C. How May I Participate in this Meeting?

    You may participate in this meeting by following the instructions
in this unit. To ensure proper receipt by EPA, it is imperative that
you identify docket ID number EPA-HQ-OPP-2008-0836; in the subject line
on the first page of your request.
    1. Written comments. The Agency encourages that written comments be
submitted, using the instructions in ADDRESSES, no later than February
9, 2008, to provide the FIFRA SAP the time necessary to consider and
review the written comments. Written comments are accepted until the
date of the meeting, but anyone submitting written comments after
February 9, 2008 should contact the DFO listed under FOR FURTHER
INFORMATION CONTACT. Anyone submitting written comments at the meeting
should bring 30 copies for distribution to the FIFRA SAP.
    2. Oral comments. The Agency encourages that each individual or
group wishing to make brief oral comments to the FIFRA SAP submit their
request to the DFO listed under FOR FURTHER INFORMATION CONTACT no
later than February 16, 2008, in order to be included on the meeting
agenda. Requests to present oral comments will be accepted until the
date of the meeting and, to the extent that time permits, the Chair of
the FIFRA SAP may permit the presentation of oral comments at the
meeting by interested persons who have not previously requested time.
The request should identify the name of the individual making the
presentation, the organization (if any) the individual will represent,
and any requirements for audiovisual equipment (e.g., overhead
projector, 35 mm projector, chalkboard). Oral comments before the FIFRA
SAP are limited to approximately 5 minutes unless prior arrangements
have been made. In addition, each speaker should bring 30 copies of his
or her comments and presentation slides for distribution to the FIFRA
SAP at the meeting.
    3. Seating at the meeting. Seating at the meeting will be open and
on a first-come basis.
    4. Request for nominations to serve as ad hoc members of the FIFRA
SAP for this meeting. As part of a broader process for developing a
pool of candidates for each meeting, the FIFRA SAP staff routinely
solicits the stakeholder community for nominations of prospective
candidates for service as ad hoc members of the FIFRA SAP. Any
interested person or organization may nominate qualified individuals to
be considered as prospective candidates for a specific meeting.
Individuals nominated for this meeting should have expertise in one or
more of the following areas: Insect population genetics, corn rootworm
biology and population dynamics, simulation modeling for pest
resistance in Bt agricultural systems (preferably maize), and
statistical analysis. Nominees should be scientists who have sufficient
professional qualifications, including training and experience, to be
capable of providing expert comments on the scientific issues for this
meeting. Nominees should be identified by name, occupation, position,
address, and telephone number. Nominations should be provided to the
DFO listed under FOR FURTHER INFORMATION CONTACT on or before December
24, 2008. The Agency will consider all nominations of prospective
candidates for this meeting that are received on or before this date.
However, final selection of ad hoc members for this meeting is a
discretionary function of the Agency.
     The selection of scientists to serve on the FIFRA SAP is based on
the function of the panel and the expertise needed to address the
Agency's charge to the panel. No interested scientists shall be
ineligible to serve by reason of their membership on any other advisory
committee to a Federal department or agency or their employment by a
Federal department or agency except the EPA. Other factors considered
during the selection process include availability of the potential
panel member to fully participate in the panel's reviews, absence of
any conflicts of interest or appearance of lack of impartiality,
independence with respect to the matters under review, and lack of
bias. Although, financial conflicts of interest, the appearance of lack
of impartiality, lack of independence, and bias may result in
disqualification, the absence of such concerns does not assure that a
candidate will be selected to serve on the FIFRA SAP. Numerous
qualified candidates are identified for each panel. Therefore,
selection decisions involve carefully weighing a number of factors
including the candidates' areas of expertise and professional
qualifications and achieving an overall balance of different scientific
perspectives on the panel. In order to have the collective breadth of
experience needed to address the Agency's charge for this meeting, the
Agency anticipates selecting approximately 10 ad hoc scientists.
    FIFRA SAP members are subject to the provisions of 5 CFR part 2634,
Executive Branch Financial Disclosure, as supplemented by the EPA in 5
CFR part 6401. In anticipation of this requirement, prospective
candidates for service on the FIFRA SAP will be asked to submit
confidential financial information which shall fully disclose, among
other financial interests, the candidate's employment, stocks and
bonds, and where applicable, sources of research support. The EPA will
evaluate the candidates financial disclosure form to assess whether
there are financial conflicts of interest, appearance of a lack of
impartiality or any prior involvement with the development of the
documents under consideration (including previous scientific peer
review) before the candidate is considered further for service on the
FIFRA SAP. Those who are selected from the pool of prospective
candidates will be asked to attend the public meetings and to
participate in the discussion of key issues and assumptions at these
meetings. In addition, they will be asked to review and to help
finalize the meeting minutes. The list of FIFRA SAP members
participating at this meeting will be posted on the FIFRA SAP website
at http://epa.gov/scipoly/sap or may be obtained from the OPP
Regulatory Public Docket at http://www.regulations.gov.

