The FAA is superseding
Airworthiness Directive (AD) 2015–12–
03, which applied to certain The Boeing
Company Model 777–200, –200LR,
–300, and –300ER series airplanes. AD
2015–12–03 required repetitive freeplay
inspections and lubrication of the right
and left elevators, rudder, and rudder
tab, and related investigative and
corrective actions if necessary. This AD
was prompted by engineering testing
which revealed that the force being
applied to the elevator to detect
excessive freeplay was insufficient. This
AD continues to require certain actions
in AD 2015–12–03 for certain airplanes,
and requires revising the existing
maintenance or inspection program, as
applicable, for certain other airplanes, to
incorporate a revised or new elevator
freeplay maintenance procedure, as
applicable. This AD also adds airplanes
to the applicability. The FAA is issuing
this AD to address the unsafe condition
on these products.
DATES: This AD is effective October 12,
2022.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in this AD
as of October 12, 2022.
The Director of the Federal Register

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2015–12–03,
Amendment 39–18176 (80 FR 34252,
June 16, 2015) (AD 2015–12–03). AD
2015–12–03 applied to certain The
Boeing Company Model 777–200,
–200LR, –300, and –300ER series
airplanes. The NPRM published in the
Federal Register on March 24, 2022 (87
FR 16654). The NPRM was prompted by
the manufacturer’s determination that
the procedure for the rudder freeplay
inspection available at the time did not
properly detect excessive freeplay in the
rudder control load loop. The NPRM
was also prompted by engineering
testing which revealed that the force
being applied to the elevator to detect
excessive freeplay was insufficient. In
the NPRM, the FAA proposed to
continue to require certain actions in
AD 2015–12–03 for certain airplanes,
and to require revising the existing
maintenance or inspection program, as
applicable, for certain other airplanes, to
incorporate a revised or new elevator

freeplay maintenance procedure, as
applicable. The NPRM also proposed to
add airplanes to the applicability. The
FAA is issuing this AD to address
excessive wear in the load loop
components of the control surfaces,
which could lead to excessive freeplay
of the control surfaces, flutter, and
consequent loss of control of the
airplane.
Discussion of Final Airworthiness
Directive
Comments
The FAA received comments from
The Air Line Pilots Association,
International (ALPA) and Boeing, who
supported the NPRM without change.
The FAA received additional
comments from United Airlines. The
following presents the comments
received on the NPRM and the FAA’s
response.
Request for Exception To Correct
Service Information Typographical
Error
United Airlines (UAL) asked that the
FAA consider including an exception in
paragraph (i) of the proposed AD due to
a typographical error in Boeing Special
Attention Service Bulletin 777–27–
0062, Revision 4, dated July 15, 2021.
UAL stated that it identified a
typographical error in Appendix A,
paragraph 1.f., ‘‘Freeplay Inspection,’’ in
the CAUTION note just before step (6).
UAL added that the note shows the
conversion of 84 square inches as 5,420
square centimeters; however, 84 square
inches calculates to 542 square
centimeters.
The FAA agrees that Appendix A of
the referenced service information
contains a typographical error, as
described by the commenter. Therefore,
that FAA has added an exception to
paragraph (i)(5) of this AD which states
that where Appendix A, paragraph 1.f.,
‘‘Freeplay Inspection,’’ of Boeing
Special Attention Service Bulletin 777–
27–0062, Revision 4, dated July 15,
2021, specifies to use a pad that
distributes the force over an area of 84
square inches (5,420 square centimeters)
or more, this AD requires using a pad
that distributes the force over an area of
84 square inches (542 square
centimeters) or more. The FAA also
revised the introductory text to
paragraph (i)(5) to specify that a new
exception has been added.
Conclusion
The FAA reviewed the relevant data,
considered any comments received, and
determined that air safety requires
adopting this AD as proposed. Except
for minor editorial changes, and any
other change described previously, this
AD is adopted as proposed in the
NPRM. None of the changes will
increase the economic burden on any
operator.
Related Service Information Under 1
CFR Part 51
The FAA reviewed Boeing Special
Attention Service Bulletin 777–27–
0062, Revision 4, dated July 15, 2021.
This service information specifies
procedures for changing the elevator
freeplay instructions by adding changes
to the input force, elevator freeplay
limit, and power control unit (PCU)
bypass test setup.
This AD also requires Boeing Special
Attention Service Bulletin 777–27–
0062, Revision 2, dated January 27,
2014, which the Director of the Federal
Register approved for incorporation by
reference as of July 21, 2015 (80 FR
34252, June 16, 2015).
This service information is reasonably
available because the interested parties
have access to it through their normal
course of business or by the means
identified in ADDRESSES.
Costs of Compliance
The FAA estimates that this AD
affects 281 airplanes of U.S. registry.
The FAA estimates the following costs
to comply with this AD:
ESTIMATED COSTS

