RIN 2120-AA64

 
Airworthiness Directives; Airbus Model A330-200 and -300 and 
A340-200 and -300 Series Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the 
products listed above that would supersede an existing AD. This 
proposed 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:

    A debonding area was detected on the RH [right-hand] elevator of 
an A340 in-service aeroplane during a scheduled maintenance task 
inspection.
    Investigation has revealed that this debonding may have been 
caused by water ingress and, if not detected and corrected, might 
compromise the structural integrity of the elevators [and could 
result in reduced controllability of the airplane].

    The proposed AD would require actions that are intended to address 
the unsafe condition described in the MCAI.

DATES: We must receive comments on this proposed AD by October 25, 
2010.

Discussion

    On September 29, 2005, we issued AD 2005-20-32, Amendment 39-14329 
(70 FR 59263, October 12, 2005). That AD required actions intended to 
address an unsafe condition on the products listed above.
    Since we issued AD 2005-20-32, we have determined that the existing 
inspection of the upper and lower elevator skin panels needs to be a 
repetitive inspection in order to adequately address the identified 
unsafe condition. We have also added airplane models to the 
applicability of this proposed AD, and we have identified additional 
affected elevators in Table 1 of this proposed AD. The European 
Aviation Safety Agency (EASA), which is the Technical Agent for the 
Member States of the European Community, has issued EASA Airworthiness 
Directive 2009-0255, dated December 1, 2009 (referred to after this as 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    A debonding area was detected on the RH [right-hand] elevator of 
an A340 in-service aeroplane during a scheduled maintenance task 
inspection.
    Investigation has revealed that this debonding may have been 
caused by water ingress and, if not detected and corrected, might 
compromise the structural integrity of the elevators [and could 
result in reduced controllability of the airplane].
    DGAC [Direction G[eacute]n[eacute]rale de l'Aviation Civile] 
France AD F-2004-118 R1 (EASA approval N. 2004-10125) required a 
one-time inspection of elevators skin panels installed on MSN up to 
091, to detect potential liquid ingress and repair as necessary, in 
accordance with Airbus inspection service bulletins (ISB) A330-55-
3032 and A340-55-4029.
    Following the AD issuance, further in-service experience has 
shown that in order to ensure the structural integrity of all A330/
A340 elevators skin panels with sandwich construction (excluding 
A340-500/-600), it is necessary to perform the same elevators panels 
inspection and to repair as necessary, but in a repetitive manner.
    The aim of this AD, which supersedes DGAC France AD F-2004-118 
R1, is to require this additional inspection program in order to 
maintain the structural integrity of the elevators.

The required actions include repetitive special detailed inspections 
and repetitive re-protection of the elevator assembly. The special 
detailed inspections consist of the following actions:


[[Page 54537]]


     Repetitive endoscopic inspections for damage (such as a 
scratch, disbonding, or a tear) of the inner skin of the upper and 
lower elevator panels on both sides of the airplane, and if any damage 
is found, contacting Airbus for instructions and doing the 
instructions.
     Repetitive tap tests for debonding in the inner side of 
the upper and lower elevator panels on both sides, and if any debonding 
is found, contacting Airbus for instructions and doing the 
instructions.
     Repetitive thermographic inspections for indications of 
trapped water in the upper and lower elevator panels on both sides of 
the airplane, and if any indications of trapped water are found, doing 
applicable corrective actions (including, but not limited to, repeating 
the thermographic inspection to determine the size of the damaged area, 
doing a general visual inspection to determine if there is an existing 
repair, contacting Airbus for instructions and doing the instructions, 
re-protecting the affected surfaces, and repairing holes).
     Repetitively re-protect the elevator assembly (including 
doing a general visual inspection to determine damage and repair if 
necessary, a general visual inspection to determine if the drainage 
holes are clean and not obstructed and cleaning the drainage holes if 
necessary, a general visual inspection to determine the status of the 
static discharges contour and sealing the static discharges contour if 
necessary, and installing front spar access hole covers).
    You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Airbus has issued Mandatory Service Bulletins A330-55-3039 and 
A340-55-4035, both including Appendix 1, both dated August 7, 2009. The 
actions described in the service information are intended to correct 
the unsafe condition identified in the MCAI.

