SUPPLEMENTARY INFORMATION:
Comments
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,
Discussion of Final Airworthiness
Directive
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:

(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.

SUMMARY:
16:19 Aug 31, 2022
Authority for This Rulemaking
The FAA’s authority to issue rules
regarding aviation safety is found in
Title 49 of the United States Code.
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. This rulemaking is
promulgated under the authority
described in Subtitle VII, Part A,
Subpart I, Section 40103. Under that
section, the FAA is charged with
prescribing regulations to assign the use
of airspace necessary to ensure the
safety of aircraft and the efficient use of
airspace. This regulation is within the
scope of that authority as it removes the
Class E airspace extending upward from
700 feet above the surface at
Northwoods Airport, Watersmeet, MI,
due to the cancellation of the
instrument procedures at this airport,
and the airspace is no longer being
required.

SUPPLEMENTARY INFORMATION:
Jkt 256001
The FAA published a notice of
proposed rulemaking in the Federal
Register (87 FR 37252; June 22, 2022)
for Docket No. FAA–2022–0766 to
remove the Class E airspace at
Watersmeet, MI. Interested parties were
invited to participate in this rulemaking
effort by submitting written comments
on the proposal to the FAA. No
comments were received.
Class E airspace designations are
published in paragraph 6005 of FAA
Order JO 7400.11F, dated August 10,
2021, and effective September 15, 2021,
which is incorporated by reference in 14
CFR 71.1. The Class E airspace
designations listed in this document
will be published subsequently in FAA
Order JO 7400.11.
Availability and Summary of
Documents for Incorporation by
Reference
This document amends FAA Order JO
7400.11F, Airspace Designations and
Reporting Points, dated August 10,
2021, and effective September 15, 2021.
FAA Order JO 7400.11F is publicly
available as listed in the ADDRESSES
section of this document. FAA Order JO
7400.11F lists Class A, B, C, D, and E
airspace areas, air traffic service routes,
and reporting points.
This action is the result of the
instrument procedures at this airport
being cancelled and the
decommissioning of the Watersmeet
NDB, the airspace no longer being
required.
FAA Order JO 7400.11, Airspace
Designations and Reporting Points, is
published yearly and effective on
September 15.
Regulatory Notices and Analyses
The FAA has determined that this
regulation only involves an established
body of technical regulations for which
frequent and routine amendments are
necessary to keep them operationally
current, is non-controversial and
unlikely to result in adverse or negative
comments. It, therefore: (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); and (3)
does not warrant preparation of a
regulatory evaluation as the anticipated
impact is so minimal. Since this is a
routine matter that only affects air traffic
procedures and air navigation, it is
certified that this rule, when
promulgated, does not have a significant
economic impact on a substantial
number of small entities under the
criteria of the Regulatory Flexibility Act.
Environmental Review
The FAA has determined that this
action qualifies for categorical exclusion
under the National Environmental
Policy Act in accordance with FAA
Order 1050.1F, ‘‘Environmental
Impacts: Policies and Procedures,’’
paragraph 5–6.5.a. This airspace action
is not expected to cause any potentially
significant environmental impacts, and
no extraordinary circumstances exist
that warrant preparation of an
environmental assessment.

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

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

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

(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.