Labor cost
Measurement (inspection), elevator.
4 work-hours × $85 per hour
= $340 per measurement

The FAA has received no definitive
data that would enable the agency to
provide cost estimates for the oncondition corrective actions specified in
this AD.
The FAA has determined that revising
the existing maintenance or inspection
program takes an average of 90 workhours per operator, although the agency
recognizes that this number may vary
from operator to operator. Since

operators incorporate maintenance or
inspection program changes for their
affected fleet(s), the FAA has
determined that a per-operator estimate
is more accurate than a per-airplane
estimate. Therefore, the FAA estimates
the average total cost per Model 777F
operator to be $7,650 (90 work-hours ×
$85 per work-hour).

ACTION: Final rule.
AGENCY:
Background
The FAA is adopting a new
airworthiness directive (AD) for certain
General Electric Company (GE) GEnx–
1B model turbofan engines. This AD
was prompted by several reports of fuel
leaks caused by high cycle fatigue (HCF)
cracks found at the braze joints on fuel
manifolds, and the subsequent
manufacturer redesign of the highpressure turbine (HPT) fuel hose
variable stator vane (VSV) manifold,
VSV fuel hose manifold, low-pressure
turbine (LPT) fuel hose variable bleed
valve (VBV) manifold, and VBV fuel
hose manifold. This AD requires
removal and replacement of the fuel
hydraulic lines. The FAA is issuing this
AD to address the unsafe condition on
these products.

Examining the AD Docket
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to certain GE GEnx–1B model
turbofan engines. The NPRM published
in the Federal Register on June 3, 2022
(87 FR 33658). The NPRM was
prompted by several reports of fuel
manifold leaks resulting in multiple
flight delays and cancellations on four
separate occasions between 2018 and
2021 on airplanes with GEnx–1B model
turbofan engines installed. The
manufacturer’s investigation revealed
that variations in braze coverage and
braze fillet radii caused high stress
concentration factors at the braze block
joints, leading to HCF failure in the tube
bundles with brazed joints. As a result
of its investigation, the manufacturer
determined that the HPT fuel hose VSV
manifold, VSV fuel hose manifold, LPT
fuel hose VBV manifold, and VBV fuel
hose manifold required redesign by
replacing all braze features and
cushioned clamps with block clamps. In
the NPRM, the FAA proposed to require
the removal and replacement of the fuel
hydraulic lines. The FAA is issuing this

-----------------------------------------------------------------------
SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2015-12-
03, which applied to certain The Boeing Company Model 777-200, -200LR,
-300, and -300ER series airplanes. AD 2015-12-03 required repetitive
freeplay inspections and lubrication of the right and left elevators,
rudder, and rudder tab, and related investigative and corrective
actions if necessary. This AD was prompted by engineering testing which
revealed that the force being applied to the elevator to detect
excessive freeplay was insufficient. This AD continues to require
certain actions in AD 2015-12-03 for certain airplanes, and requires
revising the existing maintenance or inspection program, as applicable,
for certain other airplanes, to incorporate a revised or new elevator
freeplay maintenance procedure, as applicable. This AD also adds
airplanes to the applicability. The FAA is issuing this AD to address
the unsafe condition on these products.

