Airworthiness Directives; The Boeing Company Model 727, 727C,
727-100, 727-100C, 727-200, and 727-200F Series Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for the
products listed above. This AD requires replacing the existing
unshielded fuel quantity indication system (FQIS) wire bundles with
double shielded FQIS wire bundles, installing a new wire feed-through
fitting, and grounding the wire shields, as applicable; and doing
repetitive low frequency eddy current (LFEC) inspections for cracking
of the fuselage skin, and corrective actions if necessary. This AD also
requires revising the maintenance program to incorporate certain
airworthiness limitations. This AD was prompted by fuel system reviews
conducted by the manufacturer. We are issuing this AD to increase the
level of protection from lightning strikes and prevent the potential of
ignition sources inside fuel tanks, which, in combination with
flammable fuel vapors, could result in fuel tank explosions and
consequent loss of the airplane.

DATES: This AD is effective July 15, 2011.
    The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of July 15, 2011.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an airworthiness directive (AD) that would apply to
the specified products. That NPRM published in the Federal Register on
January 3, 2011 (76 FR 31). That NPRM proposed to require replacing the
existing unshielded fuel quantity indication system (FQIS) wire bundles
with double shielded FQIS wire bundles, installing a new wire feed-
through fitting, and grounding the wire shields, as applicable; and
doing repetitive low frequency eddy current (LFEC) inspections for
cracking of the fuselage skin, and corrective actions if necessary.
That NPRM also proposed to require revising the maintenance program to
incorporate certain airworthiness limitations.

Comments

    We gave the public the opportunity to participate in developing
this AD. The following presents the comment received on the proposal
and the FAA's response to the comment.

Request for Explanation of Alternative Method of Compliance (AMOC)
Authority for Structures Portions of the NPRM

    Boeing requested that we explain that some designees with AMOC
authority may be necessary for the structural portions of the AD.
Boeing stated that repairs to airplane structure, if needed, would also
be an AMOC to the AD and would need to be noted as such and approved by
the FAA or a Boeing Authorized Representative designated with AMOC
authority for the structural aspects of this installation. Boeing added
that any repair would need to address damage tolerance issues
associated with 14 CFR 25.571 and 14 CFR part 26, subpart E. of the
Federal Aviation Regulations. Boeing stated that these requirements are
the basis for the inspections provided in Boeing Service Bulletin 727-
28-0131, dated August 18, 2010, and changes to the installation with
repairs may revise the inspection requirements.
    We agree with the request to add explanatory information to
paragraph (i) of this AD. Any structural repairs that cannot be done in
accordance with the accomplishment instructions of Boeing Service
Bulletin 727-28-0131, dated August 18, 2010, will require a request for
an AMOC. The requested AMOC, if it provides an acceptable level of
safety, may be approved by the Boeing Commercial Airplanes Organization
Designation Authorization (ODA) that has been authorized by the
Manager, Seattle ACO to make those findings. Paragraph (i) of this AD
has been changed to explain that some designees with AMOC authority for
the structures portions of the AD might be necessary.

Conclusion

    We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
the AD with the change described previously and minor editorial
changes. We have determined that these minor changes:
     [Agr]re consistent with the intent that was proposed in
the NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was
already proposed in the NPRM.
    We also determined that these changes will not increase the
economic burden on any operator or increase the scope of the AD.

Costs of Compliance

    We estimate that this AD affects 566 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

    We have received no definitive data that would enable us to provide
a cost estimate for the on-condition action specified in 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.
    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.

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) Is not a ``significant rule'' under 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.

    Note 1:  This AD requires revisions to certain operator
maintenance documents to include new inspections. Compliance with
these inspections is required by 14 CFR 91.403(c). For airplanes
that have been previously modified, altered, or repaired in the
areas addressed by these inspections, the operator may not be able
to accomplish the inspections described in the revisions. In this
situation, to comply with 14 CFR 91.403(c), the operator must
request approval for an alternative method of compliance according
to paragraph (l) of this AD. The request should include a
description of changes to the required inspections that will ensure
the continued operational safety of the airplane.

Subject

    (d) Joint Aircraft System Component (JASC)/Air Transport
Association (ATA) of America Code 28, Fuel.

Unsafe Condition

    (e) This AD was prompted by fuel system reviews conducted by the
manufacturer. We are issuing this AD to increase the level of
protection from lightning strikes and prevent the potential of
ignition sources inside fuel tanks, which, in combination with
flammable fuel vapors, could result in fuel tank explosions and
consequent loss of the airplane.