 II. Background

 A. Purpose of the FIFRA SAP

    The FIFRA SAP serves as the primary scientific peer review
mechanism of EPA's Office of Prevention, Pesticides and Toxic
Substances (OPPTS) and is structured to provide scientific advice,
information and recommendations to the EPA Administrator on pesticides
and pesticide-related issues as to the impact of regulatory actions on
health and the environment. The FIFRA SAP is a Federal advisory
committee established in 1975 under FIFRA that operates in accordance
with requirements of the Federal Advisory Committee Act. The FIFRA SAP
is composed of a permanent panel consisting of seven members who are
appointed by the EPA Administrator from nominees provided by the
National Institutes of Health and the National Science Foundation.
FIFRA, as amended by FQPA, established a Science Review Board
consisting of at least 60 scientists who are available to the
Scientific Advisory Panel on an ad hoc basis to assist in reviews
conducted by the Scientific Advisory Panel. As a peer review mechanism,
the FIFRA SAP provides comments, evaluations and recommendations to
improve the effectiveness and quality of analyses made by Agency
scientists. Members of the FIFRA SAP are scientists who have sufficient
professional qualifications, including training and experience, to
provide expert advice and recommendation to the Agency.

 B. Public Meeting

    EPA's Office of Pesticide Programs (OPP) has received an
application of registration from Pioneer Hi-Bred International, Inc.
for registration of Optimum[reg] AcreMaxTM 1
Insect Protection, which is a corn seed blend containing seeds that
express the Bt toxins Cry34Ab1, Cry35Ab1, and Cry1F in a stack for corn
rootworm (CRW) and lepidopteran protection mixed with seeds that
express only Cry1F for lepidopteran protection (i.e. ``refuge in the
bag'' for CRW). Pioneer proposes to use a seed blend mixture containing
>= 2% refuge seeds. OPP has reviewed the submitted studies and modeling
chapter and has identified several areas of uncertainties with respect
to CRW biology, population genetics, and modeling. EPA is seeking the
assistance of the FIFRA SAP to address the scientific issues associated
with the seed mix proposal for CRW resistance management and provide
the Agency with guidance as to the implications of the uncertainties.
These areas of uncertainties include:
    1. Mode of action of Cry34/35Ab1 (i.e. toxic or repellent) to
exposed CRW and implications for a seed mix,
    2. Aspects of corn rootworm pest biology including the effects of
delayed emergence and uneven sex ratios on random mating and ultimately
on the rate of resistance evolution in a seed blend environment;
    3. Assumptions about initial resistance gene frequency to Cry34/
35Ab1;
    4. Contributions of tolerance (minor) and resistance (major) genes
and selection consequences in corn rootworm exposed to Cry34/35Ab1 in a
seed blend environment;
    5. Mortality for individuals being heterozygous (XY) and
susceptible (XX) for the tolerance (minor) gene;
    6. The overall simulation model (i.e. is it adequate to evaluate
the proposed seed mix for Cry34/35Ab1); and
    7. The mechanics of mixing refuge seed with Cry34/35Ab1 seed into a
single bag and the potential distribution (i.e. random or non-random)
of refuge plants within planted fields.

C. FIFRA SAP Documents and Meeting Minutes

    EPA's background paper, related supporting materials, charge/
questions to the FIFRA SAP, FIFRA SAP composition i.e., members and ad
hoc members for this meeting, and the meeting agenda will be available
by late January, 2009. In addition, the Agency may provide additional
background documents as the materials become available. You may obtain
electronic copies of these documents, and certain other related
documents that might be available electronically, at http://
www.regulations.gov and the FIFRA SAP homepage at http://www.epa.gov/
scipoly/sap.
    The FIFRA SAP will prepare meeting minutes summarizing its
recommendations to the Agency approximately 90 days after the meeting.

