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.
