[FR Doc. 2012–24173 Filed 10–1–12; 8:45 am] BILLING CODE 4910–13–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2012–1033; Directorate Identifier 2010–NM–266–AD] RIN 2120–AA64 Airworthiness Directives; Airbus Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to supersede an existing airworthiness directive (AD) that applies to all Airbus Model A330– 200 and –300 series airplanes, and Model A340–200 and –300 series airplanes. The existing AD currently requires repetitive inspections to detect discrepancies of the transfer tubes and the collar of the ball nut of the trimmable horizontal stabilizer actuator (THSA), and corrective action if necessary; repetitive inspections for discrepancies of the ball screw assembly, and corrective action if necessary; repetitive greasing of the THSA ball nut, and replacement of the THSA if necessary; and modification or replacement (as applicable) of the ball nut assembly, which would end certain repetitive inspections. Since we issued that AD, we have determined the repetitive inspections of the ball screw assembly (and corrective action if necessary) and repetitive greasing is needed for additional THSA nuts. This proposed AD would remove certain inspections, revise certain actions, and add airplanes to the applicability. We are proposing this AD to prevent degraded operation of the THSA, which wreier-aviles on DSK5TPTVN1PROD with PROPOSALS SUMMARY: VerDate Mar<15>2010 14:57 Oct 01, 2012 Jkt 229001 could result in reduced controllability of the airplane.

Discussion On March 17, 2005, we issued AD 2005–07–04, Amendment 39–14028 (70 FR 16104, March 30, 2005). That AD required actions intended to address an unsafe condition on the products listed above. Since we issued AD 2005–07–04, the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2010–0192 (corrected), dated October 11, 2010; and EASA Airworthiness Directive 2010– 0193 (corrected), dated October 11, 2010; (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: Several cases of transfer tube disconnection from the ball-nut of the trimmable horizontal stabilizer actuator (THSA) part number (P/N) 47172 and 47147– 400 were detected on the ground during greasing and maintenance. This condition is caused by water ingress into the ball-nut resulting in the jamming of the ball transfer circuit when the water freezes. If the three (independent) ball circuits fail, then the THSA will operate on a fail-safe nut. This nut (which operates without balls) would then jam after several movements on the screw of the THSA. This degraded operation is not detectable in the cockpit by the crew as long as the THSA does not jam and could damage the ball screw and the fail-safe nut. ´ To detect this unsafe condition, [Direccion ´ General de Aviacion Civil] DGAC France AD F–2001–356 [and F–2001–357] was issued to require repetitive inspections of the transfer tubes and their collars in order to detect at E:\FR\FM\02OCP1.SGM 02OCP1 60076 Federal Register / Vol. 77, No. 191 / Tuesday, October 2, 2012 / Proposed Rules an early stage any distortion or initiation of disconnection. Further to a new case of transfer tube disconnection, * * * [revised ADs] required an additional repetitive greasing task with reinforcement of the ball-nut maintenance greasing instructions. In addition, the electrical flight control computers monitor the operation of the THSA and the jamming of this actuator could be detected and indicated by messages on the maintenance system and on the [electronic centralized aircraft monitor] ECAM. In this case a mandatory inspection of the THSA is required before the next flight. DGAC France AD F–2002–038 [and F– 2002–037] required application of a final fix (related to inspection and greasing task required by DGAC France AD F–2001–356) [and F–2001–357] for the THSA P/N 47172 by application of Airbus modification 49590/ Service Bulletin (SB) A330–27–3085 [or SB A340–27–4089]. It changes the THSA P/N from 47172 to 47172–300. Later on, DGAC France AD F–2002–414R3 replaced the DGAC AD France F–2001– 356R2 and F–2002–038 [and DGAC France AD F2002–415R2 superseded DGAC France ADs F–2001–357R2 and F–2002–037] requiring: —the repetitive [detailed] inspection [for discrepancies] of all THSA P/N in service [for integrity of the primary and secondary load path and check the Checkable Shear Pins (CSPs)], and —the lubrication of some THSA P/N, and —the replacement of THSA P/N 47172, 47147–400 and 47147–2XX/–3XX [DGAC France AD F–2002–414R3 and F– 2002–415R2 correspond to FAA AD 2005– 07–04, Amendment 39–14028 (70 FR 16104, March 30, 2005).] Airbus has later introduced 4 new THSA P/N (47172–500, 47172–510, 47172–520 and 47172–530). This [EASA] AD retains the requirements of DGAC France AD F–2002–414R3 [and F– 2002–415R2], which is superseded, and requires repetitive inspections and lubrications of the new THSA P/N. The repetitive inspection and lubrication requirements for THSA P/N 47172–520 and 47172–530 shall [also] be included in the next Airworthiness Limitation Section (ALS) Part 4 revision. wreier-aviles on DSK5TPTVN1PROD with PROPOSALS * * * * * Corrective actions include replacing the THSA with a new THSA if cracks, dents, or corrosion are found, or if the feeler gage has failed at any of the four gaps. Corrective action is using a method approved by either the Manager, International Branch, ANM–116, Transport Airplane Directorate, FAA; or the EASA (or its delegated agent) for a finding of metallic debris, loose nut, damaged or missing lock washers, pins and parts, or incorrect installation of items. AD 2005–07–04, Amendment 39– 14028 (70 FR 16104, March 30, 2005), specified repetitive inspections for discrepancies. This proposed AD specifies repetitive inspections for the VerDate Mar<15>2010 14:57 Oct 01, 2012 Jkt 229001 integrity of the primary and secondary load path, and the CSPs, for certain airplanes. The unsafe condition is the degraded operation of the THSA, which could result in reduced controllability of the airplane. You may obtain further information by examining the MCAI in the AD docket.