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to supersede AD 2015-12-03, Amendment 39-18176 (80 FR
34252, June 16, 2015) (AD 2015-12-03). AD 2015-12-03 applied to certain
The Boeing Company Model 777-200, -200LR, -300, and -300ER series
airplanes. The NPRM published in the Federal Register on March 24, 2022
(87 FR 16654). The NPRM was prompted by the manufacturer's
determination that the procedure for the rudder freeplay inspection
available at the time did not properly detect excessive freeplay in the
rudder control load loop. The NPRM was also prompted by engineering
testing which revealed that the force being applied to the elevator to
detect excessive freeplay was insufficient. In the NPRM, the FAA
proposed to continue to require certain actions in AD 2015-12-03 for
certain airplanes, and to require revising the existing maintenance or
inspection program, as applicable, for certain other airplanes, to
incorporate a revised or new elevator
[[Page 54610]]
freeplay maintenance procedure, as applicable. The NPRM also proposed
to add airplanes to the applicability. The FAA is issuing this AD to
address excessive wear in the load loop components of the control
surfaces, which could lead to excessive freeplay of the control
surfaces, flutter, and consequent loss of control of the airplane.
Discussion of Final Airworthiness Directive
Comments
The FAA received comments from The Air Line Pilots Association,
International (ALPA) and Boeing, who supported the NPRM without change.
The FAA received additional comments from United Airlines. The
following presents the comments received on the NPRM and the FAA's
response.
Request for Exception To Correct Service Information Typographical
Error
United Airlines (UAL) asked that the FAA consider including an
exception in paragraph (i) of the proposed AD due to a typographical
error in Boeing Special Attention Service Bulletin 777-27-0062,
Revision 4, dated July 15, 2021. UAL stated that it identified a
typographical error in Appendix A, paragraph 1.f., ``Freeplay
Inspection,'' in the CAUTION note just before step (6). UAL added that
the note shows the conversion of 84 square inches as 5,420 square
centimeters; however, 84 square inches calculates to 542 square
centimeters.
The FAA agrees that Appendix A of the referenced service
information contains a typographical error, as described by the
commenter. Therefore, that FAA has added an exception to paragraph
(i)(5) of this AD which states that where Appendix A, paragraph 1.f.,
``Freeplay Inspection,'' of Boeing Special Attention Service Bulletin
777-27-0062, Revision 4, dated July 15, 2021, specifies to use a pad
that distributes the force over an area of 84 square inches (5,420
square centimeters) or more, this AD requires using a pad that
distributes the force over an area of 84 square inches (542 square
centimeters) or more. The FAA also revised the introductory text to
paragraph (i)(5) to specify that a new exception has been added.
Conclusion
The FAA reviewed the relevant data, considered any comments
received, and determined that air safety requires adopting this AD as
proposed. Except for minor editorial changes, and any other change
described previously, this AD is adopted as proposed in the NPRM. None
of the changes will increase the economic burden on any operator.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Boeing Special Attention Service Bulletin 777-27-
0062, Revision 4, dated July 15, 2021. This service information
specifies procedures for changing the elevator freeplay instructions by
adding changes to the input force, elevator freeplay limit, and power
control unit (PCU) bypass test setup.
This AD also requires Boeing Special Attention Service Bulletin
777-27-0062, Revision 2, dated January 27, 2014, which the Director of
the Federal Register approved for incorporation by reference as of July
21, 2015 (80 FR 34252, June 16, 2015).
This service information is reasonably available because the
interested parties have access to it through their normal course of
business or by the means identified in ADDRESSES.
Costs of Compliance
The FAA estimates that this AD affects 281 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:

----------------------------------------------------------------------------------------------------------------
The FAA has received no definitive data that would enable the
agency to provide cost estimates for the on-condition corrective
actions specified in this AD.
The FAA has determined that revising the existing maintenance or
inspection program takes an average of 90 work-hours per operator,
although the agency recognizes that this number may vary from operator
to operator. Since operators incorporate maintenance or inspection
program changes for their affected fleet(s), the FAA has determined
that a per-operator estimate is more accurate than a per-airplane
estimate. Therefore, the FAA estimates the average total cost per Model
777F operator to be $7,650 (90 work-hours x $85 per work-hour).
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
[[Page 54611]]
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.
