Before using any approved AMOC on any
airplane to which the AMOC applies, notify
your appropriate principal inspector (PI) in
the FAA Flight Standards District Office
(FSDO), or lacking a PI, your local FSDO.
(2) Airworthy Product: For any requirement
in this AD to obtain corrective actions from
a manufacturer or other source, use these
actions if they are FAA-approved. Corrective
actions are considered FAA-approved if they
are approved by the State of Design Authority
(or their delegated agent). You are required
to assure the product is airworthy before it
is returned to service.
(3) Reporting Requirements: For any
reporting requirement in this AD, a federal
agency may not conduct or sponsor, and a

Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
AGENCY:
We are adopting a new
airworthiness directive (AD) for certain
Model ATR42 and ATR72 airplanes.
This 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:
SUMMARY:
One ATR operator has experienced inflight elevator travel limitations with unusual
effort being necessary on pitch axis to control
the aeroplane, while the ‘‘pitch mistrim’’
message appeared on the ADU [advisory
display unit] display. The elevators seemed
to be jammed.
During the post-flight inspection, it was
discovered that the LH [left-hand] elevator
lower stop assembly was broken at the level
of the angles, which may have prevented the
elevator to respond normally to the flight
control input.
This condition, if not detected and
corrected, could lead to reduced control of
the aeroplane.
*
*
*
*
*
We are issuing this AD to require
actions to correct the unsafe condition
on these products.
DATES: This AD becomes effective
December 15, 2011.
The Director of the Federal Register
approved the incorporation by reference
of certain publications listed in this AD
as of December 15, 2011.
ADDRESSES: You may examine the AD
docket on the Internet at https://

We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would
apply to the specified products. That
NPRM was published in the Federal
Register on August 5, 2011 (76 FR
47520). That NPRM proposed to correct
an unsafe condition for the specified
products. The MCAI states:
One ATR operator has experienced inflight elevator travel limitations with unusual
effort being necessary on pitch axis to control
the aeroplane, while the ‘‘pitch mistrim’’
message appeared on the ADU display. The
elevators seemed to be jammed.
During the post-flight inspection, it was
discovered that the LH elevator lower stop
assembly was broken at the level of the
angles, which may have prevented the
elevator to respond normally to the flight
control input.
This condition, if not detected and
corrected, could lead to reduced control of
the aeroplane.
For the reasons described above, and as a
precautionary measure, this [EASA] AD
requires a one-time [general visual and
detailed] inspection [for damaged angles] of
the elevator hinge fittings and the reporting
of all findings. Depending on the results,
further action may be considered.
Corrective actions also include
replacement of damaged angles with
serviceable parts; and a detailed
inspection of adjacent areas for damage,
and repair if necessary. You may obtain
further information by examining the
MCAI in the AD docket.
Comments
We gave the public the opportunity to
participate in developing this AD. We
received no comments on the NPRM (76
FR 47520), August 5, 2011) or on the
determination of the cost to the public.
Conclusion
We reviewed the available data and
determined that air safety and the
public interest require adopting the AD
as proposed.
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.
E:\FR\FM\10NOR1.SGM

Federal Register / Vol. 76, No. 218 / Thursday, November 10, 2011 / Rules and Regulations
We might also have required different
actions in this AD from those in the
MCAI in order to follow our FAA
policies. Any such differences are
highlighted in a NOTE within the AD.
under the criteria of the Regulatory
Flexibility Act.
We prepared a regulatory evaluation
of the estimated costs to comply with
this AD and placed it in the AD docket.
Costs of Compliance
We estimate that this AD will affect
86 products of U.S. registry. We also
estimate that it will take about 4 workhours per product to comply with the
basic requirements of this AD. The
average labor rate is $85 per work-hour.
Based on these figures, we estimate the
cost of this AD to the U.S. operators to
be $29,240, or $340 per product.
In addition, we estimate that any
necessary follow-on actions would take
about 60 work-hours and require parts
costing $960, for a cost of $6,060 per
product. We have no way of
determining the number of products
that may need these actions.
Examining the AD Docket
You may examine the AD docket on
the Internet at https://
www.regulations.gov; or in person at the
Docket Operations office between 9 a.m.
and 5 p.m., Monday through Friday,
except Federal holidays. The AD docket
contains the NPRM (76 FR 47520,
August 5, 2011), the regulatory
evaluation, any comments received, and
other information. The street address for
the Docket Operations office (telephone
(800) 647–5527) is in the ADDRESSES
section. Comments will be available in
the AD docket shortly after receipt.
emcdonald on DSK5VPTVN1PROD with RULES
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); and
3. Will not have a significant
economic impact, positive or negative,
on a substantial number of small entities

