margins, an increase in flight crew
workload, discomfort to the flight crew,
or physical distress to the passengers or
cabin crew, possibly including non-fatal
injuries. Significant transients do not
require, in order to remain within or
recover to the normal flight envelope,
any of the following:
i. Exceptional piloting skill, alertness,
or strength.
ii. Forces applied by the pilot which
are greater than those specified in
§ 23.143(c).
iii. Accelerations or attitudes in the
airplane that might result in further
hazard to secured or non-secured
occupants.
It must also be demonstrated, through
tests and analysis, that no single failure
or malfunction or probable
combinations of failures of the auto
thrust system components results in the
probability for LOTC, or un-commanded
thrust changes and transients that result
in an LOTC event, to exceed the
following:
(1) Average Events per Million Hours: 10
(1×10¥05 per hour)
(2) Maximum Events per Million Hours: 100
(1×10¥04 per hour)
Note: The term ‘‘probable’’ in the context
of ‘‘probable combination of failures’’ does
not have the same meaning as used for a
safety assessment process. The term
‘‘probable’’ in ‘‘probable combination of
failures’’ means ‘‘foreseeable,’’ or those
failure conditions anticipated to occur one or
more times during the operational life of each
airplane.

Discussion
EASA, which is the Technical Agent
for the Member States of the European
Union, has issued EASA AD No. 2015–
0097, dated June 1, 2015, to correct an
unsafe condition for Agusta Model
A109A and A109A II helicopters. EASA
advises that during a scheduled 100flight-hour inspection on a Model
A109A II helicopter, unusual play was
detected on a part number (P/N) 109–
0130–11–7 slider. Further investigation
revealed excessive wear of the slider
broaching at the point of contact with
the tail rotor shaft. However, the cause
of the excessive play and wear has not
been determined.
This condition, if not detected and
corrected, could lead to reduced control
of the helicopter, EASA advises. EASA
consequently requires repetitive
inspections of slider P/N 109–0130–11–
7 more frequently than those performed
at the 100-flight-hour inspection and
corrective actions depending on the
findings. EASA advises that its AD is an
interim measure and further AD action
may follow.

Federal Register / Vol. 80, No. 236 / Wednesday, December 9, 2015 / Rules and Regulations
FAA’s Determination
These helicopters have been approved
by the aviation authority of Italy and are
approved for operation in the United
States. Pursuant to our bilateral
agreement with Italy, EASA, its
technical representative, has notified us
of the unsafe condition described in the
EASA AD. We are issuing 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 helicopters of
these same type designs.
Related Service Information
We reviewed AgustaWestland
Bollettino Tecnico No. 109–149, dated
May 29, 2015, for Model A109A and
A109A II helicopters. The bulletin states
that during a 100-flight-hour inspection
of a Model A109A II helicopter,
‘‘anomalous’’ play was found on a P/N
109–0130–11–7 slider. After the slider
was removed and inspected, extended,
unusual wear of the broaching in the
point of contact with the tail rotor shaft
was found. Agusta states that the
investigation is ongoing, but as a
precautionary measure it is reducing the
slider inspection intervals from 100
flight hours to 25 flight hours.
AD Requirements
This AD requires, within 25 hours
time-in-service (TIS) and thereafter at
intervals not to exceed 25 hours TIS,
inspecting the slider for play. If there is
any play that exceeds 2.3 millimeters
(0.09 inch), this AD requires replacing
the slider with an airworthy slider
before further flight.
wgreen on DSK2VPTVN1PROD with RULES
Interim Action
We consider this AD to be an interim
action. The design approval holder has
not determined the cause of the unsafe
condition identified in this AD. If a
cause is determined and actions
developed to address the cause, we
might consider additional rulemaking.
Costs of Compliance
We estimate that this AD will affect
36 helicopters of U.S. Registry and that
labor costs average $85 a work-hour.
Based on these estimates, we expect the
following costs:
• Inspecting the slider for play
requires 1 work-hour for a labor cost of
$85 per helicopter and $3060 for the
U.S. fleet.
• Replacing the slider requires 10
work-hours and $4068 in parts for a
total cost of $4918 per helicopter.
According to Agusta’s service
information, some of the costs of this
AD may be covered under warranty,
thereby reducing the cost impact on
VerDate Sep<11>2014
15:17 Dec 08, 2015
Jkt 238001
affected individuals. We do not control
warranty coverage by Agusta.
Accordingly, we have included all costs
in our cost estimate.
FAA’s Justification and Determination
of the Effective Date
Providing an opportunity for public
comments prior to adopting these AD
requirements would delay
implementing the safety actions needed
to correct this known unsafe condition.
Therefore, we find that the risk to the
flying public justifies waiving notice
and comment prior to the adoption of
this rule because the unsafe condition
can adversely affect control of the
helicopter and the required corrective
actions must be accomplished within 25
hours TIS. These helicopters have a
variety of uses, including search-andrescue and medical flights, and are
expected to accumulate 25 hours TIS
within a few weeks.
Since an unsafe condition exists that
requires the immediate adoption of this
AD, we determined that notice and
opportunity for public comment before
issuing this AD are impracticable and
contrary to the public interest and that
good cause exists for making this
amendment effective in less than 30
days.
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, 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 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.
We prepared an economic evaluation
of the estimated costs to comply with
this AD and placed it in the AD docket.