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. Explanation of Updated Credit Language We have revised the heading and wording for paragraph (i) of this AD to provide appropriate credit for previous accomplishment of certain actions. This change does not affect the intent of that paragraph. Explanation of Change to Costs of Compliance Since issuance of AD 2005–07–04, Amendment 39–14028 (70 FR 16104, E:\FR\FM\02OCP1.SGM 02OCP1 Federal Register / Vol. 77, No. 191 / Tuesday, October 2, 2012 / Proposed Rules March 30, 2005), we have increased the labor rate used in the Costs of Compliance from $65 per work-hour to $85 per work-hour. The Costs of Compliance information, below, reflects this increase in the specified labor rate. Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 33 products of U.S. registry. The actions that are required by AD 2005–07–04, Amendment 39–14028 (70 FR 16104, March 30, 2005), and retained in this proposed AD take up to 36 workhours per product, at an average labor rate of $85 per work hour. Based on these figures, the estimated cost of the currently required actions is up to $3,060 per product. We estimate that it would take about 2 work-hours per product to comply with the new 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 $5,610, or $170 per product. We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this proposed AD. wreier-aviles on DSK5TPTVN1PROD with PROPOSALS 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. VerDate Mar<15>2010 14:57 Oct 01, 2012 Jkt 229001 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), 3. Will not affect intrastate aviation in Alaska, 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 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 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1.

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede an existing airworthiness directive
(AD) that applies to all Airbus Model A330-200 and -300 series
airplanes, and Model A340-200 and -300 series airplanes. The existing
AD currently requires repetitive inspections to detect discrepancies of
the transfer tubes and the collar of the ball nut of the trimmable
horizontal stabilizer actuator (THSA), and corrective action if
necessary; repetitive inspections for discrepancies of the ball screw
assembly, and corrective action if necessary; repetitive greasing of
the THSA ball nut, and replacement of the THSA if necessary; and
modification or replacement (as applicable) of the ball nut assembly,
which would end certain repetitive inspections. Since we issued that
AD, we have determined the repetitive inspections of the ball screw
assembly (and corrective action if necessary) and repetitive greasing
is needed for additional THSA nuts. This proposed AD would remove
certain inspections, revise certain actions, and add airplanes to the
applicability. We are proposing this AD to prevent degraded operation
of the THSA, which could result in reduced controllability of the
airplane.

DATES: We must receive comments on this proposed AD by November 16,
2012.

Discussion

On March 17, 2005, we issued AD 2005-07-04, Amendment 39-14028 (70
FR 16104, March 30, 2005). That AD required actions intended to address
an unsafe condition on the products listed above. Since we issued AD
2005-07-04, the European Aviation Safety Agency (EASA), which is the
Technical Agent for the Member States of the European Community, has
issued EASA Airworthiness Directive 2010-0192 (corrected), dated
October 11, 2010; and EASA Airworthiness Directive 2010-0193
(corrected), dated October 11, 2010; (referred to after this as ``the
MCAI''), to correct an unsafe condition for the specified products. The
MCAI states:

Several cases of transfer tube disconnection from the ball-nut
of the trimmable horizontal stabilizer actuator (THSA) part number
(P/N) 47172 and 47147-400 were detected on the ground during
greasing and maintenance.
This condition is caused by water ingress into the ball-nut
resulting in the jamming of the ball transfer circuit when the water
freezes.
If the three (independent) ball circuits fail, then the THSA
will operate on a fail-safe nut. This nut (which operates without
balls) would then jam after several movements on the screw of the
THSA.
This degraded operation is not detectable in the cockpit by the
crew as long as the THSA does not jam and could damage the ball
screw and the fail-safe nut.
To detect this unsafe condition, [Direcci[oacute]n General de
Aviaci[oacute]n Civil] DGAC France AD F-2001-356 [and F-2001-357]
was issued to require repetitive inspections of the transfer tubes
and their collars in order to detect at

