Self-Regulatory Organizations; NASDAQ OMX BX, Inc.; Notice of
Filing and Immediate Effectiveness of Proposed Rule Change To Change
the Name of the BX Ouch BBO Feed to the BX MatchView Feed and To Modify
Its Contents

August 30, 2011.
    Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934
(``Act'') \1\, and Rule 19b-4 \2\ thereunder, notice is hereby given
that on August 25, 2011, NASDAQ OMX BX, Inc. (``BX'' or ``Exchange'')
filed with the Securities and Exchange Commission (``SEC'' or
``Commission'') the proposed rule change as described in Items I and
II, below, which Items have been prepared by the Exchange. The
Commission is publishing this notice to solicit comments on the
proposed rule change from interested persons.

I. Self-Regulatory Organization's Statement of the Terms of Substance
of the Proposed Rule Change

    The Exchange, pursuant to Section 19(b)(1) of the Act \3\ and Rule
19b-4 thereunder,\4\ proposes to change the name of the BX Ouch BBO
Feed to the BX MatchView Feed (the ``Feed'') and to modify the contents
of the Feed in two ways. The Feed provides a view of how the Exchange
views the Best Bid and Offer (``BBO'') available from all market
centers for each individual security the Exchange trades.

    The text of the proposed rule change is available from BX's Web
site at http://nasdaqomxbx.cchwallstreet.com/NASDAQOMXBX/Filings/, at
BX's principal office, and at the Commission's Public Reference Room.

II. Self-Regulatory Organization's Statement of the Purpose of, and
Statutory Basis for, the Proposed Rule Change

    In its filing with the Commission, the Exchange included statements
concerning the purpose of and basis for the proposed rule change and
discussed any comments it received on the proposed rule change. The
Exchange has prepared summaries, set forth in sections A, B, and C
below, of the most significant aspects of such statements.

A. Self-Regulatory Organization's Statement of the Purpose of, and
Statutory Basis for, the Proposed Rule Change

1. Purpose
    This proposal regards the BX MatchView Feed (formerly known as the
BX Ouch BBO Feed), a data feed that represents the Exchange's view of
best bid and offer data received from all market centers. The Feed is
available to all Exchange members and market participants equally at no
charge, offering all participants transparent, real-time data
concerning the Exchange's view of the BBO data. The Exchange makes the
Feed available on a subscription basis to market participants that are
connected to the Exchange whether through extranets, direct connection,
or Internet-based virtual private networks.
    Currently, the Feed reflects the Exchange's view of the BBO data,
at any given time, based on orders executed on the Exchange and updated
quote information from the network processors.\7\ The Feed contains the
following data elements: symbol, bid price, and ask price.\8\ Unlike
the BX TotalView feed, the MatchView feed does not contain information
about individual orders, either those residing within the Exchange
system or those executed or routed by the Exchange. Unlike the network
processor feeds containing the National Best Bid and Offer (``NBBO''),
the MatchView Feed does not identify either the market center quoting
the BBO or the size of the BBO quotes. It merely contains the symbol
and bid and offer prices.
---------------------------------------------------------------------------

    \7\ The Feed will not reflect all information available to the
Exchange. Specifically, the Feed will exclude information about the
routing of orders to away exchanges. Thus, although the Exchange
execution system and routing engine will know when a bid or offer
from an away market is no longer available because the Exchange has
routed an order to the bid or offer, the Feed will not reflect such
routing activity.
    \8\ The Feed also contains a time stamp and message type field
for reference.
---------------------------------------------------------------------------

    The Exchange is modifying the inputs used for calculating the
prices reflected on the Feed. Currently, the Feed reflects bids and
offers contained on data feeds from the network processors, as well as
certain BX orders referenced below. In the future, the Feed will
continue to reflect these orders entered on the Exchange but rather
than reflect only individual exchange bids and offers received from the
network processors, the Feed will reflect individual exchange bids and
offers received either from the network processor or directly from an
exchange that disseminates bids and offers to vendors via a proprietary
data feed. The Exchange will reflect bids and offers from another
exchange's proprietary data feed only when the Exchange deems the
proprietary data feed to be sufficiently reliable and also faster than
the network processor.\9\
---------------------------------------------------------------------------

    \9\ The Exchange is also changing its policies and procedures
under Regulation NMS governing the data feeds used by its execution
system and routing engine. Current policies state that those systems
use data provided by the network processors. In the future, those
systems will use data provided either by the network processors or
by proprietary feeds offered by certain exchanges directly to
vendors. The determination of which data feed to utilize will be the
same as the determination made with respect to the Feed. In other
words, the Exchange execution system, routing engine and Feed will
each utilize the same data for a given exchange although, as set
forth in footnote 5, the Feed does not contain all information
available to the execution system and routing engine.
---------------------------------------------------------------------------