14 CFR Part 39

[Docket No. FAA-2015-3778; Directorate Identifier 2015-NE-27-AD;
Amendment 39-18391; AD 2016-03-04]
RIN 2120-AA64

Airworthiness Directives; Rolls-Royce plc Turbofan Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all
Rolls-Royce plc (RR) RB211-535E4-37, RB211-535E4-B-37, and RB211-535E4-
C-37 turbofan engines. This AD requires recalculating the cyclic life
for certain engine life-limited rotating parts and removing those parts
that have exceeded their cyclic life limit within specified compliance
times. This AD was prompted by a review of operational data that
determined certain RR RB211-535E4-37 engines have been operated to a
more severe flight profile than is consistent with the flight profile
used to establish the cyclic life limits for the rotating parts. We are
issuing this AD to prevent failure of life-limited rotating parts,
uncontained parts release, damage to the engine, and damage to the
airplane.

DATES: This AD becomes effective March 15, 2016.
    The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of March 15,
2016.

ADDRESSES: For service information identified in this AD, contact

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would apply to the specified products. The
NPRM was published in the Federal Register on November 4, 2015 (80 FR
68284). The NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:

    A review of operational flight data has revealed that some
RB211-535 engines may have been operated beyond the flight profile
(FP) assumed by the operator when establishing the operational
limits (life limits) within which the corresponding critical parts
are allowed to remain installed.
    This condition, if not corrected, may lead to critical part
failure, possibly resulting in release of high energy debris, damage
to the aeroplane and/or injury to the occupants.

    To preclude failure of an engine life-limited part, the MCAI
specifies, and this AD would require, recalculating the cyclic life for
certain parts and removing from service those parts that have exceeded
their cyclic life limit within specified compliance times. This AD
would establish a new default Flight Profile G for RR RB211-535E4-37
engine life-limited parts. If, however, operators meet the requirements
of Appendix 6 of RR Alert Non-Modification Service Bulletin (NMSB) No.
RB.211-72-AH972, Revision 3, dated August 28, 2015, they may operate to
Flight Profile A or B. You may obtain further information by examining
the MCAI in the AD docket on the Internet at http://www.regulations.gov
by searching for and locating Docket No. FAA-2015-3778.

Related Service Information Under 1 CFR Part 51

    We reviewed RR Alert NMSB No. RB.211-72-AH972, Revision 3, dated
August 28, 2015. The Alert NMSB describes a new flight profile,
provides procedures for the consumed cyclic life corrections for prior
operation of affected parts, and provides the removal from service
recommendations for parts that have exceeded their cyclic life limit.
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 of this AD.

Comments

    We gave the public the opportunity to participate in developing
this AD. We considered the comments received.

Support for the NPRM (80 FR 68284, November 4, 2015)

    The Boeing Company, FedEx, United Airlines, and American Airlines
expressed support for the NPRM.

Request To Change Actions and Compliance

    United Parcel Service (UPS) requested that the NPRM recognize
digital flight data taken from either the digital flight data recorder
(DFDR) or the digital flight data acquisition unit (DFDAU) as valid
data for RR RB211 flight profile monitoring purposes. The data captured
by the DFDAU is recorded on the DFDR, but DFDAUs are regularly
downloaded for UPS' flight operations quality assurance program. The
DFDAU data is easier to access than pulling a DFDR for data download
purposes.
    We agree. We added a new paragraph to paragraph (e)(1) of this AD
as follows: ``(e)(1)(iv) You may use data from either a digital flight
data acquisition unit or a digital flight data recorder for flight
profile monitoring.''.

Conclusion

    We reviewed the available data, including the comments received,
and determined that air safety and the public interest require adopting
this AD with the changes described previously. We determined that these
changes will not increase the economic burden on any operator or
increase the scope of this AD.

Costs of Compliance

    We estimate that this AD affects 107 engines installed on airplanes
of U.S. registry. Pro-rated cost of the lost cyclic life as a result of
the corrections would be about $25,417,324. We estimate it will take 1
hour to recalculate the consumed cyclic life and revise the engine
records which include 5 minutes (0.083 hours) for record entries. The
average labor rate is $85 per hour. Based on these figures, we estimate
the cost of this AD on U.S. operators to be $25,426,419.