SUPPLEMENTARY INFORMATION:
SUMMARY:
Background
The authority for parts 730, 734, 736,
742, 744, and 745 of the EAR rests, in
part, on Executive Order 12938 of
November 14, 1994—Proliferation of
Weapons of Mass Destruction, 59 FR
59099, 3 CFR, 1994 Comp., p. 950 and
on annual notices continuing the
emergency declared in that executive
order. This rule revises the authority
citations for the affected parts to cite the
most recent such notice, which the
President signed on November 12, 2015.
This rule is purely non-substantive,
and makes no changes other than to
revise CFR authority citations for the
purpose of making the authority
citations current. It does not change the
text of any section of the EAR, nor does
it alter any right, obligation or
prohibition that applies to any person
under the EAR.
Rulemaking Requirements
1. Executive Orders 13563 and 12866

benefits of available regulatory
alternatives and, if regulation is

necessary, to select regulatory
approaches that maximize net benefits
(including potential economic,
environmental, public health and safety
effects, distributive impacts, and
equity). This rule does not impose any
regulatory burden on the public and is
consistent with the goals of Executive
Order 13563. This rule has been
determined to be not significant for
purposes of Executive Order 12866.
2. Notwithstanding any other
provision of law, no person is required
to respond to, nor shall any person be
subject to a penalty for failure to comply
with, a collection of information subject
to the requirements of the Paperwork
Reduction Act of 1995 (44 U.S.C. 3501
et seq.) (PRA), unless that collection of
information displays a currently valid
Office of Management and Budget
(OMB) Control Number. This rule does
not involve any collection of
information.
3. This rule does not contain policies
with Federalism implications as that
term is defined under Executive Order
13132.
4. The Department finds that there is
good cause under 5 U.S.C. 553(b)(B) to
waive the provisions of the
Administrative Procedure Act requiring
prior notice and the opportunity for
public comment because they are
unnecessary. This rule only updates
legal authority citations. It clarifies
information and is non-discretionary.
This rule does not alter any right,
obligation or prohibition that applies to
any person under the EAR. Because
these revisions are not substantive
changes, it is unnecessary to provide
notice and opportunity for public
comment. In addition, the 30-day delay
in effectiveness otherwise required by 5
U.S.C. 553(d) is not applicable because
this rule is not a substantive rule.
Because neither the Administrative
Procedure Act nor any other law
requires that notice of proposed
rulemaking and an opportunity for
public comment be given for this rule,
the analytical requirements of the
Regulatory Flexibility Act (5 U.S.C. 601
et seq.) are not applicable. Accordingly,
no Regulatory Flexibility Analysis is
required and none has been prepared.

Discussion
EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD No. 2015-0097, dated June 1, 2015,
to correct an unsafe condition for Agusta Model A109A and A109A II
helicopters. EASA advises that during a scheduled 100-flight-hour
inspection on a Model A109A II helicopter, unusual play was detected on
a part number (P/N) 109-0130-11-7 slider. Further investigation
revealed excessive wear of the slider broaching at the point of contact
with the tail rotor shaft. However, the cause of the excessive play and
wear has not been determined.
This condition, if not detected and corrected, could lead to
reduced control of the helicopter, EASA advises. EASA consequently
requires repetitive inspections of slider P/N 109-0130-11-7 more
frequently than those performed at the 100-flight-hour inspection and
corrective actions depending on the findings. EASA advises that its AD
is an interim measure and further AD action may follow.

precautionary measure it is reducing the slider inspection intervals
from 100 flight hours to 25 flight hours.
AD Requirements
This AD requires, within 25 hours time-in-service (TIS) and
thereafter at intervals not to exceed 25 hours TIS, inspecting the
slider for play. If there is any play that exceeds 2.3 millimeters
(0.09 inch), this AD requires replacing the slider with an airworthy
slider before further flight.
Interim Action
We consider this AD to be an interim action. The design approval
holder has not determined the cause of the unsafe condition identified
in this AD. If a cause is determined and actions developed to address
the cause, we might consider additional rulemaking.
Costs of Compliance
We estimate that this AD will affect 36 helicopters of U.S.
Registry and that labor costs average $85 a work-hour. Based on these
estimates, we expect the following costs:
Inspecting the slider for play requires 1 work-hour for a
labor cost of $85 per helicopter and $3060 for the U.S. fleet.
Replacing the slider requires 10 work-hours and $4068 in
parts for a total cost of $4918 per helicopter.
According to Agusta's service information, some of the costs of
this AD may be covered under warranty, thereby reducing the cost impact
on affected individuals. We do not control warranty coverage by Agusta.
Accordingly, we have included all costs in our cost estimate.
FAA's Justification and Determination of the Effective Date
Providing an opportunity for public comments prior to adopting
these AD requirements would delay implementing the safety actions
needed to correct this known unsafe condition. Therefore, we find that
the risk to the flying public justifies waiving notice and comment
prior to the adoption of this rule because the unsafe condition can
adversely affect control of the helicopter and the required corrective
actions must be accomplished within 25 hours TIS. These helicopters
have a variety of uses, including search-and-rescue and medical
flights, and are expected to accumulate 25 hours TIS within a few
weeks.
Since an unsafe condition exists that requires the immediate
adoption of this AD, we determined that notice and opportunity for
public comment before issuing this AD are impracticable and contrary to
the public interest and that good cause exists for making this
amendment effective in less than 30 days.
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, 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 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.
We prepared an economic evaluation of the estimated costs to comply
with this AD and placed it in the AD docket.