    This determination--whether to utilize bids and offers from the
network processor feed or from a direct proprietary data feed--will be
made by the Exchange on a market-by-market basis based upon objective
criteria about reliability and speed. The determination, once made,
will apply to all bids and offers from an exchange; it will not be made
on a stock-by-stock basis. Additionally, the determination,

once made, will be valid until such time as the away exchange stops
disseminating the proprietary data feed in a manner that meets BX's
objective criteria (for example, when that exchange experiences
operational difficulties that reduce the reliability and speed of its
proprietary data feed). For exchanges that do not disseminate
proprietary data feeds or whose proprietary data feeds lack sufficient
reliability and speed, the Feed will continue to reflect bids and
offers disseminated via the network processor feeds.
    Additionally, in a previous filing, the Exchange noted that the
Feed depicts the Exchange's view of the BBO for all markets other than
the Exchange.\10\ In one narrow set of circumstances, the Feed will
show the BBO for all markets including the Exchange. Specifically, an
order received by the Exchange that improves the BBO will be reflected
in the Feed when three circumstances are met: (1) The Exchange receives
an order marked by the entering member as any visible bookable order
that is not an IOC and is an ``Inter-market Sweep'' (an order known as
a ``Day ISO''); (2) the Day ISO order is priced higher than the current
Best Bid or lower than the current Best Offer disseminated by the
network processor or applicable exchange proprietary data feed; and (3)
the Day ISO represents the new best bid or offer on the Exchange. In
those circumstances, the new best bid or offer on the Exchange will be
transmitted to the network processor and then reflected on the Feed
(and the Exchange's other proprietary data feeds, such as BX
TotalView). As stated above, the Feed does not show the market center
responsible (whether the Exchange or an away market) for either the
Best Bid or Best Offer reflected on the Feed.
---------------------------------------------------------------------------

    \10\ See Securities Exchange Act Release No. 61452 (Feb. 1,
2010), 75 F.R. (sic) 6232 (Feb. 8, 2010) (filing SR-BX-2010-010).
---------------------------------------------------------------------------

    These modifications to the Feed will enhance market transparency
and foster competition among orders and markets. Member firms may use
the Feed to more accurately price their orders based on the Exchange's
view of what the BBO is at any point in time, including bids and offers
received via proprietary data feeds which may not be reflected in the
official NBBO due to latencies inherent in the NBBO's dissemination. As
a consequence, member firms may more accurately price their orders on
the Exchange, thereby avoiding price adjustments by the Exchange based
on a quote that is no longer available. Additionally, members can use
the Feed to price orders more aggressively to narrow the NBBO and
provide better reference prices for investors.
2. Statutory Basis
    The Exchange believes that the proposed rule change is consistent
with the provisions of Section 6 of the Act,\11\ in general and with
Sections 6(b)(5) of the Act,\12\ in particular in that it is designed
to prevent fraudulent and manipulative acts and practices, to promote
just and equitable principles of trade, to foster cooperation and
coordination with persons engaged in regulating, clearing, settling,
processing information with respect to, and facilitating transactions
in securities, to remove impediments to and perfect the mechanism of a
free and open market and a national market system, and, in general, to
protect investors and the public interest. The Exchange believes that
this proposal is in keeping with those principles by enhancing
transparency through the dissemination of the most accurate quotations
data and by clarifying its contents.

    \11\ 15 U.S.C. 78f.
    \12\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------

B. Self-Regulatory Organization's Statement on Burden on Competition

    The Exchange does not believe that the proposed rule change will
result in any burden on competition that is not necessary or
appropriate in furtherance of the purposes of the Act, as amended.

C. Self-Regulatory Organization's Statement on Comments on the Proposed
Rule Change Received from Members, Participants, or Others

    No written comments were either solicited or received.

III. Date of Effectiveness of the Proposed Rule Change and Timing for
Commission Action

    Because the foregoing proposed rule change does not: (i)
Significantly affect the protection of investors or the public
interest; (ii) impose any significant burden on competition; and (iii)
become operative for 30 days from the date on which it was filed, or
such shorter time as the Commission may designate, it has become
effective pursuant to Section 19(b)(3)(A) of the Act \13\ and Rule 19b-
4(f)(6) thereunder.\14\
---------------------------------------------------------------------------

    \13\ 15 U.S.C. 78s(b)(3)(A).
    \14\ 17 CFR 240.19b-4(f)(6). In addition, Rule 19b-4(f)(6)
requires a self-regulatory organization to give the Commission
written notice of its intent to file the proposed rule change at
least five business days prior to the date of filing of the proposed
rule change, or such shorter time as designated by the Commission.
The Exchange has satisfied this requirement.
---------------------------------------------------------------------------

