[Docket No. FAA-2009-1067; Directorate Identifier 2009-NM-071-AD]
RIN 2120-AA64


Airworthiness Directives; Airbus Model A300 B2 and A300 B4 Series 
Airplanes; A300 B4-600, B4-600R, and F4-600R Series Airplanes; and 
Model C4-605R Variant F Airplanes (Collectively Called A300-600 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:

    Following the occurrence of cracks on the MLG [main landing 
gear] rib 5 RH [right-hand] and LH [left-hand] attachment fitting 
lower flanges, DGAC [Direction G[eacute]n[eacute]rale de l'Aviation 
Civile] France AD 2003-318(B) [parallel to part of FAA AD 2006-12-
13] was issued to require repetitive inspections and, as terminating 
action * * *[.]
    Subsequently, new cases of cracks were discovered during 
scheduled maintenance checks by operators of A300B4 and A300-600 
type aeroplanes on which the terminating action * * * [was] 
embodied. This condition, if not corrected, could affect the 
structural integrity of those aeroplanes.
* * * * *
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 January 4, 2010.

Discussion

    On May 31, 2006, we issued AD 2006-12-13, Amendment 39-14639 (71 FR 
33994, June 13, 2006). That AD required actions intended to address an 
unsafe condition on the products listed above.
    Since we issued AD 2006-12-13, the European Aviation Safety Agency 
(EASA), which is the Technical Agent for the Member States of the 
European

[[Page 59484]]

Community, has issued EASA Airworthiness Directive 2009-0081, dated 
April 6, 2009 (referred to after this as ``the MCAI''), to correct an 
unsafe condition for the specified products. The MCAI states:

    Following the occurrence of cracks on the MLG [main landing 
gear] rib 5 RH [right-hand] and LH [left-hand] attachment fitting 
lower flanges, DGAC [Direction G[eacute]n[eacute]rale de l'Aviation 
Civile] France AD 2003-318(B) [parallel to part of FAA AD 2006-12-
13] was issued to require repetitive inspections and, as terminating 
action, the embodiment of Airbus Service Bulletins (SB) A300-57-0235 
and A300-57-6088 * * *.
    Subsequently, new cases of cracks were discovered during 
scheduled maintenance checks by operators of A300B4 and A300-600 
type aeroplanes on which the terminating action SBs were embodied. 
This condition, if not corrected, could affect the structural 
integrity of those aeroplanes.
    To address and correct this condition, Airbus developed an 
inspection programme for aeroplanes modified in accordance with SB 
A300-57-0235 or A300-57-6088. This inspection programme was required 
to be implemented by DGAC France AD F-2005-113, original issue and 
later revision 1 [parallel to part of FAA AD 2006-12-13].
    A new EASA AD 2008-0111, superseding DGAC France AD F-2005-
113R1, was issued to reduce the applicability. For aeroplanes 
already compliant with DGAC France AD F-2005-113R1, no further 
action was required.
    Since EASA AD 2008-0111 issuance, Airbus reviewed the inspection 
programmes of SB A300-57A0246 and SB A300-57A6101 to introduce 
repetitive inspections including a new inspection technique for 
holes 47 and 54 and to reduce inspections threshold and intervals 
from 700 Flight Cycles (FC) to 400 FC until a revised terminating 
action is made available.

Required actions include contacting Airbus for repair instructions, if 
necessary, and doing the repair. You may obtain further information by 
examining the MCAI in the AD docket.

Relevant Service Information

    Airbus has issued Mandatory Service Bulletin A300-57A0246, 
including Appendixes 1 and 2, Revision 03, dated March 11, 2009; and 
Mandatory Service Bulletin A300-57A6101, including Appendixes 1 and 2, 
Revision 03, dated March 11, 2009. The actions described in this 
service information are intended to correct the unsafe condition 
identified in the MCAI.

Changes to Existing AD

    This proposed AD would retain certain requirements of AD 2006-12-
13. Since AD 2006-12-13 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
      Requirement in  AD 2006-12-13              this proposed AD
------------------------------------------------------------------------
Paragraph (e)...........................  paragraph (f).
Paragraph (f)...........................  paragraph (g).
Paragraph (g)...........................  paragraph (h).
Paragraph (h)...........................  paragraph (i).
Paragraph (i)...........................  paragraph (j).
Paragraph (j)...........................  paragraph (k).
Paragraph (k)...........................  paragraph (l).
Paragraph (l)...........................  paragraph (m).
------------------------------------------------------------------------

    We have also revised paragraph (i) of this NPRM to clarify the 
compliance times for airplanes that have not had the modification 
required by paragraph (i) of this NPRM accomplished before July 18, 
2006. We added the phrase, ``Except as required by paragraph (l) of 
this AD,'' to paragraph (i) of this NPRM. We have determined that this 
change will neither increase the economic burden on any operator nor 
increase the scope of the AD.
    We have also revised paragraph (o) of this AD to specify that no 
reporting is required.