Compliance

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

Installation

    (g) Within 60 months after the effective date of this AD,
install double shielded fuel quantity indicating system (FQIS) wire
bundles, install a new wire feed-through fitting, and ground the
wire shields, as applicable, in accordance with Part 1 of the
Accomplishment Instructions of Boeing Service Bulletin 727-28-0131,

occurs later. Repeat the inspections thereafter at intervals not to
exceed 8,000 flight cycles.
    (2) For Model 727-200 and 727-200F series airplanes: Before the
accumulation of 45,000 total flight cycles, or within 16,000 flight
cycles after the effective date of this AD, whichever occurs later.
Repeat the inspections thereafter at intervals not to exceed 16,000
flight cycles.
    (i) If any cracking is found during any inspection required by
paragraph (h) of this AD: Before further flight, repair the crack in
accordance with a method approved by the Manager, Seattle ACO, FAA.
For a repair method to be approved, the repair must meet

the certification basis of the airplane, and the approval must
specifically refer to this AD. An alternative method of compliance
that provides an acceptable level of safety may be used for any
repair required by this AD if it is approved by the Boeing
Commercial Airplanes Organization Designation Authorization (ODA)
that has been authorized by the Manager, Seattle ACO, to make those
findings.

SECURITIES AND EXCHANGE COMMISSION

[Release No. 34-85636; File No. SR-CboeBZX-2019-021]

Self-Regulatory Organizations; Cboe BZX Exchange, Inc.; Notice of
Filing and Immediate Effectiveness of a Proposed Rule Change Relating
To Amend the Fee Schedule Applicable to Members and Non-Members of the
Exchange Pursuant to BZX Rules 15.1(a) and (c)

April 12, 2019.
    Pursuant to Section 19(b)(1) \1\ of the Securities Exchange Act of
1934 (the ``Act'') \2\ and Rule 19b-4 thereunder,\3\ notice is hereby
given that, on March 29, 2019, Cboe BZX Exchange, Inc. (the
``Exchange'' or ``BZX'') filed with the Securities and Exchange
Commission (the ``Commission'') the proposed rule change as described
in Items I and II, below, which Items have been prepared by the self-
regulatory organization. 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

    BZX Exchange, Inc. (the ``Exchange'' or ``BZX'') is filing with the
Securities and Exchange Commission (``Commission'') a proposed rule
change to amend the fee schedule applicable to Members and non-Members
\4\ of the Exchange pursuant to BZX Rules 15.1(a) and (c). The text of
the proposed rule change is attached as Exhibit 5 [sic].
---------------------------------------------------------------------------

    \4\ A Member is defined as ``any registered broker or dealer
that has been admitted to membership in the Exchange.'' See Exchange
Rule 1.5(n).
---------------------------------------------------------------------------

    The text of the proposed rule change is also available on the
Exchange's website (http://markets.cboe.com/us/equities/regulation/rule_filings/bzx/), at the Exchange's Office of the Secretary, 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 self-regulatory organization
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 text of those statements may be examined at
the places specified in Item IV below. The Exchange has prepared
summaries, set forth in sections A, B, and C below, of the most
significant parts of such statements.

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

1. Purpose
    The Exchange proposes to amend its fee schedule applicable to its
equities trading platform (``BZX Equities'') to add a Non-Displayed Add
Volume Tier, effective April 1, 2019.
    The Exchange currently offers three Non-Displayed Add Volume Tiers
under footnote 1, which provide an enhanced rebate between $0.0018 to
$0.0025 per share for qualifying Tape A, B, and C non-displayed orders
that add liquidity (i.e., yield fee codes HV, HB, and HY,
respectively). The Exchange now proposes to add a fourth Non-Displayed
Add Volume Tier. Under the proposed Non-Displayed Add Volume Tier 4, a
Member may receive an enhanced rebate of $0.0029 per share where they
add an ADV \5\ greater than or equal to 0.38% of the TCV \6\ as Non-
Displayed orders that yield fee codes HB, HI,\7\ HV or HY. The Exchange
believes the proposed new tier will encourage Members to increase their
liquidity on the exchange.
---------------------------------------------------------------------------