That AD requires a daily check of the
tail rotor (T/R) pitch control rod (control
rod) outboard spherical bearing
(bearing) for play. If play exists, that AD
requires measuring the bearing’s radial
and axial play. Since that AD was
issued, an incident occurred where the
pilot of a Model AS350 helicopter felt
vibrations in the anti-torque pedal in
flight, resulting in a precautionary
landing. An investigation determined
that the control rod showed extensive
wear on the ball-joint. This superseding
AD maintains the requirements of the
existing AD, and expands the
applicability to include the Model
AS355NP helicopter and additional
part-numbered control rods. The actions
specified by this AD are intended to
prevent failure of a control rod, loss of
T/R control, and subsequent loss of
control of the helicopter.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM was published in the Federal Register on August 5, 2011 (76
FR 47520). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
One ATR operator has experienced in-flight elevator travel
limitations with unusual effort being necessary on pitch axis to
control the aeroplane, while the ``pitch mistrim'' message appeared
on the ADU display. The elevators seemed to be jammed.
During the post-flight inspection, it was discovered that the LH
elevator lower stop assembly was broken at the level of the angles,
which may have prevented the elevator to respond normally to the
flight control input.
This condition, if not detected and corrected, could lead to
reduced control of the aeroplane.
For the reasons described above, and as a precautionary measure,
this [EASA] AD requires a one-time [general visual and detailed]
inspection [for damaged angles] of the elevator hinge fittings and
the reporting of all findings. Depending on the results, further
action may be considered.
Corrective actions also include replacement of damaged angles with
serviceable parts; and a detailed inspection of adjacent areas for
damage, and repair if necessary. You may obtain further information by
examining the MCAI in the AD docket.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (76 FR 47520), August 5,
2011) or on the determination of the cost to the public.
Conclusion
We reviewed the available data and determined that air safety and
the public interest require adopting the AD as proposed.
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.
[[Page 70045]]
We might also have required different actions in this AD from those
in the MCAI in order to follow our FAA policies. Any such differences
are highlighted in a NOTE within the AD.
Costs of Compliance
We estimate that this AD will affect 86 products of U.S. registry.
We also estimate that it will take about 4 work-hours per product to
comply with the basic requirements of this AD. The average labor rate
is $85 per work-hour. Based on these figures, we estimate the cost of
this AD to the U.S. operators to be $29,240, or $340 per product.
In addition, we estimate that any necessary follow-on actions would
take about 60 work-hours and require parts costing $960, for a cost of
$6,060 per product. We have no way of determining the number of
products that may need these actions.
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); 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 AD and placed it in the AD docket.
Examining the AD Docket
You may examine the AD docket on the Internet at https://www.regulations.gov; or in person at the Docket Operations office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains the NPRM (76 FR 47520, August 5,
2011), the regulatory evaluation, any comments received, and other
information. The street address for the Docket Operations office
(telephone (800) 647-5527) is in the ADDRESSES section. Comments will
be available in the AD docket shortly after receipt.
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 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 adding the following new AD:
2011-23-10 ATR-GIE Avions de Transport R[eacute]gional: Amendment
39-16861. Docket No. FAA-2011-0721; Directorate Identifier 2010-NM-
217-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective December
15, 2011.
Affected ADs
(b) None.
Applicability
(c) This AD applies to ATR-GIE Avions de Transport
R[eacute]gional Model ATR42-200, -300, -320, and -500 airplanes, all
manufacturer serial numbers (MSN) up to MSN 643 inclusive; and Model
ATR72-101, -102, -201, -202, -211, -212, and -212A airplanes, all
MSNs up to MSN 728 inclusive; certificated in any category.
Subject
(d) Air Transport Association (ATA) of America Code 55:
Stabilizers.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
One ATR operator has experienced in-flight elevator travel
limitations with unusual effort being necessary on pitch axis to
control the aeroplane, while the ``pitch mistrim'' message appeared
on the ADU [advisory display unit] display. The elevators seemed to
be jammed.
During the post-flight inspection, it was discovered that the LH
[left-hand] elevator lower stop assembly was broken at the level of
the angles, which may have prevented the elevator to respond
normally to the flight control input.
This condition, if not detected and corrected, could lead to
reduced control of the aeroplane.