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 155 products of U.S. registry.
    The actions that are required by AD 2006-12-13 and retained in this 
proposed AD take about 76 work-hours per product, at an average labor 
rate of $80 per work hour. Required parts cost about $10,270 per 
product. Based on these figures, the estimated cost of the currently 
required actions is $16,350 per product.
    We estimate that it would take about 3 work-hours per product to 
comply with the new basic requirements of this proposed AD. The average 
labor rate is $80 per work-hour. Based on these figures, we estimate 
the cost of the proposed AD on U.S. operators to be $37,200, or $240 
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,

[[Page 59485]]

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 57: Wings.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    Following the occurrence of cracks on the MLG [main landing 
gear] rib 5 RH [right-hand] and LH [left-hand] attachment fitting 
lower flanges, DGAC [Direction G[eacute]n[eacute]rale de l'Aviation 
Civile] France AD 2003-318(B) [parallel to part of FAA AD 2006-12-
13] was issued to require repetitive inspections and, as terminating 
action, the embodiment of Airbus Service Bulletins (SB) A300-57-0235 
and A300-57-6088 * * *.
    Subsequently, new cases of cracks were discovered during 
scheduled maintenance checks by operators of A300B4 and A300-600 
type aeroplanes on which the terminating action SB's were embodied. 
This condition, if not corrected, could affect the structural 
integrity of those aeroplanes.
    To address and correct this condition, Airbus developed an 
inspection programme for aeroplanes modified in accordance with SB 
A300-57-0235 or A300-57-6088. This inspection programme was required 
to be implemented by DGAC France AD F-2005-113, original issue and 
later revision 1 [parallel to part of FAA AD 2006-12-13].
    A new EASA [European Aviation Safety Agency] AD 2008-0111, 
superseding DGAC France AD F-2005-113R1, was issued to reduce the 
applicability. For aeroplanes already compliant with DGAC France AD 
F-2005-113R1, no further action was required.
    Since EASA AD 2008-0111 issuance, Airbus reviewed the inspection 
programmes of SB A300-57A0246 and SB A300-57A6101 to introduce 
repetitive inspections including a new inspection technique for 
holes 47 and 54 and to reduce inspections threshold and intervals 
from 700 Flight Cycles (FC) to 400 FC until a revised terminating 
action is made available.
    Required actions include contacting Airbus for repair 
instructions, if necessary, and doing the repair.

Restatement of Requirements of AD 2000-05-07:

    (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.

Repetitive Inspections

    (g) Perform a detailed inspection and a high-frequency eddy 
current (HFEC) inspection to detect cracks in Gear Rib 5 of the main 
landing gear (MLG) attachment fittings at the lower flange, in 
accordance with the Accomplishment Instructions of any applicable 
service bulletin listed in Table 1 and Table 2 of this AD, at the 
time specified in paragraph (g)(1) or (g)(2) of this AD. After April 
12, 2000 (the effective date of AD 2000-05-07, amendment 39-11616), 
only the service bulletins listed in Table 2 of this AD may be used. 
Repeat the inspections thereafter at intervals not to exceed 1,500 
flight cycles, until the actions specified in paragraph (i), (j), or 
(l) of this AD are accomplished.

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

     (1) For airplanes that have accumulated 20,000 or more total 
flight cycles as of March 9, 1998 (the effective date of AD 98-03-
06, amendment 39-10298): Inspect within 500 flight cycles after 
March 9, 1998.
    (2) For airplanes that have accumulated less than 20,000 total 
flight cycles as of March 9, 1998: Inspect prior to the accumulation 
of 18,000 total flight cycles, or within 1,500 flight cycles after 
March 9, 1998, whichever occurs later.

    Note 1: For the purposes of this AD, a detailed inspection is 
defined as: ``An

[[Page 59486]]

intensive visual examination of a specific structural area, system, 
installation, or assembly to detect damage, failure, or 
irregularity. Available lighting is normally supplemented with a 
direct source of good lighting at intensity deemed appropriate by 
the inspector. Inspection aids such as mirror, magnifying lenses, 
etc., may be used. Surface cleaning and elaborate access procedures 
may be required.''


    Note 2:  Accomplishment of the initial detailed and HFEC 
inspections in accordance with Airbus Service Bulletin A300-57A0234 
or A300-57A6087, both dated August 5, 1997, as applicable, is 
considered acceptable for compliance with the initial inspections 
required by paragraph (g) of this AD.

Repair for Any Crack Found During Inspections Required by Paragraph (g) 
of This AD

    (h) If any crack is detected during any inspection required by 
paragraph (g) of this AD, prior to further flight, accomplish the 
requirements of paragraph (h)(1) or (h)(2) of this AD, as 
applicable.
    (1) If a crack is detected at one hole only, and the crack does 
not extend out of the spotface of the hole, repair in accordance 
with the Accomplishment Instructions of the applicable service 
bulletin in Table 2 of this AD.
    (2) If a crack is detected at more than one hole, or if any 
crack at any hole extends out of the spotface of the hole, repair in 
accordance with a method approved by the Manager, International 
Branch, ANM-116, Transport Airplane Directorate, FAA, or the 
European Aviation Safety Agency (EASA) (or its delegated agent).

Terminating Modification for Repetitive Inspections Required by 
Paragraphs (g) and (j) of This AD

    (i) Except as required by paragraph (l) of this AD, prior to the 
accumulation of 21,000 total flight cycles, or within 2 years after 
October 20, 1999 (the effective date of AD 99-19-26, amendment 39-
11313), whichever occurs later: Modify Gear Rib 5 of the MLG 
attachment fittings at the lower flange in accordance with the 
Accomplishment Instructions of the applicable service bulletin in 
Table 3 of this AD. After July 18, 2006 (the effective date of AD 
2006-12-13), only Revision 04 of Airbus Service Bulletin A300-57-
6088, and Revisions 04 and 05 of Airbus Service Bulletin A300-57-
0235 may be used. Accomplishment of this modification constitutes 
terminating action for the repetitive inspection requirements of
