
prompted by a report from Boeing that RRD discovered a design issue in
the engine fuel feed system, which could result in fuel flow
restrictions to both engines when ice that has accumulated in the
airplane fuel feed system suddenly releases into the engines. In the
NPRM, the FAA proposed to require revising the existing AFM to update
the limitations on minimum fuel temperatures. The FAA is issuing this
AD to address possible fuel flow restrictions to both engines, which
could result in loss of dual engine thrust control and reduced
controllability of the airplane.
Discussion of Final Airworthiness Directive
Comments
The FAA received no comments on the NPRM or on the determination of
the cost to the public.
Conclusion
The FAA reviewed the relevant data and determined that air safety
requires adopting this AD as proposed. Except for minor editorial
changes, this AD is adopted as proposed in the NPRM. None of the
changes will increase the economic burden on any operator.
Interim Action
The FAA considers this AD interim action. Boeing is currently
working with RRD to develop updated electronic engine control (EEC)
software, which will change the engine oil temperature amber line
indicated in the engine indication and crew alerting system (EICAS).
This change will ensure that, before takeoff, the engine oil
temperature would be warm enough to operate the engine with cold fuel.
The updated EEC software combined with the action required by this AD
will address the unsafe condition identified in this AD. Once this
software is developed, approved, and available, the FAA might consider
additional rulemaking.
Costs of Compliance
The FAA estimates that this AD affects 14 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:

----------------------------------------------------------------------------------------------------------------
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
[[Page 53655]]
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.

engines installed.
(d) Subject
Air Transport Association (ATA) of America Code 28, Fuel.
(e) Unsafe Condition
This AD was prompted by a report from Boeing that Rolls-Royce
Deutschland Ltd & Co KG discovered a design issue in the engine fuel
feed system, which could result in fuel flow restrictions to both
engines when ice that has accumulated in the airplane fuel feed
system suddenly releases into the engines. The sudden release of
accumulated ice into the engine fuel feed system, in combination
with low fuel temperatures, could cause freezing temperatures at the
inlet of certain engine fuel feed system components. The FAA is
issuing this AD to address possible fuel flow restrictions to both
engines, which could result in loss of dual engine thrust control
and reduced controllability of the airplane.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Airplane Flight Manual (AFM) Revision
Within 30 days after the effective date of this AD, revise the
existing AFM to incorporate the information specified in figure 1 to
paragraph (g) of this AD into the ``Certificate Limitations''
chapter of the applicable Engine Appendix of the existing AFM.

(h) Alternative Methods of Compliance (AMOCs)
(1) The Manager, Seattle ACO Branch, FAA, has the authority to
approve AMOCs for this AD, if requested using the procedures found
in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request
to your principal inspector or responsible Flight Standards Office,
as appropriate. If sending information directly to the manager of
the certification office, send it to the attention of the person
identified in paragraph (i) of this AD. Information may be emailed
to: <a href="/cdn-cgi/l/email-protection#e4ddc9a5aaa9b7818590908881c9a5a7abc9a5a9aba7c9b681959181979097a4828585ca838b92"><span class="__cf_email__" data-cfemail="87beaac6c9cad4e2e6f3f3ebe2aac6c4c8aac6cac8c4aad5e2f6f2e2f4f3f4c7e1e6e6a9e0e8f1">[email protected]</span></a>.
(2) Before using any approved AMOC, notify your appropriate
principal inspector, or lacking a principal inspector, the manager
of the responsible Flight Standards Office.
(3) An AMOC that provides an acceptable level of safety may be
used for any repair, modification, or alteration required by this AD
if it is approved by The Boeing Company Organization Designation
Authorization (ODA) that has been authorized by the
[[Page 53656]]
Manager, Seattle ACO Branch, FAA, to make those findings. To be
approved, the repair method, modification deviation, or alteration
deviation must meet the certification basis of the airplane, and the
approval must specifically refer to this AD.