[[Page 60076]]

an early stage any distortion or initiation of disconnection.
Further to a new case of transfer tube disconnection, * * *
[revised ADs] required an additional repetitive greasing task with
reinforcement of the ball-nut maintenance greasing instructions.
In addition, the electrical flight control computers monitor the
operation of the THSA and the jamming of this actuator could be
detected and indicated by messages on the maintenance system and on
the [electronic centralized aircraft monitor] ECAM. In this case a
mandatory inspection of the THSA is required before the next flight.
DGAC France AD F-2002-038 [and F-2002-037] required application
of a final fix (related to inspection and greasing task required by
DGAC France AD F-2001-356) [and F-2001-357] for the THSA P/N 47172
by application of Airbus modification 49590/Service Bulletin (SB)
A330-27-3085 [or SB A340-27-4089]. It changes the THSA P/N from
47172 to 47172-300.
Later on, DGAC France AD F-2002-414R3 replaced the DGAC AD
France F-2001-356R2 and F-2002-038 [and DGAC France AD F2002-415R2
superseded DGAC France ADs F-2001-357R2 and F-2002-037] requiring:

--the repetitive [detailed] inspection [for discrepancies] of all
THSA P/N in service [for integrity of the primary and secondary load
path and check the Checkable Shear Pins (CSPs)], and
--the lubrication of some THSA P/N, and
--the replacement of THSA P/N 47172, 47147-400 and 47147-2XX/-3XX

[DGAC France AD F-2002-414R3 and F-2002-415R2 correspond to FAA
AD 2005-07-04, Amendment 39-14028 (70 FR 16104, March 30, 2005).]

Airbus has later introduced 4 new THSA P/N (47172-500, 47172-
510, 47172-520 and 47172-530).
This [EASA] AD retains the requirements of DGAC France AD F-
2002-414R3 [and F-2002-415R2], which is superseded, and requires
repetitive inspections and lubrications of the new THSA P/N.
The repetitive inspection and lubrication requirements for THSA
P/N 47172-520 and 47172-530 shall [also] be included in the next
Airworthiness Limitation Section (ALS) Part 4 revision.

* * * * *
Corrective actions include replacing the THSA with a new THSA if
cracks, dents, or corrosion are found, or if the feeler gage has failed
at any of the four gaps. Corrective action is using a method approved
by either the Manager, International Branch, ANM-116, Transport
Airplane Directorate, FAA; or the EASA (or its delegated agent) for a
finding of metallic debris, loose nut, damaged or missing lock washers,
pins and parts, or incorrect installation of items. AD 2005-07-04,
Amendment 39-14028 (70 FR 16104, March 30, 2005), specified repetitive
inspections for discrepancies. This proposed AD specifies repetitive
inspections for the integrity of the primary and secondary load path,
and the CSPs, for certain airplanes. The unsafe condition is the
degraded operation of the THSA, which could result in reduced
controllability of the airplane. You may obtain further information by
examining the MCAI in the AD docket.

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.

Explanation of Updated Credit Language

We have revised the heading and wording for paragraph (i) of this
AD to provide appropriate credit for previous accomplishment of certain
actions. This change does not affect the intent of that paragraph.

Explanation of Change to Costs of Compliance

Since issuance of AD 2005-07-04, Amendment 39-14028 (70 FR 16104,

[[Page 60077]]

March 30, 2005), we have increased the labor rate used in the Costs of
Compliance from $65 per work-hour to $85 per work-hour. The Costs of
Compliance information, below, reflects this increase in the specified
labor rate.

Costs of Compliance

Based on the service information, we estimate that this proposed AD
would affect about 33 products of U.S. registry.
The actions that are required by AD 2005-07-04, Amendment 39-14028
(70 FR 16104, March 30, 2005), and retained in this proposed AD take up
to 36 work-hours per product, at an average labor rate of $85 per work
hour. Based on these figures, the estimated cost of the currently
required actions is up to $3,060 per product.
We estimate that it would take about 2 work-hours per product to
comply with the new 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 $5,610, or $170 per
product.
We have received no definitive data that would enable us to provide
cost estimates for the on-condition actions specified in this proposed
AD.

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),
3. Will not affect intrastate aviation in Alaska, 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 a regulatory evaluation of the estimated costs to
comply with this proposed AD and placed it in the AD docket.

``A visual examination of an interior or exterior area,
installation, or assembly to detect obvious damage, failure, or
irregularity. This level of inspection is made from within touching
distance unless otherwise specified. A mirror may be necessary to
ensure visual access to all surfaces in the inspection area. This
level of inspection is made under normally available lighting
conditions such as daylight, hangar lighting, flashlight, or
droplight and may require removal or opening of access panels or
doors. Stands, ladders, or platforms may be required to gain
proximity to the area being checked.''