Explanation of Change to This AD

    We have removed the ``Service Bulletin Reference'' paragraph from 
the ``Restatement of Requirements of AD 2005-20-32'' section of this 
AD. That paragraph was identified as paragraph (f) in AD 2005-20-32. 
Instead, we have provided the full service bulletin citations 
throughout this AD.

Change to Existing AD

    This proposed AD would retain the requirements of AD 2005-20-32. 
Since AD 2005-20-32 was issued, the AD format has been revised, and 
certain paragraphs have been rearranged. As a result, the corresponding 
paragraph identifiers have changed in this proposed AD, as listed in 
the following table:

                      Revised Paragraph Identifiers
------------------------------------------------------------------------
                                      Corresponding  requirement in this
    Requirement in AD 2005-20-32                 proposed AD
------------------------------------------------------------------------
          paragraph (f)(1)                        paragraph (g)
          paragraph (f)(2)                        paragraph (h)
             paragraph (g)                        paragraph (i)
             paragraph (h)                        paragraph (j)
             paragraph (i)                        paragraph (k)
------------------------------------------------------------------------

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.

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 proposed different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
highlighted in a Note within the proposed AD.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 56 products of U.S. registry.
    The actions that are required by AD 2005-20-32 and retained in this 
proposed AD take about 1 work-hour 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 $85 per product.
    We estimate that it would take about 14 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 $66,640, or $1,190 
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 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); 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 proposed AD and placed it in the AD docket.

Subject

    (d) Air Transport Association (ATA) of America Code 55: 
Stabilizers.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:

    A debonding area was detected on the RH [right-hand] elevator of 
an A340 in-service aeroplane during a scheduled maintenance task 
inspection.
    Investigation has revealed that this debonding may have been 
caused by water ingress and, if not detected and corrected, might 
compromise the structural integrity of the elevators [and could 
result in reduced controllability of the airplane].

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.

Restatement of Requirements of AD 2005-20-32

Service Bulletin Exceptions for Airbus Service Bulletin A330-55-
3032 and Airbus Service Bulletin A340-55-4029

    (g) Where Airbus Service Bulletin A330-55-3032 and Airbus 
Service Bulletin A340-55-4029, both dated December 22, 2003, 
recommend contacting Airbus for appropriate action: Before further 
flight, repair the condition according to a method approved by the 
Manager, International Branch, ANM-116, Transport Airplane 
Directorate, FAA; or the Direction G[eacute]n[eacute]rale de 
l'Aviation Civile (or its delegated agent), or EASA (or its 
delegated agent).
    (h) Although Airbus Service Bulletin A330-55-3032 and Airbus 
Service Bulletin A340-55-4029, both dated December 22, 2003, specify 
to submit certain information to the manufacturer, this AD does not 
include that requirement.

Determining Part Number, Serial Number

    (i) For Model A330-201, -202, -203, -223, -243, -301, -321, -
322, -323, -341, -342, and -343 airplanes; and Model A340-211, -212, 
-213, -311, -312, and -313 airplanes: At the later of the times 
specified in paragraphs (i)(1) and (i)(2) of this AD, perform an 
inspection to determine the part number and serial number of the 
left- and right-hand elevator assemblies. A review of airplane 
maintenance records is acceptable in lieu of this inspection if the 
part number and serial number of each elevator assembly can be 
conclusively determined from that review. If neither elevator 
assembly has a part number and serial number combination identified 
in Table 2 of this AD, no further action is required by this 
paragraph. If either elevator assembly has a part number and serial 
number combination identified in Table 2 of this AD, do paragraph 
(j) of this AD. Doing the actions in paragraph (k) of this AD 
terminates the requirements of paragraph (i) of this AD.
    (1) Within 10 years after the date of the first flight of the 
airplane, or before the accumulation of 12,000 total flight cycles, 
whichever is first.
    (2) Within 18 months after the November 16, 2005 (the effective 
date of AD 2005-20-32).

    Note 1: For the purposes of this AD, a general visual inspection 
is: ``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.''

New Requirements of This AD

Repetitive Inspection

    (k) Within the applicable time in paragraph (k)(1) or (k)(2) of 
this AD, do a special detailed inspection for discrepancies 
(scratches, debonding, tears, and indications of trapped water), on 
the elevator upper and lower skin panels, in accordance with the 
Accomplishment Instructions of Airbus Mandatory Service Bulletin