    A proposed rule change filed pursuant to Rule 19b-4(f)(6) under the
Act \15\ normally does not become operative for 30 days after the date
of its filing. However, Rule 19b-4(f)(6) \16\ permits the Commission to
designate a shorter time if such action is consistent with the
protection of investors and the public interest. The Exchange requests
that the Commission waive the 30-day operative delay because it would
permit the Exchange to immediately provide the new content of the BX
MatchView Feed to market participants. The Commission believes that
waiving the 30-day operative delay \17\ is consistent with the
protection of investors and the public interest and designates the
proposal operative upon filing.
---------------------------------------------------------------------------

    \15\ 17 CFR 240.19b-4(f)(6).
    \16\ 17 CFR 240.19b-4(f)(6).
    \17\ For purposes only of waiving the 30-day operative delay,
the Commission has considered the proposed rule's impact on
efficiency, competition, and capital formation. See 15 U.S.C.
78c(f).
---------------------------------------------------------------------------

    At any time within 60 days of the filing of the proposed rule
change, the Commission summarily may temporarily suspend such rule
change if it appears to the Commission that such action is necessary or
appropriate in the public interest, for the protection of investors, or
otherwise in furtherance of the purposes of the Act. If the Commission
takes such action, the Commission shall institute proceedings to
determine whether the proposed rule change should be approved or
disapproved.

arguments concerning the foregoing, including whether the proposed rule
change is consistent with the Act. Comments may be submitted by any of

39-19699; AD 2019-15-06]
RIN 2120-AA64

Airworthiness Directives; Engine Alliance Turbofan Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2018-22-07
for all Engine Alliance (EA) GP7270, GP7272, and GP7277 model turbofan
engines. AD 2018-22-07 required inspection of the stage 6 seal ring for
correct installation and inspection of the high-pressure compressor
(HPC) stages 2-5 spool for cracks and, depending on the results of the
inspections, replacement of the HPC stages 2-5 spool with a part
eligible for installation. This AD requires the same inspections but
reduces the inspection interval and adds a repetitive inspection and a
mandatory terminating action. This AD was prompted by a shop finding of
axial cracks in the interstage 5-6 seal teeth of the HPC stages 2-5
spool spacer arm due to an incorrectly installed stage 6 seal ring. The
FAA is issuing this AD to address the unsafe condition on these
products.

DATES: This AD is effective August 30, 2019.
    The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of August 30,
2019.
    The FAA must receive any comments on this AD by September 30, 2019.

SUPPLEMENTARY INFORMATION:

Discussion

    The FAA issued AD 2018-22-07, Amendment 39-19480 (83 FR 66609,
December 27, 2018), (``AD 2018-22-07'') for all EA GP7270, GP7272, and
GP7277 model turbofan engines. AD 2018-22-07 required inspection of the
stage 6 seal ring for correct installation and inspection of the HPC
stages 2-5 spool for cracks and, depending on the results of the
inspections, replacement of the HPC stages 2-5 spool with a part
eligible for installation. AD 2018-22-07 resulted from a shop finding
of axial cracks in the HPC interstage 5-6 seal teeth of the HPC stages
2-5 spool spacer arm due to an incorrectly installed stage 6 seal ring.
The FAA issued AD 2018-22-07 to prevent failure of the HPC interstage
5-6 seal teeth and uncontained release of the HPC stages 2-5 spool.

Actions Since AD 2018-22-07 Was Issued

    Since the FAA issued AD 2018-22-07, EA identified additional cracks
as a result of inspections required by AD 2018-22-07. After further
analysis, EA identified a subpopulation of parts that had the HPC rotor
assembly disassembled and reassembled, which require additional
inspections. EA subsequently completed a new safety risk assessment
and, based on the findings, decided to retain the previous inspections
but also add repetitive inspections and an additional in-shop
inspection as a terminating action. The in-shop inspections are a
terminating action for the engines with HPC stages 2-5 spools
identified in paragraph (g)(2) of this AD. The FAA is issuing this AD
to address the unsafe condition on these products.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed EA Alert Service Bulletin (ASB) EAGP7-A72-395,
Revision No. 3, dated June 3, 2019; EA Service Bulletin (SB) EAGP7-72-
413, dated February 4, 2019; and EA SB EAGP7-72-398, dated February 4,
2019. EA ASB EAGP7-A72-395 describes procedures for performing a
borescope inspection (BSI) of the HPC stages 2-5 spool for cracks,
visual inspection of the stage 6 seal ring for correct installation,
visual inspection of the HPC interstage 5-6 seal teeth for damage, and
removal and replacement of parts if damage is found outside serviceable
limits. EA SB EAGP7-72-413 describes procedures for performing a
repetitive BSI of the aft and forward HPC interstage 5-6 seal teeth for
cracks or missing coating. EA SB EAGP7-72-398 describes procedures for
performing an ECI and dimensional inspection of the HPC stages 2-5
spool interstage 5-6 seal teeth for cracks. 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

    The FAA is issuing this AD because it evaluated all the relevant
information and determined the unsafe condition described previously is
likely to exist or develop in other products of the same type design.

