ACTION: Final rule. AGENCY: erowe on DSK2VPTVN1PROD with RULES SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above. 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: Surface defects were visually detected on the rudder of an A319 and an A321 in-service aeroplane. Investigation has determined that the defects reported on both rudders corresponded to areas that had been reworked in production. The investigation confirmed that the defects were as a result of de-bonding between the skin and honeycomb core. Such reworks were also performed on some rudders fitted on A310 and A300–600 aeroplanes. An extended de-bonding, if not detected and corrected, may degrade the structural integrity of the rudder. The loss of the rudder leads to degradation of the handling qualities and reduces the controllability of the aeroplane. * * * * * We are issuing this AD to require actions to correct the unsafe condition on these products.

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 June 29, 2011 (76 FR 38069). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: Surface defects were visually detected on the rudder of an A319 and an A321 in-service aeroplane. Investigation has determined that the defects reported on both rudders corresponded to areas that had been reworked in production. The investigation confirmed that the defects were as a result of de-bonding between the skin and honeycomb core. Such reworks were also performed on some rudders fitted on A310 and A300–600 aeroplanes. An extended de-bonding, if not detected and corrected, may degrade the structural integrity of the rudder. The loss of the rudder leads to degradation of the handling qualities and reduces the controllability of the aeroplane. To address this unsafe condition, EASA issued AD 2010–0002 [which corresponds to FAA AD 2010–16–13, Amendment 39–16390 (75 FR 49370, August 13, 2010)], superseding [EASA] AD 2009–0166, to require inspections of specific areas and, depending on findings, the application of corrective actions for those rudders where production reworks have been identified. PO 00000 Frm 00006 Fmt 4700 Sfmt 4700 This new [EASA] AD addresses the rudder population that has also been reworked in production but not included in the applicability of EASA AD 2010–0002. The required actions, for certain rudders, include vacuum loss inspections and elasticity laminate checker inspections for defects including de-bonding between the skin and honeycomb core of the rudder. The corrective action is contacting the FAA or EASA for repair instructions if any defects are found. For certain other rudders, the required actions include replacing the rudder with a serviceable rudder. We are considering similar rulemaking action on Model A319 and A321 airplanes. 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 38069, June 29, 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. 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 215 products of U.S. registry. We also estimate that it will take about 4 work- E:\FR\FM\23SER1.SGM 23SER1 Federal Register / Vol. 76, No. 185 / Friday, September 23, 2011 / Rules and Regulations 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 the AD on U.S. operators to be $73,100, or $340 per product. 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. erowe on DSK2VPTVN1PROD with RULES 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.

Reason (e) The mandatory continuing airworthiness information (MCAI) states: Surface defects were visually detected on the rudder of an A319 and an A321 in-service aeroplane. Investigation has determined that the defects reported on both rudders corresponded to areas that had been reworked in production. The investigation confirmed that the defects were as a result of de-bonding between the skin and honeycomb core. Such reworks were also performed on some rudders fitted on A310 and A300–600 aeroplanes. An extended de-bonding, if not detected and corrected, may degrade the structural integrity of the rudder. The loss of the rudder leads to degradation of the handling qualities and reduces the controllability of the aeroplane. * * * * * Compliance (f) You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.

SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above. 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: VerDate Mar<15>2010 14:40 Sep 22, 2011 Jkt 223001 BAE Systems have received reports of inservice failure of the Main Landing Gear (MLG) shock absorber lower attachment pin. * * * * * This condition, if not detected and corrected, could lead to a MLG collapse on the ground or during landing and consequently damage to the aeroplane or injury to the occupants. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective October 28, 2011. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of October 28, 2011. ADDRESSES: You may examine the AD docket on the Internet at https://www. regulations.gov or in person at the U.S. Department of Transportation, Docket Operations, M–30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue, SE., Washington, DC.

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 June 22, 2011 (76 FR 36398). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: BAE Systems have received reports of inservice failure of the Main Landing Gear (MLG) shock absorber lower attachment pin. Investigation has shown that the pin failures were due to corrosion. This condition, if not detected and corrected, could lead to a MLG collapse on the ground or during landing and consequently damage to the aeroplane or injury to the occupants. For the reasons described above, this AD requires repetitive [general visual] inspections [for damage (cracking, corrosion, and exposed material)] of the MLG shock absorber lower attachment pins and replacement, depending on findings. The replacement, if damage is found, consists of installing serviceable pins. 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 PO 00000 Frm 00009 Fmt 4700 Sfmt 4700 59011 received no comments on the NPRM (76 FR 36398, June 22, 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. 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 about 1 product of U.S. registry. We also estimate that it will take about 2 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 $170 per product. In addition, we estimate that any necessary follow-on actions would take about 2 work-hours and require parts costing $14,000, for a cost of $14,170 per product.

Airworthiness Directives; Airbus Model A300 B4-600, B4-600R, and
F4-600R Series Airplanes, and Model C4-605R Variant F Airplanes
(Collectively Called A300-600 Series Airplanes) and A310 Series
Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for the
products listed above. 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:

We are issuing this AD to require actions to correct the unsafe
condition on these products.

DATES: This AD becomes effective October 28, 2011.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of October 28,
2011.

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 June 29, 2011 (76 FR
38069). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:

Surface defects were visually detected on the rudder of an A319
and an A321 in-service aeroplane. Investigation has determined that
the defects reported on both rudders corresponded to areas that had
been reworked in production. The investigation confirmed that the
defects were as a result of de-bonding between the skin and
honeycomb core. Such reworks were also performed on some rudders
fitted on A310 and A300-600 aeroplanes.
An extended de-bonding, if not detected and corrected, may
degrade the structural integrity of the rudder. The loss of the
rudder leads to degradation of the handling qualities and reduces
the controllability of the aeroplane.
To address this unsafe condition, EASA issued AD 2010-0002
[which corresponds to FAA AD 2010-16-13, Amendment 39-16390 (75 FR
49370, August 13, 2010)], superseding [EASA] AD 2009-0166, to
require inspections of specific areas and, depending on findings,
the application of corrective actions for those rudders where
production reworks have been identified.
This new [EASA] AD addresses the rudder population that has also
been reworked in production but not included in the applicability of
EASA AD 2010-0002.

The required actions, for certain rudders, include vacuum loss
inspections and elasticity laminate checker inspections for defects
including de-bonding between the skin and honeycomb core of the rudder.
The corrective action is contacting the FAA or EASA for repair
instructions if any defects are found. For certain other rudders, the
required actions include replacing the rudder with a serviceable
rudder. We are considering similar rulemaking action on Model A319 and
A321 airplanes. 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 38069, June 29,
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.
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 215 products of U.S. registry.
We also estimate that it will take about 4 work-

[[Page 59009]]

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 the AD on U.S. operators to be $73,100, or $340
per product.

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 38069, June 29, 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.

Stabilizers.

Reason

(e) The mandatory continuing airworthiness information (MCAI)
states:
Surface defects were visually detected on the rudder of an A319
and an A321 in-service aeroplane. Investigation has determined that
the defects reported on both rudders corresponded to areas that had
been reworked in production. The investigation confirmed that the
defects were as a result of de-bonding between the skin and
honeycomb core. Such reworks were also performed on some rudders
fitted on A310 and A300-600 aeroplanes.
An extended de-bonding, if not detected and corrected, may
degrade the structural integrity of the rudder. The loss of the
rudder leads to degradation of the handling qualities and reduces
the controllability of the aeroplane.