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

    We 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 this AD:
    (1) Is not a ``significant regulatory action'' under Executive
Order 12866,
    (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 to the extent
that it justifies making a regulatory distinction, 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.

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 adding the following new airworthiness
directive (AD):

2016-03-04 Rolls-Royce plc: Amendment 39-18391; Docket No. FAA-2015-
3778; Directorate Identifier 2015-NE-27-AD.

(a) Effective Date

    This AD becomes effective March 15, 2016.

(b) Affected ADs

    None.

(c) Applicability

RB211-535E4-B-37, and RB211-535E4-C-37 turbofan engines.

(d) Reason

    This AD was prompted by a review of operational data that
determined that certain RR RB211-535E4-37 engines have been operated
to a more severe flight profile than is consistent with the flight
profile used to establish the cyclic life limits for the rotating
parts. We are issuing this AD to prevent failure of life-limited
rotating parts, which could result in uncontained parts release,
damage to the engine, and damage to the airplane.

(e) Actions and Compliance

    Comply with this AD within the compliance times specified,
unless already done. Within 21 days after the effective date of this
AD:
    (1) For RR RB211-535E4-37 engines, establish a new flight
profile, Flight Profile G, as the new default profile for flight
operations and new part lives for life-limited parts.
    (i) Use Appendix 6 of RR Alert Non-Modification Service Bulletin
(NMSB) No. RB.211-72-AH972, Revision 3, dated August 28, 2015, to
define Flight Profile G.
    (ii) Use the definition of Flight Profile G in Appendix 6 and
the maximum approved cyclic lives in Appendix 2 of RR Alert NMSB No.
RB.211-72-AH972, Revision 3, dated August 28, 2015, to identify the
new lives for life-limited parts.
    (iii) If operators meet the requirements of Appendix 6 of RR
Alert NMSB No. RB.211-72-AH972, Revision 3, dated August 28, 2015,
they may operate to Flight Profile A or B.
    (iv) You may use data from either a digital flight data
acquisition unit or a digital flight data recorder for flight
profile monitoring.
    (2) For all RR RB211-535E4-37, RB211-535E4-B-37, and RB211-
535E4-C-37 engines, determine if any part identified by part number
and serial number in Appendix 4 of RR Alert NMSB No. RB.211-72-
AH972, Revision 3, dated August 28, 2015, is installed on the
engine.
    (i) Do not return to service any engine with a part identified
in paragraph (e)(2) of this AD after the part reaches the
``Compliance Time'' date or cycles, whichever occurs first, as
specified in Appendix 4 of RR Alert NMSB No. RB.211-72-AH972,
Revision 3, dated August 28, 2015.
    (ii) For each part identified in paragraph (e)(2) of this AD
without a ``Compliance Time'' that has a lifing correction
identified, apply the lifing correction for each part using the
``Additional Life Consumed Flight Cycles'' specified in Appendix 4
of RR Alert NMSB No. RB.211-72-AH972, Revision 3, dated August 28,
2015.
    (3) For RR RB211-535E4-37 engines operated to Flight Profile G
with parts listed in Appendix 4 of RR Alert NMSB No. RB.211-72-
AH972, Revision 3, dated August 28, 2015, do the following:
    (i) Re-calculate the consumed cyclic life of the low-pressure
(LP) compressor shaft, LP turbine shaft, LP turbine disk Stage 2,

intermediate-pressure compressor rotor shaft Stage 1 to 6, high-
pressure (HP) compressor rotor disk Stage 1 and 2, HP compressor
rear rotor shaft assembly, and HP turbine disk as follows.
    (ii) Determine the Flight Profile G cycles in service (CIS).
Count all CIS accumulated since April 1, 2015, inclusive.
    (iii) Use the Flight Profile G cycles in service from paragraph
(e)(3)(ii) of this AD, the maximum approved lives in Appendix 2 of
RR Alert NMSB No. RB.211-72-AH972, Revision 3, dated August 28,
2015, and Figure 1 to paragraph (e) of this AD to calculate the new
consumed cyclic lives.