AD Requirements

    This AD requires an initial inspection of the HPC stage 6 seal ring
for correct installation and inspection of the HPC stages 2-5 spool for
cracks or missing coating. This AD also requires repetitive on-wing
inspections for a sub-population of HPT stages 2-5 spools. This AD
requires removal and replacement of the HPC stages 2-5 spool if, as the
result of any inspection required by this AD, the stage 6 seal ring is
found installed incorrectly or the HPC

interstage 5-6 seal teeth are found cracked or are missing coating. As
terminating action to the repetitive on-wing inspections, this AD
requires additional in-shop inspections and replacement of the HPC
stages 2-5 spool based on the results of those inspections.

FAA's Justification and Determination of the Effective Date

    No domestic operators use this product. Therefore, the FAA finds
good cause that notice and opportunity for prior public comment are
unnecessary. In addition, for the reason stated above, the FAA finds
that good cause exists for making this amendment effective in less than
30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight
safety, and the FAA did not provide you with notice and an opportunity
to provide your comments before it becomes effective. However, the FAA
invites you to send any written data, views, or arguments about this
final rule. Send your comments to an address listed under the ADDRESSES
section. Include the docket number FAA-2019-0459 and product identifier
2018-NE-36-AD at the beginning of your comments. The FAA specifically
invites comments on the overall regulatory, economic, environmental,
and energy aspects of this final rule. The FAA will consider all
comments received by the closing date and may amend this final rule
because of those comments.
    The FAA will post all comments received, without change, to http://www.regulations.gov, including any personal information you provide.
The FAA will also post a report summarizing each substantive verbal
contact received about this final rule.

Regulatory Flexibility Act

    The requirements of the Regulatory Flexibility Act (RFA) do not
apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt
a rule without prior notice and comment. Because the FAA has determined
that it has good cause to adopt this rule without notice and comment,
RFA analysis is not required.

Costs of Compliance

    The FAA estimates that this AD affects zero engines installed on
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 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

    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, and
    (2) Will not affect intrastate aviation in Alaska.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the
Administrator, the FAA amends part 39 of the Federal Aviation
Regulations (14 CFR part 39) as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.

Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by removing Airworthiness Directive (AD)
2018-22-07, Amendment 39-19480 (83 FR 66609, December 27, 2018) and
adding the following new AD:

2019-15-06 Engine Alliance: Amendment 39-19699; Docket No. FAA-2019-
0459; Product Identifier 2018-NE-36-AD.

(a) Effective Date

    This AD is effective August 30, 2019.

(b) Affected ADs

    This AD replaces AD 2018-22-07, Amendment 39-19480 (83 FR 66609,
December 27, 2018).

(c) Applicability

    This AD applies to all Engine Alliance (EA) GP7270, GP7272, and
GP7277 model turbofan engines.

(d) Subject

    Joint Aircraft System Component (JASC) Code 7230, Turbine Engine
Compressor Section.

(e) Unsafe Condition

    This AD was prompted by a shop finding of axial cracks in the
interstage 5-6 seal teeth of the high-pressure compressor (HPC)
stages 2-5 spool spacer arm due to an incorrectly installed stage 6
seal ring. The FAA is issuing this AD to prevent failure of the HPC
interstage 5-6 seal teeth and uncontained HPC stages 2-5 spool
release. The unsafe condition, if not addressed, could result in an
uncontained release of the HPC stages 2-5 spool, damage to the
engine, and damage to the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified,
unless already done.

(g) Required Actions

    (1) For all HPC stages 2-5 spools, perform an initial borescope
inspection (BSI) of the HPC stage 6 seal ring position:
    (i) Borescope inspect the HPC stage 6 seal ring location in
accordance with the Accomplishment Instructions, paragraph 1.F, of
EA Alert Service Bulletin (ASB) EAGP7-A72-395, Revision No. 3, dated
June 3, 2019, and within the compliance times specified in Table 1
to paragraph (g)(1) of this AD or within 230 engine cycles after the
effective date of this AD, whichever occurs first. If the HPC stage
6 seal ring is installed incorrectly, remove the HPC stages 2-5
spool from service within 50 engine cycles and replace with a part
eligible for installation, and correct the location of the stage 6
seal ring.
    (ii) Borescope inspect the HPC interstage 5-6 seal tooth forward
and aft face for cracks and missing coating in accordance with the
Accomplishment Instructions, paragraphs 2.C and 2.E, of EA ASB
