Airworthiness Directives; Gulfstream Aerospace LP (Type
Certificate Previously Held by Israel Aircraft Industries, Ltd.) Model
Galaxy, Gulfstream G150, and Gulfstream 200 Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the
products listed above. This proposed AD results from mandatory
continuing airworthiness information (MCAI) originated by an aviation
authority of another country to identify and correct an unsafe
condition on an aviation product. The MCAI describes the unsafe
condition as:

    A broken aileron servo actuator centering spring rod was
discovered on a model G100 aircraft during a routine scheduled
maintenance inspection. * * * This latent failure of a centering
spring rod, if not detected and corrected, in conjunction with the
disconnection of the normal mechanical control system of the same
servo actuator would lead to loss [of] control of the flight control
surface [aileron or elevator]. This condition would reduce the
control capability of the airplane and imposes a higher workload on
the flight crew reducing their ability to cope with adverse
operating conditions.

The proposed AD would require actions that are intended to address the
unsafe condition described in the MCAI.

DATES: We must receive comments on this proposed AD by August 29, 2011.

Discussion

    The Civil Aviation Authority (CAA), which is the aviation authority
for Israel, has issued Airworthiness Directives 27-10-11-03, dated
December 6, 2010; and 27-10-12-29, dated January 4, 2011 (referred to
after this as ``the MCAI''); to correct an unsafe

condition for the specified products. The MCAI states:

A broken aileron servo actuator centering spring rod was discovered
on a model G100 aircraft during a routine scheduled maintenance
inspection. This centering spring rod is common to all Gulfstream
Mid Cabin model (G100, G150 and G200) aileron control servo
actuators and the G200 elevator control servo actuator too. The
function of the centering spring rod is to maintain the affected
servo actuator and its associated flight control surface in a
centered position in the event of a disconnect of the normal
mechanical control system input from the flight crew to the same
servo actuator. This latent failure of a centering spring rod, if
not detected and corrected, in conjunction with the disconnection of
the normal mechanical control system of the same servo actuator
would lead to loss [of] control of the flight control surface/
aileron. This condition would reduce the control capability of the
airplane and imposes a higher workload on the flight crew reducing
their ability to cope with adverse operating conditions.

The required actions include a detailed inspection of the servo
actuator centering spring rods for the aileron and elevator to detect
fractured or broken rods, and replacing the rods if necessary. You may
obtain further information by examining the MCAI in the AD docket.

Relevant Service Information

    Gulfstream Aerospace LP has issued Gulfstream Service Bulletins
150-27-123; and 200-27-374; both Revision 1, both dated January 27,
2011. The actions described in this service information are intended to
correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with the State of Design Authority, we have
been notified of the unsafe condition described in the MCAI and service
information referenced above. We are proposing this AD because we
evaluated all pertinent information and determined an unsafe condition
exists and is likely to exist or develop on other products of the same
type design.

Differences Between This AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in
general, agree with their substance. But we might have found it
necessary to use different words from those in the MCAI to ensure the
AD is clear for U.S. operators and is enforceable. In making these
changes, we do not intend to differ substantively from the information
provided in the MCAI and related service information.
    We might also have proposed different actions in this AD from those
in the MCAI in order to follow FAA policies. Any such differences are
highlighted in a NOTE within the proposed AD.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD
would affect about 200 products of U.S. registry. We also estimate that
it would take about 19 work-hours per product to comply with the basic
requirements of this proposed AD. The average labor rate is $85 per
work-hour. Based on these figures, we estimate the cost of the proposed
AD on U.S. operators to be $323,000, or $1,615 per product.
    In addition, we estimate that any necessary follow-on actions would
take up to 20 work-hours per product, and require parts costing $0, for
a cost of $1,700 per product. We have no way of determining the number
of products that may need these actions. Where the service information
lists required parts costs that are covered under warranty, we have
assumed that there will be no charge for these costs. As we do not
control warranty coverage for affected parties, some parties may incur
costs higher than estimated here.

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 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;
    2. Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979); 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.
    We prepared a regulatory evaluation of the estimated costs to
comply with this proposed AD and placed it in the AD docket.

List of Subjects in 14 CFR Part 39

II. What action is the Agency taking?

    This document lists the statements of findings made by EPA after
review of notices submitted under TSCA section 5(a) that certain new
chemical substances or significant new uses are not likely to present
an unreasonable risk of injury to health or the environment. This
document presents statements of findings made by EPA during the period
from February 1, 2018 to March 31, 2018.

III. What is the Agency's authority for taking this action?

    TSCA section 5(a)(3) requires EPA to review a TSCA section 5(a)
notice and make one of the following specific findings:
     The chemical substance or significant new use presents an
unreasonable risk of injury to health or the environment;
     The information available to EPA is insufficient to permit
a reasoned evaluation of the health and environmental effects of the
chemical substance or significant new use;
     The information available to EPA is insufficient to permit
a reasoned evaluation of the health and environmental effects and the
chemical substance or significant new use may present an unreasonable
risk of injury to health or the environment;

     The chemical substance is or will be produced in
substantial quantities, and such substance either enters or may
reasonably be anticipated to enter the environment in substantial
quantities or there is or may be significant or substantial human
exposure to the substance; or
     The chemical substance or significant new use is not
likely to present an unreasonable risk of injury to health or the
environment.
    Unreasonable risk findings must be made without consideration of
costs or other non-risk factors, including an unreasonable risk to a
potentially exposed or susceptible subpopulation identified as relevant
under the conditions of use. The term ``conditions of use'' is defined
in TSCA section 3 to mean ``the circumstances, as determined by the
Administrator, under which a chemical substance is intended, known, or
reasonably foreseen to be manufactured, processed, distributed in
commerce, used, or disposed of.''
    EPA is required under TSCA section 5(g) to publish in the Federal
Register a statement of its findings after its review of a TSCA section
5(a) notice when EPA makes a finding that a new chemical substance or
significant new use is not likely to present an unreasonable risk of
injury to health or the environment. Such statements apply to PMNs,
MCANs, and SNUNs submitted to EPA under TSCA section 5.
    Anyone who plans to manufacture (which includes import) a new
chemical substance for a non-exempt commercial purpose and any
manufacturer or processor wishing to engage in a use of a chemical
substance designated by EPA as a significant new use must submit a
notice to EPA at least 90 days before commencing manufacture of the new
chemical substance or before engaging in the significant new use.
    The submitter of a notice to EPA for which EPA has made a finding
of ``not likely to present an unreasonable risk of injury to health or
the environment'' may commence manufacture of the chemical substance or
manufacture or processing for the significant new use notwithstanding
any remaining portion of the applicable review period.

IV. Statements of Administrator Findings Under TSCA Section 5(a)(3)(C)

    In this unit, EPA provides the following information (to the extent
that such information is not claimed as Confidential Business
Information (CBI)) on the PMNs, MCANs and SNUNs for which, during this