    \5\ ``ADV'' means average daily volume calculated as the number
of shares added or removed, combined, per day. ADAV and ADV are
calculated on a monthly basis. See Exchange Fee Schedule.
    \6\ ``TCV'' means total consolidated volume calculated as the
volume reported by all exchanges and trade reporting facilities to a
consolidated transaction reporting plan for the month for which the
fees apply. Id.
    \7\ Fee code HI is appended to non-displayed orders that receive
price improvement and add liquidity. Id.
---------------------------------------------------------------------------

2. Statutory Basis
    The Exchange believes that the proposed rule changes are consistent
with the objectives of Section 6 of the Act,\8\ in general, and
furthers the objectives of Section 6(b)(4),\9\ in particular, as it is
designed to provide for the equitable allocation of reasonable dues,
fees and other charges among its Members and other persons using its
facilities. The Exchange also notes that it operates in a highly-
competitive market in which market participants can readily direct
order flow to competing venues if they deem fee levels at a particular
venue to be excessive or incentives to be insufficient. The proposed
rule changes reflect a competitive pricing structure designed to
incentivize market participants to direct their order flow to the
Exchange.
---------------------------------------------------------------------------

    \8\ 15 U.S.C. 78f.
    \9\ 15 U.S.C. 78f(b)(4).
---------------------------------------------------------------------------

    In particular, the Exchange notes that volume-based rebates such as
that proposed herein have been widely adopted by exchanges, including
the Exchange, and are equitable because they are open to all Members on
an equal basis and provide additional benefits or discounts that are
reasonably related to: (i) The value to an exchange's market quality;
(ii) associated higher levels of market activity, such as higher levels
of liquidity provision and/or growth patterns; and (iii) introduction
of higher volumes of orders into the price and volume discovery
processes. The Exchange believes that the proposed tier is a
reasonable, fair and equitable, and not unfairly discriminatory
allocation of fees and rebates because it will provide Members with an
incentive to reach certain thresholds on the Exchange.
    More specifically, the Exchange believes the proposed Non-Displayed
Add Volume Tier 4 is a reasonable means to encourage Members to
increase their liquidity on the Exchange. The Exchange further believes
that the proposed tier represents an equitable allocation of reasonable
dues, fees, and other charges because the threshold necessary to
achieve the tier encourages Members to add increased liquidity on BZX
each month. The increased liquidity benefits all investors by deepening
the Exchange's liquidity pool, offering additional flexibility for all
investors to enjoy cost savings, supporting the quality of price
discovery, promoting market transparency and improving investor
protection. The Exchange also believes that the proposed rebate is
reasonable based on the difficulty of satisfying the tier's criteria as
compared to the existing Non-Displayed Add Volume tiers, which provide
lower rebates and similar, but less stringent, criteria. Furthermore,
the Exchange believes that the proposed tier is not unfairly
discriminatory as it applies to all members that meet the required
criteria.

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

    The Exchange does not believe that the proposed rule changes will
impose any burden on competition not necessary or appropriate in
furtherance of the purposes of the Act. The Exchange does not believe
the proposed change burdens competition, but rather, enhances
competition as it is intended to increase the competitiveness of BZX by
adopting an additional pricing incentive in order to attract order flow
and incentivize participants to increase their participation on the
Exchange. The Exchange notes that it operates in a highly competitive
market in which market participants can readily direct order flow to
competing venues if they deem fee structures to be unreasonable or
excessive. Accordingly, the Exchange does not believe that the proposed
change will impair the ability of Members or competing venues to
maintain their competitive standing in the financial markets. The
Exchange also notes that the proposed change is intended to enhance the
rebate for liquidity added to the Exchange, which is intended to draw
additional liquidity to the Exchange to the benefit of all market
participants. The Exchange does not believe the proposed amendment
would burden intramarket competition as it would be available to all
Members uniformly.

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

    The Exchange has not solicited, and does not intend to solicit,
comments on this proposed rule change. The Exchange has not received
any unsolicited written comments from Members or other interested
parties.

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

    The foregoing rule change is effective upon filing pursuant to
Section 19(b)(3)(A)(ii) of the Act,\10\ and subparagraph (f)(2) of Rule
19b-4 \11\ thereunder, because it establishes a due, fee, or other
charge imposed by the Exchange.

    \11\ 17 CFR 240.19b-4(f)(2).
---------------------------------------------------------------------------

    At any time within 60 days of the filing of such 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 under Section 19(b)(2)(B) \12\
of the Act to determine whether the proposed rule change should be
approved or disapproved.
