Discussion
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Community, has issued EASA AD 2017–
0151, dated August 18, 2017 (referred to
hereinafter as ‘‘the MCAI’’), to correct an
unsafe condition for the specified
products. The MCAI states:
A recent design review identified the
possibility of failure of the power turbine
(PT) or quill shaft splines.
This condition, if not corrected, could lead
to a PT rotor overspeed, with consequent
release of PT blade(s), possibly resulting in
high energy debris and damage to, and/or
reduced control of, the aeroplane.

This AD is issued in accordance with
authority delegated by the Executive
Director, Aircraft Certification Service,
as authorized by FAA Order 8000.51C.
In accordance with that order, issuance
of ADs is normally a function of the
Compliance and Airworthiness
Division, but during this transition
period, the Executive Director has
delegated the authority to issue ADs
applicable to engines, propellers, and
associated appliances to the Manager,

FAA’s Determination and Requirements
of This Proposed AD
This product has been approved by
the aviation authority of the Czech
Republic and is approved for operation
in the United States. Pursuant to our
bilateral agreement with the European
Community, EASA has notified us of
the unsafe condition described in the
MCAI and service information
referenced above. We are proposing this
AD because we evaluated all
information provided by EASA and
determined the unsafe condition exists
and is likely to exist or develop on other
products of the same type design. This
proposed AD would require installing a
modified engine outlet system.
Costs of Compliance
We estimate that this proposed AD
affects 167 engines installed on
airplanes of U.S. registry.
We estimate the following costs to
comply with this proposed AD:
Engine and Propeller Standards Branch,
Policy and Innovation Division.
Regulatory Findings
We determined that this proposed AD
would not have federalism implications
under Executive Order 13132. This
proposed AD would 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 this proposed regulation:
(1) Is not a ‘‘significant regulatory
action’’ under Executive Order 12866,

1979),
(3) Will not affect intrastate aviation
in Alaska, and
(4) Will not have a significant
economic impact, positive or negative,
on a substantial number of small entities
under the criteria of the Regulatory

Background
The regulations at 50 CFR 660.50(d)
outline the procedures for implementing
the treaty rights that Pacific Coast treaty
Indian tribes have to harvest groundfish
in their usual and accustomed fishing
areas in U.S. waters. Section 660.50(d)
establishes the process by which the
tribes with treaty fishing rights in the
area covered by the FMP request
allocations, set-asides, or regulations
specific to the tribes, in writing, during
the biennial harvest specifications and
management measures process. The
regulations state that the Secretary will
develop tribal allocations and
regulations in consultation with the
affected tribe(s) and, insofar as possible,
with tribal consensus. The procedures
NMFS employs in implementing tribal
treaty rights under the FMP were
designed to provide a framework
process by which NMFS can
accommodate tribal treaty rights by
setting aside appropriate amounts of
fish in conjunction with the Pacific
Fishery Management Council process
for determining harvest specifications
and management measures.
Since the FMP has been in place,
NMFS has been allocating a portion of
the U.S. TAC (called Optimum Yield
(OY) or Annual Catch Limit (ACL) prior
to 2012) of Pacific whiting to the tribal
fishery, following the process
established in 50 CFR 660.50(d). The
tribal allocation is subtracted from the
U.S. Pacific whiting TAC before
allocation to the non-tribal sectors.
There are four tribes that can
participate in the tribal Pacific whiting
fishery: The Hoh Tribe, the Makah
Tribe, the Quileute Tribe and the
Quinault Indian Nation (collectively,
the ‘‘Treaty Tribes’’). The Hoh Tribe has
not expressed an interest in
participating to date. The Quileute Tribe
and Quinault Indian Nation have
expressed interest in commencing
participation in the Pacific whiting
fishery. However, to date, only the
Makah Tribe has prosecuted a tribal
fishery for Pacific whiting. They have
harvested Pacific whiting since 1996
using midwater trawl gear. Tribal
allocations have been based on
discussions with the Tribes regarding
their intent for those fishing years. Table
1 below provides a history of U.S. TACs
and annual tribal allocation in metric
tons (mt).

Discussion
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued EASA
AD 2017-0151, dated August 18, 2017 (referred to hereinafter as ``the
MCAI''), to correct an unsafe condition for the specified products. The
MCAI states:
A recent design review identified the possibility of failure of
the power turbine (PT) or quill shaft splines.
This condition, if not corrected, could lead to a PT rotor
overspeed, with consequent release of PT blade(s), possibly
resulting in high energy debris and damage to, and/or reduced
control of, the aeroplane.
To address this potential unsafe condition, GE Aviation Czech
(GEAC) designed a modification (mod) of the engine outlet system and
issued Alert Service Bulletins (ASB) ASB-M601E-72-00-00-0070, ASB-
M601D-72-00-00-0053, ASB-M601F-72-00-00-0036, ASB-M601T-72-00-00-
0029, ASB-M601Z-72-00-00-0039, ASB-H75-72-00-00-0011, ASB-H80-72-00-
00-0025 and ASB-H85-72-00-00-0007 (single document, hereafter
referred to as ``the ASB'' in this AD), providing instructions for
modification of engines in service.
For the reason described above, this AD requires modification of
the affected engines, and prohibits installation of pre-mod parts.
You may obtain further information by examining the MCAI in the AD
docket on the internet at https://www.regulations.gov by searching for
and locating Docket No. FAA-2017-0967.
Related Service Information Under 1 CFR Part 51
We reviewed GE Aviation Czech Alert Service Bulletin (ASB) ASB-
M601E-72-00-00-0070 [02], ASB-M601D-72-00-00-0053 [02], ASB-M601F-72-
00-00-0036 [02], ASB-M601T-72-00-00-0029 [02], ASB-M601Z-72-00-00-0039
[02], ASB-H75-72-00-00-0011 [02], ASB-H80-72-00-00-0025 [02], and ASB-
H85-72-00-00-0007 [02] (single document), dated June 12, 2017. The ASB
describes procedures for removal and replacement of the engine outlet
system hardware. 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 the ADDRESSES section.
FAA's Determination and Requirements of This Proposed AD
This product has been approved by the aviation authority of the
Czech Republic and is approved for operation in the United States.
Pursuant to our bilateral agreement with the European Community, EASA
has notified us of the unsafe condition described in the MCAI and
service information referenced above. We are proposing this AD because
we evaluated all information provided by EASA and determined the unsafe
condition exists and is likely to exist or develop on other products of
the same type design. This proposed AD would require installing a
modified engine outlet system.
Costs of Compliance
We estimate that this proposed AD affects 167 engines installed on
airplanes of U.S. registry.
We estimate the following costs to comply with this proposed 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.
We are 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.
This AD is issued in accordance with authority delegated by the
Executive Director, Aircraft Certification Service, as authorized by
FAA Order 8000.51C. In accordance with that order, issuance of ADs is
normally a function of the Compliance and Airworthiness Division, but
during this transition period, the Executive Director has delegated the
authority to issue ADs applicable to engines, propellers, and
associated appliances to the Manager, Engine and Propeller Standards
Branch, Policy and Innovation Division.
Regulatory Findings
We determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 this proposed
regulation:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
[[Page 3289]]
(2) Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979),
(3) Will not affect intrastate aviation in Alaska, and
(4) 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.
