ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2019-22-
05, which applied to all General Electric Company (GE) CF34-8C model
turbofan engines. AD 2019-22-05 required initial and repetitive
inspections of the operability bleed valve (OBV) fuel tubes, OBV bleed
air manifold link rod assemblies, and the OBV fuel fittings. AD 2019-
22-05 also required replacement of OBVs or related OBV link rod
hardware that fail inspection. This AD was prompted by multiple reports
of fuel leaks, some leading to engine fires, which have occurred as a
result of malfunctions related to the OBV. Additionally, the
manufacturer has redesigned the OBV, which terminates the need for the
repetitive inspections. This AD requires initial and repetitive
inspections of the OBV fuel tubes, OBV bleed air manifold link rod
assemblies, and the OBV fuel fittings installed on GE CF34-8C model
turbofan engines. This AD requires replacement of OBVs or related OBV
link rod hardware that fail inspection. As a terminating action to the
repetitive inspections, this AD requires replacement of certain OBVs
installed on GE CF34-8C model turbofan engines. This AD also requires
replacement of certain OBVs installed on GE CF34-8E model turbofan
engines. 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 2019-22-05, Amendment 39-19784 (84 FR
63569, November 18, 2019), (AD 2019-22-05). AD 2019-22-05 applied to
all GE CF34-8C1, CF34-8C5, CF34-8C5A1, CF34-8C5B1, CF34-8C5A2, and
CF34-8C5A3 (CF34-8C) model turbofan engines. The NPRM published in the
Federal Register on December 29, 2021 (86 FR 73997). The NPRM was
prompted by multiple reports of fuel leaks, some leading to engine
fires, which have occurred as a result of malfunctions related to the
OBV. Since the FAA issued AD 2019-22-05, the manufacturer redesigned
the OBV, which terminates the need for the repetitive inspections of
the OBV fuel tubes, OBV bleed air manifold link rod assemblies, and the
OBV fuel fittings. Additionally, the FAA determined that GE CF34-8E2,
CF34-8E2A1, CF34-8E5, CF34-8E5A1, CF34-8E5A2, CF34-8E6, and CF34-8E6A1
(CF34-8E) model turbofan engines are susceptible to the same unsafe
condition as the CF34-8C model turbofan engines, and therefore, added
the GE CF34-8E model turbofan engines to the applicability of this AD.
GE published service information specifying procedures to replace
certain OBVs installed on GE CF34-8C and CF34-8E model turbofan
engines. In the NPRM, the FAA proposed to continue to require initial
and repetitive inspections of the OBV fuel tubes, OBV bleed air
manifold link rod assemblies, the OBV fuel fittings installed on GE
CF34-8C model turbofan engines, and replacement of OBVs or related OBV
link rod hardware that fail inspection. In the NPRM, the FAA proposed
to require replacement of certain OBVs installed on GE CF34-8C model
turbofan engines as a terminating action to the repetitive inspections.
In the NPRM, the FAA also proposed to require replacement of certain
OBVs installed on GE CF34-8E model turbofan engines. The FAA is issuing
this AD to address the unsafe condition on these products.
Discussion of Final Airworthiness Directive
Comments
The FAA received comments from four commenters. The commenters were
Air Line Pilots Association, International (ALPA), Horizon Air, Japan
Airlines (JAL), and SkyWest Airlines, Inc. (SkyWest). The following
presents the comments received on the NPRM and the FAA's response to
each comment.
Request To Add Guidance for OBVs With Unknown Flight Hours (FHs) Since
New
Horizon Air requested that the FAA provide guidance for compliance
with the Required Actions, paragraphs (g)(4) and (5), in the event the
FHs since new of the OBV is unknown. Horizon Air commented that
paragraphs (g)(4) and (5) of the NPRM would require replacement of the
OBV with a part eligible for installation within prescribed periods,
which are predicated on the FHs since new of the OBV. Horizon Air
reasoned that the NPRM does not include guidance for replacing an OBV
if the FHs since new of the OBV is unknown.
In response to this comment, the FAA has added paragraph (g)(6) to
this AD, allowing use of the FHs since new of the engine if the
accumulated FHs since new of the OBV is unknown.
[[Page 30795]]
Request To Clarify the Reference Date for OBV FHs Since New
JAL requested that the FAA update paragraph (g)(4) of this AD to
include a reference date for OBV FHs since new. JAL noted that although
paragraph (g)(4) of the NPRM has the OBV FHs since new, it does not
provide a reference date.
The FAA revised paragraphs (g)(4)(i) through (iii) of this AD to
identify the reference date as requested by the commenter.
Request To Add Service Information Note to the Required Actions
JAL requested that the FAA add a note referenced in GE CF34-8E
Service Bulletin (SB) 75-0021 R00 to the Required Actions, which
states, ``For all OBVs, if the OBV was upgraded per S/B 75-0018 or the
OBV cap was replaced per GEK 117619, CF34-8E Component Maintenance
Manual (CMM), 80-12-41, Revision 03 or higher, the flight hours since
upgrade or flight hours since the cap was replaced, as applicable, can
be used instead of flight hours since new.''
In response to JAL's request, the FAA added paragraph (g)(7) to
this AD.
Comments on the Costs of Compliance
SkyWest commented that they have found the costs to convert part
number (P/N) 4123T71P02 or P/N 4123T71P03 are closer to $25,000 to
$30,000 than the estimated $17,000 stated in the NPRM. SkyWest also
commented that replacing the OBV on CF34-8E engines would take more
than the 2 hours estimated in the NPRM. SkyWest reasoned that in their
experience, it could take 8 hours to replace the OBV on CF34-8E
engines.
In response to SkyWest's comment regarding the estimated costs to
replace the OBV, the FAA updated the estimated parts costs from $17,230
to $20,330 in the Costs of Compliance section of this AD. The FAA
disagrees with revising the estimated labor cost to replace the OBV.
The cost analysis in AD rulemaking actions typically includes only the
costs associated with complying with the AD and does not include
secondary costs. The FAA's cost estimate includes the estimated work
hours and parts costs to perform the required actions.
Comments on Part Supply Shortages
SkyWest noted concerns with OBVs modified to P/N 4123T71P06 since
only the original equipment manufacturer (OEM) could modify the OBVs.
SkyWest also commented that the OEM is currently having parts supply
shortages that could jeopardize modifying the OBVs in the required
timeline as proposed in paragraphs (g)(3) and (4) of the NPRM.
In response to SkyWest's comments, GE has communicated with the
supplier and confirmed there is sufficient capacity and margin to meet
the compliance times required by this AD. GE has also requested that
the supplier plan improvements for engagement and logistics with the
operators.
Support for the AD
ALPA expressed support for the AD as written.
Conclusion
The FAA reviewed the relevant data, considered any comments
received, and determined that air safety requires adopting the AD as
proposed. Accordingly, the FAA is issuing this AD to address the unsafe
condition on these products. Except for minor editorial changes, and
any other changes described previously, this AD is adopted as proposed
in the NPRM. None of the changes will increase the economic burden on
any operator.

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
The FAA has determined that 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.
